The Demetriades - Tsafka - Kokkalis Prizes are awarded annually to PhD candidates selected for the best thesis, publication, or discovery in select fields. Saransh Sharma, advised by Professor Azita Emami, has received the prize in Biotechnology or Related Fields for his research in developing ultra-low power and highly miniaturized medical electronics for in-vivo localization and tracking. Nathaniel Wei, advised by Professor John Dabiri, has received the prize in Environmentally Benign Renewable Energy Sources or Related Fields for his research that explores the ways in which unsteady flows in the atmosphere can be leveraged in wind-energy systems for enhanced performance, robustness, and operational longevity. Rebecca Gallivan, advised by Professor Julia Greer, has received the prize in Nanotechnology or Related Fields. Coupled with the development of novel materials processing, Gallivan's research focuses on uncovering fundamental insight into the relationship between length-scale and microstructural features on nanomechanical phenomena in order to lay the foundation for advanced engineering and complex design of materials in nanotechnologies.

In the latest advance in nano- and micro-architected materials, engineers at Caltech have developed a new material made from numerous interconnected microscale knots. The knots make the material far tougher than identically structured but unknotted materials: they absorb more energy and are able to deform more while still being able to return to their original shape undamaged.

Engineers at Caltech have developed a method for 3-D printing pure and multicomponent metals, at a resolution that is, in some cases, an order of magnitude smaller than previously possible. "We had to develop a new way of doing it, and we couldn't rely on heat to build our structures," says Max Saccone. [Caltech story]

Caltech has been doing interesting work in 3D printing for a number of years now, especially Professor Julia Greer and the Greer Group. The team works in hierarchical, nano, battery and other new materials, as well as processes for 3D printing. One novel area that the team have been doing exploring over the years is related to hydrogel derived materials. [Read full story]

Once considered science fiction, technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of Caltech researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed—including to places that currently have no access to reliable power. "This is an extraordinary and unprecedented project," says Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance. "It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world." [Caltech story]

A new artificial skin can now give robots the ability to sense temperature, pressure, and even toxic chemicals through a simple touch. The multimodal robotic-sensing platform, dubbed M-Bot, was developed in the lab of Wei Gao, Assistant Professor of Medical Engineering; Investigator, Heritage Medical Research Institute; Ronald and JoAnne Willens Scholar. It aims to give humans more precise control over robots while also protecting the humans from potential hazards. "I think we have shown a proof of concept," says Gao. "But we want to improve the stability of this robotic skin to make it last longer. By optimizing new inks and new materials, we hope this can be used for different kinds of targeted detections. We want to put it on more powerful robots and make them smarter, more intelligent." [Caltech story]

The course combines topical lectures that give the students a preview of what they will be doing in the cleanroom along with hands-on practical training. Both components are conducted as a team effort between Scherer and the KNI technical staff. The first two lectures of the term were presented by KNI’s microscopist, Dr. Annalena Wolff, who lectured on scanning electron and focused ion beam microscopy. Additional lectures were presented by KNI’s Associate Director of Technical Operations, Dr. Guy DeRose, on electron beam lithography.
