A block copolymer with diselenide bonds in the polymer backbone was reported. This capable of forming micellar aggregates that were responsive to redox stimuli. Compared other aggregates, this type diselenide-containing could be both oxidants and reductants even a solution very low concentration under mild conditions.
Inclusion and exclusion of an azobenzene-containing surfactant with α-cyclodextrin (α-CD) can be used to fabricate photostimulus-responsive vesicle-like aggregates that undergo assembly disassembly reversibly (see picture). The movement α-CD is like a molecular shuttle.
A selenium-containing amphiphilic block copolymer (PEG-PUSe-PEG) with a hydrophobic polyselenide and two hydrophilic poly(ethylene glycol) (PEG) blocks was synthesized via polymerization of toluene diisocyanate (TDI) monoselenide-containing diols subsequent termination PEG monomethylether. PEG-PUSe-PEG is able to self-assemble in aqueous solution form aggregates. Interestingly, it found that the aggregates have good oxidation-responsiveness undergo structural dissociation mild oxidative...
We have fabricated a polymeric superamphiphile based on the electrostatic interaction between double hydrophilic block copolymer of poly(ethylene glycol)-b-acrylic acid (PEG-b-PAA) and selenium-containing surfactant (SeQTA). The superamphiphiles are able to self-assemble form micelles in solution. can be disassembled with addition 0.1% H2O2 because SeQTA is very sensitive oxidation. selenide group oxidized into selenoxide (SeQTA-Ox) by H2O2, which makes more hydrophilic, thus leading...
Das Ein- und Ausfädeln zwischen einem Azobenzol-Amphiphil α-Cyclodextrin (α-CD) kann genutzt werden, um photoresponsive vesikelartige Aggregate zu konstruieren, die sich reversibel bilden auflösen (siehe Bild). Die Bewegung des α-CD auf der Alkylkette Amphiphils entspricht eines molekularen Shuttles.

Ti-doped barium ferrite powders BaFe12-x Ti x O19 (x = 0, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8) were synthesized by the sol-gel method. The phase structure morphology analyzed x-ray diffraction (XRD) scanning electron microscopy, respectively. also studied for their magnetic properties microwave absorption. Results show that ferrites (BFTO) exist in single exhibit hexagonal plate-like structure. anisotropy field Ha of BFTO decreases almost linearly with increase concentration, which leads to...
A simple and effective one-step method is proposed for the fabrication of hollow periodic mesoporous organosilica spheres (HPMOSs). The obtained HPMOSs possess well-defined spherical morphology, uniform tunable particle size, adjustable void structure, radially oriented mesochannels in their shells.
In this paper, we describe the use of block copolymer micelles to incorporate Azo-AOT, an azobenzene-containing amphiphile having a structure suitable for reverse micelle formation and fabrication polyelectrolyte/micelle multilayer films. Interestingly, it is found that PS21−PAA157 can more Azo-AOT molecules than PS115−PAA15 micelles, which different from case incorporation noncharged hydrophobic molecules. Moreover, incorporated into undergoes faster photoisomerization in seems be related...
Ultralight Si 3 N 4 ceramic foams have been successfully prepared through particle‐stabilized method, which is based on the adsorption of in situ hydrophobized particles to liquid/air interface foams. Here, we firstly used a long‐chain surfactant cetyltrimethylammonium chloride render partially hydrophobic. By tailoring concentration and pH values suspensions, wet were stabilized avoid coarsening coalescence. SEM results show that possess single strut walls with elongated β‐Si grains...
Flexible zinc-ion batteries have attracted considerable attention as a promising candidate due to their intrinsic safety, high specific capacity, low cost, and environmental benefits. The choice of electrolyte plays a...
We report on the use of block copolymer micelles polystyrene-b-poly(acrylic acid) (PS-b-PAA) as matrixes for incorporating dibenzyl diselenide. found that water-insoluble diselenide, after being incorporated into micelles, demonstrates glutathione peroxidase (GPx) activity in water. Surprisingly, mimicking system can be adjusted to show higher GPx by increasing ionic strength solution simply upon addition NaCl. Moreover, diselenide is quite stable and maintains its even exposure atmosphere.
Abstract In this study, a facile one‐step method was proposed to prepare pore‐expanded hollow‐structured mesoporous silica spheres. The hollowed spheres, at the same time, expanded mesopores sizes. So not only achieved preparation of hollow spheres by self‐templating strategy but also mesochannels. influences different pore‐expanding agents and reaction time on degree hollowing were investigated. obtained samples possess structure, well‐defined spherical morphology, uniform particle size,...
