Performance of AAOmega: the AAT multi-purpose fibre-fed spectrograph

, 2006
AAOmega is the new spectrograph for the 2dF fibre-positioning system on the Anglo-Australian Telescope. It is a bench-mounted, double-beamed design, using volume phase holographic (VPH) gratings and articulating cameras.

Engineering Bilayer Tandem Catalysts on Si‐Based Photocathodes for High‐performance CO2 Reduction to Produce Methane

Advanced Materials, EarlyView.
A Cu/Ag‐Cu bilayer tandem catalyst is designed for a pyramid‐structured p‐Si photocathode, creating multiple and functionally distinct interfaces tailored to specific reaction steps and intermediate stabilization. This Cu/Ag‐Cu‐decorated p‐Si photocathode exhibits both high photocurrent and good selectivity for photoelectrochemical CO2 reduction to CH4.

Faster than Light Photons in Gravitational Fields II - Dispersion and Vacuum Polarisation

, 2002
Vacuum polarisation in QED in a background gravitational field induces interactions which effectively violate the strong equivalence principle and affect the propagation of light.

Virus del papiloma humano (VPH) y cáncer

Medicina y Laboratorio, 2021
Cada año, más de medio millón de mujeres en el mundo son diagnosticadas con cáncer cervical, usualmente asociado a la infección por virus del papiloma humano (VPH) de alto riesgo. Aunque la mayoría de las infecciones por VPH se resuelven dentro de un término menor de 2 años, algunos tipos virales, en particular el VPH16, pueden persistir por décadas y ...

From Design to Prototype: High‐Sensitivity Tri‐Mode Operation Photodetectors Based on 1T‐2H Hybrid MoS2

Advanced Science, EarlyView.
This work demonstrates a phase‐engineered MoS2 photodetector that dynamically switches among photocapacitive (PCC), photovoltaic (PV), and photoconductive (PC) modes. By transforming the traditionally parasitic capacitance into an active signal source, the device achieves self‐powered, high‐sensitivity detection with a fast response of 19.2 ms, and a ...

Carcinoma espinocelular cutáneo y papilomavirus (VPH)

Actas Dermo-Sifiliográficas, 2007
The relationship between mucosal human papillomavirus (HPV) and cervical carcinoma or anogenital squamous cell carcinoma (SCC) is becoming increasingly evident, whereas a link between HPV and other cutaneous SCCs is less clear. Recent studies have reported links between epidermodysplasia-verruciformis-associated HPV and extragenital cutaneous SCC ...

Modeling Acoustic Attenuation, Sound Velocity and Wave Propagation in Lithium‐Ion Batteries via a Transfer Matrix

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
“A simple 1D transfer matrix model of a battery is introduced and parametrized using harvested individual cell components at 0 % and 100 % SoC. This model allows for the calculation of group velocity and attenuation. The results of the model show good agreement with measured values, highlighting increased attenuation and group velocity at the ...

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...
