土木工程材料作为支撑国民经济发展的重要基础原材料,虽然取得了长足进步,但也面临转型升级向纵深转折的艰巨任务和严峻挑战。其中,胶凝材料作为土木工程作业中不可或缺的关键性材料,技术提升与转型升级将围绕实现产品从中低端向中高端转型,以及面向特种化、功能化、低碳化转型,如何创造和应用新型胶凝材料已成为现代化建设急需解决的关键问题之一。
A theory of the resonance Stark effect data reported in part 1 (preceding paper in this issue) is developed. The model used involves a weak charge resonance interaction between the excited state of an...
The electronic absorption spectrum of the homodimeric special pair in bacterial photosynthetic reaction centers is greatly modified when one of the bacteriochlorophylls is replaced by a bacteriopheoph...
A complete chemical module has been developed for use in the Meso-NH three-dimensional cloud resolving mesoscale model. This module includes gaseousand aqueous-phase chemical reactions that are anal...
The recent experimental discoveries about excitation energy transfer (EET) in light harvesting antenna (LHA) attract a lot of interest. As an open non-equilibrium quantum system, the EET demands more ...
Mesoporous CuO/CeO2 bimetal oxides were synthesized by a one-pot method using a cationic surfactant CTAB as structure directing agent and Cu(NO3)23H2O, Ce(NO3)6H2O and NaOH as the inorganic precurso...
We applied laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) techniques to make spatial measurements of chemical tracer concentrations in three natural rock types (tuff, sandsto...
In this work, direct and indirect methods for determination of vitamin K3 were developed using differential pulse polarography. The reaction between sulfite and the quinone (Q) form of vitamin K3 was ...
铜离子催化的氧化关环有机反应,用于选择性荧光探测金属铜离子的存在。晶体结构和光谱分析表明,在DPKA的乙腈/水混合溶剂中,引入铜离子可以促使苯并三氮唑类荧光化合物(2)的形成,该反应可以使得溶液的荧光明显增强。而且在滴定溶液里,引入Cu2+螯合剂EDTA,并不能使得溶液的荧光减弱,表明荧光是由有机物2发射的。同时,其他金属离子的引入并不能产生荧光,而且干扰离子的存在也不能使得荧光光谱发生显著改变,...
The ability to scavenge superoxide anion radicals (•O2−) was determined using an oxygen electrode. The method is based on the determination of •O2− generated by the reaction of...
A sequential extraction procedure, a three-step protocol proposed by the Standards, Measurements and Testing programme (SM & T--formerly BCR) of the European Union, was applied to soil samples for the...
Despite environmental and geochemical interests, Cr and Fe have been left beyond the reach of determinations by ICP-MS due to severe interferences originating from Ar. The applicability of a dynamic r...
The ultra high performance liquid chromatography (UHPLC)-UV method for the simultaneous determination of furosemide, saluamine (furosemide metabolite), spironolactone, carnenone (spironolactone active...
Organic microporous materials based on silicon-containing spiroketal and spirothioketal polymers were synthesized via a 1,3-dioxol-forming polymerization reaction between 1,1a,4,4a,5,5a,8, 8a-octahydr...
An ultra-performance liquid chromatography-electrospray tandem mass spectrometry (UPLC-ESI-MS/MS) method was developed to investigate 20(S)-protopanaxadiol (PPD) pharmacokinetics in rats. Rat plasma s...
