Dynamic Interfacial Charge Regulation for High‐Fidelity Broadband Circularly Polarized Light Detection

open access: yesAdvanced Science, EarlyView.
A photoelectrochemical circularly polarized light detector combines a multilayer chiral photonic film with a dynamically regulated BiVO4‐RGO‐MXene transducer. Broadband optical modulation from 360 to 830 nm is converted into stable electrical outputs through low‐noise solid‐liquid interfacial charge transfer, enabling self‐powered CPL discrimination ...

Weather Attention in Online Discourse and Price Uncertainty in Agricultural Futures Markets

open access: yesAgribusiness, EarlyView.
ABSTRACT Weather is a central determinant of production risk in agricultural markets, but markets respond not only to weather conditions themselves, but also to how those conditions are noticed, framed, and interpreted in public discourse. In this setting, real‐time online weather discussions may shape price uncertainty by influencing how market ...

A Low-Input Current Chopper Amplifier

open access: yes, 2012
This thesis describes the implementation of a low input-current chopper amplifier. Chopper amplifiers are attractive in applications where high DC precision is required, due to their low offset, drift & 1/f noise.

A 36μW rail-to-rail-input chopper stabilized amplifier using correlated double sampling

open access: yes, 2013
This paper describes a chopper stabilized amplifier, obtained using an input chopper for modulation, an AC coupling for offset rejection and a correlated double sampling structure for demodulation, avoiding ripple spurs.

Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

open access: yesJournal of Applied Polymer Science, EarlyView.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,

Chopper Capacitively Coupled Instrumentation Amplifier Capable of Handling Large Electrode Offset for Biopotential Recordings

open access: yes, 2017
This brief presents the design of a low-noise chopper capacitively coupled instrumentation amplifier (CCIA). To accommodate the input with large electrode offset (EOS), the amplifier includes a coarse digital dc-servo loop (DSL) in addition to a fine ...

Concurrent High Tibial Osteotomy, Anterior Cruciate Ligament Reconstruction, and Medial Meniscus Posterior Root Repair

open access: yesArthroscopy Techniques, EarlyView.
Abstract Medial meniscus posterior root tears and anterior cruciate ligament (ACL) injuries disrupt knee biomechanics and accelerate joint degeneration, particularly in the presence of varus malalignment. This technical note describes a combined surgical approach that integrates medial meniscus posterior root repair, ACL reconstruction, and high tibial

Real‐time biosensing of Parkinson's disease biomarkers via NIR‐activated upconversion nanoparticles

open access: yesBMEMat, EarlyView.
Schematic illustration of the luminescence resonance energy transfer‐driven core‐shell‐shell UCNPs (cssUCNPs@Fluo4) nanoprobe for simultaneous monitoring of Ca²⁺‐temperature dynamics in Parkinson's disease models. Abstract Parkinson's disease (PD) is a progressive neurodegenerative disorder with incompletely understood pathophysiology, necessitating ...

Land birds on atolls: diversity, origin, and function

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Dynamic‐FLPs Enabled by Orbital Hybridization Tuning: Boosting 100% CO Selectivity for Dilute CO2‐to‐CO Conversion

open access: yesCarbon Energy, EarlyView.
This study, for the first time, constructs photostructured dynamic frustrated Lewis pairs (DFLPs) via a p‐p orbital hybridization regulation strategy, achieving the 100% reduction of low‐concentration CO₂ to CO and breaking the stability‐activity trade‐off.
