The key feature of spintronic devices is their ability to use spin currents to transfer momentum, enabling low-energy, ...

A cook's reaction to cockroaches in the kitchen is a good approximation of a physicist's reaction to friction: not only is it undesirable, it is hard to get rid of. OK, our analogy falls at a last ...

“Oxidation can deteriorate the properties of copper that are critical for its use, particularly in the semiconductor industry and electro-optics applications. This has prompted numerous studies ...

In a hypertorus model of the Universe, motion in a straight line will return you to your original location, even in an uncurved (flat) spacetime. The Universe could also be closed and positively ...

Is Mk really flat? Thomas Nugent, CC BY-SA 2.0. From where I am sitting, the earth is flat. The floor that runs the length of the unit my hackerspace sits in is flat, the concrete apron behind it on ...

Textbook formulas for describing heat flow characteristics, crucial in many industries, are oversimplified, study shows. Whether it's water flowing across a condenser plate in an industrial plant, or ...

Flat design was previously the final aesthetic: clean, bright, and sublimely simple. No shadows, no mess - simply shapes and colours. At some point though, we found ourselves missing the warmth. The ...

A necessary and sufficient condition is given for a nontrivial homology class of a simply connected 4-manifold to be represented by a simple, topologically locally flat embedding of a compact Riemann ...
