Nitrogen limitation inhibits marine diatom adaptation to high temperatures.
Ecology Letters, 2019Ongoing climate change is shifting species distributions and increasing extinction risks globally. It is generally thought that large population sizes and short generation times of marine phytoplankton may allow them to adapt rapidly to global change ...

Abstract High temperature is an important means for inorganic syntheses of novel compounds, materials, and high-temperature phases. In this chapter, we highlight the various important aspects in high-temperature inorganic synthesis, along with their recent progress, such as preparation of rare earth compounds and materials at high temperature, sol ...

Giant Piezoelectricity of Ternary Perovskite Ceramics at High Temperatures
Advanced Functional Materials, 2019Here, novel ferroelectric ceramics of (0.95 − x)BiScO3‐xPbTiO3‐0.05Pb(Sn1/3Nb2/3)O3 (BS‐xPT‐PSN) of complex perovskite structure are reported with compositions near the morphotropic phase boundary (MPB), and which exhibit a piezoelectric coefficient d33 =

High-Temperature Microfluidic Lithography
Advanced Materials, 2002The high-temperature microfluidic lithography was studied. A simple approach to improve the performance of microfluidic lithography, which does not act on the increase in the difference between the pressure that drives the capillary motion, but on the temperature-controlled reduction of the polymer viscosity was presented.

The SU(2) part of electroweak gauge theory has sphaleronlike configurations even in its symmetric phase (temperature {ital T}{gt}{ital T}{sub {ital c}}) which mediate baryon-number-violating processes. These sphalerons sit on top of a potential barrier (which we construct explicitly) whose height rises linearly with {ital T}, and always exceeds {ital T}

High temperature superconductivity
Journal of Polymer Science Part C: Polymer Symposia, 1970AbstractThe critical temperature, Tc, for all presently known superconductors does not exceed 21'K. This fact obviously limits the range of applications of superconductivity in technology in a very fundamental way. On the whole, the reason why the value of Tc for “ordinary” superconductors would not exceed 20‐40oK is fairly well understood. At the same

Publisher Summary This chapter presents after a short reminder of thermodynamic definitions, the most commonly used techniques for surface tension measurements with some details of the most interesting of them for high temperature applications. Some recent results on the evaluation of the influence of external factors, like the surrounding atmosphere,

High-temperature superconducting resonators
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1992Preliminary measurements on high-T(c) superconducting resonators are reported and why they are attractive candidates for incorporation in low-noise oscillators is discussed. Some of the important contributions to oscillator noise are reviewed and how they depend on the resonator parameters is shown. A preliminary YBaCu (3)O(7)/LaAlO(3) resonator with a
