For years, materials have been made at the nanoscale level to take advantage of their mechanical, optical, and energy properties, but efforts to scale these materials to larger sizes have resulted in diminished performance and structural integrity. Now, researchers describe a new process to create lightweight, strong and super elastic 3D printed metallic nanostructured materials with unprecedented scalability, 7 orders of magnitude control of arbitrary 3D architectures.

Strikingly, these multiscale metallic materials have displayed super elasticity because of their design...

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...

Controlling Spatial Heat and Light Distribution by Using Photothermal Enhancing Auto-Regulated Liposomes (PEARLs).

Dr. Gang Zheng and a team of biomedical researchers have discovered a “smart” organic, biodegradable nanoparticle that uses heat and light in a controlled manner to potentially target and ablate tumours with greater precision. The proof-of-concept findings provide a viable approach to boosting the clinical utility of photo-thermal therapy in treating cancer, says Dr. Zheng, Senior Scientist at the Princess Margaret and Professor of Medical Biophysics at the University of Toronto.He talks about and demonstrates the research at https://youtu.be/EEN6Mz5iWBI.

In the lab, using phantom models, the “smart” nanoparticle the team has dubbed PEARLs – photo-thermal enhancing auto-regula...
