Beyond Core‐Periphery: A Multidimensional Typology of Brazilian Regional Inventive Capacity
ABSTRACT The geography of invention in Brazil is characterized by a profound and multi‐polarised structure that extends beyond a simple core‐periphery dichotomy. This paper demonstrates this complexity through a multidimensional analysis of inventive capacity (2000–2023), operationalised along four axes—‘how much’, ‘who’, ‘how’, and ‘what’ is invented ...

Where Can Aluminum Go When Batteries Die?
Battery‐derived aluminum is transformed from contaminated waste into an alloying resource for high‐performance Fe‐based alloys. Through controlled Al content and processing, dual‐phase austenite/ferrite microstructures with TRIP‐like behavior are achieved.

Blood‐Based Lead Biomarkers and Sarcopenia Indicators in Older Adults
ABSTRACT Background Chronic exposure to low levels of lead (Pb) remains a widespread public health issue, especially among older adults. While its neurotoxic and cardiovascular effects are well recognized, its potential role in accelerating age‐related musculoskeletal decline is less understood.

ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...

This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...
