Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

open access: yesAdvanced Science, EarlyView.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Response of an Infant With Presumed Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) to Ketone Supplementation

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) is an autosomal recessive inborn error of metabolism caused by biallelic pathogenic variants in one of three known genes: ETFA, ETFB, and ETFDH. It can cause multisystem dysfunction, including cardiomyopathy in severe cases.

Enrichment of Low-Level Tritium in Groundwater via an Electrolysis Process for Liquid Scintillation Counting Applications

open access: yesGeosciences, 2023
Tritium levels in the groundwater of arid regions are very low; in most cases, these low tritium levels cannot be detected using a conventional liquid scintillation counter (LSC).

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

The Non‐Professional Virtues of the Hospice Volunteer

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Volunteers have long played a significant role in hospice care. Much of the care volunteers provide consists of weekly hour‐long in‐home visits. Home‐visiting hospice volunteers are not professionals, nor are they strangers or intimates. Hospice volunteers will not typically face moral dilemmas, nor be called upon to make dramatic decisions ...
