The measurements reveal an ion-selective conductance that vanishes in pores <0.24 nm in diameter—the size of a water molecule—indicating that permeating ions have a grossly distorted hydration shell. Analysis of the current noise power spectral density exposes a threshold, below which the ...
CNT membranes refer to either an open-ended single CNT or an array of vertically-aligned CNTs incorporated across a polymer film. The pioneering work by Hind et al. [14] showed that by matching the tube opening size and its tube entry functionalities to that of the targeted molecule, the ...
If a molecule is smaller than the smallest of the pores in the resin, it will be able to enter the total pore volume. Molecules that enter the total pore volume are eluted last. Samples are eluted isocratically so there is no need to use different buffers during the separation. Watch ...

Label-free characterization of single biomolecules aims to complement fluorescence microscopy in situations where labeling compromises data interpretation, is technically challenging or even impossible. However, existing methods require the investigated
1). The z-dimension was chosen sufficient to prevent interaction of the LCC molecule with two surfaces at the same time. This lead to simulation box sizes \(6.76 \times 6.23 \times 10.91\) nm\(^3\), \(6.52 \times 7.27 \times 10.00\) nm\(^3\), and \(8.52 \times 8.30 \times ...
this also applies to milligrams - in this case, 2500 milligrams per 100,000 milligrams of water. The concentration of this product will range from 2.4 - 2.6%. This information is reported in the lot specific Certificate of Analysis. Please see the link below to review a sample or lot speci...
8. The method of any one of claims 1 to 7 wherein the hydrogel-forming components include biocompatible polymers selected from a group consisting of methacrylated or hydroxyethyl-methacrylated water soluble non-ionic or ionic polysaccharides, methacrylated dextran ("dex-MA"), hydroxyethyl-methacrylated...
where R is the gas molecule constant, T is the thermodynamic temperature; M is the molecular mass of the gas (in moles). At the steady temperature, υ¯ can be a constant for the same kind of gases. In addition, the geometrical factor of the porous body can be expressed as (9-42...
