Three 4-(trifluoromethoxy)phenyl-based polydithienylpyrroles (PTTPP, P(TTPP-co-DTC), and P(TTPP-co-DTP)) were synthesized electrochemically and their electrochromic behaviors were characterized. The introduction of electron withdrawing trifluoromethoxy unit in the side chain of polydithienylpyrroles (PSNS) decreases the HOMO and LUMO energy levels of PSNS. PTTPP film displays three various colors (grayish-yellow at 0 V, grayish-blue at 1.0 V, and bluish-violet at 1.4 V) from reduced to oxidized states. The optical contrast of PTTPP, P(TTPP-co-DTC), and P(TTPP-co-DTP) electrodes are 24.5% at 1050 nm, 49.0% at 916 nm, and 53.8% at 1302 nm, respectively. The highest η of the PTTPP electrode is 379.64 cm2 C−1 at 1050 nm. Three ECDs based on PTTPP, P(TTPP-co-DTC), or P(TTPP-co-DTP) as anodic film and PProDOT-Et2 as cathodic film were fabricated. PTTPP/PProDOT-Et2 ECD showed high transmittance change (35.7% at 588 nm) and high η (890.96 cm2·C−1 at 588 nm). P(TTPP-co-DTC)/PProDOT-Et2 and P(TTPP-co-DTP)/PProDOT-Et2 ECDs showed high transmittance change, rapid response time, adequate open circuit memory, and good electrochemical redox stability. Based on these findings, this work provides novel insights for appropriate design of high transmittance change and high efficient multi-colored electrochromic polymers.

This work explores the feasibility of reduction in sulfur content of waste oil (WO), by modified NaY zeolite adsorbent under ambient pressure. Parent NaY zeolite has been desilicated with alkaline solution and ion-exchanged in conjunction with Cu and Ni transition metals. Liquid phase ion-exchange employed for selectivity improvement and movement restriction of active metal ions through microwave irradiation and calcination. Modified Y zeolites were characterized, and their desulfurization efficiency over WO containing 4,160 ppm total sulfur have been analyzed. Results showed that Cu–NaY adsorbent removed 36.6% total sulfur and Ni–NaY modified zeolite adsorbed 37.1% of total sulfur after 40 min exposure at 75 °C. It was because of zeolite mesopores increased diffusion of lofty sulfur molecules into super-cages while metal loaded sites increased the selectivity of sulfur compounds in WO. Metal-exchanged mesoporous zeolites are ensuring adsorbent for the removal of sulfur-containing compounds from WO.

In this study, electrodes of titanium dioxide nanotube arrays (TNAs) were successfully synthesized by applying the anodic oxidation etching method, as well as the use of green synthetic technology to add reducing agents of tea or coffee to reduce metal palladium from palladium chloride. Synthesis of palladium modified TNAs (Pd/TNAs) was conducted by the microwave hydrothermal method after the metal palladium was reduced. In order to identify the surface structure, light absorption and elemental composition, TNAs and Pd/TNAs were characterized by X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). Furthermore, to test the photocurrent density, electron resistance, and hydroxyl radicals by I-t plot, electrochemistry impedance spectroscopy (EIS), and electron paramagnetic resonance (EPR) were investigated. The photocurrent (4.0 mA/cm2) of Pd/TNAs-C (using coffee as the reducing agent) at +1.0 V (vs. Ag/AgCl) was higher than that of the pure TNAs (1.5 mA/cm2), illustrating that Pd/TNAs-C can effectively separate photogenerated electrons and holes. Pd/TNAs is a favorable material as a photoanode for the photoelectrochemical (PEC) removal of organic pollutants in wastewater.

With the advancement of technology and industrial growth, environmental pollution has become the major phenomenon that hinder the environmental adjoining with the volume of wastes that has been discarded without any proper treatment. In particular, industrial sector consumes a maximum amount of water which results in generating of large quantity of solid waste-sludge. However, with the progression of environmental awareness, the treatment of sludge recycling and reuse has been carried out considerably. Subsequently, after drying, sorting, granulating, sintering and other procedures, it is re-created into various types of aggregates and used for making biochar and other purposes. Therefore, in this study, the waste rice straw and coconut shell were mixed with the sludge and the biomass was pressed to form a non-loose granular shape, subjected to low-temperature of 300–400 °C co-firing carbonization technique for 30–60 min to prepare a solid refuse-derived fuel (RDF-5). The higher the addition ratio of the raw material (rice straw or coconut shell), the more superior is the effect of the mixture. The optimum carbon content is then mixed with inorganic sludge (IS) and organic sludge (OS) and the calorific value obtained was about 2852 Cal/g and 2840 Cal/g.

