Microorganisms are essential agents of Earth's soil weathering engine who help transform primary rock-forming minerals into soils. Mycorrhizal fungi, with their vast filamentous networks in symbiosis with the roots of most plants can alter a large number of minerals via local acidification, targeted excretion of ligan…
Scaling down the size of metal–organic framework (MOF) particles is a challenging but important task for extending the spectrum of potential MOF applications. Herein, we describe downsizing particles of MFU-4, a benzobistriazolate-based Zn(II)-MOF, which can be prepared by either solvothermal or microwave-assisted syn…
Heat recovery plays an important role in energy saving in the supply chain of steel products. Almost all high temperature outputs in the steel industry have their thermal energy exchanged to preheat inputs to the process. Despite the widespread development of heat recovery technologies within process stages (process h…
Green synthesis of iron oxide nanorods were achieved by utilizing rich polyphenols in Omani mango tree leaves as a reducing agent. The obtained Iron (III) oxide nanorods (IONRs) were (15 ± 2) nm in average length and (3.0 ± 0.2) nm in average diameter. These nanorods were polycrystalline in structure with different di…
In this study, films of gallium oxide (Ga2O3) were prepared through remote plasma atomic layer deposition (RP-ALD) using triethylgallium and oxygen plasma. The chemical composition and optical properties of the Ga2O3 thin films were investigated; the saturation growth displayed a linear dependence with respect to the…
Electrical charge flowing through organic semiconductors drives many of today's mobile phone displays and television screens, suggesting an internally consistent model of charge-carrier properties in these materials to have manifested. In conjugated polymers, charges give rise to additional absorption of light at wave…
Locating core-shell metal nanoparticles into a photoactive layer or at the interface of photoactive layer/hole extraction layer is beneficial for fully employing surface plasmon energy, thus enhancing power conversion efficiency (PCE) in plasmonic organic photovoltaic devices (OPVs). Herein, we first investigated the…
A new small molecule using 2D benzodithiophene with fluorinated thiophene side chains as a central unit, D3RTBDTTF, is synthesized for highly efficient small molecule solar cells (SM-OSCs). The pristine D3RTBDTTF device shows an efficiency of 9.24%. The efficiency is further increased to 9.80% after a solvent-vapor an…
PURPOSE: To evaluate renal allografts function early after transplantation using intravoxel incoherent motion (IVIM) and arterial spin labeling (ASL) MRI. METHODS: This prospective study was approved by the local ethics committee, and written informed consent was obtained from all participants. A total of 82 participa…
The authors systematically characterize the three-orbital Hubbard model using state-of-the-art determinant quantum Monte Carlo (DQMC) simulations with parameters relevant to the cuprate high-temperature superconductors. The DQMC results agree well with those from cuprate experiments, such as photoemission, and enable…
Recently it has been proposed the study of a new class of bidimensional metamaterials, 33, 34 which have been called extensible pantographic sheets. Such bidimensional continua are the generalization of the continua introduced in 68, 69, 80 as they take simultaneously into account the elastic energy in the extensional…
Linear mono- and polydisperse homopolymer melts have been investigated with Fourier transformation rheology (FT rheology) to quantify their nonlinear behavior under oscillatory shear via mechanical higher harmonics, i.e., I 3/1 (ω,γ 0 ). Master curves of the zero-strain nonlinearity, 3 Q 0 (ω) ≡ lim γ 0 →0 I 3/1 /γ 0…
Triboelectric nanogenerators (TENGs) have shown exciting applications in mechanical energy harvesting and self‐powered sensing. Aiming at commercial applications, cost reduction and simplification of TENG structures are of great interest. In this work, a lightweight TENG based on the integration of polymer nanowires a…
Precessional switching allows subnanosecond and deterministic reversal of magnetic data bits. It relies on triggering a large-angle, highly nonlinear precession of magnetic moments around a bias field. Here we demonstrate that a surface acoustic wave (SAW) propagating on a magnetostrictive semiconducting material prod…
Here we report a class of photocatalysts: mixed-valence vanadium oxide particles grafted onto a variety of oxide supports. In these catalysts V 6 O 13 species with mixed oxidation states (V 4+ or V 5+ ) are believed to be catalytically active sites. These catalysts successfully enable alcohol oxidation to selectively…
Low phase noise mode-locked fiber laser finds important applications in telecommunication, ultrafast sciences, material science, and biology, etc. In this paper, two types of carbon nano-materials, i.e. single-wall carbon nanotube (SWNT) and graphene oxide (GO), are investigated as efficient saturable absorbers (SAs)…
Metal-halide perovskites are novel optoelectronic materials that are considered good candidates for solar harvesting and light emitting applications. In this study, we develop a reproducible and low-cost approach for synthesizing highquality cesium lead halide perovskite (CsPbX 3 , X = Cl, Br, and I or Cl/Br and I/Br)…
Metal-free graphitic carbon nitride (g-C 3 N 4 ) shows benign photocatalytic abilities concerning contaminant decomposition and hydrogen evolution under visible light irradiation. Developing facile modification tactics for promoted activity of g-C 3 N 4 has always been desirable and worth pursuing. Herein, we report t…
The development of a facile and sustainable approach to produce magnesium oxide (MgO) activated carbons impregnated through a single-step activation of biochar is reported. In a single-step activation process, biochar is impregnated with 3 and 10 wt % of magnesium salt solutions followed by steam activation. In a two-…
The combination of stem cell therapy with a supportive scaffold is a promising approach to improving cardiac tissue engineering.
