In contrast to conventional fluorescent polymers featured by large conjugation structures, a new class of without any conjugations is gaining great interest in immerging applications beyond the possibility achieve conjugated polymers. Poly(ethylene glycol) (PEG), widely used biomedical fields for long time owing its nontoxicity and nonimmunogenicity, found be fluorescence emissive solid state aqueous solution, though deemed as not numerous reports. Through systematic study under different...
Crystalline carbon nitride powder has been successfully prepared via the liquid–solid reaction between anhydrous C3N3Cl3 and Li3N in benzene at 355 °C 5–6 MPa for 12 h. X-Ray diffraction (XRD) indicated that major part of our brown sample was composed mainly α-C3N4 β-C3N4 with lattice parameters a = 6.49 Å, c 4.70 Å 6.43 2.43 β-C3N4. photoelectron spectra (XPS), Fourier transform infrared spectroscopy (FTIR), electron energy-loss (EELS) energy loss near edge structure (ELNES) strongly...
In a mixed solvent of water and ethanol, polystyrene/titanium dioxide (PSt/TiO2) composite particles core-shell structure were prepared by hydrolysis tetrabutyl titanate in the presence cationic PSt or anionic surface-treated using γ-aminopropyl triethoxysilane. Hollow TiO2 obtained through calcination PSt/TiO2 to burn off core dissolution tetrahydrofuran (THF). An alternative process constituted preheating at 200°C allow partial crystallization followed THF. The outcome thus examined TEM,...
Porous polyurea is synthesized by reacting toluene diisocyanate with water in a water–acetone binary solvent. Materials characterization led to the likely conformations of polymer chains owing presence intensive H-bonding.
A porous polyurea (PPU) was prepared through a simple protocol by reacting toluene diisocyanate with water in binary solvent of water-acetone. Its amine group determined spectrophotometric absorbance based on its iminization p-nitrobenzaldehyde amines. PPU then used as novel polymer support for enzyme immobilization, activation glutaraldehyde followed immobilization an enzyme, lipase from Pseudomonas fluorescens (PFL), via covalent bonding the groups molecules. Influences and concentration...
Abstract Background Very‐low‐field magnetic resonance imaging (VLF‐MRI) plays a significant role in medical diagnosis due to its low cost and light weight. High‐quality MR images are essential for accurate diagnosis. It is urgent explore low‐cost, simple convenient approach boost the signal‐to‐noise ratio (SNR) of VLF‐MRI system make more accurate. Purpose The aim this study was evaluate effect proposed metamaterial resonator on enhancing performance 70 mT system. domino volumetric (DVMR),...
Abstract Copolymers of methacrylic acid (MAA) and poly(ethylene glycol) methyl ether methacrylate (PEGMA) were prepared their cloud points in aqueous solution studied as a function comonomer ratio, pH, presence hydrophobic comonomers. Under acidic conditions, the point falls below 0 °C for copolymers with between 25% to 60% content, because formation H‐bonded ether–acid complexes. The also decreases pH. For equivalent ratios, decreasing PEG chain length, larger number groups. Similarly, upon...
Abstract A theoretical analysis and a morphological prediction of polyacrylate (PA)/polysiloxane (PSi) latex particles with core/shell morphologies were first conducted based on interfacial tensions relative volumes the two polymers in system. The results indicated that normal morphology (PSi/PA), hydrophobic polysiloxane as core hydrophilic shell, can be easily formed. Although inverted (PA/PSi) could not formed most cases, even if fraction volume was larger than 0.872, which is smallest...
Abstract The precipitation polymerization of styrene‐trihydroxymethyl propane triacrylate has been carried out using ethanol and an ethanol/water mixture as the solvent. Uniform microspheres with high monomer conversion are achieved within 4 h, a much shorter time than that reported for divinyl benzene‐styrene in acetonitrile. results clearly demonstrate use water co‐solvent is indeed very effective to promote obtain uniform microspheres. With no under otherwise same experimental conditions,...
Abstract Thermosensitive polymer hydrogel particles with size varying from 480 to 620 nm were prepared through precipitation copolymerization of N -isopropylacrylamide N,N ′-methylenebisacrylamide (MBA) in water ammonium persulfate as the initiator. Only hydrogels without any coagula obtained when MBA concentration monomer mixture was kept between 2.5 and 10.0 wt%; increased concentration, conversion enhanced, increased, their shrinking lessened heated 25°C 40°C. Bovine serum albumin...
Owing to their high specific surface area and low density, porous polymer materials are of great importance in a vast variety applications, particularly as supports for enzymes transition metals. Herein, highly uniform polyurea microspheres (PPM), with size between 200 500 μm, prepared by interfacial polymerization toluene diisocyanate (TDI) water through simple microfluidic device composed two tube lines, one which TDI is flowing merged the other aqueous phase, generating therefore droplets...
