Designer 'barrel' proteins created
Thu, 23 Oct 2014 14:23:10 EDT
Designer proteins that expand on nature's own repertoire, created by a team of chemists and biochemists, are described in a new paper. Proteins are long linear molecules that fold up to form well-defined 3D shapes. These 3D molecular architectures are essential for biological functions such as the elasticity of skin, the digestion of food, and the transport of oxygen in blood.
Molecular structure of water at gold electrodes revealed

Researchers have recorded the first observations of the molecular structure of liquid water at a gold electrode under different battery charging conditions.
First protein microfiber engineered: New material advances tissue engineering and drug delivery
Thu, 23 Oct 2014 11:10:52 EDT
Researchers have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. For the first time, this achievement has been realized on the microscale -- a leap of magnitude in size that presents significant new opportunities for using engineered protein fibers.
Waste, an alternative source of energy to petroleum
Thu, 23 Oct 2014 09:10:07 EDT
The development of sustainable refineries is the focus of recent research, where it is possible to produce fuels and raw materials providing an alternative to petroleum by using biomass and other waste materials like plastics, tires, etc. Conical spouted beds are the key to the high energy efficiency of these refineries.
