Advanced Healthcare Materials, EarlyView.Progestin drugs are loaded into a mesoporous silicon dioxide host by melt‐infiltration. Drugs that decompose at or close to their melting point can be loaded by the addition of cholesterol, which acts as a melting point suppressor. High mass loading of the drug is achieved, and dissolution of the composite is controlled by the nanoscale properties of ...

A lattice Boltzmann model for natural convection in cavities [PDF]
, 2013 We study a multiple relaxation time lattice Boltzmann model for natural convection with moment–based boundary conditions. The unknown primary variables of the algorithm at a boundary are found by imposing conditions directly upon hydrodynamic moments ...

Morphogenic Growth 3D Printing
Advanced Materials, EarlyView.I additive manufacturing process exploits the spatial propagation of a polymerization reaction front to produce 3D polymer parts 10× faster and 1000× more energy efficient than the fastest stereolithography. In contrast with existing 3D printing, this morphogenic process is inspired by biological “growth and form” due to the self‐directed propagation ...

Convection in Rotating Spherical Fluid Shells [PDF]
in "Mathematical Aspects of Natural Dynamos", E. Dormy, A.M.
Soward (eds.), Grenoble Sciences and CRC Press, Boca Raton, pp. 119-198,
ISBN-13:978-1-58488-954-0, 2007, 2009 The chapter begins with a description of the annulus model of rotationg convection. The basic equations for the spherical problem are then introduced and the onset of columnar convection in spherical shells is discussed. The onset of inertial mode convection is described which prevails at very low Prandtl numbers.

Instability and Convection in Rotating Porous Media: A Review
Fluids, 2019 A review on instability and consequent natural convection in rotating porous media is presented. Taylor-Proudman columns and geostrophic flows exist in rotating porous media just the same as in pure fluids.

Ultrafast Laser Synthesis of Zeolites
Advanced Materials, EarlyView.The study presents a novel ultrafast laser‐driven synthesis technique for zeolites directly in liquid. Laser pulses create a microscopic reactor that controls reaction kinetics at femto‐ and picosecond timescales. Nonlinear light‐matter interactions drive nucleation and growth, allowing the process to be paused at any stage of self‐assembly.
