The fundamental flexural guided wave (FFGW) permits ultrasonic assessment of the wall thickness of solid waveguides, such as tubes or, e.g., long cortical bones. Recently, an optical non-contact method was proposed for ultrasound excitation and detec

1-D nanostructured thin-films exhibit, amongst other properties, unique mechanical, electrical, thermal, and optical properties. These depend strongly on several aspects, including size, dimension and density. A thorough characterization of a nanostr

The effect of thermal annealing on electroluminescent (EL) properties of polyfluorene-based organic light-emitting diodes (OLEDs) was studied. Two types of light-emitting layers were investigated: undoped layers made of poly(9,9-di-n-octylfluorenyl-2

In medical near-infrared spectroscopy (NIRS), particularly in the study of the brain, light illumination is commonly realised by lasers or laser diodes (LD). However, the rapid development of high-power light-emitting diodes (HPLED), increased optica

The most commonly used hole transporting layer (HTL) in conventional polymer solar cells is poly(3,4-ethylenedioxythiophene)poly(styrenesulfonate) PEDOT:PSS. The acidic nature of this HTL is responsible for etching of the indium tin oxide (ITO) layer
