Thermometric Based‐Microswimmers with Chemical and Optical Engines
Advanced Intelligent Systems, EarlyView.Temperature sensing at small scales is typically performed using passive luminescent particles. Here, an alternative approach is demonstrated by integrating upconversion thermometry into self‐propelled microswimmers powered by chemical fuels or light. This strategy offers a step toward dynamic thermal sensing at the microscale, relevant to both lab‐on ...

Baseline Characteristics of Pristine Agricultural Pods Biochar
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The valorization of agricultural pod wastes into biochar offers a sustainable pathway for waste management and the development of functional carbonaceous materials. This study comparatively evaluates biochars produced from cocoa, flamboyant, and locust bean pods using an autothermal top‐lit updraft gasifier with retort heating, a system ...

Sustaining Hydrothermal Circulation With Gravity Relevant to Ocean Worlds
Journal of Geophysical Research: PlanetsAbstractSome ocean worlds may sustain active, seafloor hydrothermal systems, but the characteristics and controls on fluid‐heat transport in these systems are not well understood. We developed three‐dimensional numerical simulations, using a ridge‐flank hydrothermal system on Earth as a reference, to test the influence of ocean world gravity on fluid ...
