Platform Thinking as a Catalyst for Circular Innovation in Low‐ and Medium‐Tech Industries
Business Strategy and the Environment, EarlyView.ABSTRACT Growing pressures to replace linear with circular models challenge organisations to innovate continuously and to absorb new knowledge. While platform thinking has been examined as an enabler of innovation in high‐tech industries, its relevance in low‐ and medium‐tech industries, like construction, remains underexplored.

New Insights Into the Three‐Dimensional Mechanics of the Flagellar Beat Cycle
Cytoskeleton, EarlyView.ABSTRACT Advances in imaging at the molecular scale have provided greater detail concerning the three‐dimensional structure of the ciliary/flagellar axoneme. Additionally, it has recently been confirmed that electrostatic forces regulate the dynein‐tubulin interaction at the microtubule binding domain (MTBD) of dynein, and at the junction of the nexin ...

Effect of Eggshell Powder on the Hydration of Cement Paste [PDF]
Materials, 2019 Eggshells are one of the solid wastes in the world and are considered hazardous according to European Commission regulations. The utilization of solid wastes, like eggshells, will help create a sustainable environment by minimizing the solid wastes that are disposed into the environment. The utilization of eggshell powder in cement also helps to reduce

Deep Underground Science and Engineering, EarlyView.Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling

Concentration effects in the rheology of cement pastes: Krieger-Dougherty revisited [PDF]
, 2011 Cement pastes are concentrated suspensions of granular particles in water and their rheology strongly affects the behaviour of all concretes and other cementitious materials.

Deep Underground Science and Engineering, EarlyView.This study investigates the damage evolution and failure mechanisms of tunnel lining concrete in active fault zones through uniaxial compression tests integrated with acoustic emission (AE) monitoring. A strong linear correlation is identified between the AE cumulative absolute energy and the total strain energy, providing a reliable energy‐based ...

EcoEnergy, EarlyView.Carbon‐negative carbon nanotubes produced by molten CO2 electrolysis offer a low‐cost, high‐performance alternative to graphite in Li‐ion battery anodes. Replacing conventional carbon materials with electrolytic CNTs can improve battery capacity and charging performance while reducing costs and contributing to carbon mitigation.
