Evaluating the Local Bandgap Across inxGa1‐xas Multiple Quantum Wells in a Metamorphic Laser via Low‐Loss EELS

open access: yesAdvanced Materials Interfaces, EarlyView.
This research explores local bandgap, composition, and strain variations across InxGa₁−xAs quantum wells within a metamorphic laser structure using high‐resolution scanning transmission electron microscopy (STEM) and low‐loss electron energy loss spectroscopy (EELS). Results reveal significant inhomogeneities, particularly near interfaces, with bandgap

Ultrathin Gold for Robust Multi‐Element Surface Plasmon Resonance Biosensing

open access: yesAdvanced Materials Interfaces, EarlyView.
This is a pioneering work where for the first time we applied recently synthesised ultrathin layer of gold for plasmonic biosensing that makes use of multi‐element architectures. This study solves the problem of stability of the multi‐element biosensors as well as demonstrates increased sensitivity achieved by utilising new additions to low‐dimension ...

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

open access: yesAdvanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.

Contactless Tracking of Decomposition in Self‐Reporting Ceramic Cr‐Al‐B Coatings

open access: yesAdvanced Materials Interfaces, EarlyView.
Proof of concept for contactless tracking of decomposition in self‐reporting ceramic Cr‐Al‐B coatings in extreme environments by contactless resistivity measurements is demonstrated. To verify the results, high resolution in situ and ex situ methods are employed.

Relativistic Binaries in Globular Clusters

open access: yesLiving Reviews in Relativity, 2006
The galactic population of globular clusters are old, dense star systems, with a typical cluster containing 10^4 - 10^7 stars. As an old population of stars, globular clusters contain many collapsed and degenerate objects. As a dense population of stars,

Novel Use of Laser Zone‐Drawing on Nanofibers Enables Ultra‐Fast Thermal Kinetics and Precise Diameter Control

open access: yesAdvanced Materials Technologies, EarlyView.
This work explores the thermal kinetics of laser‐zone‐drawn electrospun nanofibers. Laser‐zone drawing is a technique that allows for localized heating of nanofiber segments, which results in better mechanical drawing. The high surface‐to‐volume ratio of nanofibers allows for ultrafast thermal kinetics at small diameters.
