• Decomposition of textile products in the ground

  Like all organic materials, textiles will decompose under the influence of water and microorganisms in the ground. Under comparable environmental conditions, it depends mainly on the raw materials used whether the decomposition process takes place over the course of months, years, decades or even ce more

• A Bright Future for Silicon

  US scientists at the University of Texas at Austin and Cornell University have fabricated the first ordered arrays of silicon nanocrystals reported to date. Brian A. Korgel and colleagues developed a new chemical method to generate tiny silicon crystals—or quantum dots—with precisely controlled size more

• Graphene: Singles and the few

  A timely review analyzing the correlation of synthesis methods and physical properties of single-layer and few-layered graphene flakes. A review of methods used for synthesizing both single and few-layer graphene and the resulting properties is presented by C.N.R. Rao and colleagues at the Jawaharla more

• Sum parameters "on trail"
  

  Identification of organic pollutants in wastewater is essential for performance evaluation, construction and operation of a wastewater treatment plant. Several parameters are currently used in wastewater analysis applications. The advantages of TOC analyses are apparent especially during continuous monitoring more

• ORAC Assay Performed on the POLARstar Omega and PHERAstar FS microplate reader
  

  In all oxygen consuming cells, metabolism and oxidative stress generate several intermediates and byproducts that are collectively known as reactive oxygen species (ROS). ROS are necessary intermediates in the human body, but they are also involved in the aging process and in the development of many degenerative diseases, including cancer, heart disease, Alzheimer's and Parkinson's. Herein we describe the determination of the antioxidant capacity of different fruit juices using the ORAC assay; a standardized method that uses Trolox®, a water-soluble analogue of vitamin E, as a standard substance more

• Battery Safety (thermal runaway)
  

  Lithium ion battery technology offers many advantages in portable power application but one major concern is safety – thermal runaway of the device in both normal and abusive situations. In the following article, it will be shown that by means of adiabatic calorimetry, it is not only possible to test single components but also complete lithium ion batteries. From this information batteries can be evaluated for their hazards potential, but more importantly, these tests can be used to design inherently safer cells, providing key design information during the development process – reducing development costs and increasing product safety more

• The Pursuit of Rechargeable Solid-State Li-Air Batteries

  Li-air batteries have received much attention in the past several years, because of large theoretical specific energy density, but the challenges and problems with the electrolytes are the main hindrance for the development of Li-air batteries. Particularly, the electrolyte decomposition and reactiv more

• Specific properties on TiO2 photocatalysis to decompose isopropyl methylphosphonofluoridate and dimethyl methylphosphonate in Gas Phase

• Temperature Dependence and Energetics of Single Ions at the Aqueous Liquid–Vapor Interface

  We investigate temperature-dependence of free energetics with two single halide anions, I– and Cl–, crossing the aqueous liquid–vapor interface through molecular dynamics simulations. The result shows that I– has a modest surface stability of 0.5 kcal/mol at 300 K and the stability decreases as the more
