Multiscale Structuring of Hydroxyapatite via Two‐Photon Lithography of Nanocomposites
Hydroxyapatite scaffolds are of great interest in bone tissue engineering applications, ranging from 3D cell culture to regenerative medicine. Using two‐photon lithography of a transparent nanocomposite, hydroxyapatite microstructures with features ranging from submicron to centimeter‐scale are fabricated. This allows to mimic the natural bone geometry,

External Vibrations on Early‐Age Concrete: A Review
Scientific illustration of external vibration, their influencing properties and effects, possible outcomes and measures adapted. ABSTRACT Early‐age concrete exhibits limited mechanical strength, making it highly susceptible to external disturbances such as vibrations from construction activities, traffic, or nearby machinery which can disrupt internal ...

MnO2‐coated OPEFB fibers produced via a simple wet process showed smoother surfaces and significantly reduced water absorption in fiber cement composites, enhancing moisture resistance. ABSTRACT The use of natural fibers in cement‐based composites is increasingly encouraged as a sustainable alternative to synthetic fibers; however, their inherent ...

Anchorage System Contribution to Post‐Tensioned Bridge Collapse
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior
This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

In Situ Detection of Opal‐A in Jezero Crater, Mars
Abstract We report the in situ detection of amorphous hydrated silica in the Bills Bay abrasion patch, located in the eastern portion of the Margin Unit between the rim of Jezero crater and the western delta. Here, hydrated silica co‐occurs with olivine, Fe‐Mg carbonates, secondary Fe‐Mg silicates, and hydrated Mg‐sulfate as determined by UV Raman ...
