Journal ArticleDOI
Surface modification and functionalization of metal and metal oxide nanoparticles by organic ligands
TL;DR: In this paper, various possibilities are discussed how nanoparticles can be protected by organic ligands and how these ligands can be used to introduce functionalities, such as grafting of an already functionalized ligand on the nanoparticle surface, exchanging part or all existing ligands on the particle surface, or grafting a ligand in a nanoparticle followed by modification by organic chemical reactions.
Journal ArticleDOI
Aerogels from unaltered bacterial cellulose: application of scCO2 drying for the preparation of shaped, ultra-lightweight cellulosic aerogels.

TL;DR: Bacterial cellulose produced by the gram-negative bacterium Gluconacetobacter xylinum was found to be an excellent native starting material for preparing shaped ultra-lightweight cellulose aerogels.
Journal ArticleDOI
About the interactions between nanoparticles and imidazolium moieties: emergence of original hybrid materials
TL;DR: In the parallel dramatic development of both nanoparticles and ionic liquids for materials chemistry, remarkable synergy was observed when combining nanoparticles with one type of ionic liquid, namely imidazolium moieties as mentioned in this paper.
Journal ArticleDOI
Cellulosic aerogels as ultra-lightweight materials. Part 2: Synthesis and properties.

TL;DR: In this paper, the results reveal that all aerogels obtained from 3% cellulose containing NMMOOH 2 O melts had a largely uniform mesoporousstructure with an average pore size of ;9-12 nm, sur-face area of 190-310 m 2 g -1, but rather low mechanical stabilityexpressed as compressive yield strain of 2.9-5.5%.

TL;DR: In this paper, tetrafluoroborate anion led to monolith ionogels by a simple hydrolytic method, affording highly condensed mesoporous silicas with some fluorinated surface sites.
