In this review, we present the phase behaviour of liquid crystals (LCs) confined to Controlled-Pore Glasses (CPG) of various pore sizes. We consider either non-treated or silane-treated CPG pore surfaces, which impose parallel and homeotropic alignment to n-cyanobiphenyl (n-CB) LCs, respectively. The resulting nematic or smectic ordering depends on the characteristic void radii R and is well described in terms of the Landau-de Gennes free energy. Experimental data for different n-CB LCs, 5CB, 8CB, and 12CB, demonstrate phase transitions in orientation and translational degrees of freedom. In the bulk, 5CB and 8CB exhibit on cooling from the isotropic (I) phase the 1st order isotropic-nematic (I−N) phase transitions. In addition, 8CB also exhibits on further cooling a 2nd order nematic-smectic A (N−SmA) phase transition. 12CB, on the other hand, only has a 1st order isotropic-smectic A (I−SmA) phase transition. The bulk LCs exhibit a variety of different phase structures. When LCs are confined to porous media, their phase structures can be modified and even glass transition is possible. For LCs confined to CPG, the phase transition temperatures are shifted, depending on the pore size and the pore surface treatment. The Landau-de Gennes model predicts that the present phase transition shifts display inversely linear and inversely quadratic contributions in terms of the characteristic pore sizes. Furthermore, for strong enough confinement the phase transitions are replaced by gradual evolution of LCs order. These predictions are in line with nuclear magnetic resonance, small- angle X-ray scattering, and high-resolution calorimetry experimental observations.

Space exploration has recently been growing at an increasing pace and has caused a significant burden to the environment, in particular, during the launch of rockets, when a large amount of fuel is burned and the exhaust gases are released in the air. For this case study, we selected the SpaceX Falcon Heavy reusable heavy-lift launch vehicle, which is one of the most promising rockets for the low-cost lifting of heavy payloads into orbit and beyond. We evaluated several strategies for optimisation of fuel consumption and for minimisation of environmental impact during launch through the atmosphere for the case of its first launch on February 6, 2018, when the rocket carried a red Tesla Roadster with a “Starman” in the direction toward Mars. In addition to the flight plan and Newtonian equations of motion, we have taken into account the thermodynamic properties of the rocket engines. Results are similar but slightly different if one minimises the total fuel consumption for the desired flight plan or if one minimises the environmental pollution during the initial stage of the launch through the atmosphere. The same methodology can be extended for launches in other directions including the Earth orbit and the Moon.

Since graphene has been discovered, two-dimensional nanomaterials have attracted attention due to their promising tunable electronic properties. The possibility of tailoring electrical conductivity at the atomic level allows creating new prospective 2D structures for energy harvesting and sensing-related applications. In this respect, one of the most successful way to manipulate the physical properties of the aforementioned materials is related to the surface modification techniques employing plasma. Moreover, plasma-gaseous chemical treatment can provide a controlled change in the bandgap, increase sensitivity and significantly improve the structural stability of material to the environment as well. This review deals with recent advances in the modification of 2D carbon nanostructures for novel ‘edge’ electronics using plasma technology and processes.

Organic crystals with second-order optical nonlinearity feature very high and ultra-fast optical nonlinearities and are therefore attractive for various photonics applications. During the last decade, they have been found particularly attractive for terahertz (THz) photonics. This is mainly due to the very intense and ultra-broadband THz-wave generation possible with these crystals. We review recent progress and challenges in the development of organic crystalline materials for THz-wave generation and detection applications. We discuss their structure, intrinsic properties, and advantages compared to inorganic alternatives. The characteristic properties of the most widely employed organic crystals at present, such as DAST, DSTMS, OH1, HMQ-TMS, and BNA are analyzed and compared. We summarize the most important principles for THz-wave generation and detection, as well as organic THz-system configurations based on either difference-frequency generation or optical rectification. In addition, we give state-of-the-art examples of very intense and ultra-broadband THz systems that rely on organic crystals. Finally, we present some recent breakthrough demonstrations in nonlinear THz photonics enabled by very intense organic crystalline THz sources, as well as examples of THz spectroscopy and THz imaging using organic crystals as THz sources for various scientific and technological applications.

