Microscopy reveals how atom-high steps impede oxidation of metal surfaces

Microscopy reveals how atom-high steps impede oxidation of metal surfaces

Low-energy electron microscopy images of the nickel-aluminum surface before and after oxidation. The faint lines before oxidation indicate the atom-high steps that separate flat terrace sections of the crystal surface. As oxidation begins at a point on one terrace, the oxide spreads in elongated stripes along that terrace, pushing steps out of the way and bunching them closer and closer together. Eventually the bunching of steps stops the growth of the oxide stripe and another begins to form, often at right angles, to produce a grid-like pattern. Credit: Brookhaven National Laboratory

Rust never sleeps. Whether a reference to the 1979 Neil Young album or a product designed to protect metal surfaces, the phrase invokes the idea that corrosion from oxidation—the more general chemical name for rust and other reactions of metal with oxygen—is an inevitable, persistent process. But a new study performed at the Center for Functional Nanomaterials (CFN) at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory reveals that certain features of metal surfaces can stop the process of oxidation in its tracks.

Millions of damage after New Caledonia nickel spill

Initial assessments from last week’s nickel spill at New Caledonia’s Koniambo plant put the damage at more than three million US dollars.

The incident on the day after Christmas prompted the evacuation of all staff from the seven-billion US dollar plant in the territory’s north and led to a temporary stop to production.

There are no reports of any injuries.

About 500 tonnes of liquid nickel was spilled from one of the furnaces for reasons yet to be determined.

POSCO builds lithium extracting plant in Argentina

POSCO Co., South Korea’s largest steelmaker, said Monday that it has completed the construction of a lithium plant in Argentina that will mass produce the material needed to make batteries for electronic devices.

The plant located in Jujuy, in the northern part of Argentina, can produce up to 200 tons of lithium every year by directly extracting the material from water from a nearby lake through chemical reactions, a technique that requires less time than traditional means of production.

India looks to sway Americans with nuclear power insurance plan

NEW DELHI: India is offering to set up an insurance pool to indemnify global nuclear suppliers against liability in the case of a nuclear accident, in a bid to unblock billions of dollars in trade held up by concerns over exposure to risk.

Prime Minister Narendra Modi’s government is hoping the plan will be enough to convince major U.S. companies such as General Electric to enter the Indian market ahead of President Barack Obama’s visit at the end of next month.

Indonesia Project Sukuk Plan Sees Fivefold Rise: Islamic Finance

Indonesia is ramping up financing for new President Joko Widodo’s $439 billion development program, planning an almost fivefold increase in sales of project sukuk.

The government is seeking to raise 7.14 trillion rupiah ($568 million) from notes that will fund particular construction ventures next year, compared with 1.5 trillion rupiah this year, Suminto, Islamic financing director at the debt management office, said in a Dec. 12 interview in Jakarta. That will help finance its estimated spending of about 5,519 trillion rupiah from 2015 to 2019 to build roads, railways and power plants.

Aerojet Rocketdyne successfully tests 3D-printed propulsion system

Aerojet Rocketdyne has completed the hot-fire test of its 3D-printed MPS-120 CubeSat high-impulse adaptable modular propulsion system.

Carried out in Redmond, Washington, MPS-120 testing showed the required throughput on the engine for more than five times and several expulsions on the propellant tank, according to Aerojet.

Said to be the company’s first 3D-printed hydrazine integrated propulsion system, the MPS-120 features four miniature rocket engines, feed system components, a 3D-printed titanium piston, and propellant and pressurant tanks.
