How to Compare and Select Flame Retardants for Rigid Polyurethane Foam

Polyurethane (PU) foam is synthesised via a polymerisation reaction of polyol and isocyanate, in the presence of various formulations of catalysts and surfactants. For this reason, depending on the composition, PU foam can be tailor-made into flexible foams, semi-rigid foams, and/or rigid foams, resulting in a wide range of products with unique properties.

Photocatalytic Degradation of Organic Dyes Using Titanium Dioxide (TiO2) and Mg-TiO2 Nanoparticles

Titanium dioxide (TiO2 ) based nano-sized photocatalysts (NPCs) were synthesized following a green method from the extract of Peepal (Ficus religiosa) leaves and titanium tetrachloride as precursors. Doping of TiO2 with Magnesium (Mg) was done using magnesium chloride through the method of chemical precipitation. Size of the NPC samples were estimated and characterized by CPS Disc Centrifuge, Diffracted Light Scattering (DLS) and Field Emission Gun Scanning Electron Microscopy (FEG-SEM) techniques.

A Short Commentary of Nanotechnology on Traditional Chinese Medicine

Nanotechnology is the art of science manipulating matter at the nanoscale about 1 to 100 nanometers, 10-9 nm ranging from a sheet of paper (100,000 nanometers thick) to a human hair (around 80,000-100,000 nanometers).

Biological and Non-Conventional Synthesis of Zinc Oxide Nanoparticles (ZnO-NPs): Their Potential Applications

In nature, nanoparticles can be found as natural or synthetic. Nanoparticles may form either physically or chemically. Nanoparticles are uniform types of common material whose dimensions are less than 100 nm. Volcanic ash, ocean spray, fine sand, and dust are some examples of natural nanoparticles.

Electrochemical Supercapacitors Based on Hydrous RuO2/oxidized Multi-walled Carbon Nanotube Composites

Electrochemical properties of ruthenium oxide (RuO2)/oxidized multi-walled carbon nanotube (MWCNT) (RuO2/MWCNT) composite electrodes in supercapacitors were investigated. The electrodes were prepared by impregnating MWCNTs with different concentrations of RuCl3•xH2O solution, followed by chemical reduction and annealing at 150°C under a nitrogen atmosphere.
