Zinc metal suffered from violent and long-lasting water-induced side reactions and uncontrollable dendritic Zn growth, which seriously reduced the coulombic efficiency (CE) and lifespan of aqueous zinc-metal batteries (AZMBs). To suppress the corresponding harmful effects of the highly active water, a stable zirconium-based metal-organic framework with water catchers decorated inside its sub-nano channels was used to protect Zn-metal. Water catchers within narrow channels can constantly trap water molecules from the solvated Zn-ions and facilitate step-by-step desolvation/dehydration, thereby promoting the formation of an aggregative electrolyte configuration, which consequently eliminate water-induced corrosion and side reactions...

Colour-tunable organic light-emitting diodes (CT-OLEDs) have a large colour-tuning range, high efficiency and operational stability at practical luminance, making them ideal for human-machine interactive terminals of wearable biomedical devices. However, the device operational lifetime of CT-OLEDs is currently far from reaching practical requirements. To address this problem, we designed a tetradentate Pt(II) complex named tetra-Pt-dbf, which can emit efficiently in both monomer and aggregation states. This emitter has a high Td of 508°C and a large intermolecular bonding energy of -52...

BACKGROUND: The available evidence regarding the predictive value of troponins and natriuretic peptides for early postoperative outcomes in pediatrics is limited, controversial, and based on small sample sizes. We aimed to investigate the association of N-terminal pro B-type natriuretic peptide (NT-proBNP) and high-sensitivity troponin T (hs-TnT) with the in-hospital adverse outcomes after congenital cardiac surgeries. METHODS: A secondary analysis based on a prospective study of pediatric congenital heart disease (CHD) patients was conducted to investigate the association of NT-proBNP and hs-TnT tested within 6 hours postoperatively with in-hospital adverse events...

The cotton mealybug, Phenacoccus solenopsis Tinsley and papaya mealybug, Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae) are becoming major threats to the production of Gymnema sylvestre R. Br. (Asclepiadaceae) in India. Management mainly depends on chemical insecticides which cause a serious problem of pesticide residue and insecticide resistance. The use of biorational insecticides such as biopesticides, botanicals, insect growth regulators, and microbial insecticides is important components of an Integrated Pest Management (IPM) program for successful management...

One-dimensional shaving-like BiVO4 nanobelts were successfully synthesized via the oxide hydrothermal method (OHS), using V2 O5 and Bi2 O3 as raw materials and PEG 10000 (polyethylene glycol 10000) as a template. Multiple techniques, including XRD, SEM, TEM, HRTEM, UV-Vis, XPS, and photoelectrochemical measurements, were applied to characterize the obtained materials. The thickness of the BiVO4 nanobelt was approximately 10 nm, while the width was approximately 500 nm. EIS results showed that visible-light illumination caused the photogenerated charge of the BiVO4 nanobelts to have a faster transfer and a higher separation efficiency...

In response to physical and psychological stressors, neurobiological processes are activated to maintain homeostasis. Stress alters the activity of the hypothalamic-pituitary-adrenal (HPA) axis. The mechanism for this effect is not yet clear. For the formation of moderate stress, the Chronic Immobilization Stress (CIS) model was chosen to perform the restriction of movement activity 2 hours every day for 20 days continuously. The impacts of CIS on cognitive function (elevated multi branch maze test) and Glucocorticoid receptor (GluR) levels in the hippocampus were studied in adult rats of both sexes...

The stability of organic solar cells is a key issue to promote practical applications. Herein, we demonstrate that the device performance of organic solar cells is enhanced by an Ir/IrOx electron-transporting layer, benefiting from its suitable work function and heterogeneous distribution of surface energy in nanoscale. Notably, the champion Ir/IrOx -based devices exhibit superior stabilities under shelf storing (T80  = 56696 h), thermal aging (T70  = 13920 h), and maximum power point tracking (T80  = 1058 h), compared to the ZnO-based devices...

STATEMENT OF THE PROBLEM: New calcium silicate base cements are introduced as root repair materials in order to defeat the problems of early root repair materials.

PURPOSE: This study was conducted to evaluate the solubility and porosity of the NanoFastCement (NFC) as a new calcium silicate base cement comparing to mineral trioxide aggregate (MTA). MATERIALS AND METHOD: In this in vitro study, scanning electron microscope (SEM) was used to evaluate the porosity at five different magnifications (200×, 1000×, 4000×, 6000× and 10000×) in secondary backscattered electron mode...

Rechargeable sodium metal batteries (RSMBs) with high energy density and low cost are attracting extensive attention as promising energy storage technologies. However, the poor cyclability and safety issues caused by unstable solid-electrolyte interphase (SEI) structure and dendrite issues limit their practical application. Herein, we theoretically predict that constructing the Ni3 S2 /Ni3 P heterostructure with high work function can lower the Fermi energy level, and therefore effectively suppressing continuous electrolyte decomposition derived from the electron tunneling effect after long-term sodiation process...

In recent years, the problem of diagnosing and treating neurotrophic keratopathy (NK) has become relevant in view of its prevalence reaching 1.6-11.0 per 10000 people. While previously it was associated only with neuroparalytic keratitis, at present the violation of sensitive and trophic innervation of the cornea with the development of characteristic keratopathy is observed in many diseases and injuries of the organ of vision. Diagnosis of NK is based on anamnestic information and assessment of clinical and functional parameters: determination of the stability of the tear film, tear production and assessment of staining of the ocular surface with vital dyes...

Herein, a novel conducting polymer complex PEDOT:CF3SO2(x)PSS(1-x) (denoted S-PEDOT:CF3SO2(x)PSS(1-x)) is fabricated assistant by Zinc di[bis(trifluoromenthylsulfonyl) imide](Zn(TFSI)2) (CFE). The introduction of CF3SO2- group is expected to bring better stability of PEDOT:CF3SO2 than PEDOT:PSS due to its strong Coulomb force. Electrochemical measurement shows that a high specific capacitance 194 F cm-3 was achieved from the novel complex S-PEDOT:CF3SO2(x)PSS(1-x), the highest value reported so far. All-solid-state supercapacitor with a structure of S-PEDOT:CF3SO2(x)PSS(1-x)/H2SO4:PVA/ S-PEDOT:CF3SO2(x)PSS(1-x) shows a record specific capacitance of 70...

Automated microscope slide stainers are usually very expensive and unless the laboratory performs heavy histological work it is difficult to justify buying a 2000-10000€ machine. As a result, histology and pathology labs around the world lose thousands of working hours for following procedures that could be easily automated. Herein, we propose a simple modification of an open-source 3D printer, the Creality Ender-3, into an automated microscope slide autostainer, the HistoEnder. The HistoEnder is cheap (less than 200€), modular, and easy to set up, with only two 3D-printed parts needed...

Dendrites growth, limited coulombic efficiency (CE) and the lack of high-voltage electrolytes restrict the commercialization of zinc batteries and capacitors. These issues are resolved by a new electrolyte, based on the zinc(II)-betaine complex [Zn(bet)2 ][NTf2 ]2 . Solutions in acetonitrile (AN) avoid dendrite formation. A Zn||Zn cell operates stably over 10110 hours (5055 cycles) at 0.2 mA·cm-2 or 110 hours at 50 mA·cm-2 , has an area capacity of 113 mAh·cm-2 at 80% depth of discharge. A zinc-graphite battery performs at 2...
