Enabling Real‐Time, Non‐Ionizing 3D Imaging of Implantable Magnetic Cements Using Magnetic Particle Imaging

Advanced Materials Interfaces, EarlyView.
This study reports the first implantable resin cement capable of orientation‐sensitive Magnetic Particle Imaging (MPI). By coating the cement with an ultrathin iron film, the authors achieve a strong, angle‐dependent MPI signal that enables non‐ionizing, real‐time tracking of both implant position and orientation, opening new possibilities for safe ...

Sustainability of concretes with binary and ternary blended cements considering performance parameters

Cement, 2023
This paper examines the sustainability of cementitious materials and concrete. Although the environmental impact of these materials is often evaluated based on their CO2 emissions per ton of cement or m3 of concrete, incorporating performance parameters ...

Microbial Contribution to Soiling and Its Impact on Photovoltaic Module Soiling in Arid Zones of the Atacama Desert

Advanced Sustainable Systems, EarlyView.
Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.

Designing Reinforced Concrete Beams Containing Supplementary Cementitious Materials. [PDF]

Materials (Basel), 2019
If supplementary cementitious materials (SCMs) are used as binders, the environmental impact produced by cement-based composites can be reduced. Following the substitution strategy to increase sustainability, several studies have been carried out with the aim of measuring the mechanical properties of different concrete systems, in which a portion of ...

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Recycled powder as filler admixture in cementitious systems : production and characterization [PDF]

, 2016
In concrete production, aggregate represents almost 75% of the materials used. The exploitation of natural sources for this purpose also causes an environmental impact, while deposition of wastes from construction industry pollutes soil and water.

Astrocytic PCBP1 Suppresses Ferroptosis to Restore Glutamatergic Homeostasis and Mitigate Stress‐Induced Depression in Male Mice

Advanced Science, EarlyView.
This study demonstrates that polyC‐RNA‐binding protein 1 (PCBP1) in ventral hippocampal astrocytes modulates depressive‐like behaviors by regulating glutathione peroxidase 4‐mediated ferroptosis and synaptic glutamatergic transmission. PCBP1 overexpression intervention in the chronic unpredictable mild stress model rescues behavioral deficits ...
