Selective removal of cesium ions from aqueous solution by different metal (Zn/Ni) hexacyanocobaltate.

Radioactive Cs removal and treatment have attracted widespread attention since the Chernobyl disaster and the Fukushima Daiichi nuclear plant accident. So far, Prussian blue analogs (PBAs) are recognized as the most effective Cs adsorbents possessing excellent sorption ability and radiation resistance. Here, two types of PBA-based Cs adsorbents, potassium zinc hexacyanocobaltate (Zn-Co PBA) and potassium nickel hexacyanocobaltate (Ni-Co PBA), were prepared by chemical precipitation method.

BBOX1 restrains TBK1-mTORC1 oncogenic signaling in clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC), a metabolic disease originating from renal proximal convoluted tubule (PCT) epithelial cells, remains incompletely understood in terms of its initiating signaling events. Here, we identify γ-butyrobetaine hydroxylase 1 (BBOX1), a key enzyme in carnitine synthesis predominantly expressed in PCT cells, as a tumor suppressor in ccRCC. BBOX1 expression is lost during ccRCC malignant transformation, and its restoration reduces cell viability in physiological medium and inhibits xenograft tumor growth.

Pathogen Distribution and Antimicrobial Resistance of Early Onset Sepsis in Very Premature Infants: A Real-World Study.

Introduction: Early onset sepsis (EOS) remains a potentially fatal newborn condition, especially in very preterm infants. Data on the pathogen distribution and antibiotic susceptibility patterns of EOS among very preterm infants are scarce but essential for the choice of empirical antibiotic administration. We sought to assess the epidemiologic characteristics and antibiotic susceptibility patterns of pathogens causing EOS among a cohort of very preterm infants in China.

Social costs of tourism during the COVID-19 pandemic.

The severe acute respiratory syndrome coronavirus 2 is currently spreading across the world at an alarming rate, resulting in the coronavirus disease 2019 pandemic. Amidst this crisis, tourism scholars are directing their attention to communities at tourist destinations, looking at their safety and well-being and the costs that they will bear due to the cessation of tourism activity. This article describes residents' perceptions of the risks posed by tourism activity, and estimates their willingness to pay to reduce public health risks based on hypothetical scenarios, using the triple-bounded dichotomous choice contingent valuation method.

Interfacial modification by multifunctional octocrylene for high efficiency and stable planar perovskite solar cells.

Interfacial modification of the perovskite surface with octocrylene (2-ethylhexyl-2-cyano-3,3-diphenyl-2-propenoate, OCT) is capable of enhancing humidity stability and passivating the defects of perovskite films. In this study, octocrylene can be attached to the surface of the perovskite, and the carbonyl group (C[double bond, length as m-dash]O) in octocrylene achieved excellent passivation through the Lewis base electron passivation of Pb2+ ions. By increasing the concentration of the octocrylene/IPA solution, the modified device exhibited an optimal PCE of 20.

ECONOMIC IMPACTS OF VISA RESTRICTIONS ON TOURISM: A CASE OF TWO EVENTS IN CHINA.

Increasing attention has been paid to evaluate the impacts of large scale events on tourism demand. For providing policy suggestions, it should consider the economic impact of both events themselves and other factors. This paper evaluates the economic effects of visa restrictions on tourism as a result of the 1989 Tian'an Men Square Incident and the 2008 Beijing Olympic Games by using an innovative combination of econometric and computable general equilibrium (CGE) models.
