With the continuous development of the social economy and the deepening of urbanization, large buildings are increasing, and disaster risks associated with large buildings, such as fire risks, are also increasing. Because of large buildings, such as shopping malls, business offices, transportation hubs...

Polymer composites reinforced with natural and synthetic fibres have emerged as promising materials owing to their tailored structural, mechanical and functional properties. Natural fibres such as jute, flax, and sisal are biodegradable, renewable, lightweight in nature, and cost-effective, making them...

The construction of heterojunctions is widely regarded as one of the most effective strategies for suppressing charge recombination, extending the light absorption range of a single photocatalyst, and significantly enhancing hydrogen production through photocatalytic water splitting. Herein, we explore...

To improve the corrosion resistance of N80steel, Ni-W-P coating was prepared by electroless deposition. The corrosion properties for Ni-W-P coating were investigated in hypersaline ground brine. Results of weight loss tests show that the corrosion resistance of the Ni-W-P coating is 10 times of N80steel...

GaN nanostructured films have been successfully grown through radio frequency magnetron sputtering system via annealing GaN/ZnO films in ammonia ambient at 950 . The volatilization of ZnO buffer layer plays an important role in the formation process of GaN nanostructures. X-ray diffraction (XRD), transmission...

In recent years, metal surface analysis is becoming a hot topic, especially for the new composite materials used in high speed trains and aircraft. Metal surface analysis techniques are used to reveal the material surface morphology, structure, composition or state. This paper presents typical instruments...

The improved Hummers method was used to prepare the graphene oxide. Then, using the precursor as the carrier and the triblock copolymer P123 as the reductant, the protective agent and the morphology control agent, the liquid phase co-reduction method and the continuous reduction method were respectively...

Pt/TiO2-xNy film has been synthesized successfully through the sol-gel method and spin coating method. The roughness and absorption wavelength were analyzed by atomic force microscopy (AFM) and ultraviolet and visible spectrophotometer(UV-vis). X-ray photoelectron spectroscopy(XPS) showed that the elements...

Alloy nanoparticles (NPs) of gold and palladium were found to be more active in oxidation of benzyl alcohols than supported gold or supported palladium NPs. The enhanced activity of benzyl alcohol oxidation at the surface of the alloy NPs can be explained by the charge heterogeneity. To confirm the charge...

A facile hydrothermal method was successful to synthesize the TiO2 by using unique bacterial cellulose (BC) membranes as natural biotemplates. The three-dimensional networks of BC fibers coated with TiO2 nanoparticles can be clearly observed, resulting in the formation of uniform and well-defined hybrid...

The Chinese civilization has been bursting with vitality and vigor in the process of dialogue with other cultures, especially with the Western classic Bible. The “best” translation of the supreme master of Christianity is one of the core issues in the process of translating the Bible into Chinese. In...

Palladium nanoparticles (Pd NPs) supported on active carbon was prepared via ultrasonically treating Pd precursors in ethylene glycol without any protective agents. The Pd/C nanocatalysts were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy...

From XPS and EPS of building external thermal insulation system on the advantages and disadvantages of using, EPS more in line with market demand, EPS has good weather resistance and temperature change of dimensional stability, is the most extensive domestic and international building exterior wall thermal...

Humans experience three phases in life, namely birth, marriage, and death. Nativity symbolizes the beginning of life, the moment when a new human being begins to breathe the air of the world. It is an event that brings great joy to the family and community, a symbol of hope and the future. Marriage as...

The black swan event has the characteristics of rarity and serious consequences. At present, the analysis of black swan events is generally preconceived (that is, the event is assumed to be a black swan event, and then the influence of the event is discussed), or whether it is a black swan event is directly...

In this work, the surface of Q235 steels was treated by air plasma to improve the adhesion between epoxy coatings and Q235 steels. The epoxy coatings were prepared through the electrostatic spraying. The disbonding test was used to characterized the adhesion strength of epoxy coatings. Meanwhile, the...

We have been synthesized MoO3 nanobelts by thermal chemical vapor deposition. The growth products will be studied by field emission scanning electron microscope (FESEM), X-ray photoemission (XPS), Raman Spectroscopy, X-rays diffraction (XRD). SEM images showed the belts-like nanostructures. XPS and Raman...

The optimal management of hemodynamic disorders among critically ill patients requires an accurate assessment of hemodynamic status. Global End Diastolic Index (GEDI) is taken for a more reliable indicator of preload in critically ill patients than central venous pressure and doctors tend to arrange...

Background: Interleukin-6 (IL-6) was considered to be with the severity and mortality in COVID-19 patients, which implies a potential therapeutic target for treatment. We aimed to evaluate the safety and initial efficacy of Tocilizumab treatment for COVID-19 patients. Methods: In the retrospective study,...

Purpose: Delirium is a frequent occurrence amongst Intensive Care Unit (ICU) patients, but studies on its causes are sparse and its risk factors vary from disease to disease. Here, in this study, an attempt was made to investigate the factors associated with the prognosis of delirium in the ICU. Methods:...
