Selective Styrene Oxidation Catalyzed by Phosphate Modified Mesoporous Titanium Silicate

open access: yesChemistry, 2023
Selective oxidation of organics over an efficient heterogeneous catalyst under mild liquid phase conditions is a very demanding chemical reaction. Herein, we first report the modification of the surface of mesoporous silica MCM-41 material by phosphate ...

Design of Currency Sanitizer using UV-C Light

open access: yesInternational Journal for Research in Applied Science and Engineering Technology, 2021
Currency is the primary mode of transmission of microbes and infection. Currency sanitization is a simple and least expensive means of preventing infection. Various sanitizing products are on the market in the form of antimicrobial and alcohol-based sanitizers which are meant to reduce/remove microbial load of the skin.

Lepton flavour violation: physics potential of a Linear Collider [PDF]

open access: yes, 2012
We revisit the potential of a Linear Collider concerning the study of lepton flavour violation, in view of new LHC bounds and of the (very) recent developments in lepton physics. Working in the framework of a type I supersymmetric seesaw, we evaluate the

The Effect of LEDs on Biomass and Phycobiliproteins Production in Thermotolerant Oscillatoria sp.

open access: yesApplied Sciences, 2022
This study evaluates the role of different LED lights (white, blue/red), intensity (µmol m−2 s−1), and photoperiod in the production of biomass and phycocyanin-C, allophycocyanin and phycoerythrin (C-PC, APC, and PE respectively) from a novel ...

Visible light reduces C. elegans longevity

open access: yesNature Communications, 2018
The nematode C. elegans is known to alter its behavior in response to UV light. Here, the authors show that visible light triggers photo-oxidative stress and a wider stress response in C.

Optimization conditions of UV-C radiation combined with ultrasound-assisted extraction of cherry tomato (Lycopersicon esculentum) lycopene extract [PDF]

open access: yes, 2019
The aim of this work was to study the effect of UV-C radiation on ultrasound assisted extraction (UAE) of cherry tomato bioactive compounds. Cherry tomatoes were exposed to two UV-C radiation doses (0.5 and 1.0 J cm−2 ) and stored at 20 ± 0.5 oC for 7

Dissociative electron attachment to the H2O molecule. II. Nuclear dynamics on coupled electronic surfaces within the local complex potential model [PDF]

open access: yes, 2006
We report the results of a first-principles study of dissociative electron attachment to H2O. The cross sections are obtained from nuclear dynamics calculations carried out in full dimensionality within the local complex potential model by using the ...

Lifestyle Behaviors and Cardiotoxic Treatment Risks in Adult Childhood Cancer Survivors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Higher doses of anthracyclines and heart‐relevant radiotherapy increase cardiovascular disease (CVD) risk. This study assessed CVD and CVD risk factors among adult childhood cancer survivors (CCSs) across cardiotoxic treatment risk groups and examined associations between lifestyle behaviors and treatment risks.
