Bioinspired phototransistor with tunable sensitivity for low-contrast target detection

Light: Science & Applications
Accurate recognition of low-contrast targets in complex visual environments is essential for advanced intelligent machine vision systems. Conventional photodetectors often suffer from a weak photoresponse and a linear dependence of photocurrent on light ...

Sustainable metals: integrating science and systems approaches

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
This article introduces a special issue of the transactions arising from a Royal Society Discussion Meeting on ‘sustainable metals’. Recognizing that progress to date toward the goals of ‘sustainability’ has been limited, the meeting aimed to open up a new level of interdisciplinary dialogue, collaboration and discussion of disruptive approaches.

Metal chelation in separation science [PDF]

, 1994
The science o f transition metal chelation finds applicability in many analytical areas where the determination of agents which will chelate transition metal ions, or the determination of transition metal ions themselves, is desired. This thesis details the use of transition metal chelation in solving analytical problems encountered in the adhesives ...

Heavy metal et sciences sociales

Calenda, 2014
Les recherches en sciences sociales sur les genres musicaux que l’on peut rassembler sous les étiquettes de hard rock, heavy metal ou metal sont restées marginales jusqu’au début des années 2000. Elles sont cependant en voie de structuration depuis quelques années au niveau international, surtout dans les mondes anglophone et germanophone – via ...

Ferroelectric polarization and magnetic structure at domain walls in a multiferroic film

Nature Communications
Domain walls affect significantly ferroelectric and magnetic properties of magnetoelectric multiferroics. The stereotype is that the ferroelectric polarization will reduce at the domain walls due to the incomplete shielding of depolarization field or the
