The capability of controlling the phase of the nonlinear polarization of media is vital for nonlinear optical beam shaping. Achieving this control over nonlinear phase manipulation on the nanoscale facilitates modern on-chip photonic integration of nonlinear beam shaping. Plasmonic metasurfaces with thickness down to…
Curcumin is a natural compound extracted from turmeric (Curcuma longa), which has been reported to be a promising anti‑cancer drug in various human cancers. However, the effects of combination treatment of curcumin with gemcitabine or docetaxel on pancreatic cancer remains elusive. In the present study, the combinator…
High-purity silicon is a readily available material of utility in realizing a variety of long-wavelength optical and guided wave components. The transmittance of uncompensated for silicon is measured in the far- and mid-infrared regimes at room and cryogenic temperatures. The experimental and analysis techniques used…
Since obtaining a highly oriented structure based on a large-scale commercial ultra-high molecular weight polyethylene (UHMWPE) is considered very difficult due to its high molecular weight and melting index, modifying the structure of these cheap commercial UHMWPE brands into a supra-molecular structure with fiber-fo…
Recent experiments on twisted double bilayer graphene report evidence of uniform spin and valley orders as well as spin-triplet superconductivity. Here, the authors perform perturbative renormalization group analyses for electrons near Van Hove singularities to investigate competition among all possible instabilities.…
The construction of solar active photoelectrodes for photoelectrochemical purposes based on a heterojunction platform is one of the most promising strategies. Herein, a molybdenum disulfide–graphitic carbon nitride (MoS 2 –GCN) p–n heterojunction stabilized reduced graphene oxide/indium tin oxide (rGO/ITO) photoelectr…
Abstract Potassium-ion batteries or KIBs are prominent candidates among research involving post lithium-ion batteries due to abundant availability, low-cost, and low standard reduction potential of potassium metal. Although some chemistry correlation with other monovalent alkali metal-ion batteries may exist, research…
Pesticide spraying droplets are prone to break and splash when they reach the leaf surface, especially for hydrophobic leaves. The lost pesticide will not deposit on the leaf surface to exert its effect, which eventually enters the environment to cause pollution and even endanger human health. The need to increase spr…
Although hybrid halide perovskites $(\text{MAPb}{X}_{3},$ $\mathrm{MA}={\mathrm{CH}}_{3}{\mathrm{NH}}_{3} \mathrm{and} X=\mathrm{I}, \mathrm{Br}, \mathrm{Cl})$ have been ubiquitously explored from the photovoltaic perspective, there are still a few unanswered questions which require a more fundamental understanding. O…
The authors use thermoelectric power and Hall-effect measurements to give evidence of a magnetic field-induced Fermi surface reconstruction in the heavy fermion superconductor UTe${}_{2}$ at the metamagnetic transition, which coincides with the abrupt suppression of superconductivity at 35 T for magnetic field applied…
Detecting toxic gases is of great importance to protect our health and preserve the quality of life. In this work, graphene (G) and graphene oxide with three different modifications (G–O, G–OH, and G–O–OH) have been used to detect hydrogen selenide (H2Se), hydrogen telluride (H2Te), and phosphine (PH3) molecules based…
High Resolution Image Download MS PowerPoint Slide In this work, a porous hydrogel-based adsorbent for metal ions was prepared through the copolymerization of acrylic acid and 2-hydroxyethyl methacrylate using a high internal phase emulsion (HIPE) method. Stretched molecular chains in the hydrogel ensure the excellent…
The low electronic conductivity of spinel-structured Li 4 Ti 5 O 12 could be improved by introducing CuV 2 O 6 . Herein, several Li 4 Ti 5 O 12 /CuV 2 O 6 composites with different CuV 2 O 6 contents have been successfully prepared by a facile liquid-phase dispersion technique. The amount of CuV 2 O 6 in composites is…
Abstract Solid-state nanopore (SSNP) technology presents an emerging single-molecule based analytical tool for separation and analysis of biomolecules or nanoparticles. Different prominent approaches have been pursued to attain the anticipated detection performance: process innovation to achieve pore size matching the…
Through density functional theory calculations, we unravel a microscopic picture of the catalytic NO oxidation activity of the MIL-100 MOF platform. By systematically varying the nature of the coordinatively unsaturated metal sites (Al, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Ru), we demonstrate the relative energy of the…
CdSeTe alloying has significantly increased the efficiency of CdTe-based solar technology. Here, computational modeling compares how different CdSeTe bandgrading, carrier lifetimes, band alignment, and carrier concentrations contribute to transport, recombination, and performance. We find that the gain in photocurrent…
The microstructure, phase composition, and mechanical properties during heat treatment and rolling of the novel Al-5.0Cu-3.2Er-0.9Mn-0.3Zr alloy were evaluated. A new quaternary (Al,Cu,Mn,Er) phase with possible composition Al25Cu4Mn2Er was found in the as-cast alloy. Al20Cu2Mn3 and Al3(Zr,Er) phases were nucleated du…
Abstract The application of metal–organic frameworks (MOFs) as SERS‐active platforms in multiplex volatile organic compounds (VOCs) detection is still unexplored. Herein, we demonstrate that MIL‐100 (Fe) serves as an ideal SERS substrate for the detection of VOCs. The limit of detection (LOD) of MIL‐100(Fe) for toluen…
A novel three-dimensional sulfonated poly(ether sulfone) (SPES) nanofiber@ZIF-8 network (ZSNF) with an interlaced structure was designed and prepared by an in situ assembling zeolitic imidazolate framework-8 (ZIF-8) shell on electrospun SPES nanofiber surfaces. By incorporating ZSNFs into the Nafion matrix, highly com…
We report frozen patterns for the water droplets impacting on a cold substrate through fast-speed images. These patterns can be manipulated by several physical parameters (the droplet size, falling height, and substrate temperature), and the scaling analysis has a remarkable agreement with the phase diagram. The obser…
