Correlated X‐Ray and Electron Microscopies of a Single Biphasic GaAs Nanowire

Small Methods, EarlyView.
Nano‐focused scanning X‐ray diffraction microscopy at a synchrotron light source, combined with transmission electron microscopy, reveals a clear correlation between the nanoscale distribution of cubic and hexagonal segments in a GaAs nanowire with subtle variations in inter‐reticular spacing, bending, and twisting.

Why Settle for the Status Quo? A Critical Assessment of Pension Liability Measurement Under IFRS and US GAAP

Abacus, EarlyView.
Relevance and faithful representation are identified by standard‐setters as fundamental qualitative characteristics for useful accounting information. We critically assess whether current pension measurement guidance under International Financial Reporting Standards (IFRS) and US generally accepted accounting principles (GAAP) results in pension ...

Amplification of GaSb-Based Diode Lasers in an Erbium-Doped Fluoride Fibre Amplifier

IEEE Photonics Journal, 2023
Building upon recent advances in GaSb-based diode lasers and Er-doped fluoride fibre technologies, this article demonstrates for the first time the fibre-based amplification of mid-infrared diode lasers in the wavelength range around 2.78 $\mu$m.

Human and Intellectual Capital Spending Efficiency and Efficacy: Evidence from U.S. Universities

Journal of Business Finance &Accounting, EarlyView.
ABSTRACT We analyze the efficiency and efficacy of human and intellectual capital investment to better understand the effects of social investment. Existing literature in the corporate setting lacks analysis on the impact of human and intellectual capital investment, likely due to data scarcity.

Ballistic electron emission microscopy spectroscopy study of AlSb and InAs/AlSb superlattice barriers [PDF]

, 1998
Due to its large band gap, AlSb is often used as a barrier in antimonide heterostructure devices. However, its transport characteristics are not totally clear. We have employed ballistic electron emission microscopy (BEEM) to directly probe AlSb barriers

When chemistry meets taxonomy: Studying glycolipidic chemomarkers in pelagic Sargassum spp. (Phaeophyceae) using molecular networking

Journal of Phycology, EarlyView.
Abstract To chemically differentiate the three pelagic Sargassum morphotypes co‐occurring in floating rafts and drifting across the Atlantic Ocean before stranding on West African, Caribbean, and Atlantic Mexican coastlines, we conducted an investigation of their metabolomic profiles.

Photoresponse investigation of polycrystalline gallium antimonide (GaSb) thin films

AIP Advances, 2020
Thin films of polycrystalline gallium antimonide (GaSb) were grown on widely available mica substrates using the physical vapor deposition method. The as-grown films contain grains of nano-scale with regular symmetries, as identified by x-ray diffraction
