Where Projects Fail: Geospatial Evidence of Delays and Cancellations in Chinese Development Finance
Journal of International Development, EarlyView.ABSTRACT Delays and cancellations can severely undermine the effectiveness of development finance. Yet, little systematic evidence exists on where and why these disruptions occur within the rapidly expanding portfolio of Chinese‐financed development projects in Africa.

Near Surface Geophysics, EarlyView.Abstract The United Kingdom's shallow aquifers offer significant but underdeveloped geothermal energy resource. Seismic methods can help address this by improving the understanding of aquifer heterogeneity and potentially allowing long‐term monitoring of thermal plumes.

Exploring biofiber properties and their influence on biocomposite tensile properties
Polymer International, EarlyView.The study measured the physical, flow and chemical properties of 10 biofibers. It characterized the tensile properties of derived biocomposites and linked them using regression models, showing robust predictive performance. Abstract Biofibers serve as effective reinforcements for neat polylactic acid (PLA) in biocomposites, offering an attractive ...

Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

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.

Optimizing Ball‐Milled Composites for Fast Energy Release Under Shock Compression
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Microparticle additives containing both Al fuel and oxidizer, fabricated by arrested reactive milling (ARM), could potentially increase the power of energetic materials such as HMX because they contain premixed fuel and oxidizer. Optimizing shock reactivity requires exploring a vast parametric space encompassing composition, milling parameters

Pesticide use in integrated pest and pollinator management framework to protect pollinator health
Pest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...
