Nanodiamond-Embedded Membrane Filters for 'Sparkling' Clean Water

Although most of the planet is covered by water, only a fraction of it is clean enough for humans to use. Therefore, it is important to recycle this resource whenever possible. Current purification techniques cannot adequately handle the very hot wastewater generated by some industries.

Silver-Doped Metal Nanocluster Shows 18-Fold Greater Photoluminescence

Scientists at Tokyo Institute of Technology have discovered that a silver-doped platinum thiolate nanometal complex shows 18-fold greater photoluminescence than the original platinum complex. In their recent paper, they provide insights into the causes of this, crowning a new approach to creating efficient non-toxic and biocompatible compounds for bioimaging.
