Profile
The University of California, San Diego (also referred to as UC San Diego or UCSD) is a public research university located in La Jolla, California. UCSD is the seventh oldest of the ten University of California campuses and offers over 200 undergraduate and graduate degree programs, enrolling about 22,700 undergraduate and 6,300 graduate students. Institutional rankings of UC San Diego have commonly ranked the university very highly. For example, ScienceWatch ranks UCSD 7th of federally funded U.S. universities, based on the citation impact of their published research. UCSD established the Department of NanoEngineering within its Jacobs School of Engineering effective 2007. This sixth department will cover a broad range of topics, but focus particularly on biomedical nanotechnology, nanotechnologies for energy conversion, computational nanotechnology, and molecular and nanomaterials. The Department of NanoEngineering's educational program will develop in phases, with plans to reach a steady state of approximately 20 faculty members and an enrollment of 400 undergraduate students and 120 graduate students.

Expandable Foam for 3D Printing Large Objects

It's a frustrating limitation of 3D printing: Printed objects must be smaller than the machine making them. Huge machines are impractical for printing large parts because they take up too much space and require excessive time to print. Now, a new material can be used to 3D print small objects that expand upon heating. The foam could find applications in architecture, aerospace and biomedicine.

New Chip Wakes Up Small Wireless Devices, Could Extend Battery Life

A new power saving chip developed by engineers could significantly reduce or eliminate the need to replace batteries in Internet of Things devices and wearables. The so-called wake-up receiver wakes up a device only when it needs to communicate and perform its function. It allows the device to stay dormant the rest of the time and reduce power use.

Shape-shifting robots built from 'smarticles'

Building conventional robots typically requires carefully combining components like motors, batteries, actuators, body segments, legs and wheels. Now, researchers have taken a new approach, building a robot entirely from smaller robots known as "smarticles" to unlock the principles of a potentially new locomotion technique.
