Visible-light-driven CO 2 reduction technology offers a promising solution for the worldwide challenges of climate crisis and energy shortage. A key issue in photocatalysis is to develop environmentally benign, low-cost materials ideally with earth-abundant elements with suitable oxidizing and reducing potentials. Her…
DNA-functionalized gold nanoparticles (AuNPs) often encounter various small molecules and ions such as backfilling agents, bifunctional cross-linkers, stabilizers, and molecules from biological fluids both during and after the DNA conjugation process. Small molecules and ions can influence the stability and property o…
Aluminum oxide nanoparticles were prepared and characterized with a wide variety of applications. This study aimed at the preparation of AlO2 nanoparticles by the liquid particles treated with laser (1064 nm), immersed in deionized water at varied laser energy (350 J/cm2) and diverse numbers of 300 pulse. For antimicr…
Cesium‐based inorganic perovskite solar cells (PSCs) have attracted great attention due to the superior thermal stability of the light absorbers. However, the reported devices normally contain organic charge‐transporting layers (CTLs), such as spiro‐OMeTAD, which is expensive and highly sensitive to ambient atmosphere…
The temperature-dependent microstructure evolution and corresponding mechanical stability of retained austenite in medium-Mn transformation induced plasticity (TRIP) 0.17C-3.1Mn-1.6Al type steel obtained by thermomechanical processing was investigated using scanning electron microscopy (SEM), electron backscatter diff…
The electride materials with free-electron gas have attracted intensive attention both experimentally and theoretically. Here, we demonstrate the effective modulation of the electronic and magnetic properties of monolayer electride Ca 2 N by hydrogenation based on first-principles calculations. The adsorption of hydro…
Porosity is one of the most important indicators for the characterization of the comprehensive performance of thermal barrier coatings (TBCs). Herein, we explored a fast, nondestructive porosity evaluation method based on the terahertz time-domain broadening effect. Different preparation process parameters were used t…
To reduce weight and improve overall performance of the industrial welding robot, light-weight design using the finite element method and structural topological optimization is presented in this paper. The work analyzed an upper arm of an industrial welding robot in the most unfavorable working condition, both under s…
Abstract Spin–orbit torques (SOTs) in ferromagnet (FM)/Ta/CoFeB trilayers are investigated as a function of Ta thickness. When the Ta is thinner than 1.5 nm, the sign of the SOT exerting on the top perpendicularly magnetized CoFeB depends on the bottom FM layer; it is positive for NiFe and negative for CoFeB. As the T…
Abstract The reduction of 2,4,6‐tri(4‐pyridyl)‐1,3,5‐triazine (TPT) with alkali metals resulted in four radical anion salts (1, 2, 4 and 5) and one diradical dianion salt (3). Single‐crystal X‐ray diffraction and electron paramagnetic resonance (EPR) spectroscopy reveal that 1 contains the monoradical anion TPT.− stac…
Driven by the exceptional success of 2,2′-bithiophene-3,3′-dicarboximide imide ( BTI ) for enabling high-performance polymer semiconductors, herein two BTI analogues 2,2′-bifuran-3,3′-dicarboximide ( BFI ) and 2,2′-biselenophene-3,3′-dicarboximide ( BSeI ) are designed and synthesized. The strong electron-withdrawing…
Na and cyano-group co-modified g-C3N4 was easily synthesized and its physicochemical property was completely analyzed. The results manifested that Na and cyano-group modification could heighten visible light absorbed ability and accelerate photoinduced charge separation. When resulted Na and cyano-group co-modified g-…
In this Letter, we report the broadband photoluminescence of lead-free double perovskite Cs2Na0.4Ag0.6In0.95Bi0.05Cl6:Mn2+. Under ultraviolet excitation, the white phosphor shows two emission peaks at 550 nm and 610 nm from self-trapped exciton and doped Mn2+ ions, respectively, leading to a broad emission spectrum ov…
Thin film lithium niobate has been of great interest recently, and an understanding of periodically poled thin films is crucial for both fundamental physics and device developments. Second-harmonic (SH) microscopy allows for the noninvasive visualization and analysis of ferroelectric domain structures and walls. While…

Therefore, the development of quantitative detection of methods for H 2 O 2 is necessary. Here, we constructed of a nove…
Abstract Sources of carrier compensation in n-type and p-type GaN layers grown by metalorganic vapor phase epitaxy were quantitatively identified by a combination of Hall-effect analysis and deep level transient spectroscopy. For n-type GaN, we identified three electron compensation sources: residual carbon atoms like…
A two-dimensional mathematical model has been developed for characterizing and predicting the dynamic performance of an air-cathode MFC with graphite fiber brush used as anode. The charge transfer kinetics are coupled to the mass balance at both electrodes considering the brush anode as a porous matrix. The model has…
Ordered mesoporous/microporous carbon was synthesized from sucrose. The carbon was oxidized and modified with urea at 600, 800, and 950 °C. The obtained carbons differed in the pore size distributions in the meso- and micropore ranges. The carbons, after an extensive surface characterization, were used as ORR catalyst…
