Abstract Frequency combs show various applications in molecular fingerprinting, imaging, communications, and so on. In the terahertz frequency range, semiconductor-based quantum cascade lasers (QCLs) are ideal platforms for realizing comb operation. Although self-started operation can be obtained free-running QCLs due to four-wave mixing locking effects, resonant/off-resonant microwave injection, phase locking, femtosecond laser based techniques have been widely used broaden stabilize QCL...
An initial improvement in performance of PbS quantum dot solar cells composed one thick layer dots (QDs) treated with tetrabutylammonium iodide (PbS-TBAI) and thin QDs capped 1,2-ethanedithiol (PbS-EDT) over short-term air exposure is widely observed. However, the underlying mechanisms still remain elusive. In work, we sought to understand as well their physicochemical origins using a combination X-ray photoelectron spectroscopy (XPS) various electronic measurements. It found that PbS-TBAI...
Neferine inhibits the angiotensin II (AngII)-induced proliferation of vascular smooth muscle cells (SMCs), but underlying mechanism is unclear. The aim this study was to explore effect neferine on SMCs. Rat aortic SMCs (RASMCs) were used and fractalkine (Fkn) gene expression measured by quantitative polymerase chain reaction western blot analysis. RASMCs analyzed MTT assay flow cytometry. It revealed that AngII induced Fkn in a dose- time-dependent manner. Fkn-knockdown with small...
Angiotensin II (Ang II) is a neuroendocrine factor that promotes hypertension and has been implicated in vascular inflammation through the induction of reactive oxygen species (ROS) proinflammatory genes endothelial cells. However, relatively little attention paid to effect Ang on fractalkine (FKN), an important chemokine involved dysfunction. In study, we aimed investigate protective role total flavonoids from Plumula Nelumbinis (TFPN), main component extracted Semen Nelumbinis, II-induced...
The instability of perovskite films is a major issue for solar cells based on ZnO electron transport layers (ETLs). Here, nanoparticle (NP)- and sol-gel capped with low-temperature processed TiO2, namely ZnO/TiO2 bilayered films, have been successfully employed as ETLs in highly efficient MAPbI3-based cells. It demonstrated that these are not only capable enhancing photovoltaic performance, but also improving device stability. best the ETL exhibits an efficiency ∼15% under standard test...

In a deep eutectic solvent (DES) that composed of choline chloride and ethylene glycol, 3,4-dihydropyrimidin-2(1H)-ones were synthesized via Biginelli reaction catalyzed by p-toluenesulfonic acid (p-TSA).3,4-Dihydropyrimidin-2(1H)ones under mild conditions with high yield.High purity products obtained direct filtration without further purification.This catalytic system can be recycled, the catalysts, solvents remaining reactants directly recycled separation.The results showed catalyst up to...
Abstract Frequency combs with equally spaced frequency lines show great potentials for applications in spectroscopy, imaging, communications, and so on. In the terahertz region, quantum cascade laser (QCL) is an ideal radiation source comb dual-comb operation. The systematic evaluation of phase noise characteristics QCL sources importance high precision measurements. this work, we present detailed measurements analysis emitting around 4.2 THz repetition frequencies ~6.2 GHz. measurement...
Primary hypertension is one of the most well-known risk factors for cardiovascular disease. Currently, there still no ideal indicator left ventricular end-diastolic pressure.73 patients and 37 healthy people were enrolled in this study. Each member was examined with conventional echocardiography including multiple indicators such as Peak mitral valve flow velocity (E, A), E/A, atrial volume index (LAVl), tissue Doppler (PW-TDI) peak velocities during early late diastolic (e '), E/e ', GLS....
In this paper, a kind of temperature sensor which can detect small-area heat source with high sensitivity is designed by using the property different thermal expansion coefficients materials. The sensitive element silicon nitride cantilever beam coated metal on its upper surface. Due to difference between and nitride, will bend in direction rapid change gradient, bending amount be positively correlated when ambient changes. experiment, measured optical lever, relationship output voltage...
