Two‐Dimensional Reconfigurable Photodiode for In‐Sensor Color Filtering and Spectral Logic

Advanced Materials, EarlyView.
By harnessing the photodoping of different aggregates, the device exhibits wavelength‐dependent volatile‐to‐nonvolatile photoresponses that can be reconfigured via bias modulation. This enables in‐sensor color filtering and spectral‐encrypted information processing, eliminating reliance on external optical filters or post‐processing algorithms ...

Intrinsic Coordination Architecture Governing Selectivity Divergence Between Extended and Single‐Site Electrocatalysts

Advanced Materials, EarlyView.
Catalyst coordination acts as a loaded dice biasing reaction selectivity. Single‐atom site catalysts lock intermediates in exposed configurations, enabling continued hydrogenation and favoring oxygen‐retaining products. In contrast, extended metal surfaces fully coordinate and shield reactive centers, promoting deoxygenation pathways. This work reveals

A Formal Design Method

Acta Polytechnica, 2000
In the first part of this article, there are described two ways out of the design process theory: metamodel as a basic principle of a design process description and non-standard logics as a feasible formal background of the design theory.

Energy Band Alignment and Electro‐Optical Behavior of Nearly Unstrained Monolayer MoS2 Heterostructures With GaN

Advanced Materials Interfaces, EarlyView.
Large size (∼100 µm) monolayer MoS2 grown by LPI‐CVD on n‐GaN exhibit a high n‐type doping, very low strain, and a type‐I band alignment at MoS2/GaN interface. Photocurrent measurements under illumination with photon energies from ∼2 to ∼5 eV show superior electro‐optical performances of these MoS2/n‐GaN heterojunctions as compared to Ni/n‐GaN devices ...

An RTL-Based General Synthesis Methodology for Device-Independent Ternary Logic Circuits

IEEE Access
Ternary logic circuits are considered a high-potential alternative that can continue the technological advance of binary logic. Current studies in ternary logic focus on two aspects: One focuses on designing specific ternary circuits (such as adders ...

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

Advanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

3D Printed Multimaterial Microfluidic Transistors

Advanced Materials Technologies, EarlyView.
We introduce a biocompatible, high resolution photopolymer resin that closely mimics the Young's Modulus (elasticity) and reversible stretchability (no hysteresis) of poly(dimethylsiloxane) (PDMS), enabling the fabrication of microfluidic transistors (i.e., microvalves capable of proportional amplification) by multimaterial stereolithography (mSLA ...

Indistinguishability in controlled query evaluation over prioritized description logic ontologies

Web Semantics
In this paper we study Controlled Query Evaluation (CQE), a declarative approach to privacy-preserving query answering over databases, knowledge bases, and ontologies. CQE is based on the notion of censor, which defines the answers to each query posed to
