Influence of Top Electrode Metal on Resistive Switching in Multilayer MOCVD MoS2 Memristors

Advanced Electronic Materials, EarlyView.
MoS2 memristors typically use evaporated noble metal electrodes. This study compares Pd, Ni, and Al electrodes and sputtered versus evaporated deposition. Pd is passive, while Ni damages MoS2, yielding poor switching. Sputtered Al enables reproducible ECM‐type switching with 95% yield, whereas evaporated Al forms an interfacial oxide that suppresses ...

Drift Reduction in 2D PtSe2 Piezoresistive Pressure Sensors Through an On‐Chip Wheatstone Bridge

Advanced Electronic Materials, EarlyView.
Drift is a major source of error affecting the accuracy and repeatability of sensors. A Wheatstone bridge (WSB) enables high sensitivity, accuracy, and the elimination of common‐mode drift. We apply the WSB concept to highly sensitive piezoresistive pressure sensors made with two‐dimensional layered platinum diselenide transducers.

Negotiating contested spaces and places: Narratives of social suffering and resistance in racialized Cape Town communities

American Journal of Community Psychology, EarlyView.
Abstract This study employs a schizocartographic approach to explore community narratives of space, memory, and violence in Kraaifontein, Cape Town. Through participants' accounts, ordinary places—gardens, shops, blocks, sports grounds, and streets—emerge as ambivalent geographies where trauma, resilience, and belonging intersect.

Systemic Hormonal Contraceptive Use Is Associated With Greater Odds of Rotator Cuff Tears, Shoulder Instability, Dislocation, and Other Shoulder Pathologies: A Propensity Matched Epidemiological Study

Arthroscopy, EarlyView.
Purpose To evaluate whether systemic estrogen‐only, progestin‐only, or combined hormonal contraceptives (HCs) are associated with increased risk of shoulder pathologies in reproductive‐age females. Methods A retrospective cohort study of female patients presenting to clinic from 2013 to 2020 and aged 13‐50 with 5 years of follow‐up was conducted using ...

Glucagon‐Like Peptide‐1 Receptor Agonist Use in Obese Patients Is Associated With Decreased Risk of Revision and Retears After Arthroscopic Rotator Cuff Repair

Arthroscopy, EarlyView.
Purpose To evaluate the impact of preoperative glucagon‐like peptide‐1 receptor agonist (GLP‐1 RA) use on medical complications, emergency department use, and orthopaedic complications in obese patients undergoing arthroscopic rotator cuff repair. Methods Obese patients (defined by relevant ICD‐10 codes and confirmed by body mass index measurements ...
