China leads the world in four out of 11 frontier areas of academic research, with major improvements to clinical medicine, astronomy and astrophysics in the past five years, according to the annual report released on Tuesday by the Institutes of Science and Development of the Chinese Academy of Sciences and global analytics firm, Clarivate.

The report titled Research Fronts 2022 identified 110 "especially active" and 55 emerging research fronts that are categorized into 11 broad scientific areas based on data from highly cited papers published from 2016 to 2021.

On the Research Leadership Index, the United States scored the highest in seven out of the 11 broad categories this year, namely geosciences, clinical medicine, biological sciences, astronomy and astrophysics, mathematics, information science and economics, and psychology and other social sciences.

China topped the remaining four frontier scientific areas — agricultural, plant and animal sciences, ecological and environmental sciences, chemistry and materials science, and physics.

China's global rankings in clinical medicine and astronomy and astrophysics have seen major improvement over the past five years, the report said. Its rank in clinical medicine climbed from 13th on the index in 2018 to 4th this year, while it ranked 7th in astronomy and astrophysics against 19th five years ago.

Among the 165 research fronts, the U.S. is most active in 79 and China in 52. The two countries together led nearly 80 percent of all research fronts.

Chemistry and materials science has emerged as China's most prolific and advantageous field, with the country leading in 10 out of the 13 research topics in this category. Ecological and environmental sciences came in second, with China topping eight out of 12 topics.

Gao Hongjun, vice-president of the CAS, said that China would expand openness and cooperation in science and technology, and find new solutions to global challenges with the international scientific community.

Pan Jiaofeng, president of the Institutes of Science and Development, CAS, said that researchers had identified eight scientific trends this year based on further analysis of the report.

The key trends are using artificial intelligence to aid studies; COVID-19 as a strong driver for research; breakthroughs in geosciences are the main pillars for supporting energy security in the foreseeable future; and solving food security and public health issues requires major open scientific projects in gene technologies.

"At present, different scientific disciplines are crossing paths, with breakthroughs in basic sciences — from materials science to life sciences," Pan said. "We need more objective and continuous evaluation of quality scientific research, so that science and technology policymakers can plan future research directions."

The team under Nanjing Tech University chemical engineering professor Zongping Shao stated that their device “ran for over 3,200 hours under practical application conditions without failure.

Currently, the majority of H2 is made using methods powered by fossil fuel, meaning that even though H2 itself doesn’t lead to CO2 emissions when used as a fuel, there are greenhouse gasses emitted from producing it.

Electrolyzing seawater has been a top goal for hydrogen production, but barriers were considerable.

Being able to electrolyze salt water into H2 to be used as a green fuel is an appealing goal, but seawater is notorious for the corrosion it causes to electrodes used in electrolyzers. As a result, electrolyzing seawater is typically seen as unviable.

While some hydrogen production researchers have applied polyanion coatings in attempts to resist the corrosion from chloride ions and some have tried highly selective electrocatalysts, but they have not been appropriate for practical application. Desalinating water requires energy, reducing the efficiency of the hydrogen production in the first place.

The team focused their seawater hydrogen production on the use of a concentrated potassium hydroxide electrolyte solution in which the electrodes were dipped. This, combined with a porous membrane helped to separate the seawater and electrolyte solution. The membrane was fluorine rich, allowing water vapor to penetrate it while blocking liquid water.

"Importantly, this configuration and mechanism promise further applications in simultaneous water-based effluent treatment and resource recovery and hydrogen generation in one step."

The researchers are positive that their device, along with producing hydrogen, will also be able to recover lithium from the seawater. Further applications of the device extend to activities like cleaning industrial freshwater.

China makes 'revolutionary' breakthrough in power plant cooling

Yanghuopan Power Station, the world's first power plant equipped with the natural direct cooling technology, connects to grid in Yulin City, northwest China's Shaanxi Province, December 30, 2022. /CMG

China achieved a breakthrough in power plant cooling technology as the world's first plant with a "natural direct cooling" (NDC) system connected to grid on Friday in Shaanxi Province.

The technology, described as "a revolution in industrial air cooling" by local newspaper Shaanxi Daily, makes use of the natural air flow in the plant to guide the heat to air condenser.

Compared to traditional air-cooling technologies, the NDC system doesn't use any fans to create air flow, saving electricity and reducing noise, according to an explainer posted by PowerChina Northwest, developer of the tech.

PowerChina Northwest said the NDC system also requires no water pumps compared to indirect cooling technologies.
"The NDC system combined the advantages of both air-cooling and indirect cooling systems," said the Shaanxi-based company.

