The Elements Go to the Movies. The names of many common elements have found their way into the titles of feature films: gold, silver, iron, copper, and lead, for example, appear in hundr... D Taarea,NC Thomas - 《Journal of Chemical Education》 被引量: 0发表: 2010年 From the ...
The x-ray absorption coefficients of the elements with Z=1 to 17 (excluding helium and neon) have been determined for Mo Kα radiation. The values found in the present work are in better agreement with the earlier experimental data of Allen than with the semitheoretical values given in the...
Most of the chemical elements have now been compressed close to or above 100 GPa (1 Mbar) pressure in diamond-anvil cells and the pressure–volume room-temperature isotherms have been measured. We collect these data and use simple lattice-dynamics models to reduce the isotherms to 0 K. We ...
Consumerism extended to all countries continues (and will continue) to "suffocate" the planet. The main questions are whether we will be able to change the situation in the transformation of matter and energy and whether we will succeed in time. It is through a prospective approach that this ...

Elements of game play are incorporated into a productivity application to assist in motivating users to learn features of the productivity application. For example, the elements of game play that are incorporated into learning features of the productivity application may include items such as usage sta...
On the whole, high concentrations of REEs in plants were related to REE concentrations in the soils in which they grow. These observations are promising to evaluate the possible contamination of environment by REEs resulting from their increased usage in modern industry. 展开 ...
摘要: The present invention relates to sandwich elements with at least one predetermined breaking-point at which the sandwich element breaks in the event of an impact. The present invention further relates to the use of such sandwich elements, particularly in the automotive field....
The genome sizes range from 661,708 to 918,293 kb (Fig. 1a, Extended Data Table 1 and Supplementary Table 1). Prominent features of all genomes are 25–54 regions composed of perfect tandem direct repeats (Fig. 1b and Supplementary Table 2) that are novel (Extended Data Fig. 2) ...
