Kyung-Suk Kim and Mazen Diab have worked out the mathematics of how wrinkles form in solid materials under compression — and how, under more compression, those wrinkles can become creases. The mathematics of wrinkles and creases could help in the design of flexible electronic circuits, artificial skin, and soft robotic grips and may help explain brain injuries due to compression.

PROVIDENCE, R.I. [Brown University] — Wrinkles, creases and folds are everywhere in nature, from the surface of human skin to the buckled crust of the Earth. They can also be useful structures for engineers. Wrinkles in thin films, for example, can help make durable circuit boards for flexible electronics. (more…)

UCLA researchers capture wasted heat, use it to power devices

FINDINGS:

Imagine how much you could save on your electricity bill if you could use the excess heat your computer generates to actually power the machine.

Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have taken an important step toward harnessing that heat and converting it for practical use. The advance could lead to more energy-efficient appliances and information processing devices. (more…)

Purpose and Uses of the Relay Board for Electronics Hobbyists and Enthusiasts

A relayboard is effectively a board containing one or more relay switches. A relay switch is often used to switch a large amount of power on for a small operating energy; or to turn specific circuits on and off within an application.

Often the relay becomes the breaker point between a low and high voltage, or a low and high current, part of an application. The most obvious version of this usage is the RCD board used to insulate your home against electrical surges. The trip switches on the board are all relays – in effect making the RCD (otherwise known as a residual current device) one of the largest and most obvious relay boards in the country. (more…)

Natural birth — but not C-section — triggers brain boosting proteins

Vaginal birth triggers the expression of a protein in the brains of newborns that improves brain development and function in adulthood, according to a new study by Yale School of Medicine researchers, who also found that this protein expression is impaired in the brains of offspring delivered by caesarean section (C-sections).

These findings are published in the August issue of PLoS ONE by a team of researchers led by Tamas Horvath, the Jean and David W. Wallace Professor of Biomedical Research and chair of the Department of Comparative Medicine at Yale School of Medicine. (more…)
