Harmful dyes in lakes, rivers can become colorless with new, sponge-like material

Scientists have created an environmentally friendly way to remove color from dyes in water in a matter of seconds.

Advanced microscopy technique reveals new aspects of water at the nanoscale level

A new microscopy technique allows researchers to visualize liquids at the nanoscale level -- about 10 times more resolution than with traditional transmission electron microscopy -- for the first time.

New competition for MOFs: Scientists make stronger COFs

Researchers find a way to better 'weld' covalent organic frameworks together.

Researchers develop 'tornado' lab-on-a-chip technology with micro tweezers to detect dangerous viruses, biological contaminants

Researchers have developed a new class of optical nanotweezers that can trap and detect biomolecules, viruses and DNA more rapidly. The technology can also use light to promptly detect cancer or improve the production of medications.

Fast, cheap and colorful 3D printing with nanomaterials

Researchers have tweaked 3D-printing so it can print in all of the colors of the rainbow.

Researchers disclose optical secrets of disulfide nanotubes

The team demonstrates a strong light-matter interaction in suspensions and self-assembled films of tungsten disulfide nanotubes.

Scientists discover a first-of-its-kind material for the quantum age

A physicist has discovered a new material that has the potential to become a building block in the new era of quantum materials, those that are composed of microscopically condensed matter and expected to change our development of technology.

An elastic puff of air

Superflexible aerogels are highly efficient absorbents, thermal insulators, and pressure sensors.

Insight into catalysis through novel study of X-ray absorption spectroscopy

An international team has succeeded in investigating electronic states of a transition metal in detail and drawing reliable conclusions on their catalytic effect from the data. These results are helpful for the development of future applications of catalytic transition-metal systems.

Insight into loss processes in perovskite solar cells enables efficiency improvements

In perovskite solar cells, charge carriers are mainly lost through recombination occurring at interface defect sites. In contrast, recombination at defect sites within the perovskite layer does not limit the performance of the solar cells at present.

Scientists find holes in light by tying it in knots

Physicists have found a new way of evaluating how light flows through space - by tying knots in it.

Fire-resistant polymer nanocontainers

Polymers play an essential role in our daily lives, but they also come with an increased risk of fire. Efficient flame retardants are key to ensuring the safety of humans and safeguarding goods from the dangers of accidental fires.

On-chip optical filter processes wide range of light wavelengths

Silicon-based system offers smaller, cheaper alternative to other ?broadband? filters; could improve a variety of photonic devices.

Sunscreen for dancing molecules

This study is the first to use heavy water in the field of transmission electron microscopy (TEM). This approach significantly delays sample damage, which is one of the major impediments for broader application of liquid-phase TEM to fragile biological samples.

New type of nanoparticle for drug delivery lasts longer in bloodstream

Selecting the right packaging to get precious cargo from point A to point B can be a daunting task at the post office. For some time, scientists have wrestled with a similar set of questions when packaging medicine for delivery in the bloodstream: How much packing will keep it safe? Is it the right packing material? Is it too big? Is it too heavy?

Microscopic antennas to peer into nano-sized worlds

Affordable and highly sensitive infrared detectors could revolutionise molecular sensing.
