Effect of Oxygen Mole Fraction on Static Properties of Pressure-Sensitive Paint [PDF]

Sensors, Vol. 21, No. 4, 1062 (2021), 2020
The effects of oxygen mole fraction on the static properties of pressure-sensitive paint (PSP) were investigated. Sample coupon tests using a calibration chamber were conducted for polymer-based PSP (PHFIPM-PSP), polymer/ceramic PSP (PC-PSP), and anodized-aluminium PSP (AA-PSP).

Some Magnetic Properties and Magnetocaloric Effects in the High-Temperature Antiferromagnet YbCoC₂

Magnetochemistry, 2023
The YbCoC2 compound, which crystallizes in a base-centered orthorhombic unit cell in the Amm2 space group CeNiC2 structure, is unique among Yb-based compounds due to the highest magnetic ordering temperature of TN=27 K.

Nested order-disorder framework containing a crystalline matrix with self-filled amorphous-like innards

Nature Communications, 2022
The synthesis and characterization of new crystalline-amorphous hybrid materials is challenging. Here, the authors report the preparation of a nested order-disorder framework by applying high pressure to a nested copper chalcogenide Cu12Sb4S13.

Recommendations for blood pressure measurement in humans and experimental animals: Part 1: blood pressure measurement in humans: a statement for professionals from the Subcommittee of Professional and Public Education of the American Heart Association Council on High Blood Pressure Research.

HYPERTENSION, 2005
Accurate measurement of blood pressure is essential to classify individuals, to ascertain blood pressure-related risk, and to guide management. The auscultatory technique with a trained observer and mercury sphygmomanometer continues to be the method of ...

Turbulence without pressure [PDF]

, 1995
We develop exact field theoretic methods to treat turbulence when the effect of pressure is negligible. We find explicit forms of certain probability distributions, demonstrate that the breakdown of Galilean invariance is responsible for intermittency ...

Everything you always wanted to know about metallic hydrogen but were afraid to ask

Matter and Radiation at Extremes, 2020
The hydrogen molecule is made from the first and lightest element in the periodic table. When hydrogen gas is either compressed or cooled, it forms the simplest molecular solid. This solid exhibits many interesting and fundamental physical phenomena.

Are the heliosphere, very local interstellar medium, and local cavity in pressure balance with Galactic gravity [PDF]

, 2022
The Voyager spacecraft are providing the first in situ measurements of physical properties in the outer heliosphere beyond the heliopause. These data, together with data from the IBEX and HST spacecraft and physical models consistent with these data, now provide critical measurements of pressures in the heliosphere and surrounding interstellar medium ...
