Morphologically Uniform Electron Transport Layer Incorporating Conjugated Polymer for Efficient Charge Extraction in Tin Perovskite Solar Cells

open access: yesCarbon Energy, EarlyView.
A compact and morphologically uniform electron transport layer is created by blending PC61BM with a small amount of P3HT. The optimized architecture enables efficient charge extraction and suppresses interfacial recombination, which enhances power conversion efficiency and strengthens long‐term operational stability in tin‐based perovskite solar cells,

Revisiting C4N4 Fluorophore: Theoretical Elucidation of the Origin of Fluorescent Properties of 2,5‐Diaminopyrimidines and Strategic Applications to Pd Detection

open access: yesChemistry – A European Journal, EarlyView.
A compact C4N4 fluorophore—comprising only four carbons and four nitrogens—shows structure‐dependent fluorescence that can be rationalized by TDDFT and AFIR analyses. Rational structural design controls whether emission is turned ON or OFF through computationally identified CI structures.

Synthesis, characterization, and performance of x_MoO3/Z‐22 and x_MoO3/MMP catalysts for biodiesel production

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Methyl transesterification of soybean oil using heterogeneous catalysts for biodiesel production. Abstract The growing global demand for renewable fuels has driven the search for efficient catalysts in biodiesel production. This study presents the synthesis and characterization of x_MoO3/Z‐22 and x_MoO3/MMP heterogeneous catalysts, and evaluates the ...

Bayesian inverse ensemble forecasting for COVID‐19

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

CytoBatchFlagR: A Comprehensive Framework to Objectively Assess High‐Parameter Cytometry Data for Batch Effects

open access: yesCytometry Part A, EarlyView.
ABSTRACT Rapid advancements in mass and flow cytometry technologies have allowed researchers to generate and analyze high‐dimensional single cell datasets, often utilizing upwards of 40 protein markers. Such high‐parameter cytometry is increasingly used in longitudinal immunological studies, but technical variations across experimental batch runs can ...

Dynamic tensile strength and fracture evolution of characteristic shale with bedding and hole using linear regression theory

open access: yesDeep Underground Science and Engineering, EarlyView.
The spiral conical perforations generated during methane in situ explosion fracturing operations lead to tensile fracture propagation in shale reservoirs being governed by the combined effects of impact pressure, bedding, and aperture under explosive loading. Using multiple regression analysis and digital image correlation technology, the mechanisms of
