Conventional correlation methods suffer from the slow convergence of electron correlation energies with respect to the size of orbital expansions. This problem is due to the fact that orbital products alone cannot describe the behavior of the exact wave function at short inter-electronic distances. Explicitly correlat…
We have succeeded in controlling the morphology of Wulfingite Zn(OH)2 and Wurtzite ZnO at room temperature without using any template or surface ligand through the alteration of zinc ion molarity and the use of the moderately strong cylcohexylamine Brønsted base as a precipitating agent. The morphology was examined by…

Ultra-thin cobalt oxide has been deposited on the Pt nanoparticles to enhance the metal nanoparticles thermal stability. The thickness of protective Co3O4 coating layer can be accurately controlled around 1nm via atomic layer deposition. The Pt catalytic activity towards CO oxidation has been investigated in a micro f…
Materials with the garnet crystal structure include silicate minerals of importance both in geology, on account of their use in geothermobarometry, and industrially as abrasives. As a consequence of the former, there is considerable published thermodynamic information concerning them. We here examine this thermodynami…
In recent years, increased focus has been placed on the development of timber as a natural renewable construction material. However, there exists significant potential for the development of environmentally friendly engineered structural elements by combining timber based products with other natural materials. Basalt…
Fixed bug with ee_sources() (issue #66) Fixed bug in ee_sensor_agg(). Measurements are typecast correctly. Added support to exclude fields using the exclude argument in `ee_observations(). Seperate fields by commas. Similarly you can request additional fields using the extra argument
采用一步水热共缩合法制备了表面磺酸嫁接的介孔分子筛SO3H-MCM-41,采用XRD、N2吸附-脱附、红外吸收光谱、吡啶吸附红外光谱、酸碱滴定等手段对其物理化学性质进行了表征,考察了SO3H-MCM-41对丙烯酸与异丁烯直接加成反应合成丙烯酸叔丁酯的催化性能,在n（i-Butene）/n（Acrylic acid）=1时,探讨了催化剂制备条件n（Sulfonic acid）/n（Silica）,丙烯酸与异丁烯加成反应条件m（t-Butanol）/m（Acrylic acid）、m（Catalyst）/m（Acrylic acid）和反应温度对反应转化率及产物选择性的影响。结果表明,SO3H-MCM-41表面成功嫁接了磺酸基团,嫁接…
Investigation of crystal structure, dielectric, magnetic and local ferroelectric properties of the diamagnetically substituted (1-x)BiFeO3-xBi (Ti0.5Ni0.5)O3 solid solutions samples have been carried out. The solid solutions have been found to possess a rhombohedrally distorted perovskite structure described by the sp…
A 1-D chain-like POM - based organic-inorganic hybrid compound with the chemical formula of [Ni (en)2]{[Ni (en)2]2[Mo8V8O40(VO4)]}[(NH2)2(C2H4)2NH]2·2H2O (en = ethylenediamine) (1) has been hydrothermally synthesized and structurally characterized by the elemental analysis, and single crystal X-ray diffraction. Compou…
One of the oldest goals across the science is to watch atoms undergo reactions in real time. However, such observations are only meaningful if the object of interest is looked at in its natural environment. For most biological and materials sciences samples, this means in solution phase or dispersed in a liquid. Unfor…
Owing to the superior mechanical properties of Carbon Nanotubes (CNTs), research has been initiated to use this nanomaterial in construction industry. The elastic modulus of CNT is of great importance in order to use CNTs in construction industry.for judicious and effective application of CNT in construction industry…
The metal foil carriers for the catalysts with internal electroheating were studied in the paper. The samples were synthesized by implanting aluminum ions into a stainless foil and a subsequent impregnation with palladium. An important characteristic for the catalysts is the process temperature. That is why, in this r…
5% cement was mixed into the cement stabilized macadam base material, then the cement was replaced by SES-I early strength admixture according to the amount of cement (mass ration) which was 0%, 8%, 10%, 12%, 14% and 16%. The unconfined compressive strength Rc of cement stabilized macadam material was tested during di…
This paper proposes an automatic control strategy of the strip width in cold rolling process. The prediction model for the exit strip width of each stand is established. In addition to the strip width variation of the incoming hot-rolled material between the measured and the pre-set values, the variations of the rolli…
