Structure and photocatalytic activity of maleic anhydride-functionalized TiO2 nanoparticles by a simple method
(BMC, 2022)"Titanium dioxide (TiO2) nanoparticles were functionalized with maleic anhydride (MA). The extension of adsorbed MA on the TiO2 was evaluated by ultrasonic and magnetic stirring. Total Organic Carbon and Thermogravimetric ... -
Interactions between pH, reactive species, and cells in plasma-activated water can remove algae
(Royal Society of Chemistry, 2022)"Lightning strikes cause nitrogen to dissolve in water and form reactive nitrogen and oxygen species, which form natural fertilizers that can be absorbed through plant roots. Such processes during rainstorm events can be ... -
Relativistic hyperbolic motion and its higher order kinematic quantities
(Sociedad Mexicana de Física, A.C., 2022)"We investigate the kinematics of the motion of an observer with constant proper acceleration (relativistic hyperbolic motion) in 1+1 and 1+3 dimensional Minkowski spacetimes. We provide explicit formulas for all the ... -
Optical sectioning of unlabeled samples using bright-field microscopy
(National Academy of Science, 2022)"The bright-field (BF) optical microscope is a traditional bioimaging tool that has been recently tested for depth discrimination during evaluation of specimen morphology; however, existing approaches require dedicated ... -
Calculation of conic constants for thick lenses to get diffraction-limited images using 3rd order design and marginal skew ray tracing
(Elsevier, 2022)"We calculate equations to obtain the exact and third-order design of thick lenses free from spherical and coma aberrations at two points, at the edge and center of the lens, considering the shape factor and the conic ... -
Vanishing Poynting Observers and Electromagnetic Field Classification in Kerr and Kerr-Newman Spacetimes
(Hindawi, 2022)"We consider electromagnetic fields having an angular momentum density in a locally nonrotating reference frame in Schwarzschild, Kerr, and Kerr-Newman spacetimes. The nature of such fields is assessed with two families ... -
Effect of Pluronic P103 Concentration on the Simple Synthesis of Ag and Au Nanoparticles and Their Application in Anatase-TiO2 Decoration for Its Use in Photocatalysis
(MDPI, 2022)"Silver and gold nanoparticles were synthesized under environmentally-friendly reaction conditions by using a biodegradable copolymer and water as a solvent. The triblock copolymer Pluronic P103 was utilized as a stabilizing ... -
Gating and anion selectivity are reciprocally regulated in TMEM16A (ANO1)
(Rockefeller University Press, 2022)"Numerous essential physiological processes depend on the TMEM16A-mediated Ca2+-activated chloride fluxes. Extensive structure-function studies have helped to elucidate the Ca2+ gating mechanism of TMEM16A, revealing a ... -
Sensing Eating Events in Context: A Smartphone-Only Approach
(IEEE, 2022)"While the task of automatically detecting eating events has been examined in prior work using various wearable devices, the use of smartphones as standalone devices to infer eating events remains an open issue. This paper ... -
