New generation of flexible graphene transistors

Scientists have come up with a novel process for manufacturing transistors that combine flexibility and electron mobility and are capable of working at very high frequencies in the GHz range. The process uses a form of graphene in solution that is compatible with printing techniques. Electronic components such as these should lead to the development of high-performance electronic circuits built into everyday objects.

Microlens arrays from the test tube

Biomineralized tissues, such as sea shells and bones, grow in a genetically programmed way to obtain specific shapes and compositions, which define the unique functionalities. The growth of biominerals usually takes place in aqueous media at ambient conditions. Material scientists are keen to adapt this process from nature for a cost-efficient and simple fabrication of inorganic based materials.

Cold atoms simulate graphene

Scientists at ETH Zurich used a set of laser beams to create a honeycomb-like structure similar to that found in graphene. By loading ultracold atoms into this optical lattice, they can simulate electronic properties of this promising material. Such experiments may be used to identify electronic properties of materials which have yet to be discovered.

Molecular graphene heralds new era of 'designer electrons'

Researchers from Stanford University and the U.S. Department of Energy's SLAC National Accelerator Laboratory have created the first-ever system of 'designer electrons' - exotic variants of ordinary electrons with tunable properties that may ultimately lead to new types of materials and devices.

A new method for examining membrane proteins

Experiments at SLAC's Linac Coherent Light Source (LCLS) have shown a promising new way to collect data on these elusive proteins. Researchers embedded tiny protein crystals in an oily paste that mimics the supportive environment of the cell membrane, and then hit them with a powerful X-ray laser to determine the protein's structure.

Fighting cancer with nanotechnology - a roundtable discussion

Imagine a test that sifts through millions of molecules in a drop of a patient's blood to detect a telltale protein signature of a cancer subtype, or a drug ferry that doesn't release its toxic contents until it slips inside cancer cells. These and other nanotechnologies could be game changers in how we diagnose, monitor and treat cancer. To more fully understand the impact, The Kavli Foundation held a roundtable conference with four pioneers in the field.
