Amphiphilic Janus dendrimers containing first through third generation (G1-G3) photodegradable hydrophobic blocks were synthesized and their self-assembly in water was studied. While the G1 and G2 systems formed solid aggregates, the G3 system self-assembled to form dendrimersomes. These dendrimersomes were demonstrat…
The GIAO-PBE0/SARC-ZORA(Pt)∪6-31+G(d)(E) (E = main group element) computational protocol without including relativistic and spin-orbit effects is offered here for the accurate prediction of the (195)Pt NMR chemical shifts of a series of cis-(amine)2PtX2 (X = Cl, Br, I) anticancer agents (in total 42 complexes) and cis…
). Due to the pH-sensitive benzoic imine linkages between the DOX moieties and polymeric backbone, DOX could be rapidly released from the micelles at pH 5.8, whereas only a minimal amount of DOX was released at pH 7.4 under the same conditions. The cytotoxicity assay indicates that the OEG-DOX conjugates show cytotoxi…
We fabricated efficient polyaniline (PANI)/buckypaper supercapacitors based on the continuous growth of flexible carbon nanotube (CNT) films and electro-deposition technique.
Gold nanoparticles stabilized by two novel bifunctional fluorenyl thiols, generated <italic>in situ</italic> from 9,9-didodecyl-2,7-bis(acetylthio)fluorene ( <bold>1</bold> ) and 9,9-didodecyl-2,7-bis(acetylthiophenylethynyl)fluorene ( <bold>2</bold> ), exhibit bridged structures which self-assemble in parallel lines.
The coupled effect of Pt and oxygen vacancies makes Pt-H-WO <sub>3</sub> show excellent sensitivity to formaldehyde in light or in the dark.
High-nanofiller-content graphene/natural rubber nanocomposites with high electrical conductivity and excellent mechanical properties have been obtained <italic>via</italic> vacuum-assisted self-assembly.
We report light-responsive, mechanically switchable, photopatternable nanocomposites based on benzophenone-derivatized cellulose nanocrystals (Bp-CNCs).
Graphene quantum dots with visible light absorption of the carbon core: insights from single-particle spectroscopy and first principles based theory Siddharth Ghosh, Manohar Awasthi, Moumita Ghosh et al.-
This study demonstrates a new concept of calibrating surface enhanced Raman scattering (SERS) intensities without using additional substances as an internal standard and explores factors such as laser fluctuation and different Ag substrates, which affect the results of quantitative analyses based on SERS. To demonstra…
We first synthesized ZnO porous ceramics with a giant permittivity of 10 <sup>4</sup> and low dielectric loss using a high pressure treating method.
The spin-crossover equilibrium midpoint temperature (T1/2) in [Fe(3-bpp)2]X2 (3-bpp = 2,6-di{pyrazol-3-yl}pyridine) varies from 259 K when X− = BPh4− to 277 K when X− = Br−, at 10 mM concentrations in an acetone–water solvent mixture.
In this work thermal lens spectrometry (TLS) is applied to investigate the thermo-optical properties of new organometallic compound containing azomethine group, Dichloro bis [2-(2-hydroxybenzylideneamino)-5-methylphenyl] telluride platinum(II), doped polyacrylamide gel using transistor-transistor logic (TTL) modulated…
The richness of the optical properties of covalent polyoxometalate/organic chromophores compounds is reported.
Set them free? Combining a solid catalyst and a solid free-radical scavenger, gives a free-radical oxidation that gives high selectivity even at high concentrations.
Quantum cutting down-conversion has been the subject of intense research activity due to its wide application in optoelectronic devices. However, the energy transfer mechanism behind this down-conversion process is not fully understood. In this work, monodispersed Eu(3+) doped NaYbF4 nanotubes were synthesized by a hy…
Doxorubicin loaded albumin nanoparticles with folic acid receptor-targeted and magnetically-guided functions significantly improve tumor therapy and MRI.
Reaction of PYR-(MgnBu)2, in which PYR is 2,6-[(DIPP)NC(Me)CHC(Me)N-]2-pyridine and DIPP is 2,6-iPr2-phenyl, with (DIPP)NH2BH3 gave PYR-[MgNH(DIPP)BH3]2 (56%) which was characterized by crystal structure determination. Addition of THF resulted in β-H elimination and formation of PYR-[MgNH(DIPP)BH3](MgH)·THF (57%), lik…
A novel label-free fluorescent biosensor platform has been developed for protease activity assay using peptide-templated gold nanoclusters (AuNCs).
