The design of two custom sample holders with a spherical cavity for commercial vibrating sample magnetometer systems is described. For such cavities, the magnetization M[over ->] and the internal magnetic field H(i)[over ->] of a sample are both homogeneous. Consequently, the material parameter M(H(i)) of a sample can be determined even for liquids and powders with a high magnetic susceptibility.

Optogenetic experiments rely on the controlled delivery of light to diverse biological systems. Impressive devices have been recently developed to stimulate cells and small animals with multiple wavelengths and intensities. However, existing hardware solutions are often limited to a single sample holder, and their design and cost can further limit scalability.

A holder has been developed that enables electron yield-detected soft X-ray spectroscopy of fully contained samples at low temperature. Crucially, this design uses elements of the sample containment to collect ejected electrons, removing the need to expose samples directly to the vacuum environment of the spectrometer. The design is modular and should be adaptable to a number of different endstation configurations, enabling spectroscopy of air-sensitive, radioactive and vacuum-sensitive (biological) samples.

Burnout in Practicing Neurologists: A Systematic Review and Meta-Analysis.

Neurol Clin Pract

February 2025

Department of Neurology (JG, NA), The Warren Alpert Medical School of Brown University, Providence, RI; Brown University School of Public Health (SG); Department of Neurology (PG), Medical University of South Carolina, Charleston, SC; Departments of Neurology and Radiology (SA-L), University of Texas Southwestern Medical Center, Dallas, TX; The Warren Alpert Medical School of Brown University (KH), Providence, RI; and Department of Public Health Sciences (MJG), Medical University of South Carolina.

Purpose Of Review: Burnout is a context-dependent, global issue among physicians in the medical field who often face job-related stressors, high workloads, and limited or lack of social support or autonomy. Within medicine, neurology is a specialty with high levels of burnout and low levels of work-life satisfaction. We, therefore, conducted this study to evaluate burnout rates among neurologists globally and identify the tools used to evaluate it.

Developing Ag-based surface-enhanced Raman spectroscopy (SERS) sensors for detecting Hg(II) has garnered significant research interest due to their unparalleled selectivity, which is brought by the specific Ag-Hg amalgamation reaction. However, existing sensors perform unsatisfactorily in the trace detection of Hg(II) because the low concentration of Hg(II) does not have the redox potential sufficient to amalgamate with Ag. To address this challenge, a plasmonic MOF SERS sensor is developed, nanoetched Ag@UiO-68-SMe, by integrating the enormous Raman enhancement effects of nanoetched Ag with the selective enrichment function of UiO-68-SMe into single entity.
