Dual-passivated stainless steel could slash green hydrogen costs

Researchers at the University of Hong Kong developed SS-H2, a manganese-enhanced stainless steel that forms a second protective layer atop the chromium oxide, enabling corrosion resistance up to 1700 mV in chloride-rich environments. This makes seawater electrolysis for green hydrogen more feasible and could replace expensive titanium components, potentially cutting structural-material costs by about 40x for PEM electrolyzers. The team is moving toward industrial-scale production and has filed patents, though practical deployment in components like meshes and foams remains to be solved.

NIST Finds Surfside Collapse Traced to Weeks of Distress Before Fall

A final NIST report says the Surfside Champlain Towers South collapse began weeks before it fell, when two garage-to-pool-deck connections started failing around early June. The building’s design did not meet code, later alterations and long‑term corrosion further reduced margins against failure, contributing to a slow, deadly collapse that killed 98 people and spurred settlements and Florida maintenance-law changes for condo associations.

ESA Responds to NASA on Gateway Module Corrosion

ESA has clarified the status of the HALO and I-HAB modules delivered for NASA's Gateway, confirming HALO arrived at Northrop Grumman with corrosion signs and that I-HAB has a similar issue but has not yet shipped. An ESA spokesperson said the corrosion likely stems from forging, surface treatment, and material properties and is technically manageable, not a showstopper. ESA also noted other Gateway components, such as the life-support system and thermal control pump, are experiencing delays, and while NASA is exploring repurposing Gateway elements for a future surface base, the schedule impact remains unresolved.

Underground Fukushima Microbes Survive in Biofilm Shields, Challenging Decommissioning

Researchers studying water beneath Fukushima’s reactors found bacteria thriving in radioactive conditions not thanks to classic radiation resistance but likely because protective biofilms form on metal surfaces; some microbes can cause metal corrosion, complicating cleanup efforts, and scientists speculate marine bacteria may have ridden in with the 2011 tsunami, revealing unexpected life in extreme environments.

"Identifying the Causes of Pitting Corrosion in 3D-Printed Stainless Steel"

Researchers at Lawrence Livermore National Laboratory have identified tiny particles called "slags" as the culprits behind pitting corrosion in 3D-printed stainless steel 316L in seawater. These slags, produced during the 3D printing process, remain at the metal's surface and initiate pitting corrosion, allowing chloride-rich water to penetrate the steel and cause damage. By understanding the mechanisms behind this corrosion, the study paves the way for developing improved materials and manufacturing techniques to create stainless steel components that are highly resistant to the corrosive forces of seawater, with implications extending beyond marine applications.

Unveiling the Secrets of Atomic-Level Corrosion

Researchers are using environmental transmission electron microscopy (TEM) to study the atomic-level reactions between water vapor and metal surfaces, specifically focusing on the formation of passivation layers that protect against corrosion. By introducing water vapor to clean aluminum samples, they observed the development of an amorphous layer underneath the aluminum hydroxide layer, indicating a transport mechanism that diffuses oxygen into the substrate. Understanding these atomic reactions could lead to better corrosion management techniques and clean-energy solutions, as well as significant economic benefits.

MBTA Station Safety Concerns Raised After Woman Struck by Falling Equipment

A corroded utility box that was part of a now-defunct biological agent detection system fell and hit a woman at the Harvard Square Red Line station in Cambridge, Massachusetts. The box's supporting brace, which weighed about 200 pounds, struck the woman, causing minor injuries. The MBTA has ordered inspections of support straps at all Red Line stations and the removal of 13 remaining utility boxes at Harvard, Porter, and Davis stations. The T called the incident an "isolated case" and vowed to have all inspections completed by the end of Tuesday.
