Emissive Liquid Crystalline Boron C,N‐Chelates: Synthesis, Self‐assembly, and Photophysical Properties

open access: yesChemistry – A European Journal, EarlyView.
Novel emissive liquid crystalline boron C,N‐chelates were prepared by integrating mesogenic units into the boron C,N‐core. Depending on the substituent at the boron, stable SmA or N mesophases were achieved while maintaining intense blue emission with excellent quantum yields (61%–100%).

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Biophysical processes of morphogenesis in lizard lungs

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Defect‐Engineered Nested Metallic Cu Clusters Enhance CO2 Photoreduction in Photothermal 2D Plasmonic CuSe

open access: yesEcoEnergy, EarlyView.
Solar‐driven photocatalytic CO2 conversion faces charge dynamics and spectral utilization limits. In this study, the nested Cu/CuSe heterostructure effectively enhances near‐infrared absorption, suppress charge carrier recombination, and improve CO production yield and selectivity through the photothermal–photocatalytic synergy. ABSTRACT Photocatalytic

Boosting Charge Separation in a CdIn2S4/Mo2TiC2 MXene Schottky Heterojunction for Enhanced Photocatalytic Hydrogen Production

open access: yesEcoEnergy, EarlyView.
ABSTRACT Mo2TiC2 MXene was exfoliated in situ using hydrofluoric acid solution and subsequently integrated with CdIn2S4 through physical stirring and grinding. The composite material demonstrated exceptional photocatalytic hydrogen evolution (PHE) activity without the loading of any noble metal co‐catalysts, achieving a hydrogen production rate as high
