Natural biomass-derived carbon materials, renowned for their inherent porosity and distinctive structural attributes, have become the focus of extensive research and application. The incorporation of heteroatom doping further amplifies their appeal due to the inherent advantages it confers. A hierarchical porous carbon framework derived from biomass was synthesized by direct carbonization of cotton. The strategic optimization of the synthesis parameters during thermochemical treatment to preserve the inherent tubular fiber structure of cotton and regulate the pore structure to effectively mitigate the inherent shuttle effect of zinc-iodine batteries (ZIBs). The electrochemical performance of the synthesized cathode material is impressive. The SPC750-2/I2 (spiral porous carbon) electrode exhibits robust performance with 88 % capacity retention after 10,000 cycles at a current density of 2 A/g. This durability and stability at a high current density suggests that the material has potential for high-performance energy storage applications and is important for the sustainable utilization of low-cost, excess biomass.

The present study was based on green protocols for synthesizing cobalt sulfide nanoparticles using saffron stigma flower extract (Crocus sativus), as saffron is considered a potent traditional medicine. The novel cobalt sulfide (CoS) nanoparticles prepared by the green approach for the first time with saffron improved showed cytotoxicity and antibacterial activity, as well as significant antitumor activity of Hela, A549, and MCF 7 cells viz in vitro studies. The saffron-cobalt sulfide nanoparticles underwent characterization using various techniques which include the X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Advances in scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HR-TEM), and the energy dispersive X-ray analysis spectroscopy. Both XRD, and FTIR confirmed the synthesis of pure cobalt sulfide nanoparticles. The resulting saffron-based cobalt sulfide nanoparticles exhibited a nanosphere structure, as confirmed by HRTEM, indicating the formation of nanosphere and microstructures. In vitro studies were conducted to assess the cytotoxicity and cell viability of Hela cells, A549, and MCF-7 cells. And, antibacterial studies were performed against various bacterial strains using different concentrations of cobalt sulfide nanoparticles derived from the red stigma of saffron (Crocus sativus) only the red stigma extract. The MTT assay analysis, cell viability, and morphological studies demonstrated the cytotoxic studies of the synthesized cobalt sulfide nanoparticles on cancer cells. The antibacterial test of the nanoparticles was also evaluated, revealing significant zones of inhibition (mm) against pathogens and cobalt sulfide nanoparticles using saffron extract, showcasing their potent cytotoxic, antibacterial, and antitumor activities with promising biomedical applications.

The assembly of [Et4N][Tp*WS3] (Et = ethyl, Tp* = tetrakis(3,5-dimethyl-1-pyrazolyl)borate), Cu(I) with 1,3,5-tri((pyridin-4-ylthio)methyl)benzene (tptmb) or 4,4′-bis((pyridin-4-ylthio)methyl)-1,1′-biphenyl (bptmb) leads to two coordination polymer with the formulae of {[Tp*WS3Cu3(tptmb)(CH3CN)](PF6)2·CHCl3·2CH3CN}n (1·CHCl3·2CH3CN) and {[(Tp*WS3Cu3)2(bptmb)3(CH3CN)](PF6)4·5CH2Cl2·1.5CH3CN}n (2·5CH2Cl2·1.5CH3CN), respectively. Compounds 1 and 2 were characterized by elemental analysis, infrared spectroscopy, UV–vis spectroscopy, high-resolution electrospray ionization mass spectrometry, and single-crystal X-ray diffraction. In 1, each tptmb ligand connects two adjacent cluster nodes by its three coordination arms, forming a cluster-based one-dimensional zigzag chain. In 2, equal amounts of [Tp*WS3Cu3(CH3CN)]2+ and [Tp*WS3Cu3]2+ clusters serve as three-connected nodes and are alternatively bridged by the bptmb ligands, forming a 2D network. Z-scan tests of 1 and 2 in dimethylformamide (DMF) solution reveal they have reverse saturable absorption with effective nonlinear absorption coefficients of 1.50 × 10−11 m/W for 1 and 5.00 × 10−11 m/W for 2. This work could inspire the construction of coordination polymer structures using cluster nodes and flexible thioether-containing ligands, providing a new way for the development of third-order nonlinear optical materials.

The demand for affordable and eco-friendly energy storage solutions is essential to meeting the challenges of integrating next-generation energy sources. Supercapacitors (SCs) have the potential to be a key electrochemical storage technology for intermittent renewable energy sources due to their long cycle life, rapid charging/discharging rates, and high power density. However, their relatively low energy density remains a challenge. Extensive research has been conducted on electrode materials, particularly transition metal oxide (TMO) composites, to assess their value in the SC field. However, TMOs face significant challenges, such as limited electron and ion transport and poor electronic conductivity, which hinder their electrochemical performance in energy storage applications. Therefore, integrating carbon-based materials or conductive polymers presents a promising strategy for achieving higher energy density, enhanced specific power, and faster charging/discharging rates, thereby improving the overall efficiency of SCs. This review provides recent advancements in TMOs and their binary and ternary composites, emphasizing synthesis methods and their effects on electrochemical performance, while highlighting the potential of flexible and sustainable supercapacitors to meet increasing energy demands. Finally, the discussion on the current challenges and future outlook for these materials in supercapacitors as energy storage solutions will open avenues for further research and exploration.

