Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Laser-Induced Breakdown Spectroscopy & Enrichment by Chelation
Procedia Engineering, 2012 AbstractLIBS is used for fast, multi-component analysis of element compositions, but it is not very suitable for liquids. Moreover the sensitivity for metal ions is often insufficient. A fast and sensitive detection tool for metal ions in food matrices, including aqueous solutions, is developed. The principle of operation of LIBS is that a small amount

Laser-induced breakdown spectroscopy of cyanobacteria in carbonate matrices under simulated Martian environment [PDF]
, 2021 The finding on the Martian surface of hydrated salt minerals, like carbonates and sulphates, and their interpretation as deriving from the desiccation of old bodies of water, has provided an evidence of liquid water activity on the surface of Mars [1 ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
Advanced Functional Materials, EarlyView.We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
