Burying the habitat can be done in a number of ways, but it does pose its own problems. Heavy equipment would not be very effective in this low gravity field, if at all—mostly because it wouldn't be heavy. Get a blade full of dirt and your tracks will simply dig out from under ...
Comparably, for semiconductor fabrication, Moore’s law, published in 1965, predicted that the number of transistors in a dense integrated circuit will double about every two years (figure 3). The number of transistors increased from 2,300 in 1971 to 1.5 billion in 2015. Today, computer ...
Beside of a proper LSJ assignment to the atomic levels, the program also supports the full transformation of the wave functions if required for (nonrelativistic) computations. Title of program: Lsj Catalogue number: ADTL Program summary URL: http://cpc.cs.qub.ac.uk/summaries/ADTL Program ...

properties of two-dimensional MoS2 and show that cyclic stretching and releasing of thin MoS2 flakes with an odd number of atomic layers produces oscillating piezoelectric voltage and current outputs, whereas no output is observed for flakes with an even number of layers. A single monolayer flake ...

Metastable phase two-dimensional catalysts provide great flexibility for modifying their chemical, physical, and electronic properties. However, the synthesis of ultrathin metastable phase two-dimensional metallic nanomaterials is highly challenging, mai
Atomic domains with a finite number of atoms are called Cohen-Kaplansky (CK for short) domains, and atomic domains with almost all (= all but a finite number of) atoms prime are called generalized CK domains. — The main result is to characterize generalized CK domains as follows: R is ...
In this method, the short reduction time of Pt (10 s) was vital for the formation of Pt3 clusters. Since the theoretical average coordination number of Pt–Pt bond was 2.0, and the fitting XAFS data of this Pt decorated nanocatalyst was 1.95, indicating the presence of Pt3 clusters. ...
During the hydroformylation, Rh/CoO achieves the optimal selectivity of 94.4% for butyraldehyde and the highest turnover frequency number of 2,065 h−1among the obtained atomic-scale Rh-based catalysts. Mechanistic studies reveal that a structural reconstruction of Rh single atoms in Rh/CoO ...
