A number of writers have asserted that interstellar war is much too expensive to wage.63 This probably is not true. On energy considerations alone, war may be rather inexpensive. In an earlier chapter we discussed the dispatch of starliners similar in bulk to the Starship Enterprise. Let us ...
The advantage of such a technique is that with the help of 10-base DNA a very high number of bar codes can be produced and all possible proteomes can be identified. The only limitation on this method is prior knowledge of proteins expressed in single cells (Tune et al., 2016; Pollock ...

They are generally elite fighters, since spacecraft usually can only carry a limited number of them. There will be a "space army", which are usually just the old ground army troops ferried to combat zones on other planets on huge lightly armed troop carriers. Finally there might be a ...
bromide (Supplementary Fig.15). This is attributed to halide ions (e.g., Br−and Cl−) can be used to control the growth of well-defined NSs32. Besides, the concentrations of CA also had to stay within a critical range to fabricate a high-quality RhMo NSs (Supplementary Fig.16)....

Here we report an electrochemical molecular intercalation approach to a new class of stable superlattices in which monolayer atomic crystals alternate with molecular layers. Using black phosphorus as a model system, we show that intercalation with cetyl-trimethylammonium bromide produces monolayer ...
Understanding the atomic structure and structural instability of organic-inorganic hybrid perovskites is the key to appreciate their remarkable photoelectric properties and understand failure mechanism. Here, using low-dose imaging technique by direct-de
Bromine is a halogen element with atomic number 35 and element symbol Br. At room temperature and pressure, it is one of the fewliquid elements. Bromine is known for its brown color and characteristic acrid odor. Here is a collection of facts about the element: Bromine Atomic Data Atomic N...
