Toward the Fabrication of Advanced Nanofiltration Membranes by Controlling Morphologies and Mesochannel Orientations of Hexagonal Lyotropic Liquid Crystals

open access: yesMembranes, 2017
Water scarcity has been recognized as one of the major threats to human activity, and, therefore, water purification technologies are increasingly drawing attention worldwide. Nanofiltration (NF) membrane technology has been proven to be an efficient and

Tailoring the gradient ultrafine-grained structure in low-carbon steel during drawing with shear

open access: yesMetalurgija, 2016
Conventional drawing and drawing with shear were conducted on the rods of low-carbon steel. Deformation by simple drawing forms basically a homogenous structure and leads to a uniform change in microhardness along the billet volume.

The subjective metric of remembered colors: A Fisher-information analysis of the geometry of human chromatic memory.

open access: yesPLoS ONE, 2019
In order to explore the metric structure of the space of remembered colors, a computer game was designed, where players with normal color vision had to store a color in memory, and later retrieve it by selecting the best match out of a continuum of ...
