Synergic effect of waste brick powder, waste ceramic powder and marble powder on rheological behaviour, mechanical behaviour and carbon footprint of binary and ternary mortars

Although waste brick powder (WBP), waste ceramic powder (WCP), and marble powder (MP) have been individually investigated as cement substitutes, their combined effects on rheological behaviour, mechanical performance, and strength-normalised environmental efficiency remain insuff...

Three-colour pride—geometry and topological transformations in self-assembly models of three-arm star molecules

Abstract Polyphilic three-arm star-shaped molecules self-assemble in a wide variety of morphologies. We present an analysis of the geometry of the possible mesophases formed by three-star molecules with mutually immiscible arms. The structures resulting from such molecular self-a...

Experimental Investigation of Thermal and Mechanical Properties of Sorghum Stalk Fiber-Reinforced Cement Mortar for Thermal Insulation: Influence of Length, Percentage of Fibers and Water to Cement Ratio

Sustainable building materials development is essential for improving energy efficiency, addressing environmental concerns and optimizing resources use. This study investigates the development and characterization of sorghum stalk fiber-reinforced cement mortar bio-composite for...

Altered excitation-inhibition balance in the somatomotor and default mode network in multiple sclerosis

Excitation-Inhibition (E/I) balance is a system-level principle governing healthy neuronal information processing. Its disruption has been implicated in the pathophysiology of multiple sclerosis (MS), yet in vivo characterization of E/I balance in MS remains under debate. In MS,...

Chemical desorption of methanol induced by hydrogen abstraction–addition cycles on cold grain surfaces

Abstract We report ultra-high vacuum experiments on the non-thermal desorption of methanol (CH3OH) from cold dust-grain analogues under hydrogen-atom bombardment. Monolayer methanol films on polycrystalline gold, compact amorphous solid water (ASW, 10 ML) and 13CO ice (2 ML) are...
