Host-guest strategy for full-visible-spectrum piezochromism in halogen-bonded organic frameworks

Nature Communications
Full-visible-spectrum piezochromism is vital for advanced anti-counterfeiting and storage device applications, yet remains challenging. Polycyclic aromatic hydrocarbons represent a promising class of piezochromic materials.

Multi--Pressure Polytropes as Models for the Structure and Stability of Molecular Clouds. I. Theory

, 1999
Molecular clouds are supported by thermal pressure, magnetic pressure, and turbulent pressure. Each of these can be modeled with a polytropic equation of state, so that overall the total pressure is the sum of the individual components.

Estimation procedures affect the center of pressure frequency analysis [PDF]

Brazilian Journal of Medical and Biological Research, 2009
Even though frequency analysis of body sway is widely applied in clinical studies, the lack of standardized procedures concerning power spectrum estimation may provide unreliable descriptors. Stabilometric tests were applied to 35 subjects (20-51 years, 54-95 kg, 1.6-1.9 m) and the power spectral density function was estimated for the anterior ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Phase Transitions in Rotating Neutron Stars [PDF]

, 1998
As rotating neutron stars slow down, the pressure and the density in the core region increase due to the decreasing centrifugal forces and phase transitions may occur in the center.

Temperature-induced amorphization in CaCO3 at high pressure and implications for recycled CaCO3 in subduction zones

Nature Communications, 2019
Subduction of oceanic crust introduces huge amounts of carbonates into Earth’s mantle, contributing to the global carbon cycle. Here, based on high-pressure-temperature experiments, the authors present a reversible temperature-induced transition from ...

Pressure-driven crystal symmetry and carrier concentration optimization for superior thermoelectric transport properties in layered AgCrSe2 [PDF]

Matter and Radiation at Extremes
Phase engineering has proven to be an effective strategy for achieving superior thermoelectric performance, while pressure is an excellent means of expanding the phase space of a material. In this paper, the effect of pressure-induced phase transition on