In this study, biodiesel synthesis from waste cooking oil (WCO) using waste oyster shells derived catalyst (CaO-based catalyst) as a sustainable based heterogeneous catalyst under a microwave heating system technology was investigated. The CaO-based catalysts were characterized by Fourier Transform-Infrared (FTIR), X-ray diffraction (XRD), Electronic Data System (EDS) and Brunauer-Emmett-Teller (BET) measurements. Under optimized conditions, this study has produced tentative results with considerable performances in relations to biodiesel synthesis as follows: (1) the intensification in relation to reaction time from 120 to 180 min has significantly increases the biodiesel yield, which declines with a more intensification to 120 min; (2) the synthesis of biodiesel in this study has proved to increase with an upsurge reaction of power; (3) whereas 180 min reaction time with 800 W microwave power, a methanol-to-oil molar ration of 9:1, a reaction temperature of 65 °C; and 6 wt% catalyst concentration was revealed to be optimal and perfect reaction conditions for this present research work. The highest biodiesel yield was recorded at 87.3% in this study. Whereas the activation energy (Ea) for the catalyzed transesterification reaction was found to be 9.56 kJ/mol. In a nutshell, waste oyster shells were recycled as a sustainable base heterogeneous catalyst to synthesize new biodiesel from WCO, which can be used in diesel engines to address air pollution, especially pollutant emissions from diesel automobiles.

With the depletion of oil and natural reserves, gasoline-bioethanol blend has been considered as one of the finest alternative fuels. However, the fuel blend can also lead to higher fuel consumption as a result of adverse influence. Hydrogen as fuel additive contains many benefits in comparison to other petroleum since it promotes oxidation and decreases pollutant compounds during the combustion process. Therefore, this study aims to investigate the effect of pollutant emissions, fuel consumption and well-to-wheel GHG emissions from a vehicle operating with gasoline-bioethanol blend (E3, E6 and E10), and hydrogen produced (0.6 LPM) on-board under cold start and FTP-75 transient cycle. The results show that hydrogen addition fueled with gasoline-bioethanol blend (E6 and E10) improves diffusion speed and homogeneous mixing, benefiting the complete combustion of fuel-air mixture. The significant reduction of CO, HC and NOx could be found under cold start and FTP-75. The reduction of 0.096, 1.19 and 1.10% on fuel consumption were obtained for E3, E6 and E10 with hydrogen addition. From the environmental point of view, the E10 with and without hydrogen addition appears to be agreeable since the outcome of well-to-wheel GHG emissions account for significant reduction in comparison with the base fuel (G0).

Innovative approaches for recovery indium from waste liquid crystal displays (LCDs) has been continuously demanded with increasing concerns over its threat to human health and environment. In this work, we recycled indium from waste LCD panels based on acid leaching procedure (HCl, HClO4 and H3PO4) under microwave and ultrasound-assisted heating system. To optimize the leaching protocol, the method of full factorial experimental design was adopted to explore the influence of different parameters (microwave power, reaction time, acid concentration, and liquid to solid ratio). Results revealed that 100% leaching yield could be achieved as microwave power of 650 W, HCl concentration of 4 M, and liquid: solid ration of 2 within only 142 s. Overall, the leaching effect can be ranked as HCl > H3PO4 > HClO4. To further recovery indium from the acid solution after the microwave leaching by electrorefining, different electrolysis times (2 h, 4 h, 6 h, 8 h, 10 h), voltages (10 V, 15 V, 20 V) and currents (0.1 A, 0.3 A, 0.5 A, 0.7 A, 0.9 A, 1 A, 3 A, 4 A, 5 A) were investigated, the optimal indium recovery yield was accomplished by 93.41% with 1 A and 10 V for 10 h. The metal indium precipitate metalized at the cathode after electrolysis was found to be 99.14% for the purity. In addition, pareto chart analysis of standardized effect and regression mode were employed to testify the optimal leaching condition. This work demonstrates an effective and facile way to recovery indium from wasted LCDs with desirable leaching yield than conventional heating approach.

