From Invasion to Innovation: Synthesis and Characterization of Carboxylated Cellulose Nanocrystals from Prosopis Cellulose and Its Evaluation for Copper(II) Removal from Aqueous Solutions

Abstract Prosopis species (mesquite) was used as a lignocellulosic feedstock for producing carboxylated cellulose nanocrystals (CNC) through the ammonium persulfate (APS) oxidation method. The percentage yields of extracted cellulose and CNC were determined to be 40.40 ± 1.23% an...

Rational homotopy type of the embedding maps between total spaces of the projectivization bundles over complex projective spaces

Purpose This paper investigates the embedding maps fn,k:P(En) ↪ P(En+k), where P(En) and P(En+k) are the total spaces of the projectivized tangent bundles over CPn and CPn+k, respectively. We determine the rational homotopy type of the embedding complement C(fn,k). Design/methodo...

A hybrid multi-criteria decision analysis framework for optimal biodiesel feedstock and facility location selection: A case study of Botswana

The development of sustainable biodiesel supply chains in landlocked developing countries like Botswana is constrained by feedstock supply uncertainty, high logistics costs, and the absence of systematic decision-support tools. This study develops and applies a hybrid multi-crite...

Systematic Literature Review: Towards a Relevant Curriculum for the 21st Century Learner in Botswana

This systematic literature review critically examines scholarly discourse from 2018 to 2024 concerning the development of a relevant curriculum for the 21st-century learner in Botswana. It addresses the research problem of aligning formal education with the dynamic socio-economic...

Extended second-order multi-class traffic flow model with the relative drag function

In heterogenous traffic flow the interaction between different vehicle classes play an important role. This article deals with the extension of second order multiclass traffic flow models to accommodate some violation of lane discipline and heterogeneous choice of speeds in a tra...

Advancements in deep learning for early breast cancer detection using artificial intelligence models in low resource settings

Breast cancer remains a leading cause of mortality among women in low- and middle-income countries (LMICs), compounded by fewer radiologists available and resources for diagnosis. A narrative review that summarizes 45 peer-reviewed publications to date from 2018 to 2025 is presen...

Individualization and Purification of Carbon Nanothreads

Notwithstanding the synthesis of many types of carbon nanothreads with different structures, compositions, and theoretical property predictions, the experimental verification of thread properties remains challenging due to a paucity of techniques to disperse as-grown solid-state...
