The aim of this work is to evaluate the effect of adding different amounts of SiO2 nanoparticles (NPs) during the synthesis of polylactic acid (PLA) and polypropylene (PP) blends on the proccesability. The analysis was carried out in terms of the morphological, rheological and mechanical properties as well as their potential applications for packaging. To reach this goal, it was initially realized an optimization of sol-gel parameters to produce of SiO2 NPs with a particle size < 20 nm. Thereafter, different quantities of SiO2 NPs (1, 2, 3, 5 wt.%) were incorporated into PLA matrix through melt mixing process to achieve pellets and finally, it was realized the polymer blend to produce PP100-x(PLA-SiO2)x nanocomposites (x = 5, 10 and 20 wt.%, of PLA-SiO2 pellets). It was found that the addition of SiO2 into PLA matrix improves the crystallinity percentage, from 10 to 77%, depending on the SiO2 quantity; however, it also restricts the movement of PLA chains favoring a viscous behavior. A high dispersion of PLA-SiO2 systems into PP matrix was obtained in composites containing 1 wt.% of SiO2. The presence of inorganic nanostructures modified the dipole-dipole interaction between organic components affecting the microstructure and thermal stability (lower Td). The observed interaction and high dispersion with low amounts of SiO2 NPs (1 wt.%), led to improve the interfacial miscibility, which in turn enhanced the mechanical properties in the PP90(PLA-SiO2)10 nanocomposites, compared to PP and PLA. The results indicate that at the end of product shelf-life, this composition can promote a faster degradation in contrast with pure PP and PP-PLA composites.

Academy–industry collaborations (AICs) play a crucial role in the creation of new knowledge, by transferring this knowledge to the society and bringing into line theory and practice. Although in the state-of-the-art exists a number of efforts to analyze different factors that influence these collaborations, little attention has been paid in the application of dynamic capabilities (DCs) as an emerging tool to identify strategic elements in public research institutes (PRIs). Aiming to fill this literature gap, in this study, DCs methodology was applied to the Mexican PRI in order to classify the research activities into these strategies. A second stage was carried out to determine the influence of each DC in the global productivity and knowledge integration or transfer. The relationship between the variables was statistically analyzed using one-way analysis of variance (ANOVA) and Pearson’s correlation coefficient. The main findings of this study showed that sensing and reconfiguration capabilities have a direct interaction on the global productivity and knowledge integration or transfer of the Mexican PRI, whereas the seizing capabilities present a weak impact on these items. The proper application of the DCs framework, as a substantial instrument for the PRI, opens up an alternative to identify that the main activities should receive special attention during the strategic planning process. These strategies can improve academy–industry collaborations by promoting the process of global knowledge and technology development.

The main purpose of this work was to synthesize ZnO nanoparticles (NPs) in situ into a chitosan (CS) matrix to obtain highly dispersed antibacterial composites by the sol–gel technique. These composites were characterized by their thermal, structural, morphological and optical properties. NPs were subsequently used and added into polyvinyl alcohol (PVA) in order to obtain electrospun fibers. Previously, it was determined the adequate PVA/CS ratio and changes in their morphological features in dependence of molecular weight of PVA and electrospinning parameters to avoid the beads and spindle-like defects in the final fibers. Then, optimal conditions were used to fabricate PVA/in situ ZnO:CS nanofiber composites. The hydrogen bonding interaction governs the ZnO:CS system, which forms a combination between flower-type and agglomerated rod morphologies. It was found that CS promotes the crystallinity of ZnO NPs maintaining the hexagonal phase. The addition of ZnO into the CS matrix was performed via weak interactions by stabilizing the hybrid compound after the second decomposition stage when the mass loss is above 50%. Free-defects uniform fibers with an improvement in hardness as well as in the elastic modulus was obtained in the electrospun PVA/in situ ZnO:CS fibers. The presence of ZnO NPs improves the spinnability in the fiber nanocomposites with an average diameter of 223 nm. PVA/in situ ZnO:CS mats displayed an inhibition of bacterial growth of Escherichia coli and Staphylococcus aureus.

