Cu(In,Ga)Se 2 (CIGS) solar cells without buffer layers, namely, buffer-free solar cells, and those with conventional CdS buffer layers were fabricated. Zn(O,S):Al (AZOS) was used as a transparent conductive oxide layer. The AZOS/CIGS interface in the buffer-free solar cells and the AZOS/CdS/CIGS interface in the CdS-b…
Abstract A series of spiro-1,3-dioxolanofullerenes with 6-, 7-, 8-, and 12-membered ring were synthesized by the acid-catalyzed reaction of fullerene epoxide with cycloalkanones. The LUMO levels of these fullerenes are 0.07–0.08 eV lower than that of PCBM, due to the electron-withdrawing ester directly bonded to the C…
An octahedron to hexahedron transformation has been observed in the phase transition in TcO 2 .
This article presented the energy absorption behaviors and damage mechanisms of 3D braided composites under transverse impact and low‐velocity impact with frequency domain analysis method. The transverse impact tests were contracted by modified split Hopkinson pressure bar with the impact velocities of 13.6, 17.8, and…
Zinc nanoparticles (NPs) of ∼10 nm in diameter were irradiated with 200 MeV Xe14+ ions with various fluences ranging from 2 × 1011 to 4 × 1014 ions/cm2. The shape elongation of the NPs and the mean inter-particle (IP) distance were evaluated by small angle X-ray scattering (SAXS) in the transmission configuration usin…
We investigated the stress effects on nP yellow excitons in Cu2O thin films recrystallized epitaxially in a sample gap between paired MgO substrates. In such samples, it is expected that a two-dimensional compressive stress acts on Cu2O because of the slightly larger lattice constant of Cu2O than of MgO. To clarify su…
Ce-doped CuInTe 2 (CICT) semiconducting compounds are successfully synthesized. The phase structures, optical, and electric properties are investigated using powder X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), X-ray photoelectron spectrometer (XPS), Raman spectrometer, ultraviolet and…
Amines were prepared by a reductive amination reaction in the presence of calcium hydride and Pt/C.
The present report introduces a novel module of the QuBiLS-MIDAS software for the distributed computation of the 3D Multi-Linear algebraic molecular indices. The main motivation for developing this module is to deal with the computational complexity experienced during the calculation of the descriptors over large data…
From flask to plaque characterisation in less than 4 hours. Extremely fast detection of atherosclerosis plaque by nanoparticle-based MRI.
Uniaxial tensile and compressive deformation behaviors of Fe-18Cr-18Mn-0.63N high-nitrogen austenitic stainless steel were investigated at different strain rates. It is found that, with increasing strain rate, the yield strength of the steel increases either under tension or compression, while the ultimate tensile str…
High performance polybenzoxazine resin can be obtained by introducing partially reduced graphene oxide (PRGO) into bis‐benzoxazine (B‐BOZ) resin to overcome the defects such as low char yield, weak mechanical properties, and poor toughness of B‐BOZ resin. By virtue of the good thermal resistance and graphitization acc…
Sonoporation mediated by microbubbles is being extensively studied as a promising technology to facilitate gene/drug delivery to cells. However, the theoretical study regarding the mechanisms involved in sonoporation is still in its infancy. Microstreaming generated by pulsating microbubble near the cell membrane is r…
A simple procedure has been developed for the processing of silicon wafers in order to facilitate the spatially resolved growth of thin solid films on their surfaces. Specifically, a combination of silylation and UV/ozonolysis was tested as a way to control the concentration of the surface hydroxo groups required for…

In this study, inclusion complexes (ICs) between host hydroxypropyl‐β‐cyclodextrin (HP‐β‐CD) and guest poly(vinyl alcohol) (PVA) were prepared through polymer processing with water as plasticizer and solvent. The structure of PVA/HP‐β‐CD ICs was confirmed by FTIR, 1H‐NMR and 2D‐NOESY NMR. The yields of PVA/HP‐β‐CD ICs…
Objects of research are coatings and technology of their applying to the piezoelectric elements for ultrasound. Results of studies the distribution coating thickness according to different modes of coating process are presented. Experimentally confirmed the simulation results of the movement gas suspension on the elec…
Abstract For sputtering targets, through‐thickness texture is critical for assuring reliable sputtering performance. In this paper, through‐thickness texture gradient of a rolled and subsequently annealed tantalum sputtering target was investigated. The results show that by carefully controlling the rolling process, s…
Plasmonic crystals provide many passive and active optical functionalities, including enhanced sensing, optical nonlinearities, light extraction from LEDs and coupling to and from subwavelength waveguides. Here we study, both experimentally and numerically, the coherent control of SPP beam excitation in finite size pl…
