A Well‐Advanced High‐Throughput Test System for Electrocatalytic Screening Applications Under Industrial Relevant Conditions – A Perspective to Accelerate Electrolysis Research and Development

open access: yesElectrochemical Science Advances, EarlyView.
ABSTRACT Electrolysis is a dynamic research area in which both mature and new promising processes, such as alkaline water electrolysis and electrochemical CO2 reduction, are under enormous development pressure due to their high relevance for the energy sector.

Spectroscopy of Blue Stragglers and Turnoff Stars in M67 (NGC 2682)

open access: yes, 2000
We have analyzed high-resolution spectra of relatively cool blue stragglers and main sequence turnoff stars in the old open cluster M67 (NGC 2682).

GelCam: Visualizing sinking particle flux via a polyacrylamide gel‐based sediment trap

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Sinking particles play a key role in the biological carbon pump. While previous studies have analyzed particulate carbon flux over timescales of days to years, few have been able to resolve flux variability on shorter, hourly scales at multiple depths simultaneously.

UBVI CCD Photometry of the Old Open Cluster NGC 1193

open access: yes, 2008
We present UBVI photometry of the old open cluster NGC 1193. Color-magnitude diagrams (CMDs) of this cluster show a well defined main sequence and a sparse red giant branch.

A Dual‐Programmable Metasurface with Duplex Beam Steering for Full‐Space Terahertz Communications

open access: yesLaser &Photonics Reviews, EarlyView.
A dual‐programmable terahertz metasurface enables independent control of transmission and reflection beam steering. It breaks through the limitations in resonant tunability by polarization allocation with 2D‐electron‐gas tuning, enabling a single resonator to incorporate bidirectional operating modes.

A Galactic Center Origin for HE 0437-5439, the Hypervelocity Star near the Large Magellanic Cloud

open access: yes, 2010
We use Hubble Space Telescope imaging to measure the absolute proper motion of the hypervelocity star (HVS) HE 0437-5439, a short-lived B star located in the direction of the Large Magellanic Cloud (LMC).

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

open access: yesLaser &Photonics Reviews, EarlyView.
This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...
