Iron(III)‐loaded cation exchange resin: A dual approach for aqueous H2S removal and biogas desulphurization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Left: Desulphurization method application. Right: Novel desulphurization method. Abstract The presence of hydrogen sulphide (H2S) in biogas poses significant environmental and operational challenges due to its corrosive and toxic properties. Thus, this study aimed to develop a dual‐function desulphurization system using a cation exchange resin (CIER ...

Energy Landscapes in Chemical Reactions and Transport

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Curating Structural Sense of Belonging Among Minoritized Students: A Case Study of the Performing Arts

open access: yesNew Directions for Higher Education, EarlyView.
ABSTRACT Understanding collegiate norms and practices that promote sense of belonging among students who have traditionally been raced, gendered, stigmatized, and excluded as the ‘other’ in predominantly white institutions (PWI) is of paramount importance today as these efforts face increasingly antagonistic legislation, state policies, and ...

Impact of Sovereign Debt Maturity on Fiscal Sustainability

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This study is the first to investigate the impact of the term structure of public debt on fiscal sustainability. We adopt the widely used backward‐looking measure of fiscal sustainability—fiscal responsiveness as proposed by Bohn. Using data from De Graeve and Mazzolini and focusing on a sample of 19 most developed countries, we demonstrate ...

Polymer informatics: Integrating data‐driven strategies, advanced machine learning, and automated synthesis for next‐generation polymer design

open access: yesInfoScience, EarlyView.
Designing new polymers for applications such as sustainable plastics, biomaterials, and 3D printing has traditionally been slow and expensive, relying heavily on trial‐and‐error experiments. This review shows how polymer informatics—the integration of large polymer databases, machine‐learning models, and automated robotic synthesis—enables fast ...

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.
