Dilute-metal-alloy nanoparticles exhibit enhanced catalytic performance compared with monometallic nanoparticles for many reactions. Anecdotal reports indicate that very dilute alloying can also slow the sintering rates of supported nanoparticles, although this has not been rigorously assessed and cannot be explained using bulk descriptors such as metal melting temperature. Here we utilize methanol synthesis reactivity, microscopy and in situ spectroscopy measurements to demonstrate that 1 atom%...

Vulcanized rubbers, essential in tires and many other elastomers, are exceptionally difficult to recycle because their sulfur-cross-linked, additive-rich networks resist chemical degradation. This high resistance has created a mounting environmental burden, yet strategies that operate under mild and nontoxic-gas-emitting conditions while producing valuable products remain scarce. Here we report a mild, one-step oxidative approach that selectively cleaves backbone C═C bonds in both thermoplastic...

Phthalocyanine (Pc)-based molecular thin films have emerged in recent years as a promising class of organic semiconductor materials for optoelectronic applications owing to their long exciton coherence length and fast exciton diffusion. However, the dependence of their exciton properties on the dimensionality and thermodynamic conditions, presence of metal ions, and effects of chemical modifications to the PC systems is not yet fully understood. As a first step towards a more comprehensive...
