DURABILITY OF NATURAL POZZOLAN-BASED MORTAR EXPOSED TO SULFATE ATTACK
Cement is a strategic commodity in the civil engineering for the construction of reinforced concrete structures. But its production generates around 5% of toxic gases such as CO2 responsible for environmental degradation.

A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

Electrodeposition in Structural Lattices of Variable Architectures
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Natural durability of wood for fifteen Eucalyptus and two Corymbia species in contact with the soil
Wood can be highly susceptible to deterioration by xylophagous agents, which compromises its structural integrity and limits its use in applications involving soil contact.

Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

The main concern of using natural fibres as reinforcement in geopolymer composites is the durability of the fibres. Geopolymers are alkaline in nature because of the alkaline solution that is required for activating the geopolymer reaction.

Durability evaluation of natural-durable wood species by a fungus cellar test
ファンガスセラー試験は,保存処理木材の耐朽性の評価方法として日本の公的規格にも採用されるなど,野外試験に比較して実用的な結果が短時間で得られる手法とされている。本研究では,通常のファンガスセラー試験において,目視による評価,質量減少率の定期的かつ継続的測定を行うことにより,高耐朽性樹種のより詳細な耐朽性の評価を試みた。試験の結果,高耐朽性樹種は比較的高い耐朽性を示したが,イペ,ブラウナが高い耐朽性を示したのに対し,キャブレーバ,ジャラは低い耐朽性を示すなど,その耐朽性には樹種間で相違が見られた。ヒノキ心材にはスギ心材と同程度の耐朽性を示すものもあり,耐朽性が求められる構造材料として使用する場合には,保存処理等の配慮が必要であることが示唆された。本報告のファンガスセラー試験は ...

ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.
