Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules
Advanced Functional Materials, EarlyView.A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Series SEPIC implementing voltage-lift technique for DC–DC power conversion
IET Power Electronics, 2008 The voltage-lift technique is an effective method that could be applied in electronic circuit design. A set of positive output DC-DC converters applying series SEPIC implementing voltage-lift techniques is introduced. Compared with the prototype of the SEPIC converter, these converters can perform positive to positive DC-DC voltage increasing ...

Advanced control methods and topologies for DC-DC power conversion [PDF]
, 2019 The investigation in this thesis begins with modeling and control of high-order DC-DC converters. Generalized state-space modeling, especially reduced-order state-space modeling method, is used to design suitable controllers for advanced DC-DC converters. An improved Sliding Mode (SM) controller is proposed for advanced DC-DC converters.

Advanced Functional Materials, EarlyView.The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of
