Apolipoprotein E (apoE) is an important determinant for the uptake of triglyceride-rich emulsions and lipoproteins by the liver, and exerts affinity for both the LDL receptor (LDLr) and a distinct liver-specific recognition site. Our current aim was to assess the mechanism underlying the receptor-specificity of apoE-carrying lipoproteins. Triglyceride-rich… (More)
Organic polar crystals from the donor-acceptor substituted 1,4-diphenybutadiene 1 can generate a short-circuit photocurrent and a photovoltage upon illumination with near UV light. The photocurrent and photovoltage are attributed to a bulk photovoltaic effect. The bulk photovoltaic effect has been known for inorganic polar crystals for decades and can now… (More)
We explore a new approach to organic ferroelectric diodes using a benzene-tricarboxamide (BTA) core connected with C10 alkyl chains to pyrrole groups, which can be polymerized to provide a semiconducting ferroelectric material. The compound possesses a columnar hexagonal liquid crystalline (LC) phase and exhibits ferroelectric switching. At low switching… (More)
Light-driven conductance switching in molecular tunnelling junctions that relies on photoisomerization is constrained by the limitations of kinetic traps and either by the sterics of rearranging atoms in a densely packed monolayer or the small absorbance of individual molecules. Here we demonstrate light-driven conductance gating; devices comprising… (More)
Electroforming of an Al/Al 2 O 3 /polymer/Al resistive switching diode is reported. Electroforming is a dielectric soft-breakdown mechanism leading to hysteretic current– voltage characteristics and non–volatile memory behavior. Electron trapping occurs at early stages of electroforming. Trapping is physically located at the oxide/polymer interface. The… (More)
Janus gold nanoparticles are synthesised via a simple preparation method and behave as amphiphiles self-assembling in water into disk-shaped micelles.
