Generally it is believed that core quantum dots (QDs) are good reducing agents and are used for that purpose in solar hydrogen generation and various organic transformations. However, core QDs are very unstable. Core/shell dots are more robust, but the shell minimizes redox activity. Researchers now demonstrate that this isn't perfectly true. In fact, they found that certain core/shell materials are a better reducing agent than the core alone. Most importantly, core/shell QDs are substantially more robust than the core alone.

A new project has been set up to develop an immunologic-based treatment strategy where cancer cells are reprogrammed to become 'visible' to the patient's immune system.
Scientists reveal a phenomenon that is 'radically different from textbook physics' and this work has led to the discovery and characterisation of a new family of quasiparticles found in graphene-based materials. Called Brown-Zak fermions these extraordinary particles have the potential to achieve the Holy Grail of 2D materials by having ultra-high frequency transistors which can in turn produce a new generation of superfast electronic devices.
Researchers have demonstrated light transport-assisted information processing by creating a pearl spectrometer.
