Bacterial transmission is considered one of the potential risks for communicable diseases, requiring promising antibiotics. Traditional drugs possess a limited spectrum of effectiveness, and their frequent administration reduces effectiveness and develops resistivity. In such a situation, we are left with the option of developing novel antibiotics with higher efficiency. In this regard, nanopartic...... hiện toàn bộ

AbstractThe significance of green synthesized nanomaterials with a uniform shape, reduced sizes, superior mechanical capabilities, phase microstructure, magnetic behavior, and superior performance cannot be overemphasized. Iron oxide nanoparticles (IONPs) are found within the size range of 1–100 nm in nanomaterials and have a diverse range of applications in fields...... hiện toàn bộ
A novel concept of photosynthetic soft membranes: a numerical study
Gabriele Falciani, Luca Bergamasco, Shannon A. Bonke, Indraneel Sen, Eliodoro Chiavazzo
AbstractWe focus on a novel concept of photosynthetic soft membranes, possibly able to allow the conversion of solar energy and carbon dioxide (CO$$_2$$
2
) into green fuels. The considered membranes rely on self-assembled functional molecules in the form of soap films. We elaborate a multi-scale and multi-physics model to describe the relevant phenomena, investigating the expected performance of a single soft photosynthetic membrane. First, we present a macroscale continuum model, which accounts for the transport of gaseous and ionic species within the soap film, the chemical equilibria and the two involved photocatalytic half reactions of the CO$$_2$$ hiện toàn bộ
Facile biosynthesis of Ag–ZnO nanocomposites using Launaea cornuta leaf extract and their antimicrobial activity Tập 18 Số 1
Elizabeth Makauki, Stanslaus G. Mtavangu, Onita D. Basu, Mwemezi J. Rwiza, Revocatus L. Machunda
AbstractThe quest to synthesize safe, non-hazardous Ag–ZnO nanoomposites (NCs) with improved physical and chemical properties has necessitated green synthesis approaches. In this research, Launaea cornuta leaf extract was proposed for the green synthesis of Ag–ZnO NCs, wherein the leaf extract was used as a reducing and capping agent. The...... hiện toàn bộ
The electronic properties of boron-doped germanium nanocrystals films
Dan Shan, Menglong Wang, Daoyuan Sun, Yunqing Cao
AbstractVarious doping concentrations of boron (B)-doped germanium nanocrystal (Ge NC) films were prepared using the plasma-enhanced chemical vapor deposition (PECVD) technique followed by thermal annealing treatment. The electronic properties of B-doped Ge NCs films combined with the microstructural characterization were investigated. It is worthwhile mentioning t...... hiện toàn bộ
Improved electrical properties of micro light-emitting diode displays by ion implantation technology
Yu-Hsuan Hsu, Chi-Han Wang, Xin-Dai Lin, Yi-Hsin Lin, Dong−Sing Wuu, Ray−Hua Horng
AbstractGenerally, the inductively coupled plasma-reactive ion etching (ICP-RIE) mesa technology was used to remove p-GaN/MQWs and expose n-GaN for electrical contact in a fabricated micro light-emitting diode (μLED). In this process, the exposed sidewalls were significantly damaged which result in small-sized μLED presenting a strong size-dependent influence. Lowe...... hiện toàn bộ
Sub-bandgap near-infrared photovoltaic response in Au/Al2O3/n-Si metal–insulator–semiconductor structure by plasmon-enhanced internal photoemission
Xiyuan Dai, Wu Li, Yu Liang, Zhiyuan Yu, Fengyang Ma, Yuchen Zhang, Yan‐Ru Yang, Jian Sun, Ming Lu
AbstractSilicon sub-bandgap near-infrared (NIR) (λ > 1100 nm) photovoltaic (PV) response by plasmon-enhanced internal photoemission was investigated. The Si sub-bandgap NIR PV response, which remains unexploited in Schottky junction-like solar cell device, was examined using nanometer sized Au/Al2O3/n-Si junction arrays....... hiện toàn bộ
