Additive Manufacture of Diamond:Titanium Hybrid Quantum Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT Additive manufacture represents one of the most advanced techniques for the creation of complex parts for applications as diverse as aerospace and implant surgery. However, a challenge with bespoke manufacture of metal parts is the incorporation of sensor elements in a fashion compatible with the 3D printing process.

Stem cell–based therapies for type 1 diabetes: Progress in differentiation, clinical translation, and immune protection

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Directed differentiation of pluripotent stem cells into functional pancreatic β cells have emerged as a promising strategy for the radical treatment of type 1 diabetes, with preclinical and early clinical evidence demonstrating reversal of hyperglycemia and insulin independence.

Investigation of ionospheric response to a moderate geomagnetic storm over the mid-latitude of Saudi Arabia

open access: yesOpen Astronomy
This study investigated the ionospheric response to a moderate geomagnetic storm recorded on May 14, 2019, with a minimum disturbance storm time (Dst) index of −70-70 nT. Observations from three Global Positioning System (GPS) stations (RFHA, 29.6∘{\text{

Population pharmacokinetic modelling of amoxicillin in human breast milk—A contribution from the ConcePTION project

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Amoxicillin, a widely used β‐lactam antibiotic, requires improved pharmacokinetic characterization during breastfeeding. This study used a population pharmacokinetic (PopPK) approach to model amoxicillin concentrations in breast milk, identify variability sources and estimate infant exposure, applying worst‐case scenarios.

Effect of carbamazepine on the pharmacokinetics of vepdegestrant, a PROteolysis TArgeting Chimera estrogen receptor degrader, in healthy adults

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim To evaluate the effects of carbamazepine, a strong cytochrome P450 (CYP)3A4 inducer, on the pharmacokinetics and safety of vepdegestrant, a PROteolysis TArgeting Chimera estrogen receptor degrader. Methods This was a phase 1, open‐label, fixed‐sequence, two‐period study in healthy adult participants.

Defect engineering for highly efficient and stable perovskite top cells for Si tandems

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Defect passivation in wide‐bandgap perovskites is essential for enabling high‐efficiency and stable perovskite/Si tandem solar cells. Bulk, surface, and buried‐interface passivation strategies focus on suppressing nonradiative recombination, ion migration, and halide segregation, thereby clarifying critical design principles for next‐generation tandem ...

Cooper pair islanding model of insulating nanohoneycomb films [PDF]

open access: yes, 2002
We first review evidence for the Cooper pair insulator (CPI) phase in amorphous nanohoneycomb (NHC) films. We then extend our analysis of superconducting islands induced by film thickness variations in NHC films to examine the evolution of island sizes ...

Reduction of deltaic channel mobility by tidal action under rising relative sea level [PDF]

open access: yes, 2018
As Holocene river deltas continue to experience sea-level rise, sediment carried by distributary channels counteracts delta-plain drowning. Many deltas worldwide are subject to tidal action, which strongly affects the morphology of distributary channels ...
