Wetting Transparency of Single-Layer Graphene on Liquid Substrates.

Graphene's wetting transparency offers promising avenues for creating multifunctional devices by allowing real-time wettability control on liquid substrates via the flow of different liquids beneath graphene. Despite its potential, direct measurement of floating graphene's wettability remains a challenge, hindering the exploration of these applications. The current study develops an experimental methodology to assess the wetting transparency of single-layer graphene (SLG) on liquid substrates. By employing contact angle measurements and Neumann's Triangle model, the challenge of evaluating the wettability of floating free-suspended single-layer graphene is addressed. The research reveals that for successful contact angle measurements, the testing and substrate liquids must be immiscible. Using diiodomethane as the testing liquid and ammonium persulfate solution as liquid substrate, the study demonstrates the near-complete wetting transparency of graphene. Furthermore, it successfully showcases the feasibility of real-time wettability control using graphene on liquid substrates. This work not only advances the understanding of graphene's interaction with liquid interfaces but also suggests a new avenue for the development of multifunctional materials and devices by exploiting the unique wetting transparency of graphene.

Promoting resilience among older people in prisons: a systematic literature review.

The number of older people in UK prisons has increased significantly in recent years and most of them have at least one health condition. Research has shown that the physical and mental health of older people living in the community is positively correlated with resilience, but there is limited research on how to promote resilience in older prisoners. This systematic literature review offers a synthesis of interventions, practices and processes that may improve resilience in older prisoners. The review included eight peer-reviewed studies and identified three elements that support resilience in older prisoners: organised interventions; relational activities; and subjective processes. Healthcare professionals working in prisons can use the findings to identify how to support older prisoners' well-being and develop the conditions that may enable older prisoners to sustain and strengthen their resilience.

Functional improvements following the use of the NVT Vision Rehabilitation program for patients with hemianopia following stroke.

UNLABELLED: The incidence of visual deficits following stroke ranges from 20%-68% and has significant impact on activities of daily living. The NVT system is a compensatory visual scanning training program that consists of combined static and mobility training and transfer to activities of daily living. The study aims to evaluate functional changes following the NVT program for people who have homonymous hemianopia (HH) following stroke. METHOD: Interventional case series of 13 consecutive participants with HH undergoing NVT vision rehabilitation. The primary outcome measure was the number of targets missed on a standardized Mobility Assessment Course (MAC). Other outcome measures included assessment of visual scanning, vision specific Quality of Life questionnaires and reading performance. RESULTS: The average number of targets (sd) missed on the MAC course was 39.6 ± 20.9% before intervention, 27.5 ± 16.3% immediately post intervention and 20.8 ± 15.5% at 3 months post rehabilitation. The study showed a statistically significant trend in improvement in mobility related subscales of National Eye Institute Visual Function Questionnaire-NEI VFQ-25 (p=0.003) and the Veteran Affairs Low Vision Visual Function Questionnaire-VA LVFQ-48 (p=0.036) at 3 months post rehabilitation. DISCUSSION: The NVT intervention resulted in functional improvements in mobility post rehabilitation. The NVT training showed improvement in vision specific quality of life. There is a need for standardised vision therapy intervention, in conjunction with existing rehabilitation services, for patients with stroke and traumatic brain injury.

Vision-related quality of life in patients with complete homonymous hemianopia post stroke.

PURPOSE: The aim is to determine the characteristics of vision-specific quality of life restriction using the National Eye Institute Visual Function Questionnaire (NEI VFQ-25) and Veterans Affairs Low Vision Visual Function Questionnaire (VA LV VFQ-48) in patients with complete homonymous hemianopia (HH) post stroke. METHOD: Prospective cohort study of patients with complete HH compared to age- and gender-matched subjects with normal visual fields. RESULTS: In the NEI VFQ-25, scores on five subscales were significantly reduced after multiple logistic regression accounting for vision and comorbidities. The five subscales are vision-specific social functioning, vision-specific mental health, vision-specific dependency, driving, and peripheral vision. In the VA LV VFQ-48 postregression analysis, mobility is the only domain that is significantly affected in the people with HH. CONCLUSION: Identification of the significant areas of visual difficulties and their effects on quality of life is important as it can help better address the patients' rehabilitation needs. The current study identifies the need for orientation and mobility training as well as independent living rehabilitation in patients with HH to help address the difficulties in their vision-specific quality of life and maximize their residual vision.
