Ultralight (<10 milligrams per cubic centimeter) cellular materials are desirable for thermal insulation; battery electrodes; catalyst supports; and acoustic, vibration, or shock energy damping. We present ultralight based on periodic hollow-tube microlattices. These fabricated by starting with a template formed self-propagating photopolymer waveguide prototyping, coating the electroless nickel plating, subsequently etching away template. The resulting metallic microlattices exhibit...
The cold sintering process (CSP) is a low-temperature consolidation method used to fabricate materials and their composites by applying transient solvents external pressure. In this mechano-chemical process, the local dissolution, solvent evaporation, supersaturation of solute lead “solution-precipitation” for consolidating various nearly full densification, mimicking natural pressure solution creep. Because low processing temperature (&lt;300°C), it can bridge gap between ceramics,...
This work investigated the effect of sodium (Na) and potassium (K) ions permeation on optical properties vanadium dioxide (VO2) deposited three different glass substrates: silica-soda-lime (SL), silica-potash-soda (PS) fused quartz (FQ), respectively. The VO2 thin films were prepared by reactive magnetron sputtering. Microstructure compositions determined X-ray diffraction (XRD), energy dispersive spectroscopy (EDX) photoelectron (XPS). Morphology was characterized atomic force microscopy...
In this paper, mechanical performances of 480 specimens are tested and influences basalt fiber ratio, slenderness, soakage material studied. Results indicate that properties BFRC better than plain concrete. It can be found the best performance may get when soaked by water-solubility its ratio at 8.4 to 14 kg per square meter as well slenderness 600 800.
The spinel lithium titanates materials Li4Ti5O12 and LiTi2O4 were fabricated by pulsed laser deposition. High quality single phase thin films successfully grown, thus opening the door for a systematic investigation of optical properties system Li1+xTi2-xO4 (0≤ x ≤1/3). microstructure characterized X-ray diffraction atomic force microscope. studied spectroscopic ellipsometry at room temperature. refractive index, extinction coefficient, thickness obtained fitting experimental data over entire...
Size-dependent plastic flow behavior is manifested in nanoindentation, microbending, and pillar-compression experiments plays a key role the contact mechanics friction of rough surfaces. Recent using hard flat plate to compress single-crystal Au nano-pyramids others Berkovich indenter indent thin films show size scaling into 100-nm range where existing mechanistic models are not expected apply. To bridge gap between single-dislocation nucleation at 1-nm scale dislocation-ensemble plasticity...
Abstract The main cryogenic heat exchanger is a core piece of equipment in the liquefaction natural gas. printed circuit gradually becoming primary choice for exchanger, because it has good pressure resistance, high efficiency, and compactness. In this work, numerical simulation conducted to examine local flow transfer characteristics gas during trans-critical liquefaction. It found that flux density reaches minimum value worst when temperature difference between hot cold sides smallest....
