The electrocatalytic carbon dioxide (CO) reduction is challenged by the parasitic hydrogen evolution reaction (HER) especially in acidic media. Here, we elaborate that redox-active isoindigo, acting as a multifunctional co-catalyst, can pre-activate CO-bound intermediates and suppress HER upon the synergistic effects of Lewis acid-base adduct formation, intramolecular hydrogen-bond interaction, and interfacial water structure modulation. Modifying a silver catalyst with isoindigo substantially decreases the energy barrier for CO-to-*COOH conversion, which is regarded as the potential-limiting step of carbon monoxide production.

Obstructive Sleep Apnea (OSA) is a common respiratory disease characterized by recurrent airway block during sleep, which does great harm to the human body. Utilizing the electroencephalogram (EEG) has been proven instrumental in OSA detection, as sleep apnea occurrences induce discernible alterations in EEG patterns. In this study, we propose a Limited Penetrable Difference Visibility Graph (LPDVG) method to screen severe OSA.

Current catalysts face challenges with low formate selectivity at high current densities during the CO electroreduction. Here, we showcase a versatile strategy to enhance the formate production on p-block metal-based catalysts by incorporating noble metal atoms on their surface, refining oxygen affinity, and tuning adsorption of the critical oxygen-bound *OCHO intermediate. The formate yield is observed to afford a volcano-like dependence on the *OCHO binding strength across a series of modified catalysts.

Mesenchymal Stem Cells (MSC) have the potential for pluripotent differentiation, transformation into stromal cells, and release of various cytokines to accelerate tissue healing as well as fight against inflammatory response. However, the differentiation and maturation of MSC require considerable time, which limits their clinical application. To tackle this difficulty, we herein propose a strategy of "selective accelerated activation of MSC by photothermal effect (PTE)" based on our previous work of "laser-controlled platelet activation".

Chondrocyte senescence is a critical pathological hallmark of osteoarthritis (OA). Aberrant mechanical stress is considered a pivotal determinant in chondrocyte aging; however, the precise underlying mechanism remains elusive. Our findings demonstrate that SPI1 plays a significant role in counteracting chondrocyte senescence and inhibiting OA progression.

The electrochemical reduction of carbon dioxide (CO) to carbon monoxide (CO) is challenged by a selectivity decline at high current densities. Here we report a class of indigo-based molecular promoters with redox-active CO binding sites to enhance the high-rate conversion of CO to CO on silver (Ag) catalysts. Theoretical calculations and in situ spectroscopy analyses demonstrate that the synergistic effect at the interface of indigo-derived compounds and Ag nanoparticles could activate CO molecules and accelerate the formation of key intermediates (*CO and *COOH) in the CO pathway.

Article Synopsis
  • - Subchondral bone sclerosis is a major feature of osteoarthritis (OA), and while Forkhead box C1 (FoxC1) is known to influence inflammation in OA, its specific role in subchondral bone has not been previously studied.
  • - Research found higher levels of FoxC1 and Piezo1 in OA subchondral bone, and overexpression of these proteins in osteoblasts led to increased cell growth, YAP expression, osteogenic markers, and pro-inflammatory factor secretion.
  • - The study indicates that FoxC1's role in OA subchondral bone involves activation of Piezo1 and YAP signaling, suggesting that these pathways might offer new therapeutic targets for treating OA-related damage.*

Article Synopsis
  • The study aimed to explore how the condition of the anterior cruciate ligament (ACL) affects the results of mobile-bearing medial unicompartmental knee arthroplasty (UKA) in patients with anteromedial osteoarthritis.
  • Researchers analyzed data from 128 patients who underwent the surgery, categorizing them based on their ACL condition as normal, synovial defect, or longitudinal split, and found no significant differences in key baseline demographics across these groups.
  • At follow-up (around 40 months), all groups showed no significant cartilage wear or complications, and there were improvements in knee range of motion and pain scores, indicating that ACL integrity did not negatively impact short- and mid-term outcomes of the surgery.

Denitrification, anammox, and DNRA are three important nitrogen (N) reduction pathways in estuarine sediments. Although salinity is an important variables controlling microbial growth and activities, knowledge about the effects of changing salinity on those three processes in estuarine and coastal wetland sediments are not well understood. Herein, we performed a 60-d microcosms experiment with different salinities (0, 5, 15, 25 and 35 ‰) to explore the vital role of salinity in controlling N-loss and N retention in estuarine wetland sediments.

Icing and fogging on optical material surfaces bring various problems in daily life. Recently, some photothermal coatings have been reported to prevent the condensation or freeze of water droplets by increasing the surface temperature. However, it is a great challenge to apply them in practical conditions due to their opaqueness and poor mechanical wear-resistant property.

Renewable-electricity-powered carbon dioxide (CO) reduction (eCOR) to high-value fuels like methane (CH) holds the potential to close the carbon cycle at meaningful scales. However, this kinetically staggered 8-electron multistep reduction suffers from inadequate catalytic efficiency and current density. Atomic Cu-structures can boost eCOR-to-CH selectivity due to enhanced intermediate binding energies (BEs) resulting from favorably shifted d-band centers.

The extraction of sugarcane juice is the first step of sugar production. The optimal values of process indicators and the set values of operating parameters in this process are still determined by workers' experience, preventing adaptive adjustment of the production process. To address this issue, a multi-objective optimization framework based on a deep data-driven model is proposed to optimize the operation of sugarcane milling systems.

This paper presents a local micro-structured long period fiber grating (LMS-LPFG) ultra-broadband optical filter based on the wide bandwidth near the phase-matching turning point (PMTP). The structure of LMS-LPFG is obtained by dividing a LPFG into two parts of equal length and reducing the cladding radius of the second LPFG. At this time, the LMS-LPFG can be regarded as a cascade of two equal-length LPFGs with different resonance wavelengths.