Traditionally, biochar is generally proposed to substitute Canadian Sphagnum peat moss. Sugarcane bagasse, filter press mud and sugarcane bagasse ash were mixed in different ratios and proposed as an alternative to substitute commercial Sphagnum peat moss (SPM) for the soilless cultivation of tomato (S. lycopersicum Linnaeus). The choice of the agroindustrial waste ratio was performed from physical-chemical sample characterization. During vegetable production, an adequate ratio was evaluated based on plant height, substrate pH, number of leaves, yield, and fruit size. The addition of essential macro- and micro-nutrients was performed manually. The results show that as-received materials contain different minerals with a structure that corresponds to the quartz, cristobalite, and feldspar phases. A morphology composed of lamellate structures was observed for sugarcane bagasse, whereas the filter press mud and the sugarcane bagasse ash presented compact agglomerates with a surface area of 1.60, 3.78, and 1.07 m2 g−1, respectively. The properties of each component promote the water adsorption, retention and releasing capacity. Important differences were observed as the quantity of filter press mud increased, but also it is required an amount of sugarcane bagasse above of 18 wt% to reach a superior performance. This work demonstrated that, in adequate quantities, agroindustrial wastes can be used as a soilless substrate for growing tomatoes in greenhouse, reducing their disposal problems.

In this work, the optimal conditions of synthesizing and purifying carbon nanotubes (CNTs) from ferrocene were selected at the first stage, where decomposition time, argon fluxes, precursor amounts, decomposition temperature (at 1023 K and 1123 K), and purification process (HNO3 + H2SO4 or HCl + H2O2), were modulated through chemical vapor deposition (CVD) and compared to commercial CNTs. The processing temperature at 1123 K and the treatment with HCl + H2O2 were key parameters influencing the purity, crystallinity, stability, and optical/electrical properties of bamboo-like morphology CNTs. Selected multiwalled CNTs (MWCNTs), from 1 to 20 wt%, were electropolymerized through in-situ polarization with conductive polymers (CPs), poly(aniline) (PANI) and poly(pyrrole) (PPy), for obtaining composites. In terms of structural stability and electrical properties, MWCNTs obtained by CVD were found to be better than commercial ones for producing CPs composites. The CNTs addition in both polymeric matrixes was of 6.5 wt%. In both systems, crystallinity degree, related to the alignment of PC chains on MWCNTs surface, was improved. Electrical conductivity, in terms of the carrier density and mobility, was adequately enhanced with CVD CNTs, which were even better than the evaluated commercial CNTs. The findings of this study demonstrate that synergistic effects among the hydrogen bonds, stability, and conductivity are better in PANI/MWCNTs than in PPy/MWCNTs composites, which open a promissory route to prepare materials for different technological applications.

La0.7-xPrxCa0.3MnO3 (LPCM) perovskites previously synthesized by the microwave-assisted method at 4 min and with different stoichiometry (x = 0.35, 0.52 and 0.63) were evaluated through thermogravimetric analysis (TGA), electrical conductivity, thermal expansion coefficient (TEC), scanning electron microscopy (SEM), Brunauer- Emmet- Teller (BET) analysis and electrochemical impedance spectroscopy (EIS) using yttria stabilized zirconia (YSZ) as an electrolyte. The results are discussed in terms of the potential as cathode material to be applied in solid oxide fuel cells (SOFCs) applications at temperatures from 600 to 800 °C. Results derived from TGA showed that Pr promotes the uncoupling oxygen and oxygen vacancies favoring the fuel combusting. Also, TEC analysis revealed adequate stability between the YSZ electrolyte and the La0.7-xPrxCa0.3MnO3 to avoid cracking or failing, especially with high amount of Pr. The transition in morphology from irregular to regular shapes improves the BET and Barret- Joyner- Halenda (BJH) surfaces and promotes the triple phase boundary (TPB) connectivity. The electrical conductivity correlated to the availability in oxygen vacancies showed maximum conductivities in the order of 10−2 S cm−1. Activation energy (Ea) was found to be reduced with a minimum quantity of Pr (0.071 eV). EIS results indicate that the oxygen vacancies in the LPCM/YSZ system were better promoted with the highest amount of Pr = 0.63 (η = 0.9 V, 800 °C and 0.06 V of amplitude) in comparison with the minimum, Pr = 0.35 (η = 1.2 V, 800 °C and 0.06 V of amplitude).

Electrospinning technique was used to obtain a new class of biopolymer/inorganic nanoparticle hybrid fibers fabricated by using poly(lactic acid) (PLA) as the biopolymer matrix and lanthanum phosphate nanoparticles (LaPO4) as energy down-converting materials. Before being incorporated and electrospun with the PLA, the LaPO4 nanostructures obtained from microwave-assisted hydrothermal method were studied to have a depth understanding related to their synthesis parameters, since it is known they adopt different structures and morphologies with the temperature and pH. Highly hydrophobic samples of LaPO4 nanoparticles in hexagonal and monoclinic phases with mixed morphologies (rods and semi-spherical) were detected in samples calcined at 400 °C while those calcined at 600 °C consisted mainly in monoclinic phase with semi-spherical morphologies. Smallest particles in semi-spherical and orthorhombic morphologies obtained at pH 1 and 11 were detected after processing them through electrospinning technique and distributed uniformly into the PLA. The vibrational analysis suggested that the ester group (RCOOR') in PLA plays a key role in the interaction with the LaPO4 nanoparticles. These materials can find practical applications in biomedical areas for replacing conventional polymers.

