Abstract In this work the chemical bath deposition (CBD) method was used to synthesize Cadmium sulphide (CdS) thin films on glass, silicon (Si), and porous silicon (PSi) substrates. The PSi substrates were prepared by an electrochemical etching method using different current densities at constant etching time of 5 minutes. The CdS thin films were characterized using the X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), optical transmittance spectroscopy in the Uv visible range, and electrical characterization (I–V characteristics). The obtained results demonstrated that the morphology of the deposited materials was influenced by the… More >

Abstract This study focuses on the development of zinc oxide (ZnO)/zinc sulfide (ZnS) core-shell structures on flexible polyethylene terephthalate (PET) substrates for enhanced light sensing. PET offers high elasticity, optical transparency, and chemical resistance, making it ideal for wearable optoelectronics. By optimizing the vulcanization process, a uniform ZnS shell is formed on the exposed regions of ZnO nanorods (NRs), significantly enhancing ZnO-based sensor’s sensitivity to visible light, especially red light (peak wavelength at 630 nm). Structural and spectral analyses confirm the successful formation of the ZnO/ZnS heterostructure, improved charge separation, and broadened light response. To improve More >

Abstract This paper investigates the possibility of growing solid solutions of the composition (Ge₂)_1−x−y(GaAs_1−δBi_δ)_x(ZnSe)_y on silicon substrates using a germanium (Ge) buffer layer. The optimal conditions for obtaining a structurally high-quality epitaxial layer have been determined. In the study, the solid solution was obtained by liquid-phase epitaxy from a bismuth-containing melt solution. Epitaxial growth was carried out in a palladiumpurified hydrogen atmosphere at a cooling rate of 1 ÷ 1.5°C/min in the temperature range 750 ÷ 650°C. Experimental data showed that the growth of the epitaxial film significantly depends on the size of the gap between the… More >

Abstract Natural fibers, as a typical renewable and biodegradable material, have shown great potential for many applications (e.g., catalysis, hydrogel, biomedicine) in recent years. Recently, the growing importance of natural fibers in these photo-driven applications is reflected by the increasing number of publications. The utilization of renewable materials in photo-driven applications not only contributes to mitigating the energy crisis but also facilitates the transition of society toward a low-carbon economy, thus enabling harmonious coexistence between humans and the environment within the context of sustainable development. This paper provides an overview of the recent advances of natural… More > Graphic Abstract

Abstract Soybean is an important legume food crop, and its seeds are rich in nutrients, providing humans and animals with edible oil and protein feed. However, soybean is sensitive to water requirements, and drought is an important factor limiting soybean yield and quality. This study used Heinong 84 (drought resistant variety) and Hefeng 46 (intermediate variety) as tested varieties planted in chernozem, albic, and black soils. The effects of drought stress on the activities of key enzymes in carbon metabolism and photosynthetic characteristics of soybean were studied during the flowering stage, most sensitive to water.

Abstract The emissions of two greenhouse gases (GHG), carbon dioxide (CO2) and nitrous oxide (N2O), from six substrates with different carbonaceous content were compared in short and long-term incubation experiments. Three natural soils and three artificial chars were mixed with carbon (C) poor soil (Cambisol) to simulate real conditions after application of char to farmland. The natural soils were a Cambisol, an Anthrosol and a Histosol with C contents of 1.3%, 4.4% and 13.2%, respectively. The three chars produced through thermal conversion of wood chips by hydrothermal carbonisation (HTC), fluidized bed gasification and pyrolysis had C… More >

Abstract Four different ratios of river sand, ceramic pellets, vermiculite and perlite (1:1), and field soil were selected as the substrates in this experiment, and four gradient levels of root waterlogging, half waterlogging, full waterlogging and normal were set to investigate the effects of different gradients of waterlogging stress on the root morphology of Taxus chinensis var. mairei seedlings under different substrates. In this study, the root anatomical structure of Taxus chinensis var. mairei under different waterlogging stress was observed by the paraffin section method. The roots of T. chinensis var. mairei were diarch, with no pith and resin canals. There… More >

Abstract An alternative method for improving the production of habanero chili is the tissue culture technique; however, the gelling agent, the high salt and sucrose concentrations used in the culture media raise production costs and limit the adaptation of the regenerated plants to greenhouse or field conditions. In this study, the effect of the substrates perlite-coconut fiber, coconut fiber-volcanic rock, vermiculite-perlite, and perlite-volcanic rock in conjunction with various culture media in in vitro plant regeneration from embryos was evaluated. The differentiation of adventitious shoots on substrates was scarcely observed or non-existent. Inducing the formation of shoots on… More >

Abstract Cellulose-based materials are one of the most widely used materials provided by nature to mankind. In particular, cotton fi bers have been used for millennia to produce clothing items. This wide usage stems from the inherent properties of cotton fabrics such as hydrophilicity and permeability to water vapor. However, increasingly sophisticated uses for cotton-based clothing (e.g., technical textiles) demand specifi c properties such as hydrophobicity and oleophobicity for repellent functions. The current surface treatments used to attain these functionalities are based on thermally initiated polymerization reactions, using water-based formulations. Thus, the current technologies are energy-… More >
