Tiny Transformers: Chemists create Microscopic and Malleable Building Blocks

A team of NYU chemists has created malleable and microscopic self-assembling particles that can serve as the next generation of building blocks in the creation of synthetic materials. The research focused on engineering particles a micrometer in width -- about 1/200th the width of a strand of human hair (on which the particles [pink and blue] are placed in the above image).

Scientists found a Molecule that will help to make organic electronic devices. A derivative of [3]-radialene, a molecule known to the science for nearly 30 years, can be used to create organic semiconductors. Dmitry Ivanov, Moscow State University, believes the achievement will greatly contribute to the development of organic electronics and, in particular, to fabrication of organic LEDs and new classes of organic solar cells.

Organic or “plastic” electronics is a relatively young scientific field, which came to life about 15-20 years ago...

‘Green’ Electronic Materials Produced with Synthetic Biology

Synthetic biowire are making an electrical connection between two electrodes. Researchers led by microbiologist Derek Lovely at UMass Amherst say the wires, which rival the thinnest wires known to man, are produced from renewable, inexpensive feedstocks and avoid the harsh chemical processes typically used to produce nanoelectronic materials.

A genetically designed strain of bacteria spins out very thin and highly conductive wires made up of solely of non-toxic, natural amino acids. Researchers led by microbiologist Derek Lovely say the wires, which rival the thinnest wires known to man, are produced from renewable, inexpensive feedstocks and avoid the harsh chemical processes typically used to produce nanoelectronic materials...

Luminescent Compounds developed that Change Emission Colors on Mechanical Stimuli

In mechanochromism, certain solid and liquid crystalline materials change their photoluminescence properties upon mechanical stimulation, such as grinding, ball-milling and crushing. Although such compounds have attracted much attention with hopes of various applications, it has heretofore been thought difficult to synthesize mechanochromic compounds with desired emission properties and behaviors as each molecule emits different color.
