Liquid acid-catalysed fabrication of nanoporous 1,3,5-triazine frameworks with efficient and selective CO2 uptake
New classes of nanoporous organic polymers based on 1,3,5-triazine units (NOP-1–6) were synthesized via a straightforward, methane-sulfonic acid-catalysed, cost-effective Friedel–Crafts reaction of 2,4,6-trichloro-1,3,5-triazine and tetrahedral building blocks. Among them, NOP-3 with a Brunauer–Emmet–Teller (BET) specific surface area up to 894 m2g?1and the total volume exceeding 0.41 m3g?1exh...

Liquid Crystalline Transition and Gel-Sol Transitions for concentrated Microcrystalline Cellulose (MCC)/1-Ethyl-3-Methylimidazolium Acetate (EMIMAc) Solutions
Liquid crystalline (LC) phase transition and gel?sol transition in the solutions of microcrystalline cellulose (MCC) and ionic liquid (1-ethyl-3-methylimidazolium acetate, EMIMAc) have been investigated through a combination of polarized optical microscope (POM) observation and rheological measurements. Molecular LC phase forms at the 10 wt % cellulose concentration, as observed by POM, whereas th...

A cocrystal strategy for the precipitation of liquid 2,3-dimethyl pyrazine with hydroxyl substituted benzoic acid and a Hirshfeld surfaces analysis of them
We here report the cocrystal strategy for the precipitation of liquid 2,3-dimethyl pyrazine (2,3-DMP) with the hydroxyl substituted benzoic acids: salicylic acid (SA), m-hydroxybenzoic acid (MHBA) and p-hydroxybenzoic acid (PHBA) under identical conditions, and obtained three cocrystals (cocrystal 1–3), respectively. Their crystal structures were characterized by single-crystal X-ray diffraction,...

Hemiphasmidic Side-Chain Liquid Crystalline Polymer: From Smectic C Phase to Columnar Phase with a Bundle of Chains as Its Building Block
We synthesized a new hemiphasmidic side-chain liquid crystalline polymer (P-n, n is the number of carbons in alky tail of the side chain, n = 4?12) using free radical polymerization. The side chain of P-n has a biphenyl in the middle, linked to the polystyrene backbone and to the terminal phenyl group with three alkyl tails via only methyleneoxy units. Upon increasing n,...

High tensile strength and high ionic conductivity bionanocomposite ionogels prepared by gelation of cellulose/ionic liquid solutions with nano-silica
Novel bionanocomposite ionogels consisting of an ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate
(EMIMAc), microcrystalline cellulose (MCC) and nano-silica (nano-SiO2) particles with high tensile strength
and high ionic conductivity have been successfully prepared. Dynamic light scattering (DLS) and
transmission electron microscopy (TEM) measurements reveal a homogeneous dispersion of nano-S...

Preparation and morphology of different types of cellulose spherulites from concentrated cellulose ionic liquid solutions
Spherulites of microcrystalline cellulose (MCC) have been prepared by using the vapor precipitation
procedure with proper humidity at various temperatures from concentrated microcrystalline cellulose/
1-allyl-3-methylimidazolium chloride (MCC/AMIMCl) solutions, for which AMIMCl is an ionic liquid, a
good solvent for dissolving MCC. Four different types of MCC spherulites have been investigated by
...

Liquid Crystalline Phase Behavior and Sol–Gel Transition in Aqueous Halloysite Nanotube Dispersions
The liquid crystalline phase behavior and sol?gel transition in halloysite nanotubes (HNTs) aqueous dispersions
have been investigated by applying polarized optical microscopy (POM), macroscopic observation, rheometer, small-angle X-ray
scattering, scanning electron microscopy, and transmission electron microscopy. The liquid crystalline phase starts to form at the
HNT concentration of 1 wt %, and...
