This study employs the tight-binding density functional method GFN1-xTB to investigate the structural and electronic properties of TiO2-ZnO and TiO2-ZnO composite materials modified by Li, Na, K, and Fe metals. Computational analyses reveal the formation of weak covalent bonds between the TiO2 and ZnO components within the composite system. Doping TiO2-ZnO with metals induces significant alterations in the electronic structure, particularly in terms of ionization energy and global electrophilic index.

This study investigated the in vitro effects of ZnO NP and chemical UV filters commonly used sunscreens on the function of immortalised and primary skin cells. ZnO particulates (30 nm, 80 nm and 200 nm) were compared to the chemical UV filters: butylmethoxydibenzoylmethane (BMDBM) ethylhexylmethoxycinnamate (EHMC), ethylhexylsalicylate (EHS), homomenthylsalicylate (HMS) and 4-methylbenzylidenecamphor (MBC). Human epidermal keratinocytes (NHEK), epidermal melanocytes (NHEM), dermal fibroblasts (NHDF) and the immortalised keratinocyte HaCaT cell line were used in this study.

This paper simulates an optical sensor utilizing a prism based on surface plasmon resonance (SPR). The simulations combine a layer of Au and an additional layer of different materials: aluminum arsenide (AlAs), poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), zinc oxide (ZnO), and polydimethylsiloxane (PDMS) for SPR excitation. The simulations show that a sensor based on a combination of Au/PEDOT:PSS layers with thicknesses of 40 nm and 5 nm, respectively, offers a sensor sensitivity of 186.07°/RIU, which is 1.2 times better than that of a sensor using only a thin Au layer.

In this paper, we present one method to determine the band gap energy of ZnO and ZnO:Tb3 materials. ZnO:Tb3 material has prepared by forced hydrolysis method. All samples have zinc oxide hexagonal wurzite structure. The obtained results show that the energy of the band gap depends on Tb3 molar ratio.

To investigate the changes in the haematological, serum biochemical parameters and hepato-renal biomarkers upon dietary supplementation of nano zinc oxide (nZnO) and its effect on growth performance in calves, 24 weaned (6 months age) crossbred calves were randomly distributed to four dietary plans (Control, Treatment1, Treatment2 and Treatment3). The Control(C) group was fed exclusively with basal diet; T1 was supplemented with 25ppm ZnSo4, T2 and T3 with 5ppm and 10ppm nZnO respectively, along with the basal diet. Zinc content in basal was 26.24ppm.

An RBCC (RING finger, B-box, and coiled-coil) protein was identified that belongs to the superfamilyof zinc-binding proteins and is specifically expressed in the gill of eel, Anguilla japonica. Euryhaline fishes such as eels canmigrate between freshwater and seawater, which is considered to be accomplished by efficient remodeling of the architecture and function of the gill, a major osmoregulatory organ.

Thec-secretase complex mediates the final proteolytic event in Alzheimer’s disease amyloid-bbiogenesis. This membrane complex of presenilin, ante-rior pharynx defective, nicastrin, and presenilin enhancer-2 cleaves the C-terminal 99-amino acid fragment of the amyloid precursor protein intra-membranously atc-sites to form C-terminally heterogeneous amyloid-b and cleaves at ane-site to release the intracellular domain or e-C-terminal fragment.
