Wafer‐Scale Self‐Limiting Epitaxy of Bernal‐Stacked Single‐Crystal Boron Nitride

open access: yesSmall, EarlyView.
Wafer‐scale, single‐crystal Bernal‐stacked boron nitride (bBN) bilayers are grown by flow‐modulated MOCVD, where monoatomic Ni step edges on Ni(111) deterministically direct AB stacking. As an ultrathin interlayer, bBN suppresses interfacial scattering and enables robust, nonvolatile polarization switching in MoS2 channels, offering a scalable platform

Record‐Low Compressibility in [N(C2H5)3CH3]FeCl4 Expands Phase Engineering Horizons in Hybrid Molecular Ferroelectrics

open access: yesSmall, EarlyView.
High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

Agglomeration Behavior of Nonmetallic Particles on the Surface of Si‐Killed Liquid Steel Using HT‐CSLM: An In Situ Investigation

open access: yessteel research international, EarlyView.
The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.

Recent advances of non‐invasive sensors for smart wearable respiratory monitoring

open access: yesVIEW, EarlyView.
Respiration contains rich physiological and pathological information, making it one of the most fundamental and continuous vital signs. Respiration monitoring is a non‐invasive and simple, but incredibly powerful, tool for assessing health, managing disease, and tracking fitness.

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

open access: yesVIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...
