High peak and average power delivery from Fully-Aperiodic Large-Pitch-Fiber lasers

Negative curvature hollow core fiber sensor for the measurement of strain and temperature

Three different types of strain and temperature sensors based on negative curvature hollow core fiber (NCHCF) are proposed. Each sensor is produced by splicing a small section of the NCHCF between two...

Short Broadband Fiber Gratings with Low Group Delay

Fiber Bragg gratings (FBGs) are essential optical components, which due to their design flexibility offer numerous prospects for a wide range of applications in fiber laser, sensor, and telecommunication...

Systematic evaluation of particle loss during handling in the percutaneous transluminal angioplasty for eight different drug-coated balloons

Paclitaxel drug coated balloons (DCBs) should provide optimal drug transfer exclusively to the target tissue. The aim of this study was to evaluate the particle loss by handling during angioplasty. A robotic...

Mapping Karakorum, the Capital of the Mongol Empire

Karakorum, the capital of the Mongol Empire in the thirteenth century, provides a perfect case study for urbanism in the steppes. The inner layout and extent of the city have only been poorly understood...

Application of Localized Surface Plasmon Resonance Spectroscopy to Investigate Nano-Bio Interface

The accurate determination of events at the interface between a biological system and nanomaterials is necessary for efficacy and safety evaluation of novel nano-enabled medical products. Investigating...

Development of rapid colorimetric assay for the detection of Influenza A and B viruses

The flu viruses are respiratory pathogens which, according to the World Health Organization (WHO), infect 5–10% of the world population resulting in 3–5 million cases of severe illness and 290,000...

Challenges of using Expansion Microscopy for super-resolved imaging of cellular organelles

Expansion Microscopy (ExM) has been successfully used to improve the spatial resolution when imaging tissues by optical microscopy. In ExM, proteins of a fixed sample are crosslinked to a swellable acrylamide...

A wideband cryogenic microwave low-noise amplifier

A broadband low-noise four-stage high-electron-mobility transistor amplifier was designed and characterized in a cryogen-free dilution refrigerator at the 3.8 K temperature stage. The obtained power dissipation...

Giant refractometric sensitivity by combining extreme optical Vernier effect and modal interference

The optical Vernier effect consists of overlapping responses of a sensing and a reference interferometer with slightly shifted interferometric frequencies. The beating modulation thus generated presents...