In this work, three different Nd:YAG laser radiations (λ = 1064, 532, and 355 nm) were analyzed to obtain BN particles using pulsed laser ablation in liquids (PLALs). The effect of the laser energy in two reaction media (deionized water and acetone) during BN synthesis was analyzed through their structural, optical and photoluminescence properties. XRD patterns show the main reflections of h-BN and the existence of impurity phases that corresponds to c-BN or e-BN structures. The nanosecond laser energy is enough to transform h-BN hybridization from sp2 to sp3 and form new phases. The crystallite sizes (CS) of the h-BN particles grown in deionized water are between 66.4–68.8 nm for the three applied Nd:YAG harmonics. Similar CS were observed in colloidal BN particles fabricated in acetone (66.6–67.8 nm). The combination of the laser energy and reaction media modifies the BN particles morphology from platelets randomly oriented (D.W.) to melting-like structures (acetone). Size and melting degree are modified with the laser energy due to the capacity for plasma confinement of each reaction medium. Raman spectroscopy showed two vibrational modes dependent on the laser wavelength confirming that e-BN and c-BN phases coexist in the h-BN matrix. The formation of these secondary phases and morphological features are responsible of the differences in the optical properties. BN nanocrystals growth in D.W. like colloidal medium can act as UV shielding. Photoluminescence of BN structures (1064 nm) is observed in the range of 300–550 nm with a maximum emission at 3.26 eV. Due to the high structure disorder, the BN structures showed a broad emission with an intense luminescence that remain fairly constant after 48 h; resulting in blue luminescence character.

The data shown in this document provides all the experimental data that complement the article published in Carbohydrate Polymers entitled “Influence of operating conditions on Proton Conductivity of Nanocellulose films using two Agroindustrial Wastes: Sugarcane Bagasse and Pinewood Sawdust” [1]. The data of this paper are the result of a large series of experiments to optimize the extraction of cellulose nanocrystalline (CNC) from these two agro-industrial wastes: sugarcane Bagasse (SCB) and pinewood sawdust (PSW). The conditions of pretreatment (5 wt.% or 10 wt.% of NaOH) and hydrolysis temperature (60, 75 and 90°C) in an aqueous solution of 45 wt.% of H2SO4 were analyzed exhaustively. The data includes the characterization by Fourier transform infrared (FT-IR), Differential Scanning Calorimetry/Thermogravimetric Analysis (DSC/TGA), Dynamic Light Scattering (DLS), X-ray diffraction (XRD) patterns, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) micrographs with their corresponding SAED patterns and nanoindentation tests. Additionally, photographs during the isolation of cellulose nanocrystalline in dependence of the syntheses parameters. It is also included the data that complement the molecular dynamic simulation generated by GLYCAM carbohydrate builder based on the coordinates for alpha and beta cellulose considering a microfibril of 5, 10 and 20 glucosyl residues (degree of polymerization, DP). Overall data have not been previously published and are available contributing to a better understanding of the CNCs isolation through different pretreatment concentrations and temperatures of processing.

Cellulose nanocrystals (CNCs) were isolated from two-agroindustrial wastes: sugarcane bagasse (SCB) and pinewood sawdust (PWS), to analyze their chemical, structural, morphological, and proton conduction properties in dependence of the synthesis parameters. In both sources, the isolated CNCs correspond to the monoclinic phase of cellulose type I and II. For SCB, the smallest CNCs were isolated, in a range of 3–10 nm, with 5 wt.% of NaOH and 60 °C of acid hydrolysis. PWS displayed the smallest sizes at 75 °C and 10 wt.% NaOH (40–110 nm). Membrane characterization suggests that isolated CNCs, between 75 and 90 °C of acid hydrolysis and 10 wt.% NaOH from both SCB and PWS sources, displayed an important increase in the proton conductivity, 1.23(±0.61)×10−5 and 9.26 (±0.24)×10-5 S-m-1, respectively. Thus, with proper synthesis conditions, CNCs can be potentially used as based element to obtain other proton conductor materials to fabricate PEMs.

