• Lawrence Livermore scientists discover new materials to capture methane

  Scientists at Lawrence Livermore National Laboratory (LLNL) and UC Berkeley and have discovered new materials to capture methane, the second highest concentration greenhouse gas emitted into the atmosphere. Methane is a substantial driver of global climate change, contributing 30 percent of current more

• Could zeolites make cigarettes safer to smoke?

  A self-protecting zeolite catalyst that degrades the carcinogens in cigarette smoke has been reported by scientists. The zeolite – which is prepared in a one-step hydrothermal crystallisation without any post treatment or shape direction – selectively breaks down tobacco specific nitrosamines (TSNA) more

• Zeolites for efficient oil-water separation

  Scientists in China have used zeolite-coated mesh films for gravity-driven oil-water separation. The superhydrophilicity and underwater superoleophobicity of the zeolite’s surface allow the highly efficient separation of various oils. Unlike other oil-water separation membranes based on superhydroph more

• Materials, Vol. 6, Pages 2074-2089: Synthesis of Zeolites Na-P1 from South African Coal Fly Ash: Effect of Impeller Design and Agitation

  South African fly ash has been shown to be a useful feedstock for the synthesis of some zeolites. The present study focuses on the effect of impeller design and agitation rates on the synthesis of zeolite Na-P1 which are critical to the commercialization of this product. The effects of three impelle more

• Hydrophobic High Surface Area Zeolites Derived from Fly Ash for Oil Spill Remediation

  Fly ash, a coal combustion byproduct with a predominantly aluminosilicate composition, is modified to develop an inexpensive sorbent for oil spill remediation. The as-produced fly ash is a hydrophilic material with poor sorption capacity. A simple two-step chemical modification process is designed t more
