This paper presents the findings of electron paramagnetic resonance (EPR) spectroscopy experiments conducted on two different samples: 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Manganese Chloride (MnCl2) dissolved in H2O. EPR spectroscopy is used to study the electronic and magnetic properties of paramagnetic materials, providing valuable information about their identity, oxidation and spin states, ligand environments, and interactions with the lattice.

Electron Paramagnetic Resonance (EPR) spectroscopy is a useful analytical technique that provides insight into the chemical nature of a variety of species: complex, inorganic, organic, lattices, free radicals etc. in different states. It is primarily used to understand the identity, oxidation and spin state of the paramagnetic ion(s) in a sample, the nature of ligands, and the interactions of the ion(s) with the lattice. Thus, the technique finds broad biological, biochemical and medical applications. EPR spectral analysis of DPPH (at room temperature) and MnCl2 in aqueous solution (at low temperature) were performed at Prof. Doros Petasis' laboratory at Allegheny College. Properties such as the g-factor, hyperfine coupling constant and linewidth for the two samples have been analysed and discussed.

Motor neuron disease (MND) is a progressive neurological disorder, previously thought to exclusively affect the motor system. However, we now know that cognitive and behavioral change is also a part of the condition. MND exists on a spectrum with frontotemporal dementia (FTD),  with up to  15% of people with  MND  also meeting diagnostic criteria for  FTD. The overlap in symptoms can make diagnosis more difficult, but also offer new opportunities for intervention and treatment. Aim: Our aim is to systematically review the academic literature to explore what behavioral symptoms have been identified as occurring in people with MND, FTD and MND-FTD.

In today's highly competitive academic environment, students often face immense pressure to excel, leading to heightened levels of stress and perfectionism. These psychological constructs– perfectionism and academic stress–have been widely acknowledged as key factors influencing students’ mental well-being and academic performance. While some students thrive under perfectionistic conditions, others experience burnout, anxiety, and declining performance, highlighting the need to better understand how these factors interact. This research study aims to fill these gaps by investigating the impact of adaptive and maladaptive and academic stress on academic performance, examining whether these factors act as enhancers or barriers to success. Using a sample of high school students, data was collected via a self-administered survey that included the Frost Multidimensional Perfectionism Scale (FMPS) to measure perfectionism, the Perceived Stress Scale (PSS) to assess academic stress, and a self-reported GPA to evaluate academics performance. The findings revealed that adaptive perfectionism positively predicts academic performance, while maladaptive perfectionism and academic stress are associated with lower GPA. Gender differences were also observed, with females reporting slightly higher GPAs and stress levels compared to males. These results underscore the importance of fostering adaptive perfectionism and managing academic stress to promote healthier learning environments and improve student well-being.

This study looks at how waves and particles interact in different materials by comparing several mathematical models. By analyzing concepts from classical wave theory, quantum mechanics, and fluid dynamics, we explore how energy moves and changes in solids, liquids, and gases. Using both theoretical analysis and computational simulations, we examine key factors like wave speed, energy transfer, and momentum changes. The results highlight how waves sometimes behave smoothly, like in classical physics, but at smaller scales, quantum effects cause them to act more like particles. This research helps improve our understanding of wave-particle interactions, which could lead to better models for engineering, optics, and material science applications.

Skin grafting is a medical procedure in which a piece of skin is harvested from a donor site and surgically transplanted to a recipient's skin injury site. Although it seems like an ideal solution to heal and protect the injured region, it does have practical and physiological limitations. To address these challenges, 3D bioprinted skin grafts offer a potential solution to create new skin grafts, without the risks associated with extracting skin from donor sites. Three dimensional (3D) skin grafts can be created using a 3D bioprinter and a bioink, containing various cell types, including stem cells. The inclusion of stem cells can provide additional benefits, such as promoting vascularisation, and enhancing hair follicle regeneration at the graft site, ultimately improving the graft‘s long-term function and integration.