Structural, compositional, morphological and electrochemical characterization are important to determinate the influence of platinum in the methanol oxidation in alkaline media. These data and analysis support the research article catalytic performance of alloyed PtxPd1-x nanostructures supported on Vulcan XC-72R for the methanol oxidation in alkaline medium [1]. The data here presented included changes in the chemical composition, structure and microstructure. Also, complement data of cyclic voltammograms during activation in alkaline media as well as in presence of 1 M CH3OH to observe CO tolerance and Electrochemical Impedance Spectroscopy measurements at two different overpotentials (0.2 and 0.3 mV) on the onset potential for methanol electro-oxidation are published in this paper. The data can be used as a reference to determinate the effect of added different amounts of Pd to Pt/C catalysts, using an organometallic compounds method and octylamine as stabilizer. The data provided in this article have not been previously published and are available to enable critical or extended analyses.

Three organic compounds containing azole rings 1-benzyl-4-phenyl-1H-1,2,3-triazole (I1), 5-phenyl-3-propylisoxazole (I2), and 3,5-diphenylisoxazole (I3) were synthesized and characterized as corrosion inhibitors on galvanized steel and copper-nickel (Cu-Ni, 90/10) substrates. The three tested azole inhibitors acted as corrosion inhibitors on galvanized steel in the presence of real cooling water used as electrolyte. Electrochemical performance indicated that the presence of heteroatoms, such as N and O, with free pair electrons, the chain length, and the aromatic ring plays an important role in the capacity to inhibit corrosion of galvanized steel. 3,5-diphenylisoxazole (I3) has the best inhibition activity with jcorr of 2.04 × 10−7 (5 ppm), 7.57 × 10−8 (10 ppm), and 1.73 × 10−8 (20 ppm) A cm−2, followed by compounds I1 and I2. The synthesized compounds are comparable or even higher than the electrochemical performance of commercial inhibitor tolyltriazole (TTA, jcorr = 3.06 × 10−8 A cm−2). Conversely, for Cu-Ni (90/10) substrates, commercial TTA with 20 ppm displayed the lowest corrosion current densities (jcorr = 3.20 × 10−8 A cm−2) through a characteristic anodic pseudo-passivation; however, pits were observed after ~550 mVAg/AgCl. In contrast, the synthesized compounds tended to suppress anodic copper dissolution at positive potentials but, in the best case, displayed greater corrosion rates I3 (1.463 mils per year (MPY)), I2 (1.515 MPY), and I1 (0.677 MPY) in comparison with TTA (0.091 MPY). The low inhibition efficiency (IE) of synthesized compounds is correlated to the weak absorption on the copper surface.

In this work, hybrid composites were prepared using polyaniline (PANI) and electrochemically reduced graphene oxide (ERGO) by in situ polymerization. ERGO powders were obtained by a two-way route, Hummer’s method, and one-step potential (−2 V) followed by annealing process at 400°C (TERGO powders): different quantities of TERGO fine particles (10, 20, and 30 wt%) were added to the in situ PANI polymerization in order to produce the hybrid composites. The morphology and structure of the PANI/TERGO compounds were characterized by Raman spectroscopy, ultraviolet-visible spectroscopy (UV-Vis), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Thermal treatment of ERGO powders pointed out high-defect surfaces with a wrinkle-type morphology (ID/IG ratio~0.90). The emeraldine phase of PANI was obtained with a maximum value of 61%, which decreases with the amount of TERGO powders. It is also seen that composites displayed a combined morphology between PANI matrix and TERGO powders, confirming a physical interaction between both morphologies. The amount of TERGO particles into the polymeric matrix also modifies the sample microstructure from a semispherical shape to extend sheets, where PANI is sandwiched between TERGO layers. Electrical conductivity of composites slightly increases independent of the TERGO amount (30 S/m and 39 S/m) due to the rough TERGO surface that conditioned the homogeneous nucleation of a large amount of polymer (PANI) reducing the area to move the electrical charge.

Structural and microstructural characterization combined with vibrational, rotational modes are quite important to determinate reduction degree during synthesis of reduced graphene oxide. These data and analysis support the research article “Electrochemical alternative to obtain reduced graphene oxide by pulse potential: effect of synthesis parameters and study of corrosion properties” (López-Oyama et al., 2018). The data and analysis presented here included raw data for selected reduction potentials (VSCE) and different temperatures values (°C). Transmission electron microscopy (TEM) images of the exfoliated graphite are shown to corroborate the effect of the applied voltage to obtain electrochemically reduced graphene oxide (ERGO) on commercial 304L stainless steel (304L SS). The data provided in this article has not been previously published and are available to enable critical or extended analyses.

