Using a precisely tuned, ultrafast laser, a Cornell researcher showed that the atomic structure of yttrium titanate could be changed to stabilize its magnetism at temperatures three times higher than ...
An elusive state of matter called superconductivity could be realized in stacks of sheetlike crystals just a few atoms thick, a trio of physicists has determined.
Changes in the grain sizes and flow stresses of AA2014 and AA6063 aluminum alloys subjected to compression tests at high temperatures in various constant compression head speeds were investigated. Wh...
Decomposition of methane over nickel catalyst supported on spherical alumina was investigated using a thermogravimetric apparatus. The reaction products were hydrogen and multi-walled carbon nanotube...
A High Strength Gold Alloy for Use at High Temperatures.
For some aerospace and automotive applications, it has been difficult to produce instrumentation for the harsh environments encountered. Problems include high temperatures, high centrifugal forces, co...
Increase in the proportion of milky white rice kernels (MWK) has seriously affected rice quality in west Japan during the last half-decade. Rising of temperature has been considered to be the primary ...
Effects of temperature at various stages during flower bud development on flowering time and cut flower quality were investigated in summer-to-autumn flowering-type ‘Iwa-no-hakusen’ chrysanthemum. Pla...
With global warming and climate change, high-temperature stress has become a major factor affecting crop growth and yield. Cotton (Gossypium hirsutum L.) crops in the United States experience periods ...
A system was developed measuring x-ray powder diffraction in high magnetic fields up to 5 T and at temperatures from 283 to 473 K. The stability of the temperature is within 1 K over 6 h. In order to ...
The objective of the present study was to determine the survival of two enterohemorrhagic Escherichia coli O157:H7 strains (no. 94 and 402) and a saprophytic E. coli 1 strain at temperatures of 55 and...
Heat induced cis-trans isomerisation of sunflower oils depending on temperature, reaction time and original content of linoleic acid was investigated. The content of isomeric fatty acids was determine...
The experimental test results obtained in the study of steel mechanical proprieties variation in case of high temperatures (fire) are presented. The proprieties are referring to: Young’s modulus, E, t...
Bromination of benzonorbornadiene (1) with sodium bromide in the presence of sodium perborate at room temperature gave only one product, the dibromide 2 produced via Wagner-Meerwein rearrangement. How...
The sorption of water, at 490°C and ca. 23–24 torr, on clay mineral surfaces has been studied using thermogravimetry and infrared absorption spectroscopy. Results from a series of synthetic hectorites...
