Graphite like C3N4 (g-C3N4) was synthesized facilely via the low temperature thermal condensation of melamine between 300-650°C. The results showed that products maintained as when is below 300°C. With increase temperature, were transformed into carbon nitride and amorphous g-C3N4 successively. morphology changed from spherical nanoparticles layer with temperature. photoluminescence spectra have continuous tunable properties in visible region increasing help steady state, transient state...
The normalized PL emission spectra of graphite-like carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) modified with different non-metal ions (boron and sulfur) exhibit interesting scientific variation.
The biodegradable hybrid double-network hydrogel for stem cell-enhanced bone regeneration.
Many approaches have been made toward the development of scaffolds with good biocompatibility and appreciable physicochemical properties to facilitate stem cell adhesion, osteogenic differentiation, vascularization in tissue engineering. Nowadays, is a main bottleneck engineering strategies that needed be overcome developed. Herein, we construct series polyhedral oligomeric silsesquioxane (POSS)-modified porous gelatin hydrogels different POSS concentrations from 0 5 wt %, defined as X% (X =...
In nature, many plants have evolved various wettability surfaces to survive and thrive in diverse environments. For example, the superhydrophobic surface of lotus can keep itself clean, while rose petals retain droplets for a long time. The former is referred "lotus effect," latter known as "rose petal effect." This research proposes method fabricate magnetic-responsive magnetorheological elastomers (MREs) which could reversibly instantly transition their wetting state between effect" These...
We present the results of a search in LIGO O2 public data for continuous gravitational waves from neutron star low-mass X-ray binary Scorpius X-1. signals with $\approx$ constant frequency range 40-180 Hz. Thanks to efficiency our pipeline we can use long coherence time and achieve unprecedented sensitivity, significantly improving on existing results. This is first that has been able probe wave amplitudes could balance accretion torque at radius. Our excludes emission this level between...
Insufficient oxygen availability in tissue engineering is one of the major factors for failure clinical transplantation. One potential strategy to conquer this limitation fabrication spontaneous and continuous supplying scaffolds situ regeneration. In work, a versatile fluorine-incorporating hydrogel designed which can not only timely continuously supply mesenchymal stem cells (MSCs) overcome deficient before vascularization scaffolds, but present higher antibacterial capability avoid...
An abundance of refractory cellulose is the key limiting factor restricting resource utilization efficiency silkworm (Bombyx mori) excrement via composting. Screening for cellulose-degrading bacteria likely to provide high-quality strains safe and rapid decomposition excrement.