Two methods to form reduced graphene oxide (rGO) coatings are proposed as simple, rapid and reproducible alternatives to protect 304 L SS substrates. The first route combines traditional Hummers' modified method and pulse electrodeposition technique (−1.6 and −2 VSCE) whereas with the second one, reduction is obtained by applying the potentiostatic method (−1 to −4 VSCE) in a solution containing graphite + H2SO4. The electrochemical results show that ERGO coatings can properly protect metallic substrates only when they are obtained with an applied potential of −4 VSCE. To carry out this process, strong oxidants, extensive water amounts and long reaction times are avoided.

This work provides a comparative study on the corrosion protection efficiency of Ce, La films as well as Ce/La and La/Ce oxide bilayered coatings deposited onto AA7075 and AA6061 substrates by the radio frequency (RF) magnetron sputtering technique. The coating thickness ranged approximately from 12 to 835 nm, which changed with the deposition parameters and substrate composition. The relationship between microstructure, roughness and electrochemical performance is examined. The reactivity and crystallinity of rare earth (RE) films can be tailored by adjusting the sputtering parameters. Sputtered La films with thickness ca. 390 nm and average roughness of 66 nm showed the best corrosion protection properties in chloride medium as determined by potentiodynamic curves and electrochemical impedance spectroscopy (EIS). The method to obtain RE bilayered coatings, i.e., La/Ce or Ce/La as well as the substrate composition and applied power conditioned their inhibition properties. The RE bilayered coatings displayed better barrier properties than Ce films, which were poorer than those featured by La films.

Bismuth oxychloride (BiOCl) powders were synthesized via a hydro/solvothermal method from BiCl3. Synthesis were performed in the presence of different capping agents namely polyvinylpyrrolidone (PVP), ethylenediamine (C2H4(NH2)2) or dextrose (C6H12O6). The reaction media, nature of capping agent, weight or molar ratio Bi:capping agent and temperature play an important role in the formation of well-defined morphology of BiOCl powders, which varies from melt crystals to plate-like structures. The as-obtained BiOCl/capping agent systems were characterized by X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy and IR spectroscopy. Among the selected capping agents, the C2H4(NH2)2 promote a defined morphology of the BiOCl crystals being a potential soft template. BiOCl/C2H4(NH2)2 system synthesized in aqueous medium clearly illustrate the effect of the Bi:C2H4(NH2)2 ratio on the morphology of BiOCl powders. The photocatalytic activity of BiOCl/C2H4(NH2)2 (1:0.5 molar ratio or 0.5 equiv.) and TiO2:BiOCl composites were evaluated on the degradation of methylene blue (MB) under UV–Vis light irradiation and compared with commercial TiO2 (Degussa, P25). It was pointed out that BiOCl powders with well-defined rectangular plate-like morphology have a higher photocatalytic activity during MB photodegradation in comparison to TiO2:BiOCl composites and similar to commercial TiO2.

This work is focused on the structural, thermal and mechanical studies of direct polycondensation of poly (lactic acid) (PLA) modified with three different chain extenders (1,3-phenylene-bis-2-oxazoline, PBO; pyromellitic dianhydride, PMDA; and 1,1′-carbonyl bis caprolactam, CBC). Three concentrations of PBO, PMDA and CBC chain extenders (0.2, 0.5 and 1 wt%) were added during three stages (S): monomer dehydration (80 °C, S1), oligomer polycondensation (130 °C, S2) and melt polycondensation (160 °C, S3). FTIR, Raman and 1H-NMR spectroscopies revealed the presence of signals produced by interactions between OH and C=O end groups of PLA and reactive functional groups of chain extenders. It was found that the interaction with the PMDA chain extender decreased the PLA crystallinity. Furthermore, data from thermal analysis revealed that the interaction between PLA and chain extenders increased the chain mobility, which represented a decrease in its Tg. Enhanced mechanical properties, hardness, elastic modulus and indentation creep were observed with the addition of chain extenders, improving the performance with the addition of 1 wt% of PBO at S3, 1 wt% of PMDA at either S2 or S3 and 0.25 wt% of CBC at either S2 or S3. Additionally to the synthesis, the degradation was mainly influenced by the interaction more than by any specific stage of chain extender addition. Finally, the thermal and structural characterizations revealed that the PLA-PBO, PLA-PMDA and PLA-CBC systems were more resistant than PLA to UV light and humidity during the accelerated weathering test.