The synthesis of nanoparticles using plant extracts presents an innovative alternative to traditional chemical or physical methods. Natural nanoparticle synthesis using plant extracts has several advantages over traditional methods, including less reliance on synthetic chemicals, a reduced environmental impact, the potential to synthesize unique nanoparticle characteristics, and the production of biocompatible and biodegradable materials. This strategy is a sustainable and effective alternative. The antimicrobial activity of Ag-decorated ZnO/MgO from the leaves extract of Polygonum chinensis has been demonstrated in the present work. UV–vis, XRD, FTIR, and SEM-EDX were used to assess the bio-synthesized nanocomposite after the effective synthesis of Ag-decorated ZnO/MgO nanocomposite. The UV spectrum of the synthesized Ag-decorated ZnO/MgO nanocomposite showed a peak at 225 nm, with a band gap energy of 4.30 eV. The nanocomposite was confirmed with irregular flakes-like structure with range in size from 70 to 150 nm using SEM analysis. Standardized tests used in antimicrobial analysis were used to investigate the antimicrobial activity of Ag-decorated ZnO/MgO nanocomposite against various microorganisms. Biofilm inhibition studies confirmed the nanocomposite’s inhibitory effect on various bacteria. The findings indicated that Ag-decorated ZnO/MgO nanocomposite is a promising antimicrobial and antifilm agent.

The study focuses on a complete modelling of perovskite solar cell (PSC) employing methyl ammonium germanium iodide (MAGeI3) as light absorbing material via optimizing device’s conduction band offset (CBO) and valence band offset (VBO), which helps in identifying the suitable transport materials that can be employed for extracting the best photovoltaic parameters for solar cell. The device architecture FTO/TiO2/MAGeI3/CuO/Pd has been considered for the study, which after the input parameter optimization provides a power conversion efficiency (PCE) of 12.33 %. An optimization of the CBO of the device configuration results in a PCE of 13.57 %, indicating that the chosen ETL, TiO2 is suitable for the device configuration. An alternate ETL, IGZO with the required electron affinity of 4.18 eV, when tested for the device shows a PCE of 12.39 %. The VBO optimization of the device configuration FTO/TiO2/MAGeI3/CuO/Pd suggests the inclusion of CZTS as the HTL and further input parameter optimization of the device provides PCE of 16.59 %. The VBO optimization of FTO/IGZO/MAGeI3/CuO/Pd suggests for the inclusion of CZTS as the HTL, and provides an excellent PCE of 14.57 %. Hence, the CBO and VBO optimized device configuration, FTO/IGZO/MAGeI3/CZTS/Pd is again optimized by changing the parameters of perovskite and transport layers and a PCE of 20.54 % is achieved. It is further analysed considering diverse back contact metal and optimum PCE of 20.57 % is attained, with Se as the back metal contact. An estimation of the QE of FTO/IGZO/MAGeI3/CZTS/Se configuration indicates efficient charge generation and collection in visible and NIR wavelength regimes.

The simple, fast, efficient route and eco-friendly synthesis of silver nanoparticles (Ag-NPs) using the marine-algae Padina pavonica (PP) extracts. The heat bio-reduction process involves using PP extract mediated to synthesize silver (Ag) nanoparticles (NPs). The PP extract provides an eco-friendly, low-cost, and safer alternative to traditional chemical and physical methods. The GC–MS results detect GLYCERYL TRIDODECANOATE, DODECANOIC ACID, and 1,2,3-PROPANETR dominantly examined majorly play a role in synthesizing the Ag-NPs. The synthesized PP-mediated NPs were denoted as PPAg-NPs and characterized the structural and morphological properties by UV–vis spectroscopy, XRD, SEM, HRTEM, EDS, DLS, and FT-IR. The 16S rDNA technique confirmed 6 (n = 6) human pathogens (HPs) strains were used for the antimicrobial study. Green synthesized PPAg-NPs showed a maximum and minimum inhibition growth zone of 16 mm in Escherichia coli, and 10 mm in Bacillus subtilis. The study result suggested the PPAg-NPs act with high efficiency and display greater sensitivity for antibacterial material depending on the concentrations. The synthesized green PPAg-NPs investigated the photocatalytic degradation of methylene blue (MB) dye. The highest 90 % efficiency was achieved under UV-light treatment within 105 min. The study’s outcome indicates that PPAg-NPs exhibit a strong antimicrobial efficacy toward HPs and MB decolorization that contributes to water cleansing, healthcare, and biomedical industries.

