Using Laser Metal Printing to Cool Computer Chips

Traditionally, electronics are cooled using a heat sink that transfers the heat generated by the electronic system into the air or a liquid coolant. For the heat sink to work, it has to be attached to the CPU or the graphics processor via a thermal interface material such as thermal paste. It...

Typical butterfly valves cannot seal at both ambient and cryogenic temperatures. At cryogenic temperatures, valves grow and shrink, changing critical dimensions such as distance between the disc and seat....

Design Software Identifies a Product's Performance Tradeoffs

Designing any product — from complex car parts to wrenches — is a balancing act with conflicting performance tradeoffs. Making something lightweight, for instance, may compromise its durability.

Over the past decade, many researchers have been working on small, portable diagnostic devices based on chemical reactions that occur on paper strips. Many of these tests make use of...

Wearable devices have been limited to sensing signals either on the surface of the skin or right beneath it. A new wearable ultrasound patch non-invasively monitors blood pressure in arteries...

Double-Fed Induction Linear Alternator

This technology was developed to address the limitations of traditional, single-fed linear alternators that require permanent magnets, adhesive bonding organics, and heavy iron laminations for flux control. They experience eddy-current losses and require electromagnetic interference protection. Furthermore,...

Battery Electrolyte Doubles Driving Range for Electric Vehicles

Conventional electrolytes used in lithium-ion batteries that power household electronics like computers and cellphones are not suitable for lithium-metal batteries. Lithium-metal batteries that replace a graphite electrode with a lithium electrode are the holy grail of energy...

Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...

The connection of plastics and metals poses a challenge due to the different physical properties of the two materials. All conventional joining options, such as bonds using adhesives or rivets,...
