Tuning the Surface State and Zeta Potential of Aged CuO Nanoparticles by Additive‐Free Surface Treatments as Guided by XPS

open access: yesAdvanced Materials, EarlyView.
Aging of CuO nanoparticles (NP) involves a surface reconstruction induced by hydroxylation and concurrent organic‐O adsorption, which introduces O defects in the NP subsurface region. The defective surface results in a diffuse surface space region, as reflected by a low ζ‐potential of the aged NPs in ethanol solvent.

MXene Membrane as Multifunctional Interface for Vapor Splitting via Photothermal‐Catalytic Membrane Distillation

open access: yesAdvanced Materials, EarlyView.
A multifunctional MXene‐based membrane integrates photothermal evaporation and photocatalytic vapor splitting in a sweeping‐gas membrane distillation (PTC‐SGMD) platform, simultaneously generating freshwater and hydrogen. The SrTiO3/MX@PVDF interface leverages broad‐spectrum solar absorption, efficient heat/mass transfer, and gas–solid catalysis to ...

Tetramethylenedisulfotetramine [PDF]

open access: yes, 2014
Tetramethylenedisulfotetramine (CAS 80-12-6), commonly referred to as TETS, was first synthesized in 1933 as a condensation product of sulfamide and formaldehyde. TETS was subsequently used as a rodenticide until banned worldwide in 1991.

Stabilizing Frustrated Phase Transitions in Selective Oxidation Reactions

open access: yesAdvanced Materials, EarlyView.
Using multimodal operando spectromicroscopy, the frustrated phase transition responsible for selective oxidation over cobalt oxide spinel catalysts is identified, corresponding to combined surface reaction and Mars‐van Krevelen (MvK) dynamics. This regime is disrupted by the formation of mobile vacancies and the depletion of active oxygen at high ...

High‐Performance Zero‐Gap Glycerol‐Fed Electrolyzer for C3 Chemicals and Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
This work presents a dynamic, self‐regulating operation strategy that enables selective glycerol electrooxidation in the OER‐free regime, co‐producing C3 chemicals and hydrogen at cell voltages below 1.25 V. Voltage‐ and temperature‐resolved analyses define optimal operating conditions, achieving a sustained current density of 500 mA cm−2 at ∼1.21 V ...

Toxicological Profile of Acutely Poisoned Cases Admitted to Poison Control Center, Ain-Shams University Hospitals during Year 2013

open access: yes, 2015
Introduction oisoning is considered a major global health problem that mandate emergency hospitalization (Gurung et., al; 2011). Substantial differences in socioeconomic and cultural situations in different countries cause various patterns of poisoning ...

Maximize the Electrocatalytic Activity of Pt Toward Ethanol Oxidation via Engineering PdPt1 Single‐Atom Alloy Skin

open access: yesAdvanced Materials, EarlyView.
Maximizing atomic utilization of Pt is crucial for efficient electrocatalysis. We constructed a tensile‐strained PdPt1 single‐atom alloy (SAA) skin by implanting atomically dispersed Pt onto the surface of intermetallic Pd5Bi3 core‐ultrathin Pd shell octahedrons, fully exposing active Pt atoms to boost ethanol oxidation electrocatalysis.

Evaluation of the therapeutic and toxicological knowledge of herbalists on the most notified plants in the poison control and pharmacovigilance center of Morocco

open access: yes, 2018
According to the World Health Organization, 80% of the population in developing countries is engaged in traditional medicine. Consequently, the issue of poisoning by plants is not negligible.
