Mechanism of C−F Reductive Elimination from Palladium(IV) Fluorides [PDF]

open access: yes, 2010
The first systematic mechanism study of C−F reductive elimination from a transition metal complex is described. C−F bond formation from three different Pd(IV) fluoride complexes was mechanistically evaluated.

Synthesis of CdS and CdSe nanoparticles by thermolysis of diethyldithio- or diethyldiseleno-carbamates of cadmium [PDF]

open access: yes, 1996
Cadmium sulfide and cadmium selenide nanoparticles have been synthesised by a novel route involving the thermal decomposition of the bisdiethyldithio- or bisdiethyldiseleno-carbamates of cadmium in refluxing 4-ethylpyridine solutions. The nanodispersed

Synthesis and characterization of novel polyimides derived from 4,4’-bis(5-amino-2-pyridinoxy)benzophenone: effect of pyridine and ketone units in the main

open access: yesDesigned Monomers and Polymers, 2017
A diamine monomer, 4,4’-bis(5-amino-2-pyridinoxy)benzophenone, was designed and synthesized, and used to react with commercially different kinds of aromatic dianhydrides to prepare a series of polyimides containing pyridine and ketone units via the ...

Thermal Expansion in Dispersion-Bound Molecular Crystals

open access: yes, 2018
We explore how anharmonicity, nuclear quantum effects (NQE), many-body dispersion interactions, and Pauli repulsion influence thermal properties of dispersion-bound molecular crystals.

Investigations into the assembly behaviour of a 'rigidified': P-carboxylatocalix[4]arene [PDF]

open access: yes, 2019
The p-carboxylatocalix[4]arenes have been shown to be versatile supramolecular building blocks capable of forming a range of bi-layers, capsules and nanoscale tubules in the solid state.

Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

open access: yesAdvanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Synthesis of C-5" and C-6"-modified α-GalCer analogues as iNKT-cell agonists [PDF]

open access: yes, 2015
Alpha-Galactosyl Ceramide (α-GalCer) is a prototypical synthetic ligand of invariant natural killer T (iNKT) cells. Upon presentation by the MHC class I-like molecule CD1d, this glycolipid stimulates iNKT cells to secrete a vast amount of both pro ...
