A simple one-step solvent-bathing process based on solvent–solvent extraction, is demonstrated for the controlled room-temperature crystallization of uniform, ultra-smooth hybrid-perovskite thin films high-efficiency solar cells.
Among the most fundamental observables of nucleon structure, electromagnetic form factors are a crucial benchmark for modern calculations describing strong interaction dynamics nucleon's quark constituents; indeed, recent proton data have attracted intense theoretical interest. In this Letter, we report new measurements factor ratio using recoil polarization method, at momentum transfers Q2=5.2, 6.7, and 8.5 GeV2. By extending range Q2 which G(E)(p) is accurately determined by more than 50%,...
Industrial application of metallic materials is hindered by several shortcomings, such as proneness to corrosion, erosion under abrasive loads, damage due poor cold resistance, or weak resistance thermal shock stresses, etc. In this study, using the aluminum-magnesium alloy an example widely spread materials, we show that a combination functional nanoengineering and nanosecond laser texturing with appropriate treatment regimes can be successfully used transform metal into superhydrophobic...
Volcanic ash ingested by jet engines can damage conventional Y2O3-stablized ZrO2 thermal barrier coatings (TBCs) used to protect engine parts in the hot section. Newer TBCs, one based on Gd2Zr2O7 and another composed of solid solution containing Y2O3, Al2O3, TiO2, are found be highly resistant such from Eyjafjallajökull volcano ash.

Abstract The fusion power density produced in a tokamak is proportional to its magnetic field strength the fourth power. Second-generation high temperature superconductor (2G HTS) wires demonstrate remarkable engineering current (averaged over full wire), J E , at very fields, driving progress and other applications. key challenge for HTS has been offer an acceptable combination of consistent superconducting performance volume supply, low price. Here we report reproducible practical based on...

The crystal morphology of organolead trihalide perovskite (OTP) light absorbers can have profound influence on the solar cells (PSCs) performance. Here we used a combination conventional transmission electron microscopy (TEM) and high-resolution TEM (HRTEM), in cross-section plan-view, to characterize morphologies solution-processed OTP (CH3NH3PbI3 or MAPbI3) within mesoporous TiO2 scaffolds capping planar layers. Studies specimens prepared with without use focused ion beam (FIB) show that...
Resistive and capacitive switching in capacitor metal/nanocomposite/metal (M/NC/M) structures based on (CoFeB)x(LiNbO3)100-x NC fabricated by ion-beam sputtering with metal content x $\approx$ 8-20 at. % is studied. The peculiarity of the structure synthesis was use increased oxygen ($\approx$ 2*10^-5 Torr) at initial stage growth. films, along nanogranules 3-6 nm size, contained a large number dispersed Co (Fe) atoms (up to ~10^22 cm^-3). Measurements were performed both DC AC (frequency...
Manganese oxide octahedral molecular sieves with increasing nanoscale tunnel sizes are systematically synthesized using hydrothermal treatment of Na-birnessite under pH conditions. OMS-5 (2×4), OMS-6 (2×3), and OMS-7 (1×1; see Figure) structures have been at values 13, 7.0, 1.0, respectively.

We have designed multifunctional silver alginate hydrogel microcontainers referred to as loaded microcapsules with different sizes by assembling them via a template assisted approach using natural, highly porous calcium carbonate cores. Sodium was immobilized into the pores of particles followed cross-linking addition ions, which had dual purpose: on one hand, were used agent, albeit in monovalent form, while other hand they led formation nanoparticles. Monovalent an unusual improve...

Abstract Effective production of oil from carbonate reservoirs often requires the application improved recovery technologies such as waterflooding. However, conventional waterflooding in carbonates usually results low hydrocarbon most these formations exhibit a complex pore throats structure and are mostly oil-wet. Therefore, insight into causes hydrophobic wetting behavior is important for understanding fluid distribution, displacement enhancing processes. The characterization fluid-rock...

A unique combination of acid treatment, aqueous colloidal processing, and spark-plasma sintering (SPS) has been used to fabricate high-density Al2O3 /single-wall carbon nanotube (SWNT) composites with well-distributed SWNTs other nanostructures ('nano-onions', diamond) at grain boundaries. This approach could be obtain well-controlled microstructures ceramic/SWNT for tailored mechanical, electrical, thermal properties. In addition, the dispersing presented here controlled manipulation SWNTs.
