To achieve performance gains in microelectronics, semiconductor size continues to shrink, with feature sizes now in the sub-10-nm range. The challenges associated with the extreme downscaling of...

Far above an oil pipeline, a drone bobs and weaves. The drone, dispatched by Denver, Colorado-based Project Canary, is collecting high-resolution imaging data of the site, while also scanning for any...

The optical materials selected for an optical system depend upon the application, the required system performance and the environment in which the system is to perform; thus the materials’...

What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...

Single-crystal sapphire has been the material of choice for defense and other applications that require extremely durable optics, but aluminum oxynitride (ALON) and magnesium aluminate (spinel) have...

Designing devices that incorporate ultrathin films is an important means of enhancing yields. However, characterizing ultrathin films provides a challenge for mainstream metrology tools such as...

Laura Fabris shares recent work with and a general outlook on spectroscopy for biomedical applications. She focuses on portable and low-cost implementation used for disease and drug monitoring,...

Multiphoton imaging in neuroscience has much evolved from the initial two-photon microscope that Winfried Denk built in Watt Webb’s lab at Cornell University in the late 1980s, which made the...

Viral pathogens can transmit undetected from person to person, often without apparent symptoms, facilitating rapid spread and underscoring the importance of the development and deployment of...

Raman spectroscopy, a technique predicted in 1923 and discovered in 1928, has revolutionized scientists’ understanding of the molecular world by measuring and quantifying vibrational...

Transition metals are elements found in the d-block of the periodic table, which includes groups 3 to 12. They are characterized by their partially filled d orbitals in the electron configuration....

A reagent is a substance or compound that is used in a chemical reaction to bring about a specific transformation or to detect the presence or absence of another substance. Reagents are employed in...

Rare-earth elements (REEs) are a group of seventeen chemical elements found in the Earth's crust, characterized by their unique properties and scarcity relative to other elements. Despite their name,...

In various fields of science and technology, an active element typically refers to a component or substance that actively participates in or facilitates a process, operation, or reaction. Here are...

-Cell Light Probe -X-ray Photosynthesis -New imec Camera On this week’s show, space rocks rock Earth, a probe emits light in living cells, x-raying photosynthesis, and we learn about a new camera...
