Reversible photochromism and reversible UCL modulation of TiO 2 :Yb 3+ ,Er ceramics were reported when alternating 405 nm LED 808 laser irradiation. The photochromic are promising materials in the field anti-counterfeiting.
Abstract Double perovskite (DP) phosphors attract extensive attention due to their potential applications in the field of optoelectronics. Photochromism‐induced luminescence modulation can extend application fields. However, designing and preparing DP with expected photochromic luminescent properties is still challenging. Herein, Ba 2 YTaO 6 : Yb 3+ , Er Co 2+ upconversion developed. The color sample turns from white pink upon 254 nm UV light irradiation, which fast fading 473 laser...
Abstract The reversible luminescence modification of inorganic phosphors has emerged as a promising field, enabling innovative applications such optical memory, multiple anti‐counterfeiting, and photoswitches. Traditional modulation techniques, core–shell structure design energy transfer‐related luminescent ions regulation, face challenges in achieving modification. Chromism induces color changes materials when stimulated by external fields electricity, heat, light. Combining chromism with...
Negative lattice expansion-induced upconversion luminescence (UCL) thermal enhancement can efficiently solve quenching of lanthanide ions, and the temperature sensing characteristics be obtained by combining with fluorescence intensity ratio technology.
Copper molybdenum-based selenides (CuMoSe) as promising hydrogen evolution catalysts have been widely applied in the electrocatalytic splitting of water, while their limited active sites and relatively poor oxygen activity restrict further application effective bifunctional electrocatalysts. Here, we report a simple hydrothermal method to fabricate rodlike NiCuMoSe arrays on nickel foam (Nix–CuMoSe/NF), morphology which is determined by Ni2+ ions because can promote growth structure....

Ribonuclease L (RNase L) cleaves RNA predominantly at single-stranded UA and UU dinucleotides. Intriguingly, hepatitis C virus (HCV) RNAs have a paucity of dinucleotides, relatively interferon (IFN)-resistant strains fewer dinucleotides than do more IFN-sensitive strains. In this study, we found that contextual features dramatically affected the efficiency RNase cleavage in HCV RNA. genotype 1a was cleaved by into fragments 200–1000 bases length, consistent with 10–50 sites within 9650-base...
The current popular pedestrian detection methods are mainly based on deep learning algorithms, including Faster R-CNN, YOLO, SSD and other algorithms. In this paper, the INRIA data set is used to improve accuracy of model recognition without increasing speed recognition.
Background: Studies have shown that pressure-controlled ventilation improves alveolar gas distribution. And inverse ratio has advantages of improving oxygenation in acute respiratory distress syndrome (ARDS) patients. However, the effects ration patients undergoes endotracheal intubation general anesthesia not been assessed. Objective: To investigate whether (PIV) would improve ventilatory and parameters as well lung function compared to conventional undergoing open abdominal surgery....
The cognitive behavioral model is considered the most comprehensive for explaining pathogenesis of health anxiety (HA). proposes 4 dysfunctional beliefs that play a vital role in developing and sustaining HA: a) likelihood contracting or having an illness, b) awfulness c) difficulty coping with d) inadequacy medical services. Health Cognitions Questionnaire (HCQ), widely used English populations, was developed assessing these core cognitions. As HA growing problem China, we translated HCQ...
The use of symmetry in electromagnetic structures provides a degree freedom that is increasingly exploited to manipulate wave propagation. recently discovered line waves occur at the one-dimensional interface between complementary metallic screens. A band gap can also be introduced by pairing structure with its inverse. These materials provide unidirectional propagation simple printed patterns. Other patterns take advantage valley produce similar effects. At optical frequencies, non-metallic...
Background: Excessive alcohol consumption produces adverse physical and mental health consequences generally, including college university students. A variety of risk factors the have been addressed for students however only a few studies focused specifically on Chinese This article reports study which investigated influencing current situation student consumption.Methods: stratified, random-cluster sampling approach was used 907 from Changsha, Hunan university. All participants completed...
