Stabilizing High-Valence Copper(I) Sites with Cu-Ni Interfaces Enhances Electroreduction of CO to C Products.

In this study, the copper-nickel (Cu-Ni) bimetallic electrocatalysts for electrochemical CO reduction reaction(CORR) are fabricated by taking the finely designed poly(ionic liquids) (PIL) containing abundant Salen and imidazolium chelating sites as the surficial layer, wherein Cu-Ni, PIL-Cu and PIL-Ni interaction can be readily regulated by different synthetic scheme. As a proof of concept, Cu@Salen-PIL@Ni(NO) and Cu@Salen-PIL(Ni) hybrids differ significantly in the types and distribution of Ni species and Cu species at the surface, thereby delivering distinct Cu-Ni cooperation fashion for the CORR. Remarkably, Cu@Salen-PIL@Ni(NO) provides a C2+ faradaic efficiency (FE) of 80.

Psychometric properties of stigma and discrimination measurement tools for persons living with HIV: a systematic review using the COSMIN methodology.

Background: The development of antiretroviral therapy broadly extends the life expectancy of persons living with HIV (PLHIV). However, stigma and discrimination are still great threat to these individuals and the world's public health care system. Accurate and reproducible measures are prerequisites for robust results.

Psychometric and Circumplex Properties Evaluation of the International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC) in Chinese People Living with HIV (PLWH).

Background And Purpose: With the improved life expectancy of people living with HIV (PLWH) due to widespread use of antiretroviral therapy (ART), there is a greater emphasis on enhancing long-term well-being and overall quality of life for PLWH. Understanding interpersonal personalities of PLWH can gain further insight into how to improve the overall quality of life in this population. The International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC) scale has been developed to assess interpersonal personalities of individuals, and this scale has been translated into Chinese.

Identifying care problem clusters and core care problems of older adults with dementia for caregivers: a network analysis.

Background: A shift in research interest from separate care problem to care problem clusters among caregivers of people living with dementia may contribute to a better understanding of dementia care. However, the care problems network among caregivers of people living with dementia are still unknown. This study aimed to identify care problem clusters and core care problems, and explore demographic variables associated with these care problem clusters among caregivers of people living with dementia.

Covalent Organic Frameworks Boost the Silver-Electrocatalyzed Reduction of CO: The Electronic and Confinement Effect.

The electrocatalytic reduction of CO to CO with high efficiency is one of the most promising approaches for CO conversion due to its considerable economic feasibility and broad application prospects. In this study, three Ag@COF-R (R = -H, -OCH, -OH) hybrids were facilely fabricated by impregnating silver acetate (AgOAc) into respective covalent organic frameworks (COFs) prepared in advance. They differ significantly in the crystallinity, porosity, distribution, size, and electronic configuration of AgOAc species, which thereby influences both the activity and the selectivity of electrolytic CO-to-CO transformation.

Patient-reported outcome measures of stigma and discrimination for people living with HIV: a systematic review protocol.

Objective: The objective of this systematic review is to apply COnsensus-based standards for the selection of health Measurement INstruments (COSMIN) methodology to review psychometric properties of patient-reported outcome measures (PROMs) of HIV-related stigma and/or discrimination.

Introduction: Due to the development of antiretroviral therapy, the life expectancy of people living with HIV is similar to the life expectancy of the rest of the population. However, HIV-related stigma and discrimination are still major barriers to improving the quality of life of persons living with HIV.

The effectiveness and sustainability of peer support interventions for persons living with HIV: a realist synthesis.

Background: Peer support is an important supplement to medical resources for persons living with HIV (PLHIV). However, previous studies have shown mixed results about intervention effects. It is necessary to explain the mechanism of peer support interventions' effectiveness and sustainability to help design more valid peer support interventions.

Exploring core mental health symptoms among persons living with HIV: A network analysis.

Context: Persons living with HIV (PLWH) commonly experience mental health symptoms. However, little is known about the core mental health symptoms and their relationships.

Objective: This study aimed to evaluate the prevalence of various mental health symptoms and to explore their relationships in symptom networks among PLWH.

Research misconduct knowledge and associated factors among nurses in China: A national cross-sectional survey.

Aim: To measure the knowledge level of research misconduct and explore its associated factors among nurses.

Background: Engagement in research misconduct by nurses may transfer to professional misconduct in the clinical setting, thereby jeopardizing the quality of patient care. We still know little about the research misconduct situation among nurses.

Electroreduction of carbon dioxide to multi-electron reduction products using poly(ionic liquid)-based Cu-Pd catalyst.

Electrocatalytic reduction of CO (CORR) to multi-electron (> 2e) products provides a green and sustainable route for producing fuels and chemicals. Introducing the second metal element is a feasible strategy for "managing" the key intermediate on Cu-based materials to further improve the CORR catalytic performance. In this work, palladium, which promises the generation of CO, was introduced into the poly(ionic liquid)-based copper hybrid (Cu@PIL) to construct a novel Cu-Pd bimetallic electrocatalyst (Cu@PIL@Pd).

Traffic congestion and the lifetime of networks with moving nodes.

For many power-limited networks, such as wireless sensor networks and mobile ad hoc networks, maximizing the network lifetime is the first concern in the related designing and maintaining activities. We study the network lifetime from the perspective of network science. In our model, nodes are initially assigned a fixed amount of energy moving in a square area and consume the energy when delivering packets.
