Structured surfaces give rise to novel and potentially useful properties such as controllable wettability and structural colour. Here, we demonstrate structured surfaces via reversible surface…
Continuous wave mirrorless lasing in cholesteric liquid crystals with a pitch gradient across the cell gap.
The observation of lasing in dye doped, one-dimensional (1D) photonic bandgap cholesteric liquid crystal (CLC) structures under both coherent and incoherent CW light excitation opens the possibility of all-organic, compact, tunable CW lasers for display and medical applications.
Giant flexoelectricity in bent-core nematic liquid crystal elastomers
Recently ferroelectric ceramic and bent-core nematic liquid crystals have demonstrated flexoelectricity (coupling between curvature strains to electric polarization) up to 104 times larger than the…
Using O 2 to probe membrane immersion depth by 19 F NMR
A ﬂuorinated detergent, CF 3 (CF 2 ) 5 C 2 H 4 -O-maltose, was reconsti- tuted into a lipid bilayer model membrane system to demonstrate the feasibility of determining solvent accessibility and…
Bent-Core Liquid Crystal Elastomers
Liquid crystal (LC) elastomers with bent-core side-groups incorporate the properties of bent-core liquid crystals in a flexible and self-supporting polymer network. Bent-core liquid crystal…

F fluorinated probes were introduced at selected positions of the transmembrane 1 domain of the intact homotrimer of the integral membrane protein, diacylglycerol kinase, and revealed secondary structure, membrane immersion depth, and regions of the helix in contact with the protein or with the micelle.

Differential relaxation rates may be observed in (19)F-labeled membrane-associated molecules resulting from the addition of apolar oxygen under high pressure, as observed on addition of a membrane surface-associated paramagnetic species.
