Construction progresses on China’s High Temperature Pebble Bed Nuclear Reactor

The pouring of concrete for the basemat of the first HTR-PM unit – a demonstration high-temperature gas-cooled reactor – at Shidaowan in China’s Shandong province was recently completed. Another 19 of the small modular reactors could follow. HTR-PM are modular reactors that will be mainly factory mass produced. The first one is taking 5 years …

Hybrid nanotube-graphene material that promises to simplify manufacturing

Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handle in a new hybrid material grown by researchers at Rice University. The Rice lab of chemist James Tour set nanotubes into graphene in a way that not only mimics how steel rebar is used in concrete but also preserves and even improves …

China has mini-stimulus of about $300 billion which is about 3% of the $10 trillion economy

1. China outlined a package of measures including railway spending and tax relief to support the economy and create jobs after a slowdown endangered Premier Li Keqiang’s target of 7.5 percent growth this year. It’s a mini-stimulus package designed to stabilize growth,” said Xu Gao, chief economist with Everbright Securities Co. in Beijing. “As the …

Gene Synthesis Costs have been slower to improve than previously expected

The general approach begins with DNA from a variety of sources. Here we used oligonucleotides synthesized from microarrays as well as from conventional sources. Then, next-generation sequencing is used to read and identify oligonucleotides Back in 2007, George Church and others had predicted rapid improvement for the cost of gene synthesis. Right now the cost …

Metamaterials can improve magnetic resonance imaging

Arxiv – Active split-ring metamaterial slabs for magnetic resonance imaging. (6 pages) Researchers have created a switchable metamaterial that becomes invisible when not needed. It has been built and tested and it improves the signal to noise ratio of the resulting images by 15%. The MRI improvement will be improved further by optimising the design. …