Advancement in the field of biomass and bioenergy has pulled in researchers to produce biofuels derived from naturally accessible feedstock by adopting diverse innovative approaches in biomass pretreatment. In this study, pyrolysis of micro algae with downstream processing of biomass from the resonator cavity under atmospheric pressure was conducted and hydrogen production produced under different microwave power was analyzed. With the increase in microwave power, the hydrogen gas yield accounted to be as twice as that at lower power, where the concentration of produced hydrogen accounts for about 30.80%, 33.20%, and 37.58% at microwave power levels of 800, 900 and 1000W. It was also observed that no methane was produced in this study since most of the methane produced from microwave plasma conversion has reacted with CO2 and produced CO and H2, hence dropped in the concentration of CO2 with decline in power intensity.

Spent lithium ion batteries (LIBs) can be of great environmental concern because of the generation of heavy metal pollution in such wastes in huge quantities, mainly from the fast-growing mobile phone market. In this research, acidic leaching coupled with microwave and ultrasonic heating is integrated with oxidative precipitation and solvent extraction to reclaim and purify the metals in the cathode material of batteries. To optimize the leaching process, the effects of the concentrations of acids and reductant (H2O2), solid loading, and temperature, as well as heating with microwaves and ultrasound, on Co, Li, Mn, Ni, Cu, and Al dissolution are systematically tested. KMnO4 is first applied to remove Mn as MnO2 precipitate from the leachate, and most of the Li can be selectively collected in the aqueous phase by solvent extraction using di-(2-ethylhexyl) phosphoric acid. At the end of the process, the majority of Co and minor amounts of Ni, Cu and Al are reversely extracted using HCl. An effective purification process is proposed to obtain more than 90% of the valuable metals in each of the leaching, precipitation and extraction steps.

This study investigates the PM2.5 emission and analyses the PAHs content in PM2.5 emitted from gasoline-fueled vehicles. Outflow from the vehicles appear to be the ultimate source of PAHs in metro urban communities since the emission from gasoline vehicle increases the wellbeing hazard due to contiguity of exposure to gasoline exhaust. In this study, fifteen vehicles were randomly taken for sampling, where sixteen priority PAHs concentration were investigated. The study was performed on the vehicles with different Euro standard emission by taking into consideration the European legislative levels for vehicles on the toxic gaseous emission. Among all the PAHs outflow components of PM2.5 radiated in the exhaust of gasoline engines, the average concentration of total PAHs discharged was 0.377ng/L-fuel, while the total BaPeq concentration was 0.00993ng/L-fuel.

Efficient energy usage and energy saving is one of the nowadays necessity for all scientists of IC engine. This is because of the current environmental challenges that have tremendously increased concerning air pollution, particularly pollutant emissions from vehicles. Yet, industries and governments alike have disregarded this phenomenon which has been considerably contributing to climate change. It is against this background that, the research works carried out in this present study is predominantly focusing on improving energy efficiency and reducing emission levels from diesel engines. This can be achieved with the help of atmospheric-plasma system which can offer a noble solution to the above-mentioned challenges due to its potential to improve combustion efficiency which leads to energy efficiency, while reducing emission levels from diesel engines. In this study, the performance and emissions of a diesel generator supplemented with an atmospheric-plasma system was examined. The diesel engine was used to examine the effects of fuel composition, or brake specific fuel consumption, thermal efficiency and pollutant emissions at different plasma system voltages. To this end, we equally examined the effects of atmospheric-plasma system on energy efficiency improvement and emissions reduction from diesel engine as the main purpose of this study. We do so by testing the diesel-fueled engine generator under the atmospheric-plasma system. The tests were carried out at a constant state condition with the engine running at 2200 rpm with torque and power outputs of 10.4 Nm (75% of the max load) and 2.1 kW, separately, for the tested fuels and this was used to increase the output voltage of the plasma system during this study. The plasma system ionized the intake air and improved the formation of free radicals upon combustion. During this study, the output voltage of the plasma was set within the range of 0–7 kV. The experimental results have indicated that formaldehyde, acetaldehyde and acrolein account for more than 75% of total carbonyl compounds emissions. Simultaneously, it was also observed from the results that higher plasma system voltage reduces pollutants emissions levels. Hence, such reduction is predominantly evident for nitrogen oxides, particulate matters and carbon monoxide. However, the marginal improvements of engine performance and emissions reduction become insignificant when the plasma system voltage reaches 6 kV. On the other hand, increasing the amount of plasma system voltages in diesel engine continues to significantly reduce pollutant emissions.

