Interfacial Diffusion-Reaction Coupling Strategy for CO Reduction on Copper Surface in Acidic Medium.

CO electroreduction reaction in acid medium to produce multicarbon (C) products has gained attention as an alternative to the traditional processes in neutral or alkaline solutions which often suffer from low single-pass conversion efficiency due to (bi)carbonate accumulation at the cathode. However, the CO conversion efficiency in acid remains unsatisfactory. Herein, a strong-polarized layer-covered Cu catalyst is developed as electrode for CO reduction reaction (CORR) in acid.

The effect of different exercise modalities on older adults' quality of life: an assessor-blinded randomized controlled trial.

This assessor-blinded randomized trial was designed to evaluate the effects of aerobic exercise, resistance training, and traditional Chinese gong methods on the quality of life (QoL) of older adults aged 66-96 years living in a nursing facility. Seventy - eight participants, who were over 65 years old, free from severe heart disease, asthma, and other conditions specified in the exclusion criteria, were randomly allocated into three groups to receive 12-24 weeks of different exercise interventions. The SF - 36 Health Survey Scale was employed to assess QoL before the intervention and 12 and 24 weeks after it.

Herb-Nanoparticle Hybrid System for Improved Oral Delivery Efficiency to Alleviate Breast Cancer Lung Metastasis.

Background: Metastasis is a complex process involving multiple factors and stages, in which tumor cells and the tumor microenvironment (TME) play significant roles. A combination of orally bioavailable therapeutic agents that target both tumor cells and TME is conducive to prevent or impede the progression of metastasis, especially when undetectable. However, sequentially overcoming intestinal barriers, ensuring biodistribution in tumors and metastatic tissues, and enhancing therapeutic effects required for efficient therapy remain challenging.

Photovoltaic-driven Ni(ii)/Ni(iii) redox mediator for the valorization of PET plastic waste with hydrogen production.

Electrocatalytic valorization of PET plastic waste provides an appealing route by converting intermittent renewable energy into valuable chemicals and high-energy fuels. Normally, anodic PET hydrolysate oxidation and cathodic water reduction reactions occur simultaneously in the same time and space, which increases the challenges for product separation and operational conditions. Although these problems can be addressed by utilizing membranes or diaphragms, the parasitic cell resistance and high overall cost severely restrict their future application.

An infrared image-enhancement algorithm in simulated prosthetic vision: Enlarging working environment of future retinal prostheses.

Background: Most existing retinal prostheses contain a built-in visible-light camera module that captures images of the surrounding environment. Thus, in case of insufficient or lack of visible light, the camera fails to work, and the retinal prostheses enter a dormant or "OFF" state. A simple and effective solution is replacing the visible-light camera with a dual-mode camera.
