DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

PARTICLE TRANSPORT IN SANDSTONES

Proceedings of SPE Annual Fall Technical Conference and Exhibition, 1977
Abstract Particle transport within the Berea, Noxie and Cleveland sandstones having mean pore sizes of 10, 15 and 30 microns, respectively, was studied by injection of aqueous suspensions of sand particles having mean particle sizes of 4, 6 and 7 microns.

Particle Transport in Microchannels

Numerical Heat Transfer, Part B: Fundamentals, 2006
A numerical model for particle transport in microchannel is presented. This article focuses on situations where the sizes of the particles are comparable to the sizes of the channels. The present approach is validated against (1) flow around stationary, (2) flow around forced rotating, (3) flow around freely rotating cylinders and (4) sedimentation of ...

Glutamine transport in submitochondrial particles

American Journal of Physiology-Renal Physiology, 1989
Glutamine transport was studied in submitochondrial particles (SMP) to avoid interference from glutamine metabolism. Phosphate-dependent glutaminase activity in SMP was only 0.04% of that in intact mitochondria. The uptake of glutamine in SMP represented both the transport into vesicles and membrane binding (about one-third of total uptake ...

PARTICLE TRANSPORT IN ROUGH CHANNELS

International Journal of Modern Physics C, 2009
The transport of particles in two-dimensional self-affine rough channels is investigated through numerical simulations. We show how the average transit time depends on the particle Stokes number as well as on the restitution coefficient controlling the collisions with the walls.

Phosphate transport in submitochondrial particles

Biochemical and Biophysical Research Communications, 1974
Summary Submitocondrial particles prepared from bovine heart mitochondria in the presence of CaCl 2 on MnCl 2 take up inorganic phosphate. The reaction is sensitive to mersalyl and to hydrophobic N-benzylmaleimide but is insensitive to N-ethylmaleimide. These findings indicate that the phosphate transport system is oriented asymmetrically.

Transport of sputtered neutral particles

Physical Review E, 1995
The initial deposition rate of sputtered material along the walls of a trench is calculated numerically. The numerical scheme is a nonstatistical description of long-mean-free-path transport in the gas phase. Gas-phase collisions are included by using a ``transition matrix`` to describe the particle motion, which in the present work is from the source ...
