Tobacco waste ash: a promising supplementary cementitious material [PDF]

International Journal of Energy and Environmental Engineering, 2018
Según la Asociación Europea del Cemento, CEMBUREAU, en 2015, la producción mundial de cemento fue de 4.600 millones de toneladas. La producción tradicional de cemento emite aproximadamente 1 tonelada de CO2 por tonelada de cemento, lo que representa casi el 80% de las emisiones totales de CO2 del hormigón y aproximadamente el 6% de las emisiones ...

Quantum Photothermal Self‐Monitoring Fiber Probes for In Vivo Photothermal Therapy

Advanced Science, EarlyView.
A miniaturized quantum photothermal fiber probe based on a metal/polymer/glass composite optoelectronic fiber that simultaneously guides lightwave and microwave was developed for the first time. The probe achieves enhanced photothermal conversion (13°C/mW, 25°C–120°C range) while providing real‐time self‐monitoring with 0.2°C thermal resolution at the ...

The E3 Ligase RNF115 Aggravates Pathological Cardiac Hypertrophy via Ubiquitin‐Mediated Degradation of SPTBN1

Advanced Science, EarlyView.
In response to hypertrophic stimuli, increased c‑JUN phosphorylation upregulates RNF115, leading to SPTBN1 ubiquitination and degradation. which promotes F‑actin depolymerization and YAP activation, driving cardiac hypertrophy. The RNF115 inhibitor DTD effectively suppresses SPTBN1 ubiquitination and cardiac hypertrophy.

Mechanical properties and microstructure of low carbon high-strength engineered cementitious composites with supplementary cementitious material

Case Studies in Construction Materials
The carbon emissions associated with concrete production remain a significant unresolved issue. One effective approach to mitigate this problem is to partially substitute cement with supplementary cementitious materials.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

Advanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.

Waste ceramic powder for sustainable concrete production as supplementary cementitious material

Frontiers in Materials
A detailed examination was carried out by substituting waste ceramic powder (WCP) for specific ratios of cement in concrete. To achieve this, five different WCP percentages (10%, 20%, 30%, 40%, and 50%) were used in manufacturing of concrete.

Reduction of Radon Gas in Concrete Using Admixtures and Additives

Nordic Concrete Research, 2018
The second largest cause of lung cancer is related to radon (222Rn) and its progenies in our environment. Building materials, such as concrete, contribute to the production of radon gas through the natural decay of 238U from its constituents. The Swedish
