Ceiling temperature and low temperature polymerization

Polymer, 1962
The possibility of polymerizing monomers in different phys. states is discussed in terms of the different temp. gradients of the Gibbs free energies of liquid monomer, cryst. monomer, and polymer. The coiling temp., below which polymerization is feasible, depends on the phys. state of the monomer. Crystn.

Metal Low Temperature Brittleness and Low Temperature Machining

Applied Mechanics and Materials, 2011
Most 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.

Low-Temperature Microbiology

1965
Publisher Summary This chapter discusses the low-temperature microbiology in organisms. All activities of living organisms are the result of an intricately coordinated series of metabolic reactions. In order that metabolism can proceed at a satisfactory rate; it is essential that an organism be supplied with heat, which is needed as energy of ...

Sensitive temperature gradiometer for use at low temperatures

Review of Scientific Instruments, 1978
A device capable of very sensitive temperature gradient measurements in the presence of relatively large ambient temperature fluctuations is described. The device uses a pair of ’’matched’’ superconducting thin films in a bridge arrangement, with a SQUID magnetometer probe as the null detector.
