Nonvolatile room-temperature luminescent molecular liquids are a new generation of organic soft materials. They possess high stability, versatile optical properties, solvent-free fluid behaviour and can effectively accommodate dopant dye molecules. Here we introduce an approach to optimize anthracene-based liquid materials, focussing on enhanced stability, fluorescence quantum yield, colour tun...

In this paper, ZnO nanorod-nanosheet hierarchical structures were fabricated using a facile method on zinc foil and used as flexible photoanodes in dye-sensitized solar cells (DSCs). Compared to nanorods (NRs) obtained by the dissolution-precipitation method, the nanorod-nanosheet (NR-NS) hierarchical structures obtained by a second-step homogeneous precipitation improved the performance of DSC...

Lasing in the green from a distributed feedback (DFB) structure, based upon a second order grating fabricated by replica molding in a dye-doped UV curable polymer, has been demonstrated. For a Bragg grating having a periodicity and depth of 360 ± 2 nm and 78 ± 5 nm, respectively, a coumarin 540-polymer laser operates at 535.6 nm, which is in agreement with calculations of the photonic band diag...

Increasing demands for wearable energy sources and highly flexible, lightweight photovoltaic devices have stimulated the development of textile-structured solar cells. However, the former approach of wire-type solar cell fabrication, followed by weaving of these devices, has had limited success, due to device failure caused by high friction forces and tension forces during the weaving process. ...

In this work, we have prepared three types of aptamer-conjugated Rubpy-doped silica nanoparticles for Human breast carcinoma MCF-7 cells labeling. Probe A is prepared through covalent conjugation between amine-labeled MUC-1 aptamer and carboxyl-modified Rubpy-doped NPs (NPs-aptamer). Probe B is prepared based on the interaction between biotin-labeled MUC-1 aptamer and avidin-conjugated Rubpy-do...

All-optical ultrasound transducers are well-suited for use in imaging during minimally invasive surgical procedures. This requires highly miniaturised and flexible devices. Here we present optical transmitters applications based on modified fibre distal tips which allow larger transmitter element sizes, whilst maintaining small diameter proximal fibre. Three configurations were compared; a 400 ...

Abstract In vivo dosimetry for patient radioprotection is a real challenge concerning new radiotherapy treatments. this study we aim to develop dosimeter based on tissue equivalent material, flexible and adaptable the morphology in order perform complex irradiation beams. Here, report evaluation standard beams of highly composed silicone elastomer containing leucomalachite green as radiochromic...
