TL;DR: Organometal halide perovskite synaptic devices are fabricated; they emulate important working principles of a biological synapse, including excitatory postsynaptic current, paired-pulse facilitation, short-term plasticity, long-term Plasticity, and spike-timing dependent plasticity.

TL;DR: In this article, the influence of the austempering temperature, chemical composition and partitioning on the nanostructure and mechanical behavior of high carbon (0.71 wt.%) bainitic-austenitic transformation-induced plasticity (TRIP) steels by atom probe tomography was investigated.

TL;DR: In this paper, the authors synthesize gold nanoparticles synthesized with Frechet-type dendrons possessing a single thiol group at the focal point with average diameters of 2.4 ± 0.2 nm.

TL;DR: The Pd nanoparticles on CB-PN exhibit high stability and dispersibility in water as well as excellent catalytic activity and recyclability in carbon-carbon and carbon-nitrogen bond-forming reactions in aqueous medium suggesting potential applications as a green catalyst.

TL;DR: In this article, a low-temperature chemical vapor deposition method was proposed to mitigate defect formation in graphene by heterogeneous solid carbon sources containing a mixture of aromatic and aliphatic carbon on a Cu substrate.
