Advanced Electronic Materials, EarlyView.ABSTRACT Layered 2D materials are considered as promising for memristive applications due to their ultimate vertical scalability compared to conventional semiconductor films and pronounced hysteresis properties. Bias‐resolved Raman and Photoluminescence mapping is used to quantify strain from phonon shifts and carrier density from the exciton‐trion ...

Ultraclean coal production using froth flotation and acid leaching
Revista Facultad de Ingeniería Universidad de Antioquia, 2013 Ultraclean coals represent an important raw material to elaborate high value products such as carbon fiber, electrodes, carbon foam and so on. In this work, ultraclean coals having less than 0.50% (w/w, db) of ash and 1.00% q(w/w) of mineral matter were

Model‐Based Time‐Modulated Write Algorithm for 1R Analog Memristive Crossbar Arrays
Advanced Electronic Materials, EarlyView.A novel model‐based time‐modulated write algorithm efficiently programs analog 1R memristive crossbar arrays by varying pulse duration at a fixed voltage. By leveraging a physics‐based compact model and a dynamic gain mechanism, this approach overcomes device nonlinearities and parasitic effects.
