Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.

Vickers Microhardness as a Viable Mechanical Property Measurement Technique for High Explosive Materials

Propellants, Explosives, Pyrotechnics, EarlyView.
There are multiple drivers for the development of reliable mechanical property techniques for high explosive (HE) samples, particularly smaller HE samples. While Vickers microhardness is a commonly used technique for mechanical characterization in metals and other materials, there has been little work using this technique for HE materials, particularly

What If Cooking Isn't Chemistry? Examining the Good and the Harm in Metaphorical Connections Between Science and Everyday Activities

Science Education, EarlyView.
ABSTRACT This theoretical paper examines why we make claims like “cooking is chemistry,” what these claims mean, and what good or harm they accomplish. We make three interrelated arguments: First, the relationship between scientific and everyday practices is more complicated and less obvious than is often claimed; second, educators and scientists link ...

Application of Circular Economy Principles to Power Generation: Extending the Life of A Hydropower Plant by Pumped Hydro Energy Storage

Sustainable Development, EarlyView.
ABSTRACT The application of circular economy, which aims to maximize efficiency and reduce waste, to renewable energy sources necessitates, given the intermittent nature of the latter, robust energy storage solutions to ensure grid stability and avoid wasting energy.

How digital platforms affect local entrepreneurial activities: Evidence from the staggered entry of craigslist

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Access to markets is critical for entrepreneurial success, yet many face significant barriers. This study argues that digital platforms functioning as peer‐to‐peer marketplaces can facilitate entrepreneurial activity by improving market access for new ventures.
