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 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.

Singapore (Platts)–17Dec2014/345 am EST/845 GMT

China plans to scrap import taxes on ferronickel and ferrochrome containing more than 4% carbon, starting January 1, 2015, according to a notice dated December 12, on the Chinese finance ministry website. Import tax on both products are currently at 1%. Market observers expect China’s import of ferronickel to increase with the scrapping of the import tax.

Schematic of the preparation of a 3-D hierarchically structured graphene-sulfur/carbonZIF8-D composite

What do you get when you wrap a thin sheet of the “wonder material” graphene around a novel multifunctional sulfur electrode that combines an energy storage unit and electron/ion transfer networks? An extremely promising electrode structure design for rechargeable lithium-sulfur batteries.

The demand for additive manufacturing (or 3D printing, depending on your preference) using metal powders is growing rapidly. Consider that last year the number of metal-based production systems sold increased 75.8 per cent, according to May’s Wohlers Report. And the quality of what’s being made from machines, though there’s room for improvement, is going up rapidly.

Don’t expect U.S. coin compositions to change any time soon, and never for the penny. There are “no alternative metal compositions that reduce the manufacturing unit cost of the penny below its face value,” according to the United States Mint 2014 Biennial Report to Congress on the research and development (R&D) of alternative metals for circulating coins.

Absorbing material can be used in airplane coating for reducing radar reflection and reducing radar signature, to improve mission success rate,   survival probability of warplanes and stealth operations in enemy range. Therefore, it will be of great significance in developing new type absorbing materials.

According to loss mechanism, microwave absorption can be divided into resistor type, dielectric type and magnetic medium type. Based on resonance and magnetic hysteresis loss principle, magnetic medium absorber can be used in reducing electromagnetic wave, in which the representative materials mainly include ferrite and micro metal powder. Micro metal powder mainly includes carbonyl iron powder, carbonyl nickel powder, permalloy, cobalt nickel alloy and so on.
