The synthesis and characterization of a novel class of highly-metallized, redox-active polyelectrolytes that employ phosphorus as a scaffold for the installation of transition metals is described. Pyrolysis of thin films of the title polyelectrolytes resulted in the production of magnetite crystallites and ill-defined…
There have been different stress-strain definitions to measure the elastic modulus of spongy materials, especially polyvinyl alcohol (PVA) sponge. However, there is no agreement as to which stress-strain definition should be implemented. This study was aimed to show how different results are given by the various defin…
The purposes of this research were to synthesize and characterize star-shaped poly lactide-co-glycolide-β-cyclo-dextrin (PLGA-β-CD) copolymer by reacting L-lactide, glycolide and β-cyclodextrin in the presence of stannous octoate as a catalyst. The structure of PLGA-β-CD copolymer was confirmed with 1H-NMR, 13C-NMR an…
This study aimed at the development of antimicrobial (AM) packaging based on wheat starch incorporated with chitosan and lauric acid as antimicrobial agents. A series of blends with different ratio of starch, chitosan and lauric acid (S:C:LA) were prepared by casting method. Effects of incorporation of antimicrobial a…
Ultraviolet (UV) irradiation was utilized to gradually modify the chemistry and structure of graphene oxide (GO) flakes, as confirmed by XPS and AFM. Ultrathin GO coatings/membranes, made of UV-irradiated flakes, showed tunable underwater oleophobicity. UV-treated, superoleophobic GO membranes exhibited excellent anti…
Edge growth of rhodium and ruthenium–rhodium metals on highly faceted Cu <sub>2</sub> S semiconductor seeds yields a family of nano-inorganic caged hybrid nanoparticles.
Droplet topology of a Janus emulsion in a vegetable oil (VO)/silicone oil (SO)/Tween 80 aqueous solution (Aq) system prepared in a one-step high energy mixing was investigated, mainly by image observation. Quantitative information of the topology was analyzed referring to the curvature of VO/SO interface, the location…
Two new triazole-pyridine-bistetrazolate ligands were synthesized via a versatile procedure that allows for further derivatization; their corresponding homoleptic tris-ligand nona-coordinated lanthanide complexes are highly luminescent in the solid state and in a PVA polymeric matrix with measured values for the lumin…
Information carriers with an unprecedented combination of thermochromic and shape memory properties are presented. The studied material systems may be used in anti-counterfeiting applications.
A simple one-step electro-deposition method was employed for the synthesis of silver dendritic structures with the aid of graphene oxide (GO) modified multi-walled carbon nanotubes (MWCNTs) which are dispersed in an AgNO <sub>3</sub> solution.
nanorods (NR ) 。在阳离子交换以后， nanorod 与更强壮的排放被分解为二 NP。阳离子交换了恐水病的 UCNP 进一步被包含与 poly (氨基酸) 并且成功地申请了指向的癌症房间 UC 光成像。
The most important interface-related quantities determined by band alignment are the barrier heights for charge transport, given by the Fermi level position at the interface. Taking Pb(Zr,Ti)O 3 (PZT) as a typical ferroelectric material and applying X-ray photoelectron spectroscopy (XPS), we briefly review the interfa…
Lithium halides were introduced into the LiNH2–MgH2 system by ball milling the corresponding chemicals under 50 bar of H2 to decrease the dehydrogenation temperature and enhance the dehydrogenation kinetics. The results show that the LiNH2–MgH2–0.05LiBr sample exhibited optimal hydrogen storage performance. The onset…
Superior behavior for supercapacitors highlight the potential applications of CFGC in energy storage issues.
Ultrabright and biocompatible luminescent polymeric nanoparticles were prepared <italic>via</italic> RAFT polymerization of an AIE dye and a zwitterionic monomer.
A novel benzocyclobutene-fimctionalized poly(m-phenylene) was synthesized. This polymer showed good solubility and film-forming ability. When being heated at high temperature, the polymer film converted to an insoluble cross-linked network structure and did not show any cracks. Thermogravimetric analysis of the polyme…
We report the use of actinic light for the photo-thermal enhanced regeneration of CO <sub>2</sub> from capture solutions containing nanoparticles. Regeneration efficiency increased with higher nanoparticle concentrations and initial solution temperatures.
Debye relaxation limits the low temperature and high frequency operations of a polymer-stabilized blue phase liquid crystal.
2D benzo-CMP and aza-CMP sheets and their BN co-doped derivatives possess distinct structural, electronic and transport properties that are notably different from those of graphene.
Drastic change of luminescent QY was found in a serial of guest-tuned lanthanide CPs. An octupolar-like structure lanthanide CP shows a high two-photon luminescence.