There is a need for fast and reliable quality and authenticity control tools of pharmaceutical ingredients. Among others, hormone containing drugs and foods are subject to scrutiny. In this study, terahertz (THz) spectroscopy and THz imaging are applied for the first time to analyze melatonin and its pharmaceutical product Circadin. Melatonin is a hormone found naturally in the human body, which is responsible for the regulation of sleep-wake cycles. In the THz frequency region between 1.5 THz and 4.5 THz, characteristic melatonin spectral features at 3.21 THz, and a weaker one at 4.20 THz, are observed allowing for a quantitative analysis within the final products. Spectroscopic THz imaging of different concentrations of Circadin and melatonin as an active pharmaceutical ingredient in prepared pellets is also performed, which permits spatial recognition of these different substances. These results indicate that THz spectroscopy and imaging can be an indispensable tool, complementing Raman and Fourier transform infrared spectroscopies, in order to provide quality control of dietary supplements and other pharmaceutical products.

In different industrial applications, several strictly defined parameters of calcium-based microfillers such as average particle size, particle size distribution, morphology, specific surface area, polymorphism and chemical purity, play a key role in the determination of its usefulness and effectiveness. Therefore, an analytical tool is required for rapid and non-destructive characterization of calcium-based microfillers during the synthesis process or before its use in a further manufacturing process. Since spectroscopic techniques are preferred over microscopy and thermogravimetry, particularly due to its non-destructive nature and short analysis time, we applied terahertz (THz) spectroscopy to analyse calcite microfillers concentration in polymer matrix, its granulation and chemical treatment. Based on the analysis of peak absorbance amplitude, peak frequency position, and the appearance of additional spectral features, quantitative and qualitative analysis was successfully achieved. In addition, THz imaging was also applied for both quantitative and qualitative analysis of calcium-based microfillers. By using spatial distribution map, the inhomogeneity in concentration of calcium carbonate in polymer matrix was characterized. Moreover, by THz spectroscopy and imaging different calcium compounds were detected in binary mixtures. Finally, we demonstrated that the applied spectroscopic technique offers valuable results and can be, in combination with other spectroscopic and microscopic techniques, converted to a powerful rapid analytical tool.

Several pharmaceutical drugs, such as alprazolam, ibuprofen, acetaminophen, activated carbon and others, and caffeine-containing foods were tested using terahertz (THz) time domain spectroscopy in the range from 0.3 to 2 THz. The dry powder of pharmaceutical drugs was mixed with HDPE and pressed into the pellets using hydraulic press. The coffee grounds were also pressed into the pellets after ball-milling and mixing with HDPE. The caffeine containing liquid foods were dried out on the paper strips of various stacking. Experiments allow one to determine characteristic spectral signatures of the investigated substances within THz range caused by active pharmaceutical ingredients, like in the case of caffeine, as well as supporting pharmaceutical ingredients. Spectroscopic THz imaging approach is considered as a possible option to identify packaged pharmaceutical drugs. The caffeine spectral features in the tested caffeine containing foods are difficult to observed due to the low caffeine concentration and complex caffeine chemical surrounding. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

We study the impact of anisotropic nanoparticles (NPs) on the nematic liquid crystal (LC) order. Within a mesoscopic Flory–Huggins-type approach we have estimated regimes where LC–NP mixtures are essentially homogenous. Using a lattice Lebwohl–Lasher type approach we have also studied the impact of anisotropic NPs on LC ordering. We analysed the cases where the orientations of NPs are either frozen-in or could be varied, to which we refer as random field mixtures and annealed mixtures, respectively. In the latter case we have demonstrated the existence of qualitatively different regimes. In particular, we determined the concentration regime, where LC configurations resembling a transparent nematic phase could be observed. Such domain patterns are stabilised by NPs hindering the annihilation of topological defects in LC order.

