Characterisation of spectroscopic properties of DOAS instruments using high-resolution solar spectra [PDF]

Atmospheric Measurement Techniques
The characterisation of spectroscopic properties of DOAS instruments is important for accurate trace gas retrievals. In this study, we investigate and extend existing methods for the determination of spectroscopic properties using high-resolution solar ...

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Portable Molecularly Imprinted Polymer Sensor for Rapid Swab‐Based Detection of Norovirus

Advanced Healthcare Materials, EarlyView.
This work reports a rapid, portable smartphone‐based sensor capable of detecting four norovirus genotypes from swab samples within 15 min. Sensor selectivity was validated through evaluation against four common live viruses. The swab‐based sampling process enabled simple sample preparation combined with the compact detection system, supporting use of ...

Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

Advanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Organic–Inorganic Hybrid Hole‐Selective Layer Interface Engineering for Enhanced Photoelectrochemical Water Oxidation on Bismuth Vanadate Photoanodes

Advanced Materials, EarlyView.
In this research the [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl] phosphonic acid (Me‐4PACz) self‐assembled monolayers (SAMs) to bond with NiOx is first designed to be the organic‐inorganic hybrid hole‐selective layers, which promotes the BiVO4 photoanodes photoelectrochemical water splitting performance with 6.9 mA cm−2 photocurrent at 1.23 VRHE and at ...

Retrieval of Aerosol Fine-Mode Fraction from Intensity and Polarization Measurements by PARASOL over East Asia

Remote Sensing, 2016
The fine-mode fraction (FMF) of aerosol optical depth (AOD) is a key optical parameter that represents the proportion of fine particles relative to total aerosols in the atmosphere.

Electrically Coded Retinomorphic Spectrophotodetector

Advanced Materials, EarlyView.
Self‐powered retinomorphic pyro‐photodetector is demonstrated that avoids machine‐learning post‐processing and covers 365–940 nm. Electrostatic balancing of built‐in potential produces an electrical wavelength code, delivering <3 nm wavelength decoding accuracy with ∼46 µs response.
