Using the ‘shadow-effect’ to generate electricity

Novel shadow-effect energy generator uses the contrast in illumination between the lit and shadowed areas

25-May-2020

Shadows are often associated with darkness and uncertainty. Now, researchers from the National University of Singapore (NUS) are giving shadows a positive spin by demonstrating a way to harness this common but often overlooked optical effect to generate electricity. This novel concept opens up ...

General descriptor sparks advancements in dye chemistry

Move away from inefficient trial-and-error developments to quantitatively design luminescent materials

19-May-2020

There is an ongoing demand in biological research to accelerate the development of fluorescent probes based on the photo-induced electron transfer (PET) mechanism. By modulating PET formations, these probes significantly change fluorescence intensities, allowing a convenient route to monitor ...

One-way roads for spin currents

24-May-2018

The spin is a type of angular momentum which is intrinsic to particles, grosso modo as if they were spinning on themselves. Particles can exchange their spin, and in this way spin currents can be formed in a material. Through years of research, scientists have learned how to control such spin ...

Microscale IR spectroscopy enabled by phase change materials and metasurfaces

16-May-2018

The mid-infrared is an interesting part of the electromagnetic spectrum that is composed of colours that cannot be seen by the human eye. Many chemical molecules resonate when illuminated by infrared light. This infrared resonance can then be used to identify or "fingerprint" the molecules. The ...

Scaling to new heights with gecko-inspired adhesive

12-Jan-2018

Some animals, such as geckos, can easily climb up walls and across ceilings. But currently, no material exists that allows everyday people to scale walls or transverse ceilings as effortlessly. Now, scientists report a dry adhesive that could someday make it easier to defy gravity. Geckos can ...
