Colorimetric Detection of Carcinogenic Alkylating Fumigants on Nylon-6 Nanofibrous Membrane. Part I: Investigation of 4-( p-Nitrobenzyl) Pyridine as A “New” Sensing Agent with Ultra-High Sensitivity.

Alkylating fumigants are widely used in agricultural production for the control of soil-borne pests, but the acute toxicity and carcinogenicity of these chemicals pose a health threat to farm workers as well as residents. A nanofibrous membrane-based colorimetric sensor relying on the nucleophilic substitution reaction of 4-(p-nitrobenzyl) pyridine (NBP) is introduced for the convenient and

Here’s How ‘Flesh-Eating’ Bacteria Feast on Your Flesh

"Flesh-eating" bacteria can cause serious infections that can result in loss of limbs and even death. Now, a new study reveals just how the bacteria thrive deep in muscle tissue and cause such severe disease. The study focused on bacteria called group A Streptococcus, the most common cause of "flesh-eating" disease. The researchers found that

Platinum forms nano-bubbles

Platinum, a noble metal, is oxidised more quickly than expected under conditions that are technologically relevant. This has emerged from a study jointly conducted by the DESY NanoLab and the University of Vienna. Devices that contain platinum, such as the catalytic converters used to reduce exhaust emissions in cars, can suffer a loss in efficacy

EPA Releases PFAS Action Plan

The United States Environmental Protection Agency has released its much anticipated PFAS Action Plan, originally slated for release last fall. EPA Acting Administrator Andrew Wheeler held a webcast press conference on 14 February 2019, to announce the elements of EPA’s plan. States, individuals and the regulated community have been awaiting this plan and for EPA

Graphene and related materials safety: Human health and the environment

As the drive to commercialise graphene continues, it is important that all safety aspects are thoroughly researched and understood. The Graphene Flagship project has a dedicated Work Package studying the impact of graphene and related materials on our health, as well as their environmental impact. This enables safety by design to become a core part

Better batteries: The energy implications of organic radical polymers

Texas A&M University professor Dr. Jodie L. Lutkenhaus is one step closer to realising her goal of creating a battery made entirely of polymers, which has the potential to charge and discharge much faster than traditional batteries. Lutkenhaus, an associate professor in the Artie McFerrin Department of Chemical Engineering, has detailed her most recent findings

Thermal Fatigue Probable Cause of Enterprise Products Explosion: CSB

The United States Chemical Safety Board released its final report on the 27 June 2016, explosion and fire at the Enterprise Products Pascagoula Gas Plant in Pascagoula, Miss., with the board finding the probable cause was thermal fatigue in a brazed aluminium heat exchanger (BAHX). The board issued recommendations to two trade associations and local

Insomnia Isn’t Just One Disorder, Says New Study

Researchers have come up with five different types of insomnia – types that might help doctors personalise specific treatments in the future, making them more effective and better tailored towards each individual with sleep problems. Contrary to what you might expect, these groupings aren't actually based on your typical sleep symptoms, such as trouble waking

The Natural Products that could replace plastic

Drinking straws and polythene bags may be bearing the brunt of the backlash, but the true scourge of single-use plastics is our sheer overreliance on them. From transport to manufacturing to food services, plastic is everywhere, and combatting this “white pollution” will require a sea change in the material itself. Fortunately, scientists, engineers and designers

Acrylic Acid

Acrylic acid (IUPAC: prop-2-enoic acid) is an organic compound with the formula CH2=CHCO2H. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. This colourless liquid has a characteristic acrid or tart smell. [1] It is miscible with water, alcohol, ether, benzene, chloroform, and acetone. It
