Slugs at Low Temperatures [PDF]

open access: yesNature, 1961
DAMAGE by slugs in gardens and farms is usually worst in late autumn and early spring. There are three reasons for this. First, some species are most numerous in winter1. Secondly, alternative foods are scarce, and crop plants such as germinating wheat or the young shoots from delphiniums are sometimes almost the only food available. Thirdly, slugs are

Ultra-low electron temperatures in nanostructured samples [PDF]

open access: yes, 2015
Nanostructured samples, be it semiconducting or metallic ones, have received considerable experimental and theoretical attention due to the manifold of possibilities to investigate fundamental physics. Not only are they viable candidates for realizations

Electric Vehicles Under Low Temperatures: A Review on Battery Performance, Charging Needs, and Power Grid Impacts

open access: yesIEEE Access, 2023
Electric vehicles (EVs) are gaining mainstream adoption as more countries introduce net-zero carbon targets for the near future. Lithium-ion (Li-ion) batteries, the most commonly used energy storage technology in EVs, are temperature sensitive, and their

Low‐Temperature Opacities [PDF]

open access: yesThe Astrophysical Journal, 2005
Previous computations of low temperature Rosseland and Planck mean opacities from Alexander & Ferguson (1994) are updated and expanded. The new computations include a more complete equation of state with more grain species and updated optical constants.

Enhancing Performance of LiFePO4 Battery by Using a Novel Gel Composite Polymer Electrolyte

open access: yesBatteries, 2023
Composite polymer electrolyte (CPE) is expected to have great prospects in solid-state batteries. However, their application is impeded due to the poor interfacial compatibility between CPE and electrodes that result in sluggish ionic transformation ...

Low-Temperature Physics [PDF]

open access: yesNature, 1948
THE great attraction of low temperature physics as a field of research is that so many of the phenomena still lack any fundamental theory, so that the outcome of any new experiment is rarely a foregone conclusion. The outstanding phenomena at present requiring something deeper than ‘phenomen-ologica theories are superconductivity and the properties of ...
