Hydrogels form tiny, water-filled pores with diameters so small that molecular-level studies can be difficult. Moreover, the motion of water molecules and dissolved ions is so fast that they are difficult to follow. Therefore, ...

The mantra 'reduce, reuse, recycle' is increasingly pertinent. Every year, vast amounts of energy that could be captured and reused are lost through waste heat. Now, A*STAR scientists have demonstrated, through theoretical ...

When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena such as optical tweezers, for which Arthur Ashkin ...

Chiral molecules are defined as molecules that are non-superimposable on their mirror images, much like that of left and right human hand bone structure. There are many examples of chiral molecules in nature, including proteins ...

It's easy to take a lot for granted. Scientists do this when they study stress, the force per unit area on an object. Scientists handle stress mathematically by assuming it to have symmetry. That means the components of stress ...
