title: Lung toxicity and gene expression changes in response to whole-body inhalation exposure to cellulose nanocrystal in rats

description: Nanomaterials represent a new class of materials with numerous industrial applications. Considering the projected increase in the production and use of nanomaterials, a corresponding increase in occupational exposure to nanomaterials and their resulting adverse health effects should be anticipated among workers. There is substantial evidence in the literature, based on cell culture and animal studies, supporting the potential toxicity and detrimental health effects associated with exposure to nanomaterials. Intervention and/or prevention of adverse health effects associated with occupational exposure to toxic nanomaterials will be a major concern for health providers and regulatory and non-regulatory government agencies as the use of nanomaterials expand. A key element in the intervention and/or prevention of the adverse health effects associated with occupational exposure to toxic nanomaterials is a clear understanding of the molecular mechanisms underlying the pulmonary toxicity induced by nanomaterials.<br><br>Due to its physicochemical and mechanical properties, nanocellulose has found many applications in manufactured goods in the paper and food industry, cosmetics, biomedicine, and pharmaceuticals. There is potential for human exposure to nanocellulose or products that contain nanocellulose both during the production and use of the materials that contain nanocellulose. The objectives of the current study were to determine lung toxicity potential of crystalline nanocellulose (CNC) and the molecular mechanisms underlying the toxicity. A rat inhalation exposure model was employed to determine the lung toxicity potential of CNC. Global gene expression profile in the lung and bioinformatic analysis of the gene expression data were conducted to determine the molecular mechanisms underlying the CNC-induced lung toxicity.

title: MD simulation.zip from Shear-induced amorphization of pure niobium during nano-cutting

description: The amorphization of pure metallic materials remains one of the key unresolved challenges in materials science. In this study, we investigate the amorphization mechanism in a typical pure metal with body-centred cubic (BCC) lattice—niobium (Nb)—under nano-cutting conditions. A sharp single-crystal diamond tool was used to perform the nano-cutting process. Pre-machining microstructural analysis revealed that the niobium exhibited a coarse-grained structure, with grain sizes exceeding 10 µm. Post-processing, a gradient microstructure was observed, featuring grain sizes in the order of hundreds of nanometres. Significantly, amorphous cluster structures were identified both within the bulk and on the surface of the processed material, with the amorphous fraction of niobium atoms estimated at approximately 0.25% and 0.31%, respectively. To elucidate the underlying deformation and amorphization mechanisms, molecular dynamics (MD) simulations were carried out. Theoretical results demonstrate that the nano-cutting process generates extremely high shear strain, predominantly inducing plastic deformation along the close-packed {110} crystal planes. This shear-dominated deformation ultimately leads to the formation of amorphous regions in pure niobium. Our findings present a novel experimental and computational approach to understanding shear-induced amorphization in monometallic systems, providing new insights into the structural evolution and deformation pathways of BCC metals under extreme mechanical loading.

title: Submitted_files_2025_10_10.zip from A review of global tidal stream energy resources

description: This review identifies 426 candidate sites with potentially suitable characteristics for tidal stream energy development, across 19 countries in Europe, the Americas, Asia and Australasia. The most common site assessment quantifies the theoretical resource, which is the maximum amount of total energy that can be extracted. The aggregated theoretical resource estimate, of 1000, TWh/year, from 262 sites (62% of those identified), across 6 countries, is equivalent to 115 GW of continuous annual power. A more informative, albeit less common assessment, considers technical, environmental and economic constraints on energy extraction. New data from UK assessments is presented that indicates relationships between the theoretical and this more practical level of energy extraction, which are used to derive practical levels of electricity generation at other sites across the world. Results indicate a quasi-practical resource of 110 TWh/year from 90 sites (20% of the candidate sites) across the UK, France, Canada, USA, China and New Zealand. When assessed against national/regional electricity production, the UK, Indonesia and New Zealand show the greatest potential to make national-scale electricity supply contributions, whilst France, Canada, USA and China exhibit lower, regional-scale impact potential. Resource estimation is highly sensitive to turbine/array design and constraints, and studies adopt a wide range. Consequently, reported P10 and P90 resource estimates can lie 40% above/below their P50 estimate, respectively. Recommendations are made to characterize this sensitivity of the resource to these drivers.

