Abstract Memristors have recently become powerful competitors toward artificial synapses and neuromorphic computation, arising from their structural electrical similarity to biological neurons. From the diversity of materials, numerous organic inorganic materials proven exhibit great potential in application memristors. Herein, this work focuses on a class memristors based frameworks (OFs) pay attention most advanced experimental demonstrations. First, typical device structures memristive...
Compounds with strong thermodynamic affinity for carbon dioxide (CO(2)) have been designed and synthesized that dissolve in CO(2), then associate to form gels. Upon removal of the these gels produced free-standing foams cells an average diameter smaller than 1 micrometer a bulk density reduction 97 percent relative parent material.
<italic>O</italic>-Acylated chitin was obtained directly from shrimp shells using ChCl/RCOOH (NADESs), which exhibited good antibacterial and anti-tumor effects.
We investigated the dependence of cations and anions ionic liquids (ILs) on catalytic activity for synthesis dimethyl carbonate (DMC) via transesterification ethylene (EC) with methanol (CH3OH), demonstrated that an easily prepared carboxylic functionalized imidazolium salt exhibited higher activity, 82% yield DMC together 99% selectivity was obtained under metal-free halogen-free conditions. The reaction mechanism also proposed according to experimental DFT studies. In addition, in order...
Ionic liquids (ILs) with different cations and anions were used to study the effects on 5-hydroxymethylfurfural (HMF) preparation. It was found that both aggregations of hydrogen bonds fructose played important roles. Molecular dynamics simulations also performed explain experimental results.
Abstract The knowledge tracing (KT) model is an effective means to realize the personalization of online education using artificial intelligence methods. It can accurately evaluate learning state students and conduct personalized instruction according characteristics different students. However, current models still have problems inaccurate prediction results poor features utilization. study applies XGBoost algorithm improve performance. In addition, also effectively handles multi-skill...
The recycling of poly(ethylene terephthalate) (PET) is an important issue for environmental protection and resource conservation. Methanol alcoholysis the main chemical method commonly used today to degrade PET into high-value monomers. However, conventional methanolysis has problems such as high temperature pressure. To further reduce methanolysis, in this work, cosolvent-enhanced methanol polyesters was employed systematically compared with common process. results showed that addition a...
<i>Objectives:</i> Assessment of the dimensions cardiac chambers and great arteries in human fetus may be helpful prenatal diagnosis congenital heart disease. The purpose this prospective cross-sectional study was to compile normative data fetal measurements early pregnancy. structure examined 136 normal singleton fetuses between 10 17 weeks gestation. <i>Methods:</i> transversal diameter, both ventricular dimensions, interventricular septal thickness, area,...
Poly(ethylene terephthalate) (PET) is well known as a needful part of comfortable and convenient life. However, the massive use PET key issue in contemporary environmental system. Glycolysis transesterification reaction that employs catalyst ethylene glycol (EG) to disintegrate into bis(hydroxyethyl) terephthalate (BHET). impurities are easily generated during glycolysis process, purification product BHET complicated, resulting yellowing recycled (rPET) obtained by repolymerization. In this...
This is a simple expert system designed to allow fast, low cost “a priori” classification of landslide hazards in seismically active tropical areas. It has been created guide decision making where further and more detailed geotechnical investigations should be performed. The input consists 5 factors. A combination three them (slope, lithology soil humidity) define the “intrinsic susceptibility indicator.” Meanwhile, “triggering indicator” results from rainfall seismic intensity provides data...
We systematically screened binary catalysts for synthesis of dimethyl carbonate (DMC) from CO2, CH3OH and ethylene oxide (EO) in the presence H2O by two-step transesterification process, found commercial quaternary ammonium salts/K2CO3, pyridinium salts/K2CO3 KI/K2CO3 were effective DMC with no need separation (EC). Near 100% conversion EO 82% yield obtained under mild reaction conditions. However, imidazolium salts not compatible inorganic alkaline possibly because reactive C(2)–H ring....
