Typical biopolymers, including soybean, casein, γ-poly(glutamic acid) (PGA), agarose and chitosan, were investigated as stabilizers in the synthesis of nanoporous magnetite colloidal nanocrystal clusters (MCNCs) by the hydrolysis and reduction of iron(III) chloride hydrate in ethylene glycol at 200 °C. The cluster siz…
The zero-phonon transition rate for nitrogen-vacancy centers is enhanced by coupling to photonic crystal resonators fabricated in monocrystalline diamond. Autocorrelation measurements on the spectrally filtered zero-phonon line demonstrate coupling of a single emitter.
N-confused porphyrin (NCP) undergoes controlled regioselective phosphorylations at the inner, outer or both carbon atoms of the inverted pyrrole ring. Reactivity centered at the internal carbon atom is enhanced in the Ag(III) NCP's whereas the preference for perimeter substitution is characteristic of free base NCP. T…
Disclination lines in chiral nematic liquid crystals exhibit larger geometrical diversity than their counterparts in ordinary nematics and form rich entangled structures in systems with dispersed colloidal inclusions. Numerous metastable and stable states separated by low energy barriers allow for simple rewiring of t…
A novel one step approach to fabricate superhydrophobic and superoleophilic electrodeposited coatings is reported. By performing additional surface-initiated atom transfer radical polymerization (SI-ATRP) from the coating, a further change in wettability of the substrates to a variety of liquids was observed.
Two linear π-conjugated systems with 1,3-diethyl-1,3,2-benzodiazaborolyl [C(6)H(4)(NEt)(2)B-] as a donor group and dimesitylboryl (-BMes(2)) as acceptor were synthesised with -ethynylene-phenylene- (-C≡C-1,4-C(6)H(4)-, 3) and -ethynylene-thiophene- (-C≡C-2,5-C(4)H(2)S-12) bridges between the boron atoms. An assembly (…
In order to investigate the steric effect of aromatic pendant groups and the electrical bistability in nonconjugated polymers potentially for memory device applications, two π-stacked polymers with different steric structures are synthesized and characterized. They exhibit two conductivity states and can be switched f…
We developed a simple preparation procedure for the protein encapsulated nanoparticle and used the nanoparticle for spatiotemporal activity control of various proteins. We succeeded in the local protein activation within cells by light using the nanoparticle.
In the ethenolysis of the renewable raw material ricinoleic acid methyl ester the valuable oleochemical key substance methyl dec-9-enoate is produced. Detailed optimizations lead to a high conversion and yield of the desired product. Another interesting product, the dec-1-ene-4-ol, is built by this reaction as coprodu…
The new antimonato polyoxovanadate [V(IV)(16)Sb(III)(4)O(42)(H(2)O)](8-) cluster (1a) is the main structural motif of the solvothermally obtained compound {(trenH(2))Zn(tren)}(2)[V(16)Sb(4)O(42)(H(2)O)]·xH(2)O (x = 6-10) (1) (tren = tris(2-aminoethyl)amine). The C(2)-symmetric cluster structure is closely related to t…
Ultra-fine BayCa1-y(ZrxTi1-x)O3 powders, with y = 0.89 and x = 0.10, has been synthesized by solid state reaction route from commercial BaCO3, CaCO3, TiO2 and ZrO2 powders using the high-energy ball milling technique in air at room temperature. Dense BCZT ceramics were prepared by varying the sintering conditions from…
To realize the self-assembly of an arginine-rich peptide sequence of R8GRGDS with tumor-targeting and membrane-penetrating functions, a hydrophobic aliphatic tail (stearic acid, C18) was coupled to its N-terminus to construct surfactant-like peptide-amphiphiles (SLPAs). Through increasing the number of C18 tails to en…
Three-dimensional (3D) flower-like PbTe dendrites have been successfully fabricated in high yield through a simple, facile solvothermal method in the presence of β-cyclodextrin. The as-prepared products were characterized by means of powder X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM),…
In this paper, the phase behaviors and self-assembled structures of a series of liquid crystalline linear-dendritic block copolymers (LDBCs) in the bulk state have been systematically investigated in combination with DSC, POM, SAXS, WAXS, and TEM. The LDBCs consist of a linear poly(ethylene glycol) (PEG) block (degree…
We report here redox reactions between graphene oxide (GO) and mercaptans, which reduces GO to reduced graphene oxide (RGO) and oxidizes mercaptans into disulfides. The reduction processes of GO using various mercaptans as the reducing agents are investigated through XPS, TGA, FT-IR, Raman and EA analysis. The degree…
Herein, we design a facile and green method to synthesize luminescent superparamagnetic nanocomposites with a CdSe/CdS-Fe3O4 structure under mild conditions. This approach was performed in the solution phase at ∼90 °C (Fe3O4) and 60 °C (CdSe/CdS). Fe3O4 nanoparticles, prepared via a simple coprecipitation process, wer…
The new thioantimonate [Ni(en)(tren)]4Sb14S25 (1) (tren = tris(2-aminoethyl)amine, en = ethylendiamine) was synthesized under solvothermal conditions using the complex [Ni(en)3]Cl2 as a structure-directing molecule in a slurry of Sb, S and tren as solvent. Under these reaction conditions two of the three en ligands in…
Carbon nanotubes (CNTs) have excellent mechanical, chemical, and electronic properties, but realizing these excellences in practical applications needs to assemble individual CNTs into larger‐scale products. Recently, CNT fibers demonstrate the potential of retaining CNT′s superior properties at macroscale level. High…
The influence of pristine SWNTs in supramolecular hydrogelation of amphiphilic dipeptide carboxylates is delineated. The developed SWNT-nanohybrids with notable mechanical strength act as a scaffold for superior peroxidase activity of cytochrome c in organic media.
A conductive spinel CuFe 2 O 4 is used to protect the metallic interconnect of solid oxide fuel cells (SOFCs) from oxidation and prevent the cathode from chromium poisoning. It is coated by the sol-gel method on a typical metallic interconnect material of Fe-16Cr alloy and evaluated by oxidation at 800°C for 200 h in…
