Enhancing the efficiency of a wavelength-dispersive spectrometer based on a slitless design using a single-bounce monocapillary [PDF]

Journal of Synchrotron Radiation
This paper introduces a novel slit-less wavelength-dispersive spectrometer design that incorporates a single-bounce monocapillary with the goal of positioning the sample directly on the Rowland circle, thereby eliminating the need for a traditional ...

Predictors of Risk Perception Among General Practitioners and Paediatricians Concerning Potential Health Effects of Exposure to Electromagnetic Fields. [PDF]

Bioelectromagnetics
ABSTRACT Scientific evidence for health issues due to exposure to electromagnetic fields (EMF) is limited but there is considerable concern in the population about such effects. Physicians are seen as an important multiplier to the general population.

Research on Angle-Adaptive Look-Ahead Compensation Method for Five-Degree-of-Freedom Additive Manufacturing Based on Sech Attenuation Curve [PDF]

Micromachines
To address over-extrusion and forming defects at path corners caused by path overlap in additive manufacturing, this paper proposes an angle-adaptive look-ahead compensation algorithm based on a Sech attenuation curve.

Operando Measurement of Transition Metal Deposition in a NMC Li-Ion Battery Using Laboratory Confocal Micro-X-ray Fluorescence Spectroscopy. [PDF]

Small
Transition metal dissolution in Li‐ion batteries can lead to reduced battery performance. To monitor elemental migration during cyclization, laboratory confocal micro‐X‐ray fluorescence spectroscopy is used. The investigation of a nickel‐manganese‐cobalt‐oxide (NMC) coin cell during thousands of charging cycles shows increasing Mn deposition in the ...

New Cerebral Microbleeds After Catheter‐Based Structural Heart Interventions: An Exploratory Analysis [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Cerebral microbleeds (CMBs) are increasingly recognized as “covert” brain lesions indicating increased risk of future neurological events. However, data on CMBs in patients undergoing catheter‐based structural heart interventions are scarce ...
