Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

open access: yesAdvanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...

Simultaneously Engineering the Amorphous Phase and Branch Morphology of High‐Entropy Alloy Nanomaterials for Enhanced Ethylene Glycol Oxidation

open access: yesAdvanced Materials, EarlyView.
Amorphous PdCuNiCoFe high‐entropy alloy nanobranches were developed through a versatile wet‐chemical synthetic strategy enabling simultaneous control of composition, phase, and morphology. The resulting amorphous PdCuNiCoFe nanobranches exhibit outstanding electrocatalytic performances for ethylene glycol oxidation (EGOR), delivering high selectivity ...

Amitraz poisoning: The (Un) common poisoning

open access: yesJournal of Emergencies, Trauma, and Shock, 2018
Pesticide poisoning is always a clinical conundrum for the emergency physician (EP), the complexity of which increases when the pesticide has no antidote! Over the past decade, there has been a sharp increase in cases of Amitraz poisoning, a pesticide routinely used in veterinary medicine, available without a prescription.

Methanol‐Ethanol Discrimination and Selective Sensing Enabled by Molecular Sieving in Conductive MOFs

open access: yesAdvanced Materials, EarlyView.
Selective methanol sensors are achieved by coating carbon nanotube chemiresistors with two dimensional conductive metal–organic frameworks that incorporate intra‐pore clusters. These confined clusters increase the density of adsorption sites while restricting the transport of larger interfering molecules, particularly ethanol. This sensing architecture

A promising poison information centre model for Africa

open access: yesAfrican Journal of Emergency Medicine, 2016
The burden of poisoning exposures in Africa is a significant public health concern, yet only ten African countries have poisons information centres. The establishment of poisons centres was subsequently identified as a priority.

Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells

open access: yesAdvanced Materials Technologies, EarlyView.
Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.

Awareness and attitude toward household poisons among medical and nonmedical students: A comparative study

open access: yesIndian Journal of Health Sciences and Biomedical Research KLEU, 2018
INTRODUCTION: There are innumerable things we use in our household on day-to-day basis. Many things that we use at home from cleaning products to cosmetics are toxic when we are not careful about them.
