Where were Herod the Great's royal alabaster bathtubs quarried?

From the Middle Bronze Age, Egypt played a crucial role in the appearance of calcite-alabaster artifacts in Israel, and the development of the local gypsum-alabaster industry. The absence of ancient calcite-alabaster quarries ...

Improving ion transmission efficiency of mass spectrometers

A recent study by researchers from the Hefei Institutes of Physical Science and published in Analytical Chemistry presents a novel electrostatic field ion funnel focusing technology called direct current (DC)-ion funnel. ...

A highly sensitive SERS substrate for gas sensing

Trace gas sensing is critical for monitoring environmental pollution and detecting volatile organic compounds released from the human body. As a powerful analytical tool for identifying trace molecules, surface-enhanced Raman ...

Ranking nanodevice functionality methods

As the demand for nanodevices grows so too does the need to improve the functionality of such devices, which is vulnerable to changes in the charge distribution, energy levels or conformation. Hence the desire to assess the ...

Team develops quality control for single cell imaging

One size doesn't necessarily fit all when it comes to testing the effects, including cancer and other diseases, of endocrine-disrupting chemicals (EDC) or toxins, which target many factors, including the estrogen receptor ...

When a band falls flat: Searching for flatness in materials

Finding the right ingredients to create materials with exotic quantum properties has been a chimera for experimental scientists, due to the endless possible combinations of different elements to be synthesized.
