As the gap between lithium supply and demand continues to widen, the need to develop ion-selective technologies, which can efficiently extract lithium from unconventional water sources, grows increasingly crucial. In this study, we investigated the fundamentals of applying a solid-state electrolyte (SSE), typically used in battery technologies, as a membrane material for aqueous lithium extraction. We find that the anhydrous hopping of lithium ions through the ordered and confined SSE lattice is highly distinct from ion migration through the hydrated free volumes of conventional nanoporous membranes, thus culminating in unique membrane transport properties.

Gypsum (CaSO·2HO) plays a critical role in numerous natural and industrial processes. Nevertheless, the underlying mechanisms governing the formation of gypsum crystals on surfaces with diverse chemical properties remain poorly understood due to a lack of sufficient temporal-spatial resolution. Herein, we use in situ microscopy to investigate the real-time gypsum nucleation on self-assembled monolayers (SAMs) terminated with -CH, -hybrid (a combination of NH and COOH), -COOH, -SO, -NH, and -OH functional groups.

Article Synopsis
  • Periodontitis is influenced by various environmental and genetic factors, with microbial infections like the Epstein-Barr virus (EBV) playing a crucial role, but the direct causal relationship between EBV and periodontitis remains unclear.
  • The study used advanced methods like Mendelian randomization and genetic analysis to explore the connection between EBV exposure and periodontitis, finding that higher EBV antibody levels are linked to an increased risk of developing the disease.
  • The research suggests that early-life exposure to EBV may have protective effects against periodontitis and highlights the potential for developing antiviral treatments and vaccination strategies to manage EBV-related periodontal issues.

Objectives: Identifying the specifics and potential causes of mumps outbreaks in the Fujian Province during the period of 2017 to 2022.

Methods: Mumps cases reported by the National Notifiable Communicable Disease Report System (NNCDRS) in China during the observation period of the 5 years were investigated annually and by age to detect homogeneity of the spread of the disease over time. If specific age-peaks may appear, we investigated those figures by analysing group characteristics in mumps cases presented as outbreaks.

Organic solvent nanofiltration (OSN) is an emerging membrane technology that could revolutionize chemical separations in numerous vital industries. Despite its significance, there remains a lack of fundamental understanding of solvent transport mechanisms in OSN membranes. Here, we use an extended Flory-Rehner theory, nonequilibrium molecular dynamic simulations, and organic solvent transport experiments to demonstrate that solvent flow in OSN membranes is driven by a pressure gradient.

Periodontitis drives irreversible destruction of periodontal tissue and is prone to exacerbating inflammatory disorders. Systemic immunomodulatory management continues to be an attractive approach in periodontal care, particularly within the context of 'predictive, preventive, and personalized' periodontics. The present study incorporated genetic proxies identified through genome-wide association studies for circulating immune cells and periodontitis into a comprehensive Mendelian randomization (MR) framework.

Artificial photocatalytic CO reduction (COR) holds great promise to directly store solar energy into chemical bonds. The slow charge and mass transfer kinetics at the triphasic solid-liquid-gas interface calls for the rational design of heterogeneous photocatalysts concertedly boosting interfacial charge transfer, local CO concentration, and exposure of active sites. To meet these requirements, in this study heterostructures of CdS/MOL (MOL = metal-organic layer) furnishing different redox Co sites are fabricated for COR photocatalysts.

The unavoidable and detrimental formation of silica scale in engineered processes necessitates the urgent development of effective, economic, and sustainable strategies for dissolved silica removal from water. Herein, we demonstrate a rapid, chemical-free, and selective silica removal method using electrosorption. Specifically, we confirm the feasibility of exploiting local pH dynamics at the electrodes in flow-through electrosorption, achieved through a counterintuitive cell configuration design, to induce ionization and concomitant electrosorption of dissolved silica.

  • COVID-19 disrupted regular dental care in China from 2020 to 2022, prompting a study to assess its impact on patient follow-up at Zhejiang University Stomatology Hospital.
  • The study included 1062 periodontitis patients, with data collected through a telephone questionnaire covering demographics, clinical data, and reasons for follow-up loss.
  • Results revealed that personal factors (42.5%) were the primary reason for loss to follow-up, followed by work (19.8%) and hospital-related issues (16.4%), while the COVID-19 epidemic itself accounted for only 20%.

Nonaqueous Li-O battery (LOB) represents one of the promising next-gen energy storage solutions owing to its ultrahigh energy density but suffers from problems such as high charging overpotential, slow redox kinetics, Li anode corrosion, etc., calling for a systemic optimization of the battery configuration and structural components. Herein, an ingenious "trinity" design of LOB is initiated by implementing a hollowed cobalt metal organic framework (MOF) impregnating iodized polypyrrole simultaneously as the cathode catalyst, anode protection layer, and slow-release capsule of redox mediators, so as to systemically address issues of impeded mass transport and redox kinetics on the cathode, dendrite growth, and surface corrosion on the anode, as well as limited intermediate solubility in the low donor-number (DN) solvent.

Background: Recent research has established the correlation between gut microbiota and periodontitis via oral-gut axis. Intestinal dysbiosis may play a pivotal bridging role in extra-oral inflammatory comorbidities caused by periodontitis. However, it is unclear whether the link is merely correlative or orchestrated by causative mechanistic interactions.

Hybrid organic/inorganic composites with the organic phase tailored to modulate local chemical environment at the Cu surface arise as an enchanting category of catalysts for electrocatalytic CO reduction reaction (CO RR). A fundamental understanding on how the organics of different functionality, polarity, and hydrophobicity affect the reaction path is, however, still lacking to guide rational catalyst design. Herein, polypyrrole (PPy) and polyaniline (PANI) manifesting different Brønsted basicity are compared for their regulatory roles on the CO RR pathways regarding *CO coverage, proton source and interfacial polarity.

Chromatin regulators drive cancer epigenetic changes, and lncRNA can play an important role in epigenetic changes as chromatin regulators. We used univariate Cox, LASSO, and multivariate Cox regression analysis to select epigenetic-associated lncRNA signatures. Twenty-five epigenetic-associated lncRNA signatures (CELncSig) were identified to establish the immune prognostic model.
