Distinguishing scientific results from experimental artifacts

While conducting fieldwork at a lab at Princeton University, Talia Dan-Cohen, associate professor of sociocultural anthropology at Washington University in St. Louis, observed a common but perplexing problem. For her book ...

Developing a better diagnostic nano-probe

Biomarkers are components that may be present in biological samples and are related to specific diseases. Therefore, doctors can analyze biological samples from a patient to check their health condition or to monitor the ...

Tomographic measurement of dielectric tensors

A research team reported the direct measurement of dielectric tensors of anisotropic structures including the spatial variations of principal refractive indices and directors. The group also demonstrated quantitative tomographic ...

Suppressing the Auger recombination process in quantum dots

A Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size. QDs have already been applied ...

Ultra-large single-crystal WS2 monolayer

As silicon based semiconducting technology is approaching the limit of its performance, new materials that may replace or partially replace silicon in technology is highly desired. Recently, the emergence of graphene and ...
