We demonstrate an interesting phenomenon that graphene can emit sound. The application of be expanded in the acoustic field. Graphene-on-paper sound source devices are made by patterning on paper substrates. Three sheet samples with thickness 100, 60, and 20 nm were fabricated. Sound emission from is measured as a function power, distance, angle, frequency far-field. theoretical model air/graphene/paper/PCB board multilayer structure established to analyze directivity, response, efficiency....
Theoretical and experimental studies have been performed to simulate optimize graphene/semiconductor heterojunction solar cells. By controlling graphene layer number, tuning work function adding an antireflection film, a maximal theoretical conversion efficiency of ∼9.2% could be achieved. Following the optimization proposal, Schottky junction cells with modified films silicon pillar arrays were fabricated found give up 7.7%.

Aqueous zinc-ion batteries (AZIBs) have received widespread attention owing to the increasing demand for safety and inexpensive batteries. However, a zinc metal anode suffers from dendrite growth during continuous cycling, side reactions occurred on surface such as hydrogen evolution reaction (HER) passivation. Moreover, low utilization of Zn is also neglected issue leading energy density at cell-level. Herein, nondendrite with high was designed by spontaneous commercial powders graphene...
Graphene-on-silicon Schottky junction solar cells were prepared with pillar-array-patterned silicon substrate. Such patterned substrate showed an anti-reflective characteristic and led to absorption enhancement of the cell, which enhanced performance short-circuit current density, open-circuit voltage, fill factor, energy conversion efficiency 464.86 mV, 14.58 mA/cm2, 0.29, 1.96%, respectively. Nitric acid was used dope graphene film cell a great improvement increasing 3.55%. This is due...
A single-layer graphene film was grown on copper foil by chemical vapor deposition and transferred onto a silicon-pillar-array (SPA) substrate to make Schottky junction solar cell. The SPA specifically designed suppress reflectance enhance light absorption. energy conversion efficiency of the prepared graphene/SPA cells achieved maximum 2.90% with area 0.09 cm2. HNO3 employed dope in cells, time dependence treatment cell performance studied. Poly(3,4-ethylenedioxythiophene)...
ABSTRACT Separator is a very important set of lithium‐ion batteries. At present, low porosity and poor thermal stability are two major disadvantages separator. In this work, we first apply electrospinning method to prepare the Polytetrafluoroethylene (PTFE) nanofiber separator, which has advantages PTFE materials. The effect separator investigated by scanning electron microscope, Capillary Flow Porometer, thermogravimetric–differential calorimeter, linear sweep voltammeter, AC impedance,...
We report the structural, dielectric, and multiferroic properties of single-phase Y Zr co-doped BiFeO3 (BFO) ceramics. Enhancement in dielectric properties, frequency independence, ferroelectric are observed BFO due to reduction oxygen vacancies by co-doping. Co-doped samples exhibited double hysteresis loop-like magnetization-magnetic field curves with a significantly enhanced remnant magnetization (∼0.41496 emu/g when concentration is 0.15 0.05). The possible reasons may be co-doping...
Solid-state lithium metal batteries (LMBs) are considered as one of the promising contenders for next-generation energy storage systems because their high density and safety performance. Since all-solid-state electrolytes still hampered by low electrical conductivity interfacial incompatibility, gel polymer (GPEs) more preferable with ionic conductivities comparable to liquid at room temperature good contact electrodes. In this study, a high-performance composite GPE semi-interpenetrating...
Tertiary carbon radicals are usually more stable than secondary radicals, and the hydrogen atom transfer (HAT) from C(sp3)–H bonds to tertiary is normally considered be a thermodynamically disfavored pathway. Herein, we disclose an unusual protocol involving functionalization enabled by cyclopropyl radical proceeding through abstraction variety of aliphatic bonds. The reaction can furnish valuable, densely functionalized cyclopropane derivatives. Sufficient mechanistic experiments density...
Resistance random access memory devices based on nanoscale diamondlike carbon (DLC) films are demonstrated. The exhibit excellent performances such as high on/off-resistance ratio (>; 300), switching speed ( <; 50 ns), low operation voltage 1.2 V), power consumption 16 μW), nondestructive readout, and good reliability. Nanoscale graphitic filament formation rupture alternately through the field-induced dielectric breakdown thermal fuse effect, respectively, proposed to be responsible for...
Ferroelectric poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] (70/30) copolymer thin films were prepared by spin-coating method. The microstructure and morphology of P(VDF-TrFE) annealed at different temperatures (70°C-160°C) investigated atom force microscope X-ray diffraction techniques, which reveal the crystallization is greatly affected annealing temperature. With increase temperature, grains film change from small spheroids to long needle-like structures. most rapid occurs...
To exploit an efficient supercapacitor, improving the comprehensive properties of electrode materials has become important goal. In this work, NiCo2S4 nanosheets were successfully combined with highly conductive carboxylated carbon nanotubes (CNT-h-COOH) by electrochemical deposition, forming interconnected porous network nanosheets/CNT composite on nickel foam.

Gastric schwannoma is a relatively rare submucosal mesenchymal tumor with low probability of metastasis and arises from Schwann cells the gastrointestinal nervous plexus. Surgical therapy main treatment gastric symptoms or malignant tendency. Gastroparesis potential complication following surgery, which clinical syndrome caused by emptying disorder characterized nausea, vomiting, bloating, resulting in insufficient nutrient intake. Generally, post-surgical etiology gastroparesis, while most...
phage therapy is a promising approach for infections caused by drug-resistant bacteria; this study evaluated the impact of pre-exposure to particles on subsequent therapy. Mice were exposed intradermally (i.d.) Staphylococcus aureus wide-host-range JD007, member Myoviridae family. phage-specific antibodies detected using ELISA. infected with S. in same way establish dermal abscess model, and then efficacy mice pre-exposed JD007 was evaluated. could induce their specific IgM IgG. levels...
