Cement Analysis by the Pressed Powder Method on Benchtop WDXRF According to ASTM C114-11

The 2026 SciX Conference will offer an assortment of short courses during the conference week in Sparks, Nevada. We highlight these courses below.

An upcoming talk at SciX 2026 will explore how spectroscopy is being used to evaluate urban air pollution.

John Philip Walters, Ph.D. (1938-2026), was an analytical chemist who spent 17 years researching the physics of spark-discharge emission spectroscopy at the University of Wisconsin-Madison before moving to St. Olaf College in 1982, where he became best known for pioneering a role-playing undergraduate laboratory model that had students take on professional roles to mirror real analytical-chemistry work. His 1991 three-part series on the approach in Analytical Chemistry earned him the ACS Division of Analytical Chemistry's J. Calvin Giddings Award in 1993, and he continued extending his understand-the-system teaching philosophy into computer-controlled instrumentation well into his later career.

Top content published this week include a new article on bioprocess monitoring, a new “Chemometrics in Spectroscopy” column, and an overview of the latest advancements in laser-induced breakdown spectroscopy (LIBS).

A new laser-based spectroscopic method, developed by researchers at the University of Gothenburg and an EU-funded collaboration, has produced the first high-resolution nuclear-shape measurements of the radioactive actinides fermium and neptunium.
