Enhancing CO capture in cement-based materials with alkanolamines: A comprehensive study on efficiency, phase-specific impact, and carbonation mechanisms.

The escalating issue of global warming, driven by the surge in CO emissions, necessitates innovative strategies for reducing CO emissions. A novel approach is explored in this study, where amines featuring a basic N atom with a lone pair are incorporated into cement paste to facilitate CO capture from the environment. Unlike conventional applications, the focus is on the collaborative effect of various amines on CO capture within diverse calcium-rich phases, encompassing portlandite and Calcium-Silicate-Hydrate (C-S-H).

Carbon nanohorn coating by electrodeposition accelerate bone formation on titanium implant.

Direct contact between bone and implant materials is required for dental implants. Titanium is used for the implant material owing to its mechanical and biological properties. The anodisation as the surface treatment was employed to enhance osteogenesis around titanium.

3D printed solution flow type microdroplet cell for simultaneous area selective anodizing.

Introduction: Recent advancements in 3D printing technology allow us to design and fabricate customized droplets cells for localized electrochemical patterning.

Objectives: In this study, 3D printed solution-flow type microdroplet cell (Sf-MDC) is proposed for localized anodizing of two different regions on Al surface. The effect of printing orientation on 3D printing parameters is elucidated to minimize the resin consumption, printing time and material wastage.

Aluminum microstructures on anodic alumina for aluminum wiring boards.

The paper demonstrates simple methods for the fabrication of aluminum microstructures on the anodic oxide film of aluminum. The aluminum sheets were first engraved (patterned) either by laser beam or by embossing to form deep grooves on the surface. One side of the sheet was then anodized, blocking the other side by using polymer mask to form the anodic alumina.

Synthesis of aluminum oxy-hydroxide nanofibers from porous anodic alumina.

A novel method for the synthesis of aluminum oxy-hydroxide nanofibers from a porous anodic oxide film of aluminum is demonstrated. In the present method, the porous anodic alumina not only acts as a template, but also serves as the starting material for the synthesis. The porous anodic alumina film is hydrothermally treated for pore-sealing, which forms aluminum oxy-hydroxide inside the pores of the oxide film as well as on the surface of the film.
