Summary: In this study, SnO2 nanofibers and their modifications (Cd doping and making a composite with reduced graphene oxide) were synthesized via electrospinning and used for CO gas sensing. The enhanced sensing properties of Cd-doped SnO2-RGO nanofibrous mat, compared to other counterparts, can be attributed to the p-type behavior of RGO inside the nanofibers, catalytic activity, and the addition of new oxidation sites for cadmium elements, providing flexible and optimal gas sensing.

Summary: In this study, a composite material containing zein and C-phycocyanin (ZCPhy 20) was successfully developed using electrospinning. The addition of phycocyanin resulted in larger diameter tubular fibers. Simulation experiments provided insights into the structural changes of proteins in acidic conditions and under applied voltage. The results confirmed protein denaturation and unfolding through a helix-to-coil transition. Further characterization experiments, including FTIR, Raman, XRD, and CD, showed consistent findings with the simulations, confirming the structural changes of the proteins after electrospinning. Additionally, the thermostable ZCPhy 20, obtained from TGA thermograms, exhibited significant antioxidant activity in both native and fibrous forms, as evidenced by the DPPH assay. Lastly, ZCPhy 20 demonstrated remarkable antibacterial and anti-cancer activity against HT-29 cells. These findings highlight the potential of ZCPhy 20 composite as an edible film with medical and non-medical applications.

Summary: This research examines the synergistic antiviral effects of carbon nanotubes (CNTs) and metal oxides (MO) in the form of novel hybrid structures (MO-CNTs). The study finds that metal oxide-CNTs show higher antiviral activity compared to raw CNTs, with an average enhancement rate of 20.2%. Among all the tested compounds, Ni(OH)(2)-CNT exhibits the lowest LD50, indicating it is the most toxic. The developed metal oxide-CNT nano hybrids show promise in various applications such as antiviral coatings and nanocomposites.

Summary: Doping with rare-earth elements, a one-step hydrothermal method was used to prepare La-doped Ni-Sn oxide/reduced graphene oxide composite. The electrochemical performance of the composite was studied under different electrolyte conditions, and the LNSRG 2 composite showed good specific capacitance in 6M KOH electrolyte. An ASC device fabricated with LNSRG 2 and SRGO as positive and negative electrode materials, respectively, exhibited high energy density and good cyclic stability in 1M Na2SO4 electrolyte.

Summary: In this study, nickel-based electrochromic films were prepared by a simple hydrothermal method and CdS quantum dots sensitization. The composite films with adsorbed CdS quantum dots showed a multifunctional non-electrochromic film with multiple color changes and a high optical modulation range. The presence of CdS improved the structural stability and charge storage capacity of the composite film, enhancing the electrochromic reaction. This research provides a reference for the development of NiO polychromatic electrochromic materials and expands the range of non-electrochromic materials from metal oxides to sulfides.
