Liquid permeation and chemical stability of anodic alumina membranes.

Beilstein journal of nanotechnology

Petukhov DI, Buldakov DA, Tishkin AA, Lukashin AV, Eliseev AA.
PMID: 28382245
Beilstein J Nanotechnol. 2017 Mar 06;8:561-570. doi: 10.3762/bjnano.8.60. eCollection 2017.

A study on the chemical stability of anodic alumina membranes and their performance in long-term water and organic solvent permeation experiments is reported. Anodic alumina possesses high stability for both protonic and aprotonic organic solvents. However, serious degradation of...

Angew Chem Int Ed Engl. 2015 Feb 02;54(6):1803-7. doi: 10.1002/anie.201409878. Epub 2014 Dec 15.

Manipulation of the self-assembly of magnetic colloidal particles by an externally applied magnetic field paves a way toward developing novel stimuli responsive photonic structures. Using microradian X-ray scattering technique we have investigated the different crystal structures exhibited by self-assembly...

Bragg rods and multiple X-ray scattering in random-stacking colloidal crystals.

Physical review letters

Phys Rev Lett. 2003 Jan 17;90(2):028304. doi: 10.1103/PhysRevLett.90.028304. Epub 2003 Jan 17.

Synchrotron small-angle x-ray diffraction images of random-stacking-induced Bragg scattering rods are obtained in a wide range of wave vectors from a single colloidal crystal. The results reveal a strong multiple scattering effect, which leads to new features in the...

Monitoring the coordination of aluminium during microporous oxide crystallisation by in situ soft X-ray absorption spectroscopy.

Chem Commun (Camb). 2006 Nov 13;(42):4410-2. doi: 10.1039/b610080e. Epub 2006 Sep 06.

An in situ cell, which is capable of obtaining time resolved soft X-ray data (200 eV < E < 3000 eV) under hydrothermal conditions has been developed and used to study the self-assembly processes occurring during microporous aluminophosphate crystallization.

Magnetic-field-induced orientational order in the isotropic phase of hard colloidal platelets.

Physical review. E, Statistical, nonlinear, and soft matter physics

The magnetic-field-induced orientational order in the isotropic phase of colloidal gibbsite [Al(OH)3] platelets is studied by means of optical birefringence and small-angle x-ray scattering (SAXS) techniques. The suspensions display field-induced ordering at moderate field strengths (a few Tesla), which...

Efficient continuous-wave frequency doubling of a tunable CO(2) laser in AgGaSe(2).

Second-harmonic output at 4.6-5.5 mum of the order of 6 mW with a 0.12% external conversion efficiency has been obtained by pumping a AgGaSe(2) crystal with a low-power cw CO(2) laser. The surface damage threshold of AgGaSe(2) for cw...

Piezomagnetic quantum dots.

We study the influence of deformations on magnetic ordering in quantum dots doped with magnetic impurities. The reduction of symmetry and the associated deformation from circular to elliptical quantum confinement lead to the formation of piezomagnetic quantum dots. The...

Double-pionic fusion of nuclear systems and the "ABC" effect: approaching a puzzle by exclusive and kinematically complete measurements.

The ABC effect-a puzzling low-mass enhancement in the pipi invariant mass spectrum, first observed by Abashian, Booth, and Crowe-is well known from inclusive measurements of two-pion production in nuclear fusion reactions. Here we report on the first exclusive and...
