Memristors with Monolayer Graphene Electrodes Grown Directly on Sapphire Wafers.

The development of the memristor has generated significant interest due to its non-volatility, simple structure, and low power consumption. Memristors based on graphene offer atomic monolayer thickness, flexibility, and uniformity and have attracted attention as a promising alternative to contemporary field-effect transistor (FET) technology in applications such as logic and memory devices, achieving higher integration density and lower power consumption. The use of graphene as electrodes in memristors could also increase robustness against degradation mechanisms, including oxygen vacancy diffusion to the electrode and unwanted metal ion diffusion.

Precarious employment and associations with socio-demographic characteristics and self-reported health in Wales, UK.

Objectives: The study's aim was to explore the prevalence of precarious employment (PE) in Wales prior to the COVID-19 pandemic and examine associations with PE domains across socio-demographics and self-reported health.

Study Design: A cross-sectional design was used to explore the prevalence of PE in Wales prior to the COVID-19 pandemic, in February 2020.

Methods: Data were collected from a national household survey carried out in May/June 2020, with a sample of 1032 residents in Wales.

Five Forms of Coerced "Self-Produced" Child Sexual Exploitation Material: A Critical Interpretive Synthesis.

This review explored how the phenomenon of coerced "self-produced" child sexual exploitation material (CSEM) has been constructed in the literature using Critical Interpretative Synthesis. Selected keywords were systematically searched on relevant databases. Types of papers included were: peer-reviewed research articles; conceptual papers; commentary papers; theses; book chapters; systematic reviews; and government reports.

Factors associated with cognitive impairment before intracerebral haemorrhage: community-based neuropathological study.

Little is known about whether clinical, radiological or neuropathological features are associated with cognitive impairment before intracerebral haemorrhage. We conducted a community-based cohort study of 125 adults with intracerebral haemorrhage (lobar = 71, non-lobar = 54) with consent to brain autopsy. We compared small vessel disease biomarkers on diagnostic CT head and neuropathological findings including neurofibrillary tangles and amyloid plaques in adults without cognitive impairment versus cognitive impairment without dementia versus dementia before intracerebral haemorrhage, stratified by lobar and non-lobar intracerebral haemorrhage.
