Thermal Coefficients of Paste-Paste Type Pulp Capping Cements
Dental Materials Journal, 1992 Thermal coefficients of four kinds of commercially available paste-paste type pulp capping cements were examined. Control reference samples were made of dentin. A thermal coefficient analyzer was used, heating specimens for a few nanoseconds by a xenon flash bulb and measuring thermal changes by using a thermocouple.

Advanced Science, EarlyView.A lithium‐bearing slag is investigated with the goal of holistic valorization. The present β‐eucryptite (LiAlSiO4) exhibits a high lithium content and low levels of impurities. The spinel contains most of the chromium and vanadium, representing additional valorization opportunities.

Improving the chloride binding capacity of cement paste by adding nano-Al2O3
Construction and Building Materials, 2019 The chloride binding capacity of cement paste is of critical importance to the durability of reinforced concrete structure. In this study, nano-Al2O3 (NA) was considered as an additive to be used in cement paste.

Yield stress of aerated cement paste [PDF]
Cement and Concrete Research, 2019 Yield stress of aerated cement paste is studied. Samples are prepared by mixing aqueous foam with cement paste, which allows controlling bubble size, gas volume fraction and yield stress of the cement paste.

Advanced Intelligent Systems, EarlyView.This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Effect of montmorillonite as additive on the properties of cement-based composites
Science and Engineering of Composite Materials, 2012 The aim of this study was to investigate the effect of montmorillonite as additive on the properties of cement paste and mortar. Montmorillonite was used at 0%, 5%, 10% and 15% additive by weight of cement, and the water/cement ratios of 0.45 and 0.55 ...

Journal of Applied Polymer Science, EarlyView.Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...
