Ammonia is a promising zero-carbon fuel for internal combustion engines; however, its low laminar flame speed makes lean combustion highly sensitive to turbulence and flame development. In this study, an entrainment-based two-zone combustion model is developed for hydrogen-enriched ammonia spark-ignit...

Heat recovery systems (HRS) exist in conceptual configurations which encompass a set of energy-using processes installed on a particular site, a set of waste heat recovery technologies and all potential recirculation of material and energy streams with the overall aim to generate an...

Do shifts into high stock-market volatility foreshadow recessions rather than merely accompany them? Prior work shows volatility rises in downturns and can help short-horizon forecasts, but the timing of discrete volatility regime changes relative to business-cycle turning points is less understo...

This study reports high-performance bamboo-based composites engineered through a biological eco-modification strategy involving targeted lignin depolymerisation. By leveraging guaiacol-enhanced <i>Trametes versicolor</i> pretreatment, we achieved substantial improvements in the mechanical properties and water resistanc...

The integration of robotics has created significant opportunities while simultaneously introduced labour market challenges. The aim of this exploratory research is to investigate the impact of robotic adoption on unemployment in a cross-country context. By presenting a novel theoretical framework ...

Cellulose, the most abundant biopolymer on Earth, offers a sustainable alternative to synthetic materials in biomedical applications. Among cellulose-derived materials, nanocellulose has attracted increasing attention due to its favourable biocompatibility, versatility, and compatibility with advanced fabrication te...

We investigate the partitioning behaviour of a Si-30 wt% Ge alloy solidified from its parent melt, both close to equilibrium and under rapid solidification conditions. Contrary to the isomorphous equilibrium phase diagram, we observe step-mediated partitioning, with a number of discrete, Ge-rich,...

Ammonia is a promising zero‑carbon fuel, yet its application is hindered by low flame speed and high ignition energy. While methanol serves as a high-reactivity additive, its effectiveness strongly depends on operating strategies, particularly under medium-load conditions where chemical enhancement&#x...

Extensive research has characterised developmental dyslexia as a disorder associated with phonological impairment, but increasing evidence suggests that visual processing difficulties may also contribute. Whether visual deficits are evident early in development remains unclear, since most evidence derives ...
