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...

Probing the dye-semiconductor interface in dye-sensitized NiO solar cells

The development of p-type dye-sensitized solar cells (p-DSSCs) offers an opportunity to assemble tandem photoelectrochemical solar cells with higher efficiencies than TiO2-based photoanodes, pioneered...

Exploring the evolution and epidemiology of European CC1-MRSA-IV: tracking a multidrug-resistant community-associated methicillin-resistant Staphylococcus aureus clone

This study investigated the evolution and epidemiology of the community-associated and multidrug-resistant Staphylococcus aureus clone European CC1-MRSA-IV. Whole-genome sequences were obtained for 194...

Nanoscopy on the Chea(i)p

Development and evaluation of a hand-held fiber-optic Raman probe with an integrated autofocus unit

Current implementations of fiber-optic Raman spectroscopy probes are frequently based on non-contact probes with a fixed focus and thus and have to precisely maintain the probe-to-sample distance to ensure...
