Crystal orientations in multiple orders correlate to the properties of polycrystalline materials, and it is critical manipulate these microstructural arrangements enhance device performance. Herein, we report a controllable approach facet orientation within ABX3 hybrid perovskites films by cation cascade doping at A-site. Two-dimensional synchrotron radiation grazing incidence wide-angle X-ray scattering employed probe crystal mixed thin films, revealing general pattern guide planes stacking...
The promising rubrene-based PSC device performance demonstrates the potential of rubrene as a suitable hole transport material in PSCs due to an optimal energy level alignment at rubrene/CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub> interface.
The quality of a perovskite film has great impact on its light absorption and carrier transport, which is vital to improve high-efficiency solar cells (PSCs). Herein, it demonstrated that graphene oxide (GO) can be used as an effective additive in the precursor solution for preparation high-quality solution-processed CH3NH3PbI3 (MAIPbI3) films. It evidenced by scanning electron microscopy size grains inside these films not only increases but also becomes more uniform after introduction...
Despite rapid successful developments toward promising perovskite solar cells (PSCs) efficiency, they often suffer significant hysteresis effects. Using synchrotron-based grazing incidence X-ray diffraction (GIXRD) with different probing depths by varying the incident angle, we found that films consist of dual phases a parent phase dominant in interior and child smaller (110) interplanar space (d(110)) after thermal annealing (RTA), which is widely used post treatment to improve...
A family of polyoxo(alkoxo)lanthanide cluster {Ln<sub>15</sub>} [Ln = Eu (<strong>1</strong>), Gd (<strong>2</strong>), Tb (<strong>3</strong>)] was successfully isolated via the simple hydrolysis reaction lanthanide metal ions in presence tricine ligand. X-ray diffraction analyses revealed display a wheel-like structure with <em>µ</em><sub>5</sub>-chloride anion as template. Interestingly, each analogue shows distinctive function based on different Ln(III) ions. The complexes...
This study aimed to assess the extractability of cadmium (Cd) and Cd uptake by rice after applying soil amendments lime (Ca(OH)2) sepiolite. A (Oryza sativa) cultivation experiment was conducted in a Cd-contaminated paddy field. After lime, sepiolite, mixture two as amendments, pH showed significant increase (p<0.05), extracted with NaNO3, CaCl2, DTPA, reduced 61–100%, 52–98%, 12–15%, respectively (p<0.05). The amount exchangeable decrease all treatments we found increases proportion forms...
GaN nano/microwires, due to their large surface-to-volume ratio and the reduced dimensionality, have been widely used in high-performance ultraviolet (UV) photodetectors (PDs). However, there has a fundamental trade-off between photocurrent gain speeds of PDs, which limited practical applications. In this work, highly ordered microwire array based Schottky UV PDs fabricated, optimizing Si doping concentrations can entirely improve performances devices. The results show that output increases...
Flow battery electrodes are vital for performing redox reactions, and an in-depth understanding of reaction kinetics spatial distribution differences in is very important improving the efficiency electrochemical reactions. In this study, a reflection-type phase-sensitive weak measurement imaging system was developed detection flow batteries. The phase difference between two polarization components total internal reflection caused by electrode processes measured value amplification. resulting...
Presently, porous materials have become essential to many technological applications. In this account, 3-dimensional skeleton composite consisting of a core–shell amorphous carbon/multilayer graphene are synthesized by chemical vapor deposition on Ni foam using facile one-step growth method. The data suggest that these composites not only outstanding electrical and mechanical properties the multilayer but also mesoporous characteristics carbon. Moreover, composited carbon perfectly inherit...
ABSTRACT Two novel polymeric acceptors based on naphthalene diimide (NDI) and 2.2′‐bithiophene, named as P(NDI2THD‐T2) P(NDI2TOD‐T2), were designed synthesized for all polymer solar cells application. The structural electronic properties of the two modulated through side‐chain engineering NDI units. optoelectronic polymers morphologies blend films composed a donor PTB7‐Th systemically investigated. With thiophene groups introduced into side chains units, both showed wider absorption from 350...

We show that through the wave energy conserved and reversible process of coherent interactions scalar waves in a multi-channel system joint by common junction, it is possible to generate outgoing only certain channels controlling incoming waves. refer such processes as perfect channeling (CPC). As two particular examples, we report experimental theoretical investigations CPC with three four-channel waveguides are completely channeled into one or other mediated deep subwavelength dimension...
