Making polymer nanostructures from a greenhouse gas

Scientists have introduced a two-step, one-pot conversion of CO2 and epoxides to polycarbonate block copolymers that contain both water-soluble and hydrophobic regions and can aggregate into nanoparticles or micelles.

A new type of modulator for the future of data transmission

Researchers present a novel modulator that is a hundred times smaller and that can, therefore, be easily integrated into electronic circuits. Moreover, the new modulator is considerably cheaper and faster than common models, and it uses far less energy.

Magnetic material unnecessary to create spin current

Researchers that you don't need a magnetic material to create spin current from insulators. This discovery has important implications for the field of spintronics and the development of high-speed, low-power electronics that use electron spin rather than charge to carry information.

3D 'printouts' at the nanoscale using self-assembling DNA structures

The new technique makes it possible to synthesize 3D DNA origami structures that are also able to tolerate the low salt concentrations inside the body, which opens the way for completely new biological applications of DNA nanotechnology. The design process is also highly automated, which enables the creation of synthetic DNA nanostructures of remarkable complexity.

Acetic acid as a proton shuttle in gold chemistry

A recently published study gives a vivid example of unusual chemical reactivity found in the reactions with organogold complexes. Using the complex of modern physical methods joined with computational studies, the authors proposed reaction mechanism, where a molecule of acetic acid serves as a proton shuttle, transferring the hydrogen atom between the reaction centers.

Illuminating the electronic properties of graphene

Researchers have shown that both the carrier mobility and the carrier density of graphene can be measured in a spatially resolved and non-destructive way - providing 'maps' of the electronic properties critical for the successful use of graphene in photovoltaics, electronics, spintronics and optics - using terahertz radiation and doing away with the need to fabricate devices.