In this study, five samples of Gd2O3 NPs (size range: 4–33 nm) were synthesized by five different green facile and diverse natural products acting as reducing & stabilizing agents such as: fresh juices of sugarcane, lemon, tomato & orange fruits and citric acid via self-combustion sol–gel tactics. Powder X-ray diffraction (PXRD), High resolution transmission electron microscopy (HRTEM), Fourier transform infrared (FTIR) and Raman analysis affirmed cubic-C type crystal structure of Gd2O3 NPs prepared using citric acid, lemon juice and sugarcane juice. Mixed cubic and monoclinic phases were observed in Gd2O3 NPs prepared using tomato and orange juices. Notably, NPs of Gd2O3 in quantum dot regime (size: 6 ± 2 nm) were produced in the fresh sugarcane juice mediated synthesis protocol. Fresh lemon juice and sugarcane juice were appeared to be the most efficient green fuel for producing quality samples of Gd2O3 NPs. Optical absorption studies showed that bandgap in these Gd2O3 NPs is strongly dependent on the preparation protocol and type of green fuel. Interestingly, highest and lowest band gap of 4.91 eV and 4.43 eV were obtained for Gd2O3 NPs fabricated with orange and lemon juices, respectively. Photoluminescence (PL) and electron spin resonance (ESR) analysis affirmed formation of Schottky and Frenkel surface defects along with self trapped excitons and oxygen vacancies in these Gd2O3 NPs. Paramagnetic character of these Gd2O3 NPs at 300 K is validated by dc-magnetization and ESR studies. Present study demonstrated that microstructural, optical absorption and photoluminescence properties of Gd2O3 NPs can be easily customized by choice of natural products in the synthesis tactics.

In this comprehensive study, we investigated PVDF composites incorporating LaBiFeO3-BaTiO3 (LaBiFO-BaTO) perovskite fillers, focusing on their structural, optical, dielectric, impedance, modulus and DC-conductivity properties. The fabrication involved precise preparation of LaBiFO-BaTO perovskite via solid-state reaction, ensuring phase purity conducive to composite integration. Using a solution casting method, PVDF films with varying LaBiFO-BaTO concentrations (5 %, 10 %, and 15 % wt) were successfully synthesized. XRD confirmed the synthesis of single-phase LaBiFO-BaTO and revealed structural modifications in PVDF composites, highlighting improved filler-matrix interactions at higher concentrations. Scanning electron microscopy and atomic force microscopy depicted the morphological evolution and surface roughness changes with increasing filler content. Optical studies indicated a red shift in absorption spectra with higher LaBiFO-BaTO concentrations, correlating with a decrease in the direct band gap energy of the composites. Electrical characterization demonstrated enhanced dielectric properties and impedance behaviour in PVDF/LaBiFO-BaTO composites, suggesting their suitability for applications in capacitors and optoelectronic devices. This systematic investigation provides valuable insights into optimizing PVDF-based composites for advanced functional materials. The composites exhibit enhanced dielectric permittivity at room temperature, attributed to space charge polarization and the high dielectric constant of LaBiFO-BaTO. Dielectric loss (tanδ) remains minimal (<0.1), decreasing with frequency, indicative of low energy dissipation suitable for high-frequency applications. Further the dielectric relaxation have been examined using Havrilak-Negami model. Impedance and modulus analyses reveal temperature-dependent behaviours, with reduced impedance and enhanced charge transfer kinetics in higher concentration composites. DC conductivity measurements demonstrate increased charge transport properties with temperature, influenced by thermally activated charge hopping mechanisms. Overall, PVDF/LaBiFO-BaTO composites show promising characteristics for capacitors, sensors, and optoelectronic devices, suggesting avenues for further optimization and broader application in advanced technologies.

The Silicon heterojunction (SHJ) solar cell belongs to the most viable cell structure that enables low cost as well as high efficiency. For SHJ cells, silver (Ag) paste has been used through screen-printed process that is hardenable at low temperature. The procedure of screen printing is essential for improving the electrical properties because it allows electrodes to make good contact with the top layer of solar cells. This paper describes the experimental procedure to optimize the process condition for achieving comparatively high efficiency with minimum usage of Ag consumption. It was noticed that adequate contact among electrodes and uppermost transparent conductive oxide layer in SHJ solar cell depending considerably on squeeze speed, squeegee pressure, scraper speed, curing time and temperature. By controlling the snap-off distance of 1.4 mm, squeegee pressure at 0.3 MPa, scraper speed of 10 mm/sec, squeegee speed of 170 mm/sec, curing time of 20 min and curing temperature of 190 °C respectively, we achieved comparatively high efficiency of 22.46 %.
