The Falling Factorial Basis and Its Statistical Applications [PDF]

open access: yes, 2014
We study a novel spline-like basis, which we name the "falling factorial basis", bearing many similarities to the classic truncated power basis. The advantage of the falling factorial basis is that it enables rapid, linear-time computations in basis ...

Thermally Assisted Photocatalytic Hydrogen Production Using TiO₂/Cu: Evaluation of Performance and Stability

open access: yesChemCatChem, EarlyView.
Thermal enhancement of TiO2/Cu photocatalysis boosts H2 production from 3,847 µmol g−1 h−1 at 40°C to 10,421 µmol g−1 h−1 at 70 °C. Elevated temperatures improve charge separation and reaction kinetics while maintaining catalyst stability. The synergistic photothermal approach demonstrates Cu/TiO2 as an efficient, noble‐metal‐free system for ...

Pt/TiO2 Prepared by Mechanochemistry Boosts Photocatalytic Production of Hydrogen

open access: yesChemCatChem, EarlyView.
Ball milling enables the rapid synthesis of a Pt/TiO₂ photocatalyst with atomically dispersed Pt, outperforming a conventional Pt‐cluster catalyst (1.3× higher H2 evolution from ethanol). Enhanced activity is attributed to single‐atom stabilization and suppressed surface restructuring, promoting efficient charge separation via Schottky barrier ...

Causal Inference for Multiple Treatments using Fractional Factorial Designs [PDF]

open access: yesarXiv, 2019
We consider the design and analysis of multi-factor experiments using fractional factorial and incomplete designs within the potential outcome framework. These designs are particularly useful when limited resources make running a full factorial design infeasible. We connect our design-based methods to standard regression methods.

H2 Production from Ammonia Borane: Integrating Experiments, Computational Fluid Dynamics, and Statistical Analysis for Predicting and Optimizing Process and Reactor Design

open access: yesChemCatChem, EarlyView.
Ammonia borane is considered a great hydrogen carrier, and when hydrolyzed, it can generate 3 moles of H2. This study highlights the combination of experimental and computational work, such as modeling and statistical analysis, that enables future experimentation by focusing on the parameter with the most profound effect on maximum H2 yield.