Terahertz time-domain spectroscopy and imaging is used to study the effects of various hiding techniques of spectral features of drug and explosive simulants in combination with different paper and textile barriers. Results show that rapid detection and identification of concealed simulants is possible in the frequency range from 1.5 to 4.0 THz by using an organic-crystal-based terahertz time-domain system and the spectral peak analysis method.

Structural analysis of polymer foams for insulation enables manufacturers and research facilities to optimise their products and production processes for applications such as building construction. Therefore, two- and three-dimensional investigation of the macro- and microstructure of these materials is important in order to characterize their physical and mechanical properties. In this paper, we present terahertz time-domain spectroscopy and pulsed imaging method to analyse the macroscopic structure of foamed polymers including analysis of voids, inclusions and bead distribution. By measuring the difference between the terahertz waveforms and by calculating the spectroscopic constants we analyse certain material characteristics such as foam density and infrared radiation absorption. Furthermore, we demonstrate that terahertz techniques have several advantages over other technologies, in particular as a non-ionizing alternative to X-ray tomography, and a complementary imaging method to optical or electron microscopy enabling chemical and structural characterization of foamed polymers.

It is demonstrated that interactions between nanoparticles and topological defects induce a twist-grain boundary phase in a chiral liquid crystal. The occurrence of this phase, the analogue of the Shubnikov phase in type-II superconductors, is driven by direct interactions between surface-functionalized CdSe quantum dots and screw dislocations. It is shown that, within an adaptive-defect-core-targeting mechanism, nanoparticles of appropriate size and functionalization adapt to qualitatively different cores of topological defects such as disclination lines and screw dislocations. This mechanism enables the effective reduction of the energetically costly, singular defect core volume, while the surrounding phase ordering remains relatively weakly affected. The findings suggest new pathways towards the controlled assembly of superstructures in diverse, symmetry-broken, condensed-matter systems, ranging from nanoparticle-decorated liquid crystals to superconductors.

The two-dimensional presentation of the three-dimensional nematic liquid crystal structure can be visualized in various ways: by oriented rotational ellipsoids, bricks, cylinders, or sticks, representing either individual molecules or nematic director field. Here, we give a different approach: the three axes of Cartesian coordinate system are assigned with three colors (red for x-axis, green for y-axis and blue for z-axis). We use the proportional mixing of these colors for various directions of the nematic director. Using this technique, different structures of nematic liquid crystals can be visualized clearly, particularly when combined with representation of nematic director field with sticks.

Sulfur dioxide (SO2) and nitrogen dioxide (NO2) emissions generated at coal burning power plants and from transport are a leading cause of acid deposition and chemical smog in many parts of the world. Sulfur dioxide emitted by thermal power plants and from transport in Kosovo is transported via prevailing winds to other locations. Through its journey, this SO2 gas undergoes a series of chemical reactions that ultimately transform it into sulfuric acid (H2SO4) which is deposited as acid rain. As a consequence of NO2 emissions from electricity production and transport in Kosovo the ozone (O3) is formed as photochemical smog due to sunlight, which triggers the breakdown of NO2. We modeled the impact of SO2 and NO2 emissions from energy system and transport in Kosovo on acid deposition and chemical smog locally. In model we consider the role of SO2 and NO2 pollution control technologies on mitigating these impacts.

Climate change is influenced not only by the emissions of greenhouse gases, but also by the emissions of air pollutants which influence each other through complex interactions in the atmosphere. Reducing emissions could be one way to react and prevent negative impacts from climate change. Because these reductions must take place in the face of economic growth, there is a disagreement about the concrete time and the rate of the pollution emission reduction (PER). By modelling of short and long term emission reduction scenarios, the authors analyse responding of: pollution, population, non-renewable resources and industrial output of post-2015, that could establish a foundation for undertaking actions to mitigate climate change, taking into account both their environmental and economic consequences. In long term scenarios, the values of the factors discussed depend mainly on the year when the pollution reduction is achieved, and very little on the rate of emission reduction. From the analysis of the results straightforwardly follows that in any climate stabilisation strategy, the early action in reducing emission is a more important element than the rate of its decrease.
