Fast and slow surfactants in turbulence-driven bubble breakup

Fast and slow surfactants in turbulence-driven bubble breakup

Zhan Rui Wu, Tristan Aurégan, Luc Deike

A stormy patch of water can make bubbles in two very different ways: surfactants may leave the larger bubbles untouched while creating up to five times as many tiny ones. The key is not just what the surfactant is, but how fast it arrives.

Causal Relationship Network of Risk Factors Impacting Workday Loss in Underground Coal Mines

Causal Relationship Network of Risk Factors Impacting Workday Loss in Underground Coal Mines

Shangsi Ren, Xin Meng, Tong Yu, Katherine E. Zychowski, Pedram Roghanchi, Jiantao Pu

When a miner misses work after an injury or illness, the cause may be more than the accident itself. A new analysis maps the chain of conditions that lead to lost workdays underground.

Comparative evaluation of pyrolysis oils derived from lignocellulosic biomass and municipal solid waste as potential bitumen modifiers

Comparative evaluation of pyrolysis oils derived from lignocellulosic biomass and municipal solid waste as potential bitumen modifiers

Bhaswati Bora, Nikhil Saboo, Praveen Kumar, Sonal K. Thengane

What if part of the answer to cleaner roads came from things we usually throw away, or sweep off the ground? This study finds that the source of that waste may matter more than expected.

Effect of printing parameters on extrusion-based additive manufacturing using highly filled CuSn12 filament

Effect of printing parameters on extrusion-based additive manufacturing using highly filled CuSn12 filament

Beatrice Aruanno, Alessandro Paoli, Armando Viviano Razionale, Francesco Tamburrino

Metal parts are usually made with costly, energy-hungry machines. This study asks whether a desktop three-dimensional printer, using a metal-filled plastic filament, can make bronze parts strong enough for real engineering work.

Correlating melt pool geometry with temperature dynamics in laser directed energy deposition with wire: insights and industrial implications

Correlating melt pool geometry with temperature dynamics in laser directed energy deposition with wire: insights and industrial implications

Atieh Sahraeidolatkhaneh, Morgan Nilsen, Fredrik Sikström

When a machine builds a metal part layer by layer, a small pool of molten metal changes shape as the heat changes. This study finds that one simple dimension of that pool can reveal temperature well enough to help control the build.

From Top-Right to User-Right: Perceptual Prioritization of Point-Feature Label Positions

From Top-Right to User-Right: Perceptual Prioritization of Point-Feature Label Positions

Petr Bobák, Ladislav Čmolík, Martin Čadík

When a map places a label beside a location, the choice may feel obvious: put it above and to the right. But users in this study preferred something different, putting the label directly above.

A synthesis of machine learning and internet of things in developing autonomous fleets of heterogeneous unmanned aerial vehicles for enhancing the regenerative farming cycle

A synthesis of machine learning and internet of things in developing autonomous fleets of heterogeneous unmanned aerial vehicles for enhancing the regenerative farming cycle

Faris A. Almalki, Marios C. Angelides

Regenerative farming asks agriculture to do more than produce food: it must also rebuild soil, support living variety, and reduce harm to the climate. This paper asks whether a self-directing fleet of flying machines can help make that practical.

A new benchmark for spatiotemporal fusion of Sentinel-2 and Sentinel-3 OLCI images

A new benchmark for spatiotemporal fusion of Sentinel-2 and Sentinel-3 OLCI images

Meryeme Boumahdi, Ángel García‐Pedrero, Mario Lillo‐Saavedra, Consuelo Gonzalo‐Martín

Satellites face a basic trade-off: one sees Earth often but roughly, another sees detail but less often. This study asks whether their views can be combined into a clearer picture of a changing planet.

Spatiotemporal regulation of the bone immune microenvironment via a ‘Zn2+-quercetin’ hierarchical delivery system for bone regeneration

Spatiotemporal regulation of the bone immune microenvironment via a ‘Zn2+-quercetin’ hierarchical delivery system for bone regeneration

Huishan Sun, Yedan Chen, Xiaoqin Sang, Qing‐Xiang Liu, Haoran Yu, Shaojun Hu, Yingji Mao, Li Zhang

Repairing a large bone gap is not just a construction problem. This study suggests the repair material may also need to coach the immune system, quietly at first, then more strongly as healing unfolds.

Behaviour and Microstructural Characteristics of Lime-GGBS-Treated Kaolin Clay Contaminated with Gypsum

Behaviour and Microstructural Characteristics of Lime-GGBS-Treated Kaolin Clay Contaminated with Gypsum

Jeremiah J. Jeremiah, Samuel J. Abbey, Colin A. Booth, Anil Kashyap

A road can fail not because its soil is too weak, but because the repair material makes it swell. This study finds a different mixture that strengthens the ground while sharply reducing that dangerous expansion.

Microstructure, wear, and corrosion properties of PEEK-based composite coating incorporating titania- and copper-doped mesoporous bioactive glass nanoparticles

Microstructure, wear, and corrosion properties of PEEK-based composite coating incorporating titania- and copper-doped mesoporous bioactive glass nanoparticles

Khalil Ahmad, Ayman Imran, Badar Minhas, Aqsa Aizaz, Abdul Khaliq, Abdul Wadood, Muhammad Haseeb Nawaz, Muhammad Tajammal Chughtai, Rahila Batul, Muhammad Atiq Ur Rehman

A metal implant can be strong enough to carry a load and still slowly break down inside the body. This study adds a layered protective skin that makes the surface harder to wear away and harder for body fluid to attack.

Optimization of PVDF-TrFE Based Electro-Conductive Nanofibers: Morphology and In Vitro Response

William Serrano Garcia, Iriczalli Cruz‐Maya, Anamaris Melendez-Zambrana, Idalia Ramos-Colon, Nicholas J. Pinto, Sylvia Thomas, Vincenzo Guarino

A material can carry electrical charge well and still be a poor choice for living cells. This study found that the most promising fibers were not simply the ones that conducted best.
