Abstract The development of the bioplastics industry addresses critical issues such as environmental pollution and food safety concerns. However, the industrialization of bioplastics remains underdeveloped due to challenges such as high production costs and suboptimal material characteristics. To enhance these characteristics, this study investigates bioplastics reinforced with Nanocrystalline Cellulose (NCC) derived from Oil Palm Empty Fruit Bunches (OPEFB), incorporating dispersing agents. The research employs a Central Composite Design from the Response Surface Methodology (RSM) with two factors: the type of dispersing agent (KCl and NaCl) and the NCC concentration from OPEFB (1%–5%), along with the dispersing… More >

Abstract In present work, Cu₂BaSnS₄(CBTS) nanoparticles are reported solvothermally synthesized. The formation of single-phase trigonal structure of CBTS nanoparticles is confirmed by XRD and Raman spectroscopic analysis. SEM studies reveal that CBTS exhibits flower shaped structure self-assembling by nanosheets with uniform average thickness 30nm. CBTS materials show abroad absorption in the complete visible range, providing a band-gap value of 1.58eV, indicating potential applications in photocvoltaics. The excellent MB degradation efficiency of 93% under visible light within 100min is achieved, suggesting CBTS is a potential material for effective solar light photocatalytic application. Meanwhile, electrical properties are measured up More >

Abstract In this study, high-crystallinity zinc sulfide (ZnS) at the nanoscale was synthesized using a combination of electrospinning and hydrothermal techniques. Initially, polyvinyl butyral (PVB)/ZnS composite nanofibers were fabricated via electrospinning. Subsequently, a hydrothermal reaction was employed to induce a dissolution-recrystallization mechanism, enabling the gradual formation of highly crystalline ZnS nanoparticles. The structural, morphological, and compositional characteristics of the ZnS nanoparticles were analyzed using scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDS). Finally, the photocatalytic activity of three different ZnS materials—synthesized via electrospinning, hydrothermal treatment, and hydrothermal-assisted electrospinning—were More >

Abstract Interest in the use of cellulose nanomaterial’s continues to grow, both in research and industry, not only due to the abundance of raw materials, low toxicity and sustainability, but also due to the attractive physical and chemical properties that make nanocelluloses useful for a wide range of end-use applications. Among the large number of potential uses, and nanocelluloses modification and processing strategies, the chosen topic of this review focuses exclusively on plant-derived cellulose microfibers/nanofibers (CNF) and cellulose nanocrystals (CNC) processed into 2D structures—nanopapers and nanofilms—fabricated as self-standing films or applied as coatings. The end uses… More > Graphic Abstract

Abstract In the past two decades, nanocellulose has become an innovative material with unique properties. This substance has exceptional mechanical strength, an extensive surface area, and biodegradability. Collaborative integration of nanocellulose offers a more environmentally friendly solution to the current limitations by substituting carbon. Due to its versatility, nanocellulose is commonly employed in various industrial sectors, including paints, adhesives, paper production, and biodegradable polymers. Such versatility enables the creation of customized structures for potential use in emulsion and dispersion applications. Given its biocompatibility and nontoxicity, nanocellulose is particularly well-suited for biomedical purposes such as tissue engineering, More > Graphic Abstract

Abstract Bionanocomposite film is produced from renewable and biodegradable natural resources. Although elephant foot yam (EFY) starch (Amorphophallus paeoniifolius) is a promising polymer for bionanocomposite film, the native hydrophilic properties influence the overall performance characteristics. Incorporating virgin coconut oil (VCO) and monoglyceride as hydrophobic components can improve mechanical properties and reduce permeability while increasing the hydrophobicity of the composite. Therefore, this study aimed to determine the effect of adding VCO and monoglyceride on EFY starch-nanocrystalline film at 3 and 5 wt% concentrations. Experimental tests were conducted to evaluate the physical and mechanical properties, water vapor transmission rate… More > Graphic Abstract

Abstract Cu₂MgSnS₄ (CMTS) nanoparticles are successfully prepared via a solvothermal approach. X-ray diffraction (XRD) and Raman reveal that pure zinc-blende CMTS phase is obtained. Scanning electron microscopy (SEM) shows that CMTS nanoparticles exhibit microsphere structure. The band gap of as-obtained CMTS nanoparticles is calculated to be 1.68eV, indicating a potential candidate for tandem solar cells. The degradation rate of methylene blue (MB) with under visible-light irradiation is about 87%, indicating that CMTS can be useful for effective visible-light photocatalyst. More >

Abstract Nickel (Ni⁺²) doped nanocrystalline Bi₂S₃ thin films are deposited on the glass substrate from the solutions containing Bismuth Nitrate, Ethylenediamine Tetraacetic acid (EDTA) and Thioacetamide at a bath deposition temperature of 318K. The optical, surface morphological and electrical properties of Ni-doped Bi₂S₃ thin films prepared at three different doping concentration are investigate by using ultraviolet–visible transmission spectra (UV–Vis), Scanning electron microscopy (SEM), Energy Dispersive X-ray (EDAX) and thermo-e.m.f. techniques. The optical band gap energies are found in between 2.32-2.43 eV. The SEM images show that the prepared films are continuous, dense and distributed over the entire area More >

Abstract Zinc telluride (ZnTe) nanocrystals (NCs) have generated the interest of researchers as an electrode material in hybrid light emitting devices (HLEDs) due to its potentially high capacity. However, due to the restricted fundamental charging capacity of the electrode materials, the available energy of existing nanomaterial light emitting devices remains enough for a wide range of applications. In this research, ZnTe nanocrystals were synthesized using Nd: YAG laser at energy 600 mJ by 150 pulse number to form a battery device out of ITO/ZnTe/TPD/Ni. The spectra of the ZnTe NCs were assessed using ultraviolet-visible (UV-VIS) and More >
