Selective Membrane for Non‐Aqueous Electrochemical Flow Cells

open access: yesAdvanced Functional Materials, EarlyView.
Sulfonated fixed charge functionalization is increased to improve the conductivity of a cation exchange membrane in a non‐aqueous electrochemical cell. Based on ex situ analyses, the material achieved the highest selectivity for this type of system to date.

Solvent Induced Disulfide Bond Formation in 2,5-dimercapto-1,3,4-thiadiazole [PDF]

open access: yes, 2007
Disulfide bond formation is the decisive event in the protein folding to determine the conformation and stability of protein. To achieve this disulfide bond formation in vitro, we took 2,5-dimercapto-1,3,4-thiadiazole (DMcT) as a model compound. We found

Preparation of Amidoxime Polyacrylonitrile Chelating Nanofibers and Their Application for Adsorption of Metal Ions. [PDF]

open access: yes, 2013
Polyacrylonitrile (PAN) nanofibers were prepared by electrospinning and they were modified with hydroxylamine to synthesize amidoxime polyacrylonitrile (AOPAN) chelating nanofibers, which were applied to adsorb copper and iron ions. The conversion of the

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Wood Reconfiguration Enables Broadband Blackbody in Large‐Area, Modular, Optically Welded Carbon Constructs

open access: yesAdvanced Functional Materials, EarlyView.
Wood‐based broadband blackbody is achieved by reconfiguration of wood with lignin nanoparticles prior carbonization. Neglectable reflectivity from the visible to infrared wavelengths is obtained by combining thin nanostructures originated from the wood cell walls with long‐range microcavities in the wood lumina.

FT-IR spectroscopy of lipoproteins—A comparative study

open access: yesSpectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2009
FT-IR spectra, in the frequency region 4000-600 cm(-1), of four major lipoprotein classes: very low density lipoprotein (VLDL), low density lipoprotein (LDL) and two subclasses of high density lipoproteins (HDL(2) and HDL(3)) were analyzed to obtain their detailed spectral characterization.
