Atomic Force Microscopy of DNA-CTAB Aggregates [PDF]
Biophysical Journal, 2014 Past studies of DNA-surfactant aggregates involving UV-spectroscopy and gel electrophoresis show that when 20 to 100 base-length oligonucleotides interact with the surfactant CTAB in specific ratios of surfactant to oligonucleotide base, they form aggregates.

Advanced Functional Materials, EarlyView.A well‐modulated CeO2/Fe3C heterostructure is successfully constructed. The electron redistribution induced by CeO2 not only enhances the formation energy of Fe vacancies and hinders the dissolution of Fe but also reduces the energy barrier of the ORR.

A Universal Biomimetic Approach for Making Artificial Antigen‐Presenting Cells for T Cell Activation
Advanced Functional Materials, EarlyView.This study shows a biomimetic silica microcapsule (SMC) fabrication method under mild conditions for making artificial antigen‐presenting cells (aAPCs). Inspired by marine biomineralization, peptide‐mediated biosilicification enables silica shell formation on emulsion templates. The resulting SMCs possess a core–shell structure, controlled fluorescence

Synthesis and properties of lipoamino acid/fatty acid mixtures. Influence of the amphiphilic structure. [PDF]
, 2009 The acylation of amino acids by acid chlorides with from 8 to 12 carbon atoms, in alkaline aqueous medium following Shotten-Baumann reaction, results in sodium salts of Nα-acylamino acids and fatty acids mixture. These lastest are present in proportion

Advanced Functional Materials, EarlyView.The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Synthesis of Hierarchical MOR-Type Zeolites with Improved Catalytic Properties
Molecules, 2021 Hierarchical MOR-type zeolites were synthesized in the presence of hexadecyltrimethylammonium bromide (CTAB) as a porogen agent. XRD proved that the concentration of CTAB in the synthesis medium plays an essential role in forming pure hierarchical MOR ...
