The capacity of DCs to capture and process antigen could be modulated by exogenous stimuli was investigated and it was found that DCs respond to tumor necrosis factor alpha, CD40 ligand, IL-1, and lipopolysaccharide with a coordinate series of changes that include downregulation of macropinocytosis and Fc receptors, disappearance of the class II compartment, and upregulation of adhesion and costimulatory molecules.
Magnetic memory of a single-molecule quantum magnet wired to a gold surface.
The road is now open to address individual molecules wired to a conducting surface in their blocked magnetization state, thereby enabling investigation of the elementary interactions between electron transport and magnetism degrees of freedom at the molecular scale.
Quantum tunnelling of the magnetization in a monolayer of oriented single-molecule magnets
The findings prove that the quantum spin dynamics can be observed in SMMs chemically grafted to surfaces, and offer a tool to reveal the organization of matter at the nanoscale.
Electric field controlled magnetic anisotropy in a single molecule.
It is demonstrated that the molecule retains its magnetic properties and, moreover, that the magnetic anisotropy is significantly enhanced by reversible electron addition/subtraction controlled with the gate voltage, suggesting that single-molecule magnetism can be electrically controlled.
Deposition of intact tetrairon(III) single molecule magnet monolayers on gold: an STM, XPS, and ToF-SIMS investigation
The ability of a tetranuclear iron(III) single-molecule magnet functionalized with thioacetyl-terminated ligands to form monolayers on gold has been investigated by a multitechnique approach based on…
Magnetostructural correlations in Tetrairon(III) single-molecule magnets.
The zero-field splitting parameter D of the ground S=5 spin state correlates strongly with the pitch of the propeller gamma, and thus provides a simple link between molecular structure and magnetic behavior.
Single-molecule-magnet carbon-nanotube hybrids.
The assembly of CNT–SMM hybrids using a tailor-made tetrairon(III) SMM, [Fe4(L)2(dpm)6] (1; Hdpm= dipivaloylmethane), designed to graft onto the walls of C NTs is reported.
