Physical properties of voltage gated pores [PDF]

open access: yes, 2018
Experiments on single ionic channels have contributed to a large extent to our current view on the function of cell membrane. In these experiments the main observables are the physical quantities: ionic concentration, membrane electrostatic potential and

Clausius-Mossotti approximation in the theory of sintered polar materials: A review [PDF]

open access: yesScience of Sintering, 2009
Clausius-Mossotti approximation is extended to describe the measured magnetic moment of an ellipsoidal sample containing magnetic or nonmagnetic ellipsoidal inclusions and magnetic or nonmagnetic matrix. The magnetic field in the matrix and inclusions is

Distribution of defects in lipid membranes. Computer simulation

open access: yesActa Societatis Botanicorum Poloniae, 2014
Based on the Monte-Carlo method, the ten-state Pink model of lipid membrane was completed by the dynamic Kawasaki-type processes of nearest neighbour exchanges of lipid molecules and vacancies in lipid chain lattice.

Poring over pores: nuclear pore complex insertion into the nuclear envelope

open access: yesTrends in Biochemical Sciences, 2013
The nuclear boundary is formed by the nuclear envelope (NE), a double membrane system that establishes a selective barrier between the nucleoplasm and the cytoplasm. Its barrier characteristics are determined by nuclear pore complexes (NPCs); huge protein assemblies that guard nucleocytoplasmic compartmentalization.

SINTERED STEELS FOR PARTS OF HYDRAULIC PUMPS [PDF]

open access: yesFiabilitate şi Durabilitate, 2018
The structure of sintered steel pores and their distribution is described in terms of breaking model. The found correspondence between pore distribution and crack is examined. The most important theoretical problem is to find the correspondence between

Stereological methods in cement-based materials technology: A survey of my research group’s activities during the past half of a century

open access: yesImage Analysis and Stereology, 2019
Four topics of high engineering relevance in which we were involved are introduced herein. Aggregate packing in concrete is of obvious relevance: denser packings lead to reduced cement demands, while modern developments in the (super) high performance ...

pH-Mediated Regulation of Polymer Transport Through SiN Pores [PDF]

open access: yes, 2018
We characterize the pH controlled polymer capture and transport thorough silicon nitride (SiN) pores subject to protonation. A charge regulation model able to reproduce the experimental zeta potential of SiN pores is coupled with electrohydrodynamic ...

Template-Assisted Fabrication of Nanostructured Tin (β-Sn) Arrays for Bulk Microelectronic Packaging Devices

open access: yesMetals, 2018
In this study, uniform and ordered nanostructured arrays of pure tin (Sn) were produced by the chemical pulse plating method in potentiostatic mode. Bottom metalized anodic aluminium oxide templates were used as the substrates for holding nanostructures ...

The use of small angle neutron scattering with contrast matching and variable adsorbate partial pressures in the study of porosity in activated carbons [PDF]

open access: yes, 2012
The porosity of a typical activated carbon is investigated with small angle neutron scattering (SANS), using the contrast matching technique, by changing the hydrogen/deuterium content of the absorbed liquid (toluene) to extract the carbon density at ...

Elucidating mysteries of phase-segregated membranes: Mobile-lipid recruitment facilitates pores' passage to the fluid phase [PDF]

open access: yes, 2018
Phase segregation of multicomponent lipid bilayers leads to, under phase-coexistence conditions, domain formation, featuring delimitation by essentially one-dimensional borders.
