A new imaging method of fluorescence induced by multispectral UV for studying historical musical instruments coatings

open access: yes, 2020
In art conservation, UV luminescence is a widespread technique: traditionally, long wave UV-A lamps (365 nm-emission peak) are used to highlight the distribution of varnishes or retouches, and of some pigments such as the red lakes.

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

open access: yesAdvanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Oxygen‐Tunnel Indium Tin Oxide Vertical Channel Transistors with Enhanced Current Density and Reliability for Monolithic 3D Compute‐In‐Memory Systems

open access: yesAdvanced Functional Materials, EarlyView.
Oxygen‐tunnel (OT) indium tin oxide (ITO) vertical channel transistors (VCTs) enable reliable, high‐density gain‐cell memory for monolithic 3D integration. A sandwiched SiN/SiO2/SiN OT stack selectively regulates oxygen transport, suppressing parasitic electrode oxidation while stabilizing channel oxygen vacancies, thereby suppressing carrier injection

A HPLC-UV Method for Determination of Three Pesticides in Water

open access: yesInternational Journal of Advances in Chemistry, 2016
HPLC method is developed and validated for determination of three pesticides (abamectin, imidacloprid, and β-cyfluthrin) in water. These pesticides are used widely in agriculture for crops protection, and may be leached to the groundwater. Reversed-phase method with C18 column (5 µm, 250mm × 4.6 mm inner diameter) using a mobile phase consisting of ...
