A direct reaction with liquid bromine was used to prepare bromo fullerene C60 Br14-18. The brominated derivative reacted with previous lyprepared graphene-oxide (hereinafter GO), according to a method described by Hummer. The same method was used to oxidize graphite alone. The prepared graphite fullerene foil was brom…
The U. S. steel industry has reduced its energy intensity per ton of steel shipped by 33% since 1990. However, further significant gains in energy efficiency will require the development of new, transformational iron and steelmaking processes. The Paired Straight Hearth Furnace (PSH) process is an emerging alternative…
This contribution contains data on thermal stability of certain materials whose initial precursor is graphite. Graphite was oxidized separately and in a mixture with fullerene C60. The prepared oxides were processed with vacuum filtration to produce foils and their morphology and thermal stability was described. The g…

Single-crystals of titanium oxide (TiO2) were wrapped in a graphene (G) film by chemical deposition. The morphology, composition and structure of the resulting composite were subsequently characterized by SEM, TEM, XRD and FT-IR analysis. The electrochemical properties of the composites were studied by cyclic voltamme…

采用自蔓延燃烧法制备出Ce掺杂的ATO (Ce-ATO)纳米粉体.利用XRD、SEM对粉体的结构及粒径进行了表征.研究了Ce掺杂量、滴定终点pH值、煅烧温度与煅烧时间对粉体晶型结构与粉体粒度及性能的影响，发现当Ce掺杂量为4%，滴定终点pH为7，在600℃下煅烧2h得到的粉体性能最好.此条件下制备的Ce-ATO粉体晶粒尺寸分布为18~22nm，且Ce-ATO粉体的电阻率为9.72?cm
Special joint systems are obtained by means of mechanical fasteners located in semi-hollow parts of aluminium extruded shapes. The aluminium industry showed great interest on these joints due to many advantages: easiness, simplicity, rapid execution, material optimisation and machining reduction. A typical case of the…
We present a computational scheme for total energy calculations of disordered alloys with strong electronic correlations. It employs the coherent potential approximation combined with the dynamical mean-field theory and allows one to study the structural transformations. The material-specific Hamiltonians in the Wanni…
Se presenta un análisis de desempeño de conmutadores de microondas compuestos, de una entrada y una salida (SPST), diseñados con diodos p-i-n tipo masa con diferentes tipos de materiales semiconductores para las bandas de frecuencia Ku y Ka. Las dos configuraciones de conmutadores compuestos más comunes son aquellos c…
Measuring D -spacing values from collagen fibrils or collagen fascicles with surface curvatures will introduce additional errors. This error might be minimized by studying single collagen fibrils which are parallel to the surface of substrates.
In recent years, window-integrated solar protection systems are used and studied as a promising energy saving technology, both for cold and hot climates. In particular, smart windows, whose optical proprieties in the solar wavelength range can somehow be controlled, show interesting results, especially in reducing the…
Considered clean water in swimming pools, on nonionic and anionic surfactants with special adsorbents. Water purification pools plavatelnyx unique, first of all, because the water contains various types of pollution, which it is exposed. Most of these contaminants are introduced by the users of the swimming pool and t…
We revisit an antiferromagnetic quantum phase transition with $\mathbit{Q}=2{\mathbit{k}}_{F}$, where $\mathbit{Q}$ is an ordering wave vector and ${\mathbit{k}}_{F}$ is a Fermi momentum. Reformulating the Hertz-Moriya-Millis theory within the strong-coupling approach to diagonalize the spin-fermion coupling term and…
Purpose. As a rule secondary silumins are characterized by lower quality than their primary analogues. During manufacture of alloys a large quantity of intermetallides, first of all on the basis of iron, in their structure is ignored. To achieve the optimum level of properties it is necessary to search for ways to ada…