title: KirigamiProgramme.zip from Folding a tessellated uniform-thick plate into compact stacks

description: Many large deployable rigid arrays for aerospace and civil applications, e.g. solar panels of satellites, reflectarray antennas and foldable bridges, are preferably constructed from identical panels of uniform thickness. Achieving compact packing for easy transportation remains a significant challenge. This paper develops a mathematical framework to determine when a monohedral tessellated surface of uniform thickness can be rigidly folded into two compact stacks. We first divide the planar surface into a tessellation and define the cuts and folds along a Hamiltonian Circuit (HC) planned within the tessellation, producing a loop of panels. We then establish the necessary and sufficient conditions for the panels to be rigidly folded into two stacks. The first condition ensures that the panels can be folded into two equal stacks by making an imaginary cut along one edge and verifying whether the two ends of the resulting chain rejoin after an equal number of folds. The second condition requires the absence of entanglements or twists during folding when the loop is not cut open. The framework is validated through analytical examples and physical prototypes. This work advances the theoretical foundations of kirigami-inspired deployable structures and provides practical design guidelines for compact foldable planar structures.

title: A Projectile Concussive Impact Model Produces Neuroinflammation in Both Mild and Moderate-Severe Traumatic Brain Injury

description: Traumatic brain injury (TBI) is as a major cause of death and disability experienced by nearly 3 million people annually resulting from falls, vehicular accidents, or from being struck by or against an object. While TBIs can range in severity, the majority of injuries are considered to be mild. However, TBI of any severity has the potential to have long-lasting neurological effects including headaches, cognitive/memory impairments, mood dysfunction, and fatigue as a result of neuronal damage and neuroinflammation. The goal of the study was to evaluate the neuroinflammatory and neuronal damage outcomes associated with mild or moderate-severe TBI via the modification of an established closed-head injury model of TBI by varying the material of the projectile. Rats that received TBI using a stainless steel projectile exhibited outcomes strongly correlated to moderate-severe TBI, such as prolonged unconsciousness, impaired neurobehavior, increased risk for hematoma and death, as well as significant neuronal degeneration and neuroinflammation throughout the cortex, hippocampus, thalamus, and cerebellum. In contrast, rats that received TBI with an aluminum projectile exhibited characteristics more congruous with mild TBI, such as a trend for longer periods of unconscious in the absence of neurobehavioral deficits, a lack of neurodegeneration and mild neuroinflammation. Our results indicate that different levels of behavioral, neuroinflammatory, and damage outcomes are associated with differing levels of TBI severity.

title: Shoulder-Assist Exoskeleton Effects on Balance and Muscle Activity During a Block-laying Task on a Simulated Mast Climber

description: Masonry work, a sub-specialty of the construction industry, consists of 
brick and block-laying. Masonry workers often perform these tasks daily 
using an elevated work platform (e.g., mast climbers). Mast climbers are
 elevating equipment used to replace traditional scaffolds. They have 
been available in the United States since the 1980s. Mast climbers are 
capable of handling much greater loads of workers and materials than 
traditional scaffolding. They also make reaching greater heights much 
easier, thereby improving efficiency on construction projects. However, 
working on an unstable work platform at elevation can increase the risks
 of slips, trips and falls, including falls to a lower level. From 1990 
to 2017, there were a total of 35 recorded fatalities associated with 
the use of mast climbers. Of the 35 fatalities, 13 were masonry workers 
(OSHA report). Additionally, working on a mast climber can also create 
awkward working postures due to the confined nature of the workspace. 
Masonry work can be physically demanding. Concrete block can weigh 
between 9-27 kg. The rate of overexertion among masonry workers was 33.4
 per 10,000 FTEs compared to the average rate of 21.5 per 10,000 FTEs in
 all industries (BLS data). Shoulder-assist exoskeletons present an 
attractive possibility to reduce MSD risks in masonry workers if the 
exoskeletons do not cause adverse effects to the workers’ stability and 
balance. <br><br>In this study, we evaluated effects of three models of 
passive shoulder-assist exoskeletons on balance and shoulder muscle 
activity during a masonry task on a simulated mast climbing work 
platform. The balance-related parameters and shoulder muscle activities 
were compared when using or not using the exoskeletons. We want to 
evaluate the hypotheses that the exoskeletons (1) reduce shoulder muscle
 activity and (2) decrease the stability of the workers.<br>
