Low-Temperature-Resistant Elastic Organic Crystals with Variable Amplified Spontaneous Emissions

open access: yes, 2023
In recent times, multitudes of organic crystals exhibiting temperature-dependent emissions have been reported, as temperature influences the electron transition process and/or molecular packing structures.

Influence of temperature on the stability of titanium nanocluster in TiCl3 medium [PDF]

open access: yesMATEC Web of Conferences
South Africa is one of the largest producers of titanium-bearing minerals in the world, accounting for 18% of rutile production and 12% of ilmenite production. However, the country has yet to establish a noticeable advantage in the production of titanium,

Tablet Disintegratability: Sensitivity of Superdisintegrants to Temperature and Compaction Pressure

open access: yesPharmaceutics, 2022
Tablet disintegration is an important pre-requisite for drug dissolution and absorption. The disintegration test is typically conducted at 37 °C, but the intragastric temperature may vary due to meals or fever.

Sharp global nonlinear stability for a fluid overlying a highly porous material [PDF]

open access: yes, 2009
The stability of convection in a two-layer system in which a layer of fluid with a temperature-dependent viscosity overlies and saturates a highly porous material is studied. Owing to the difficulties associated with incorporating the nonlinear advection

Natural convection and the evolution of a reactive porous medium [PDF]

open access: yes, 2011
We describe a mathematical model of buoyancy-driven flow and solute transport in a saturated porous medium, the porosity and permeability of which evolve through precipitation and dissolution as a mineral is lost or gained from the pore fluid. Imposing a
