Textural evolution and phase transformation in titania membranes: Part 2. - Supported membranes [PDF]
, 1993 Nanostructural evolution and phase transformation in supported and unsupported titania membranes have been studied using Raman spectroscopy, X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM).

Plant Physiology, 1972 Spherosomes are bounded by unusual single-line "membranes" which measure 2 to 3.5 nanometers in width, contrasted to the well known tripartite unit-membranes which measure 6 to 8.5 nanometers in over-all thickness. Juxtaposed externally (from the side addressing the hyaloplasm), two spherosomal membranes adjoin to form a thicker single line, but ...

ChemElectroChem, 2022 In fuel cells, the generally low oxygen reduction reactions (ORR) rate at the cathode is a major factor limiting the overall performance of fuel cell, so the development of high‐performance, stable and inexpensive ORR electrocatalysts is a major ...

Graphene-polyelectrolyte multilayer membranes with tunable structure and internal charge [PDF]
, 2020 One great advantage of graphene-polyelectrolyte multilayer (GPM) membranes is their tunable structure and internal charge for improved separation performance. In this study, we synthesized GO-dominant GPM membrane with internal negatively-charged domains,

The SO(32) Heterotic and Type IIB Membranes [PDF]
, 1998 A two dimensional anomaly cancellation argument is used to construct the SO(32) heterotic and type IIB membranes. By imposing different boundary conditions at the two boundaries of a membrane, we shift all of the two dimensional anomaly to one of the ...

Mesoporous SiC-Based Photocatalytic Membranes and Coatings for Water Treatment
Membranes, 2023 Photocatalytically active silicon carbide (SiC)-based mesoporous layers (pore sizes between 5 and 30 nm) were synthesized from preceramic polymers (polymer-derived ceramic route) on the surface and inside the pores of conventional macroporous α-alumina ...
