LOW TEMPERATURE ELECTRON MICROSCOPY
Annual Review of Biophysics and Bioengineering, 1981In the investigation of biological ultrastructure by electron microscopy the most significant observation to date is a 1 nm repeat in the purple membrane of Halobacterium halobium (73). With a high degree of certainty, the spacing can be ascribed to the inter a-helical separation within bacteriorhodopsin molecules.

Low-temperature bolometer array
Review of Scientific Instruments, 1989The implementation of a 16-channel, low-temperature bolometer linear detector array is described. The detectors are silicon samples, whose surfaces are doped with phosphorus by the technique of ionic implantation. A single digital processor implemented on a common PC both provides the scanning of the array and performs synchronous signal detection from

Metal Low Temperature Brittleness and Low Temperature Machining
Applied Mechanics and Materials, 2011Most metal materials tend to produce brittle fracture at low temperature. Nominal stress of producing brittle fracture is low, generally lower than yield limit. By use of this property, the machinability of the workpiece, tool life and workpiece surface quality can be improved.

Physics Today, 1948
The Shelter Island Conference on Low Temperatures, May 31–June 2, tried to interpret low temperature theory, and make some sense out of superconductivity and liquid helium. London, Onsager, Tisza, Van Vleck, Slater, and various other theorists all had things to say, as did a number of experimentalists.

Abstract Many interesting phenomena connected with quantum effects and low-energy excitations can be investigated at low temperatures. This represents a large field of the physics of superconductors and semiconductors and solid-state physics in general.

Low-temperature methane reactions
Science, 2017Surface Chemistry Methane is a potential feedstock for more valuable products. The strong carbon-hydrogen bonds of methane can be activated by heterogeneous catalysts but often at temperatures that make it difficult to control reactions selectively. Liang et al.