Notwithstanding its significance, there are noteworthy challenges in quantitative assessment of its contribution to the concentrations of airborne. This study reports on the characterization and quantification of PM2.5 emissions and PAHs concentration in PM2.5 from the exhausts of on-road diesel vehicles with various accumulated mileages in Kaohsiung City, Taiwan. Urban areas could be a subject matter not just in connection to deprived air quality, but similarly to pollution of other significant environmental media by air contaminants. To that end, our study intends to estimate the PM2.5 emissions from diesel vehicles using diesel fuels and to analyze the PM2.5 emissions and PAHs concentration in PM2.5. In this study, particulate matters (PM2.5) were characterized and quantified from a place impacted by diesel vehicles fueled with diesel in Kaohsiung City, Taiwan. The tested diesel vehicles with various accumulated mileages overs the model year comprising of the vehicles registered from 1984 to 2012 from different manufacturers (or brands) ranging from 8733 to 965,026 km (average 445,433 km) accumulative mileages. Exhaust constituents include CO, NOx, PM2.5 and particle phase PAHs. The concentrations of twenty-one (21) priority polycyclic aromatic hydrocarbons (PAHs) were studied in the samples by their relationship with atmospheric PM2.5. However, in relations to cumulative mileages, lower cumulative mileage (mileage <20,000 km) has the lowest CO and NOx emission factors. The mileage ranged from 20,001 to 30,000 km had an increased CO and NOx emission factors, respectively. Interestingly, with the increased high number of mileages ranged from 30,001 to 50,000 km, CO and NOx emission factor was observed to be declining, respectively. This could be attributed to the technological changes on new diesel vehicle models. But nonetheless, the trend of CO emission factor was found to be higher with an increasing of cumulative mileages as compared to the mileage that reached lower than 30,000 km.

This research investigates the mileage and the health risk assessment of aerosol carcinogenicity and mutagenicity emitted by ten in-use motorcycles. The total p-PAHs emission factor of ten in-use motorcycles are 676.3 µg km-1 with average of 67.6 ± 13.6 µg km-1. Naphthalene (Nap) shows the largest emission factors, followed by phenanthrene (PA) and fluoranthen (FL). The mileage present high correlation coefficient (Rsp = 0.681) with CO. CO is associated with cumulative mileage leading to bad combustion efficiency, which caused low to high relationship for total p-PAHs (Rsp = 0.388), PM2.5 (Rsp = 0.680) and NOx (Rsp = 0.799). Both PM2.5 and total p-PAHs are generally generated via incomplete combustion and the results expressed the moderate to high correlation (Rsp = 0.578, 0.898) with NOx. Taking into consideration of high-mileage motorcycles (30,001-50,000 km), the toxic equivalent of carcinogenicity and mutagenicity exhaust are about 4.67, 1.99 and 3.89, 2.0 times higher than low (10,001-20,000 km) and middle (20,001-30,000 km) cumulative mileages, respectively. Therefore, in the conclusion of our study in compared with that of other research directed the fact that lower carcinogenicity and mutagenicity emission factor were found at lower cumulative mileages motorcycles however, the impact increases with the high cumulative mileage motorcycles.

This work evaluated the effectiveness of rice straw pretreatment using a TiO2/UV system in the presence of oxidants. The effects of TiO2 concentrations, pH and photocatalysis time were investigated. Inorganic oxidants including H2O2, K2S2O8, and KIO4 were added to further enhance the effect on enzymatic hydrolysis of rice straw. The TiO2/UV/ H2O2 pretreatment showed a higher amount of released reducing sugar (8.88 ± 0.10 mg/mL, compared to 5.47 ± 0.03 mg/mL in untreated sample). Composition analyses of rice straw after the TiO2/UV/H2O2 pretreatment showed partial lignin and hemicellulose removal. Moreover, structural features of untreated and pretreated rice straw were analyzed through FE-SEM, FT-IR, and XRD. This work suggests that H2O2 is an efficient addition for photocatalysis pretreatment of rice straw.

