Controlling tunable properties by rolling up two dimensional nanomaterials is an exciting avenue for tailoring the electronic and magnetic properties of materials at the nanoscale. We demonstrate the tailoring of a magnetic nanocomposite through hybridization with magnetic nanomaterials using hexagonal boron nitride (h-BN) templates as an effective way to evolve magnetism for the first time. Boron nitride nanosheets exhibited their typical diamagnetism, but rolled-up boron nitride sheets (called nanoscrolls) clearly have para-magnetism in the case of magnetic susceptibility. Additionally, the FeO NP sample shows a maximum ZFC curve at about 103 K, which indicates well dispersed superparamagnetic nanoparticles. The ZFC curve for the h-BN-FeO NP scrolls exhibited an apparent rounded maximum blocking temperature at 192 K compared to the FeO NPs, leading to a dramatic increase in T. These magnetic nanoscroll derivatives are remarkable materials and should be suitable for high-performance composites and nano-, medical- and electromechanical-devices.

Article Synopsis
- The study uses density functional theory and microkinetic modeling to analyze the growth of hexagonal boron nitride (hBN) on a ruthenium surface, focusing on the process of chemical vapor deposition (CVD).
- Four main stages of the growth process are detailed: adsorption and deprotonation of borazine, dimerization, stabilization of larger borazine polymers, and the formation of nanoporous intermediates.
- Findings highlight the importance of the deprotonation sequence in nanostructure formation and provide insights for producing high-quality hBN monolayers, aligning well with experimental data for temperature variations and precursor exposure.

Boron nitride (BN), renowned for its exceptional optoelectrical properties, mechanical robustness, and thermal stability, has emerged as a promising two-dimensional (2D) material. Reinforcing AZ80 magnesium alloy with BN can significantly enhance its mechanical properties. To investigate and predict this enhancement during hot deformation, we introduce two independent modeling approaches a modified Johnson-Cook (J-C) constitutive model and an Artificial Neural Network (ANN).

Research into flexible solid-state supercapacitors for wearable electronics focuses on achieving high performance and safety. Gel polymer electrolytes (GPEs) are preferred over fully solid-state electrolytes due to their better ionic conductivity while addressing safety concerns associated with liquid electrolytes. This study aims to enhance high-performance gel polymer electrolytes (HP-GPEs) by improving the ion transfer rate of polyvinyl alcohol (PVA) with sulfonated hexagonal boron nitride (known as white-graphene) and exploring how rheology influences ion-conduction within HP-GPEs.
