Palladium Membranes Separate Hydrogen

Compared to conventional technology, palladium membranes offer an increased flow of high-purity hydrogen from a gaseous stream. The membranes are prepared by electroless- deposition plating of Pd (or Pd alloy) on a porous support. The process results in a unique hexagonal structure. High flux translates to...

Software Recognizes Amblyopia in Early Childhood

In developed societies, amblyopia (i.e. lazy eye) is a leading cause of permanent vision loss under the age of 30. A research team implemented an electrophysiological method that recognizes the presence or lack of binocularity in children as young as six months of age. The method is also capable...

Better Foam Generation

Foam is a key indicator of efficacy and performance for a range of consumer pharmaceutical and food products. A company seeks cost-effective physical and mechanical technologies for enhanced foam generation and stability. Devices that are able to generate a high volume of foam from low-concentration, surfactant-based...
