Significance Aquatic organisms are rarely found in amber, but when they occur provide invaluable evidence for the better understanding of amber taphonomy and past ecosystems. We report an ammonite several marine gastropods alongside a mixed assemblage intertidal terrestrial forest floor mid-Cretaceous Burmese amber. Our discovery indicates that was living near dynamic shifting coastal environment. The also provides supporting age which is still debated, represents rare example dating using...
A novel core–shell metal–organic framework coated with a dummy template molecularly imprinted polymer (MOF@DMIP) was synthesized by one-pot bulk polymerization for the detection of pyrraline in food samples. The analogue pyrrolidine-3-carboxylic acid used as because its lower cost, and MIL-101 MOF core owing to numerous inherent advantages, including high chemical hydrothermal stabilities. MIL-101@DMIP detect trace foods solid-phase extraction combined high-performance liquid chromatography....
Hydrophobic CdSe/ZnS quantum dots (QDs) coated with a molecularly imprinted polymer (MIP) sensitized graphene (Gra-QDs@MIP) were prepared through one-pot reverse microemulsion polymerization at room temperature. Gra-QDs@MIP was used as molecular recognition element to construct N(ε)-carboxymethyllysine (CML) optosensor. Graphene platform increase the stability and kinetic binding properties of system. Reverse can anchor silica spheres on surface QDs. This provides functional groups...
Benzotriazole and borate derivatives have long been used as multifunctional additives to lubricants. A novel, environmentally friendly additive ester (NHB), which contains boron, ethanolamine, benzotriazole groups in one molecule, was synthesized by a multi-step reaction, its tribological properties rapeseed oil (RSO) were investigated four-ball tribometer. The hydrolysis stability of the half-time open observation methods, mechanism discussed through Gaussian calculation. novel compound NHB...
Fluorescent molecularly imprinted polymer-coated CdSe/ZnS quantum dots were prepared in an efficient one-step synthesis. Their application as fluorescent nanoparticles for the direct quantification of cholesterol milk was characterized. The used cores to produce fluorescence. polymer shells provided specific binding sites cholesterol. system exhibited good linearity from 0.5 150 µg mL−1, a low detection limit 0.15 and acceptable reproducibility with relative standard deviation 4.2% six...
In order to improve the electrochemical performance of LiFePO4, Li0.99Nb0.01FePO4/C composite materials were synthesized with citric acid coating and Nb2O5 doping. The physical chemistry performances investigated by X-Ray diffraction (XRD) Transmission electron microscope (TEM). results show that has smooth charge-discharge voltage platform, first capacity 151.6 mAh•g-1 (0.1C) no obvious fading after 16 cycles. have favorable high rate discharge performances, 131.6 at 0.5C, 119.8 1.0C 106.2...
The electrochemical polymerization of 1-hydroxy-2-methoxybenzene (HMOB) was performed in boron trifuoride diethyl etherate (BFEE) and a novel conducting polymer poly(1-hydroxy-2-methoxybenzene) (PHMOB) easily electrodeposited. oxidation onset HMOB initiated at 0.97 V versus saturated calomel electrode (SCE). PHMOB films obtained from BFEE showed good thermal stability. NMR studies that the occurred C 4 5 position. Fluorescent spectral indicated doped dedoped were blue emitters, with same...
With the acetates of nickel, manganese and cobalt as raw materials lithium hydroxide precipitation agent, precursor Ni1 / 3 Co1 Mn1 (OH) 2 was first prepared by chemical coprecipitation method, which then mixed ballmilled with certain stoichiometric ratios LiOH∙H2O, ultimately obtained LiCo1/3Mn1/3Ni1/3O2 after calcination process. Single-factor experiment in conjunction XRD, SEM, charge-discharge test, utilized to study influence various factors, including dispersion way precursor, pH value...
In order to investigate the relationship between chemical indexes and hygroscopicity of flue-cured tobacco,the absorption equilibrium moisture content(AEMC) desorption content(DEMC),total sugar,reducing sugar,total nitrogen,nicotine,chlorine,potassium pH seventy-six domestic imported tobacco samples were tested,and simple correlation analysis,gray analysis canonical obtained data carried out.The results indicated that: 1) AEMC DEMC extremely significantly positively correlated with its total...
Collapse of crowm broked out with large water gushing at working face during driving tunnel in Ming Ya Zi tunnel’s right tube. According to engineering geology condition and analysis causes collapse, double-deck prior ductile grouting reinforcement technique was applied tunneling surrounding rock consolidation based on the strong pre-support theory.And result treatment successful.Thus,guiding work collapse by theory proved reasonably effectively.
