UV Light-Modulated Fluctuation-Enhanced Gas Sensing by Layers of Graphene Flakes/TiO2 Nanoparticles
TL;DR: It is concluded that UV light activates the gas-sensing layer and improves gas detection at low concentrations of NO2, and the modulated sensor can replace an array of independent resistive sensors which would consume much more energy for heating.

Zero and negative energy dissipation at information-theoretic erasure
TL;DR: In this article, the authors introduce information-theoretic erasure based on Shannon's binary channel formula, which is a natural energy-dissipation-free way in which information is lost in double-potential-well memories.
Journal ArticleDOI
Do electromagnetic waves exist in a short cable at low frequencies? What does physics say?
TL;DR: In this paper, the authors show that the GAA scheme violates not only the wave equation but also the Second Law of Thermodynamics, the Principle of Detailed Balance, Boltzmann's Energy Equipartition Theorem, and Planck's formula by implying infinitely strong blackbody radiation.

Zero and negative energy dissipation at information-theoretic erasure
TL;DR: A new non-volatile, charge-based memory scheme wherein the erasure can be associated with even negative energy dissipation; this implies that the memory’s environment is cooled during information erasure and contradicts Landauer's principle of erasure dissipation.
