The Influence of Al Doping on the Optical Characteristics of ZnO Nanopowders Obtained by the Low-Cost Sol-Gel Method

Chemistry, 2022
In this work, the influence of Al (0, 2, 4, and 6 wt.%) on the optical properties of ZnO has been briefly investigated and described. The undoped and doped samples were characterized using a UV-visible spectrophotometer and Photoluminescence (PL).

Aged ZnO Nanoparticles Promote Breast Cancer Lung Metastasis by Remodeling the Pulmonary Microenvironment Through the CXCL10/Wnt/β‐Catenin Axis

Advanced Science, EarlyView.
In summary, pulmonary exposure to ZnO NPs, particularly aged NPs, promotes breast cancer metastasis by remodelling the lung tumour microenvironment. Aged ZnO NPs enrich M2‐macrophages, MDSCs and activated CAFs to form an immunosuppressive metastatic niche. CXCL10 from these cells drives metastasis via Wnt/β‐catenin activation.

Energy storage in aluminum nanopowder in stress-strain state of crystal lattice

Известия Томского политехнического университета: Инжиниринг георесурсов, 2017
When transforming metals into nanodispersed state nanopowders acquire new properties, including the storage of energy by nonopowders. The increasing interest to aluminum powders and nanopowders is caused by their application as a high-energy additive in ...

Surface‐State‐Driven Selectivity of Electrocatalytic Glucose Oxidation: Metallic Au, Au─OH, and CuO

Advanced Science, EarlyView.
In the electrochemical oxidation of glucose, whether the pyranose ring opens upon adsorption decides the reaction pathway: ring opening on metallic Au yields gluconic acid, gluconolactone formation on Au─OH leads to glucaric acid, and C─C cleavage on CuO gives formic acid. Surface state thus governs product selectivity.
