"Assessing agglomeration economies in a spatial framework with endogenous regressors" [PDF]

open access: yes
This paper is concerned with the influence of agglomeration economies on economic outcomes across British regions. The concentration of economic activity in one place can foster economic performance due to the reduction in transportation costs, the ready

4D Printing of Polyethylene Glycol‐Grafted Carbon Nanotube‐Reinforced Polyvinyl Chloride–Polycaprolactone Composites for Enhanced Shape Recovery and Thermomechanical Performance

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces polyethylene glycol‐functionalized carbon nanotubes (CNTs) to enhance dispersion, interfacial bonding, and 4D printability in polyvinyl chloride‐PCL nanocomposites. The optimized 4D composite (0.5 wt% CNT) achieves a 25% increase in tensile strength, 95.78% shape fixity, and 5‐s recovery time.

Polypropylene Composites Reinforced With Recycled Waste Cellulosic Fiber/Fine Mixture: The Impact of Cellulose Sieving on Performance

open access: yesJournal of Advanced Manufacturing and Processing, EarlyView.
ABSTRACT This study explores how a sieving step of waste cellulosic fiber and fine (WCFF) mixture affects the performance of WCFF‐loaded polypropylene (PP) composites and whether the separation of fines from fibers offers an added benefit. The WCFF samples were downsized, and four different filler size ranges were sieved using a series of mesh sizes ...

Extracellular Vesicles in Calcium Oxalate Nephrolithiasis: Emerging Biomarkers and Therapeutic Potential

open access: yesAdvanced NanoBiomed Research, EarlyView.
Kidney stones cause significant pain and healthcare costs. Current prediction, diagnosis, and treatment options are limited. Extracellular vesicles (EVs), rich in proteins, lipids, and nucleic acids, offer a promising solution. This review explores the roles of EVs in kidney stone management, highlighting their potential as biomarkers and therapeutic ...
