Expandable foam for 3-D printing large objects

It's a frustrating limitation of 3-D printing: Printed objects must be smaller than the machine making them. Huge machines are impractical for printing large parts because they take up too much space and require excessive ...

'Kinks' in tiny chains reveal Brownian rotation

(PhysOrg.com) -- Rice University researchers have created a method to measure the axial rotation of tiny rods. The technique detailed in a paper by Sibani Lisa Biswal and her colleagues appears this month in the journal Physical ...

Research tests which nano system works best cancer treatment

(Phys.org) —In current research related to improving cancer treatments, one promising area of research is the effort to find ways to selectively pinpoint and target cancer cells while minimizing effects on healthy cells.

Waste silicon gets new life in lithium-ion batteries

Researchers at Rice University and the Université catholique de Louvain, Belgium, have developed a way to make flexible components for rechargeable lithium-ion (LI) batteries from discarded silicon.

Ironing out the causes of wrinkles

As a sign of aging or in a suit, wrinkles are almost never welcome, but two papers in the current issue of Physical Review Letters offer some perspective on what determines their size and shape in soft materials.

Novel, low-cost metal-forming process using a magnetic field

European scientists developed a novel foundry process using moulds formed by 'binding' metallic particles with application of a magnetic field. The process produced high-quality, complex parts at a very competitive cost.

New technique allows low-cost creation of 3-D nanostructures

Researchers from North Carolina State University have developed a new lithography technique that uses nanoscale spheres to create three-dimensional (3-D) structures with biomedical, electronic and photonic applications. The ...
