Recent Developments in Energy Storage and Conversion Applications of Multifunctional Vanadium Carbides

open access: yesAdvanced Materials Technologies, EarlyView.
This review systematically explains the synthesis, properties, and energy storage and conversion applications of vanadium carbides. We introduce the structural and the synthetic strategies and reviewed recent developments in the material synthesis processes. The emerging applications of vanadium carbides in energy storage and conversion are highlighted.

Bridging Boltzmann and Non‐Boltzmann Optical Thermometry Enabled by Multimodal Perovskite Nanocrystals

open access: yesAdvanced Optical Materials, EarlyView.
Multimodal perovskite nanocrystals enable optical thermometry across multiple excitation and emission regimes, spanning the UV–Vis–NIR spectral range. By combining upconversion, downshifting, and persistent luminescence, the platform bridges conventional Boltzmann and non‐Boltzmann thermometric approaches.

A new mortar from a strange ancient mortar

open access: yes, 2019
During the restoration of Perseus, a sculptural complex realized by G. B. Pieratti in the XVII century sited in Boboli Garden (Florence), an ancient mortar used as glue of iron pivots with very particular characteristics was found. Indeed this mortar was made of a magnesium hydroxide based binder (brucite) and barite (barium sulphate) as aggregate ...

Binder leaching of naturally hydraulic lime (NHL) mortars [PDF]

open access: yes, 2012
Masonry built in lime mortar is one of the principle building materials used in traditional construction. This form of construction can convey the appearance of strength and stability and could be argued to epitomise built homogeneity.

Damage Evolution In Cement Mortar Due To Erosion Of Sulphate

open access: yes, 2008
Ultrasonic technique is used to detect the velocity change of stress wave propagated in the cement mortar immersed in the solution of sodium sulfate for 425 days. Also the density change of specimens at different erosion time is measured.

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Assessing durability of geopolymer concrete mortar for sewer pipe coating

open access: yes
Alkali-activated geopolymer (GP) is emerging as a promising alternative to Ordinary Portland Cement (OPC) in addressing microbial-induced concrete corrosion (MICC) of concrete structures in aggressive sewerage environments.
