Ambient‐Light‐Activated Rewritable Optical Patterning in Transparent Long‐Afterglow Garnet Ceramics

open access: yesLaser &Photonics Reviews, EarlyView.
This work demonstrates sunlight‐activated rewritable optical information storage in transparent long‐afterglow Y3Al2Ga3O12:Ce (YAGG:Ce) garnet ceramics fabricated via solid‐state sintering with tetraethyl orthosilicate (TEOS) as a sintering aid. By integrating ambient‐light operability, reversibility, and high optical clarity in a robust ceramic host ...

Thermodynamics and Entropy Loss in Nanoconfined Chain Polymerization

open access: yesJournal of Polymer Science, EarlyView.
The difference in the entropy change on propagation in nanoconfined and bulk free‐radical polymerizations is 1–2 orders of magnitude larger than the conformational entropy lost in confined SAW simulations. The experimental confinement entropy is also super‐extensive in chain length scaling, suggesting that the difference between experiments and ...

A composite, host‐participatory haustorium links host compatibility to defence bifurcation in Alectra vogelii (Orobanchaceae)

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Parasitic weeds of the family Orobanchaceae are among the most damaging constraints on food production in the tropics, draining water and nutrients from their hosts and threatening the livelihoods of millions of smallholder farmers. Yellow witchweed (Alectra vogelii) can destroy entire legume harvests across sub‐Saharan Africa, where these crops are a ...

Surface Science Insight Note: A Good Figure‐Of‐Merit Does Not Necessarily Yield Accurate Chemical Composition: Outcome of Mixed‐Metal Sulfate XPS Data Peak Fitting Using Nonlinear Least‐Squares Fitting of Peak Models

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT The use of peak models and nonlinear least squares optimization, when applied to highly correlated signals without proper context, is shown to be inadequate for chemical state analysis. However, the use of peak models with physically motivated constraints and sufficient contextual information permits fitting of such models to spectra by ...

Synthesis of Amorphous‐Crystalline Mixture Boron Nitride for Balanced Resistive Switching Operation

open access: yesSmall, EarlyView.
An amorphous–crystalline mixture BN (acm‐BN) is synthesized through low‐pressure chemical vapor deposition, achieving balanced resistive switching with low SET voltage and stable RESET. High‐resolution transmission electron microscopy reveals that BN films are fully amorphous at 930 °C, a mixed amorphous–crystalline phase is achieved at 990 °C.
