Research team identifies culprit behind canned wine's rotten egg smell

While it is the fastest growing sector of the wine-packaging market, canned wine faces a few hurdles. It's not considered as elegant as wine in a bottle, and it's not as popular as the formerly maligned "wine bag in a box." ...

Study demonstrates spontaneous self-organization of microdroplets through quasi one-dimensional confinement

Polymer systems composed of multiple components can spontaneously induce emulsion or microdroplets by mechanical mixing, as an intermediate state of macroscopic phase separation. Unfortunately, the size of generated droplets ...

Scientists develop tunable colored films for displays and sensors

Researchers at the Indian Institute of Science (IISc) have developed flexible films that exhibit bright colors purely by virtue of their physical structure, without the need for any pigment. When stretched, the films exhibit ...

Study finds chemodiversity of soil-dissolved organic matter altered by microplastics

Soil is the largest reservoir of microplastic (MP), with the corresponding content being 4 to 23 times that in oceans. Plastics are widely used in production and daily life due to their low cost, good ductility and durability. ...

Using molecular 'cookie cutters' to view membrane protein organization

The membrane that encases a biological cell is not simply a barrier; it is chock full of proteins involved in all sorts of critical biological functions. To really understand what membrane proteins are doing and how, researchers ...
