We developed a novel melt-based embedded printing strategy to fabricate polycaprolactone (PCL) structures with complex overhanging geometries within thermally stable supporting matrix. By optimising the concentration of matrix, process parameters, and inter-filament thickness, continuous PCL filaments can be stably printed smallest width 50.6 ± 4.7 μm. The one-step in situ post-solidification provides unique approach regulate surface morphology filaments, reduce structural anisotropy....
In recent years, with the rapidly increasing demand for pure protein products in various fields (biomedicines, biochemical reagents, food industries, etc.), need low-cost, high-quality purification technology has become urgent. Under this background, traditional technology, crystallization, comes back to people's attention. Protein crystallization ability obtain at a low cost. Nevertheless, itself is challenging; long time, industrial of proteins often used chromatography-based approaches....
The contact angle, as a vital measured parameter of wettability material surface, has long been in dispute whether it is affected by gravity. Herein, we the advancing and receding angles on extremely low angle hysteresis surfaces under different gravities (1-8G) found that both them decrease with increase underlying mechanism revealed to be deformation liquid-vapor interface away from solid surface caused gradient distribution hydrostatic pressure. real not gravity cannot an optical method....
Bulk metallic glasses (BMGs), like other glasses, soften in the super-cooled liquid region (SCLR). Here this work, surprisingly, a large expansion is reported occurring deep SCLR of Zr47Cu37Al8Ag8 BMG. Nano-crystals (NCs) are found precipitated during anomalous Zr47Cu37Al8Ag8, but also Zr43Cu41Al8Ag8 that exhibits conventional softening. It there steep composition and density change at NCs/amorphous matrix transition former alloy, exerts thermal stress about 0.15 MPa to surrounding (SCL)...
An adherent hydroxyapatite (HA) coating was deposited on sodium silicate treated carbon/carbon composites (ST-C/C) through the induction heating deposition technique and hydrothermal process. The modified C/C surfaces have been characterised by X-ray photoelectron spectroscopy. It demonstrates that can be bonded to silicate. Besides, phase compositions morphology of coatings ST-C/C were identified diffraction, scanning electron microscopy (SEM) energy dispersive final consists dense...
Microwave pyrolysis chemical vapour infiltration was used for the rapid fabrication of carbon/carbon composites. The carbon fibre felts (the bulk density≈0·2 g cm−3) were densified with total pressures 50 kPa and CH4/N2 = 1 : 4 at 1100 1150°C respectively. results show that composites density 1·70 cm−3 can be fabricated 1100°C 90 h, are from inside out. stereomicroscope images reveal surfaces not sealed 1100°C, pyrolytic carbons deposited uniformly on fibres. polarised light pyrocarbon...
The commenters point out that when two fundamental locking mode injection-locked oscillators are cascaded together, they can easily provide 280 degrees plus phase shift. total shift of the cascade is related to overlapping region and due accumulation in each suboscillator. A simple theory explain effect cascading suboscillators together proposed, a graphical model suggested frequency-detuning-induced X. Zhang A. S.