This paper intends to explore the most affordable and environmentally friendly method for the synthesis of biodiesel. Substitute fuel is presently a significant topic all over the world, attributable to the efforts of reducing global warming, which is the result arising from the combustion of petroleum or petrol diesel fuel. Due to its advantages of being renewable and environmentally friendly, biodiesel production has the potential to become the major substitute of petrol diesel fuel. Biodiesel is non-toxic, biodegradable, is produced from renewable sources, and contributes a small amount of greenhouse gas (e.g., CO2 and SO2) emissions to the atmosphere. Research has established that one of the key obstacles to the commercialization of biodiesel is the high price of biodiesel production due to the shortage of suitable raw materials. However, waste-cooking-oil (WCO) is one of the most cost-effective sources of biodiesel synthesis, and can practically minimize the raw material cost. The research was carried out to produce biodiesel from waste cooking oil in order to reduce the cost, waste, and pollution associated with biodiesel production. The application of a microwave heating system towards enhancing the production of biodiesel from waste cooking oil has been given little consideration in the preceding research, particularly with the application of eggshell as a heterogeneous catalyst. However, the tentative results in this study show significant performance in terms of biodiesel production, as follows: (1) the increasing of the reaction time from 120 to 165 min considerably increased the biodiesel production, which declined with a further rise to 210 min; (2) the results of this study reveal that a methanol-to-oil molar ratio of nine is appropriate and can be used for the best production of biodiesel; (3) the production of biodiesel in this study demonstrated a significant increase in response to the further increasing of power; (4) a 120 min response time, a ratio of 9:1 methanol-to-oil molar fraction, 65 °C temperature; (5) and 5 wt % catalyst were found to be the most ideal reaction conditions during this study. In summary, recycled eggshell was re-used as a suitable catalyst to produce new biodiesel from waste cooking oil, applicable to diesel engines.

A carbazole-based polymer (poly(tris(4-carbazoyl-9-ylphenyl)amine) (PtCz)) is electrosynthesized on an indium tin oxide (ITO) electrode. PtCz film displays light yellow at 0.0 V, earthy yellow at 1.3 V, grey at 1.5 V, and dark grey at 1.8 V in 0.2 M LiClO₄/ACN/DCM (ACN/DCM = 1:3, by volume) solution. The ΔT and coloration efficiency (η) of PtCz film are 30.5% and 54.8 cm²∙C-1, respectively, in a solution state. Three dual-type electrochromic devices (ECDs) are fabricated using the PtCz as the anodic layer, poly(3,4-ethylenedioxythiophene) (PEDOT), poly(3,3-dimethyl-3,4-dihydro-thieno[3,4-b][1,4]dioxepine) (PProDOT-Me₂), and poly(3,4-(2,2-diethylpropylenedioxy)thiophene) (PProDOT-Et₂) as the cathodic layers. PtCz/PProDOT-Me₂ ECD shows high ΔTmax (36%), high ηmax (343.4 cm²·C-1), and fast switching speed (0.2 s) at 572 nm. In addition, PtCz/PEDOT, PtCz/PProDOT-Me₂, and PtCz/PProDOT-Et₂ ECDs show satisfactory open circuit memory and long-term stability.

The immunotoxicity of engine exhausts is of high concern to human health due to the increasing prevalence of immune-related diseases. However, the evaluation of immunotoxicity of engine exhausts is currently based on expensive and time-consuming experiments. It is desirable to develop efficient methods for immunotoxicity assessment. To accelerate the development of safe alternative fuels, this study proposed a computational method for identifying informative features for predicting proinflammatory potentials of engine exhausts. A principal component regression (PCR) algorithm was applied to develop prediction models. The informative features were identified by a sequential backward feature elimination (SBFE) algorithm. A total of 19 informative chemical and biological features were successfully identified by SBFE algorithm. The informative features were utilized to develop a computational method named FS-CBM for predicting proinflammatory potentials of engine exhausts. FS-CBM model achieved a high performance with correlation coefficient values of 0.997 and 0.943 obtained from training and independent test sets, respectively. The FS-CBM model was developed for predicting proinflammatory potentials of engine exhausts with a large improvement on prediction performance compared with our previous CBM model. The proposed method could be further applied to construct models for bioactivities of mixtures.
