By inserting a metamaterial sample on the floor of an object, the College of Minnesota researchers have been in a position to make use of sound to steer it in a sure path with out bodily touching it. Credit score: Olivia Hultgren

This contactless manipulation methodology has potential functions in industries together with robotics and manufacturing.

A staff of researchers on the College of Minnesota Twin Cities has uncovered a option to manipulate objects utilizing ultrasound waves, paving the best way for contactless motion in industries like manufacturing and robotics with out the necessity for an inside energy supply.

The world’s first expertise for consecutively manufacturing epsilon iron oxide that may take in millimeter waves with a excessive coercive pressure equal to that of neodymium magnets has been developed by a analysis group.

KIMS developed the world’s first steady manufacturing expertise for millimeter wave-absorbing magnetic supplies.

A analysis group led by Dr. Youn-kyoung Baek and Dr. Jung-goo Lee succeeded in creating the world’s first expertise to consecutively manufacture epsilon iron oxide that may take in millimeter wave with a excessive coercive pressure equal to that of neodymium (Nd) magnets. The researchers are within the Division of Magnetic Supplies in

Adventures in Nanotech: Rising a Metallic Snowflake

Scientists working on the degree of atoms are manipulating metals, opening up potentialities for creating new supplies.

Working on the degree of atoms, scientists in New Zealand and Australia created one thing surprising: tiny metallic snowflakes.

Why’s that vital? As a result of coaxing particular person atoms to cooperate is resulting in a revolution in engineering and know-how by way of nanomaterials. (And creating snowflakes is cool.)

Nanoscale buildings (a nanometer is one billionth of a meter or about 50,000

A global group led by UCLA researchers has developed a means to make use of perovskite in photo voltaic cells whereas defending it from the situations that trigger it to deteriorate. Credit score: Yang Lab/UCLA

Utilizing enhanced halide perovskite instead of silicon may produce cheaper units that rise up higher to mild, warmth.

Amid the entire efforts to transform the nation’s power provide to renewable sources, solar energy nonetheless accounts for rather less than 3% of electrical energy generated within the U.S. Partially, that’s due to the comparatively excessive price to provide photo voltaic cells.

One approach to decrease the
