SOLID PROPELLANTS [PDF]

open access: yesRubber Chemistry and Technology, 2019
ABSTRACT Solid propellants are energetic materials used to launch and propel rockets and missiles. Although their history dates to the use of black powder more than two millennia ago, greater performance demands and the need for “insensitive munitions” that are resistant to accidental ignition have driven much research and development over the ...

Solid-state batteries: from ‘all-solid’ to ‘almost-solid’

open access: yesNational Science Review, 2023
The ‘all-solid’ concept is not necessarily the most rewarding target, and ‘almost-solid’ may rather be the most feasible strategy.

Increased diet viscosity by oat β-glucans decreases the passage rate of liquids in the stomach and affects digesta physicochemical properties in growing pigs

open access: yesAnimal, 2020
Rheological properties of digesta play a role in digesta passage kinetics through the gastrointestinal tract, in turn affecting nutrient absorption kinetics.

Role of surface roughness in superlubricity [PDF]

open access: yes, 2006
We study the sliding of elastic solids in adhesive contact with flat and rough interfaces. We consider the dependence of the sliding friction on the elastic modulus of the solids.

Effect of vacuum impregnation temperature on the mechanical properties and osmotic dehydration parameters of apples

open access: yesBrazilian Archives of Biology and Technology, 2008
The effect of sucrose solution temperature on the mechanical properties, water loss (WL), solids gain (SG) and weight reduction (WR) of apples (Fuji var.) treated by vacuum impregnation was studied.

Dynamics of Solid Proteins by Means of Nuclear Magnetic Resonance Relaxometry

open access: yesBiomolecules, 2019
1H Nuclear magnetic resonance (NMR) relaxometry was exploited to investigate the dynamics of solid proteins. The relaxation experiments were performed at 37 °C over a broad frequency range, from approximately 10 kHz to 40 MHz.

Thermodynamical Extension of a Symplectic Numerical Scheme with Half Space and Time Shifts Demonstrated on Rheological Waves in Solids

open access: yesEntropy, 2020
On the example of the Poynting−Thomson−Zener rheological model for solids, which exhibits both dissipation and wave propagation, with nonlinear dispersion relation, we introduce and investigate a finite difference numerical scheme.
