Enhancing their inherent properties by adding functional

Imagine if you could know the status of any molecule in your body without needing to get your blood drawn. Science fiction? Almost – but researchers at the University of Arizona are working on ways to do this by measuring molecules in sweat. When physicians take blood samples from patients, they send the samples to

Munich-based scientists have now investigated the molecular

Researchers at the National Institute of Standards and Technology (NIST) have found a way to link measurements made by a device integral to microchip fabrication and other industries directly to the recently redefined International System of Units (SI, the modern metric system). That traceability can greatly increase users’ confidence in their measurements because the SI

By creating neatly spaced slits in a clay mineral, University of Groningen Professor of Experimental Solid State Physics Petra Rudolf was able to filter water to remove a toxic herbicide. After removing the pollutant by heating the material, the

In many industrial processes, such as in bioreactors that produce fuels or pharmaceuticals, foam can get in the way. Frothy bubbles can take up a lot of space, limiting the volume available for making the product and sometimes gumming up pipes and valves or damaging living cells. Companies spend an estimated $3 billion a year

Because they are so tiny, they easily enter into the cells

WASHINGTON, Feb. 11, 2020 — Journalists who register for the American Chemical Society’s (ACS’) Spring 2020 National Meeting & Exposition in Philadelphia will have access to more than 14,000 presentations on topics such as food, nutrition, medicine, health, nanotechnology, space science, energy and the environment. The meeting will be held March 22 to 26 in

A new, battery-free sensor can detect water leaks in buildings at a fraction of the cost of existing systems. The tiny device, developed by researchers at the University of Waterloo, uses nanotechnology to power itself and send an alert to smartphones when exposed to moisture. By eliminating a battery and related circuitry, researchers estimate their

This can explain why and under which conditions heat propagation becomes fluid-like rather than diffusive. Their equations will make it easier

Therapeutic cancer vaccines were first developed 100 years ago and have remained broadly ineffective to date. Before tangible results can be achieved, two major obstacles must be overcome. Firstly, since tumor mutations are unique to each patient, cancer cell antigens must be targeted extremely precisely, which is very hard to achieve. Secondly, a safe system

Quantum engineers from UNSW Sydney have created artificial atoms in silicon chips that offer improved stability for quantum computing. In a paper published today in Nature Communications, UNSW quantum computing researchers describe how they created artificial atoms in a silicon ‘quantum dot’, a tiny space in a quantum circuit where electrons are used as qubits