With the system in place, the Yanghuopan Power Station in Shaanxi's Yulin City can save 24,500 tonnes of coal and reduce 54,100 tonnes of carbon emission every year, according to a report from China Media Group (CMG).

CMG also said the plant emits almost no soot, sulfur dioxide or nitrogen oxide.

The power plant has a yearly capacity of 660 gigawatt-hours and will help solve the power shortage in central China.
The NDC technology has been listed as national-level key technological equipment, according to Shaanxi Daily.

HW前HR posted this on weibo. Good summary of China's tech progress in 2022
2022中国工业上是辉煌的一年,2023年是个值得期望的一年!

2022年,在航天上,中国的空间站一期建成了,最多时6名航天员会师空间站。这一年我国使用20种型号火箭共进行了64次航天发射,破了历史记录。实际上看,在航天中美已经没有什么实质性技术上差距,美国宇航局的大火箭,中国完全可以在长五技术组装出来。而中国2022年虽然发射次数少于美国,但是美国主要靠的是马斯克的星链在发垃圾一样,真正发射各种各样卫星,中国的种类和创新已经更是领先。尤其是,中国空间站建成,说明中国在长时间人员生命体系维系方面和大型空间设备运营方面已经赶上了。
First accomplishment are the space station construction and 64 launches with 20 different types of rocket. America is only ahead due to starlink launches.
2022中国航空也是精彩的一年,歼35在2021年底横空出世后,今年试飞各种实质性进展图让人不用担心隐身舰载机。歼20双座和歼20B也各种应用和曝光,空军战机已经赶上。C919交付航空公司、ARJ21交付过百架,运20油官宣。曾经欠账较大的航空领域已经基本赶上来,虽然民用的还有不少距离,但是已经进入三分天下的起跑线了。
we already know about military aviation + C919/ARJ21
2022年汽车是惊艳一年,中国自主品牌已经占一半,11月份占领54%份额了,这是很多人想都不敢想的。在中国这个竞争最激烈市场拿下后,必然在外部攻城掠地。中国新能源车占了全球60%份额,中国动力电池占了全球2/3。中国汽车出口今年稳居全球第二,下半年已经稳居全球第一。汽车是中国长期落后的领域,没想到通过电动车要后来居上了。
auto industry has been a huge success. 54% domestic sales are now by Chinese brands (In November).
2022年是中国海上装备突飞猛进一年,福建舰下水,055全交付,9米大直径潜艇构建实锤曝光。中国进入以优制优阶段,特别yj21横空出世,人无我有,出现不可思议的不对称领先优势。中国已经有6大船厂可以造LNG船,占全球9大船厂的2/3,中国也大量交付24000箱集装箱船,还接近完成大型邮轮;中国去年占了全球商业造船的49%,很快就要过半了。
aside from military shipbuilding, 6 shipyard now capable of building LNGs (2/3 of the world's total), started delivering many 24000 TEU container ships. They are also getting close to completing mega cruise ships. Almost half of world's shipbuilding production.
当然,在发电设备上,中国第四代核电站投入商用;全球最大16MW风力发电机下线;最大的百万千瓦级水轮发电机组投入商业运营。水电站“大脑”核心控制系统首次实现全面国产化。中国在发电上已经成为全世界技术的高地。
In power generation put in 4th generation nuclear reactor, the world's largest 16MW wind turbine generator, largest hydroelectric power generator into service, hydro power stations computer/control system is finally fully domestic for the first time.

而最令人揪心的半导体设备,在当前招标中,50%国产化中标已经是常态,国产设备供不应求。权威人士说28nm国产光刻机已经在试点应用,40nm去A化生产线跑通,这些都是好消息。
In semiconductor tool bids, 50%+ of bids now go to domestic tool makers and domestic equipment cannot fill the demand. 28nm lithography machine in test usage and 40nm de-americanized line is in production.
2023年,我们将坐上国产大飞机,福建舰开始海试,而歼35和歼20B我们见看到更多精彩进展。第二批055改可能要投入了,H20,076也快和大家见面了吧?国产自主可控生产线的生产的手机处理器是不是也要出山了?经过困难而出彩的2022,我们将迎来辉煌的2023年。中国的世纪脚步声已经响起,而我们就是这群创造历史奇迹的一员。
In 2023, looking for C919 coming into service, CV-18 start sea trials, 2nd batch of 055s, J-35/J-20B development, H20/076 appearing?
maybe fully domestic production line for smartphone CPUs.
