This is misleading. Xiaomi Regular (¥4,299)/Pro (¥5,299)/Ultra (price not out, rumored to be ¥6,499) phones are way cheaper than their respective Huawei phones (Regular: ¥5,499, Pro: ¥6,499, Pro+: ¥8,499). Also, the Mate 70 series was delayed by almost 3 months compared to the Mate 60 series. In terms of brand comparison, if we're talking about sales, either Vivo or Huawei was number 1 in China in 2024, depending on whether you count Hi Enjoy as part of Huawei. Xiaomi fell out of the top 5 for the first time in many years. If we're talking about perception, Xiaomi is pretty much considered to be the lowest end of the 6 major phone companies, way behind Huawei, Apple, and even Honor.

Chinese scientists achieve new breakthrough in "dual-loop" brain-computer "mutual learning"
on February 17 that according to Xinhua News Agency, Tianjin University and Tsinghua University jointly developed a "dual-loop" brain-computer interface system. This system is not only more accurate and energy-efficient, but can also handle more complex tasks.
This non-invasive evolutionary brain-computer interface system based on memristor neuromorphic devices successfully revealed the synergistic enhancement effect of EEG development and decoder evolution in the process of brain-computer interaction, and realized the efficient four-degree-of-freedom control of drones by the human brain. On February 17, this achievement was published in the latest issue of Nature Electronics.
you are probably 5-7 years behind time..
China's phone activations in 2024
Vivo, Huawei, Xiaomi, Apple, Honor & Oppo
1. Apple dropped from 2nd in 2023 to 4th in 2024
2. Huawei climbed from 6th to 2nd
3. Xiaomi from 5th to 3rd
in fact, Apple had disastrous Q4,2024 in mainland. they are struggling, even 2025 Week 1 show more Apple drop vs 2024 while Huawei & Xiaomi climbing and this is Alarming trend for Apple.
Xiaomi has been massively improved its brand image in past 2-3 years. sales numbers don't lie. from House appliance to other electronics gadget to Cars recently.
For the first time, total sales of the Xiaomi SU7 have surpassed Tesla's Model 3 in China since deliveries began in April 2024.
Sales in China (Apr 2024 - Jan 2025):
• Tesla Model 3: 152,748
• Xiaomi SU7: 162,384
How on earth Xiaomi beating out Tesla and Apple ?? that's because Xiaomi become the household name in middle class Chinese people and enjoying good reputation. without good brand image you just cannot beat Tesla and Apple..
You are mixing the notions of sales and brand perception. With respect to sales, I was referring to Canalys, which showed Xiaomi dropping from 5th in 2023 to others in 2024. I agree that different research firms have different methodologies. In any case, the January boost in sales for Xiaomi has to do with the subsidies in place for phones below ¥6,000 RMB, which benefits Xiaomi the most due to it's presence in this segment. And Apple sales dropping has to do with Huawei, not Xiaomi. It's no coincidence that Apple had it's best sales in China when Huawei was crushed by sanctions.
Returning to the discussion on brand value, Xiaomi's attempt at breaking into the high-end smartphone market has simply not been successful. For foldables, they had to cancel the Mix Fold 5 due to poor sales for the Mix Fold 4. No other domestic brand has had to do this, and Apple will enter the market next year. For their Ultra line, they have encountered many issues from melting wifi on the Mi 11 Ultra, to marketing the glass back as "Longjing Ceramic" on the Xiaomi 14 Ultra and downgrading the ultrawide and main cameras on the upcoming Xiaomi 15 Ultra. Also, Huawei, Apple, and Honor (only foldables for Honor) hold their value much better on the secondhand market compared to Xiaomi.
I'm not trying to diss Xiaomi. On the contrary, I use many Xiaomi products including the Xiaomi 14 Ultra as my daily driver for a long period. HyperOS 2.0 was a massive upgrade, and many aspects of its photography experience are at the very top. Xiaomi has also done the most out of any company to bring affordable smaprtphones to the masses, which is very commendable. Mijia appliances dominate the Chinese market, and since we brought up EVs, Xiaomi EVs are set to take the global market and compete with brands like BYD, Tesla, etc. I do think the SU7 Ultra will be successful, and that should lead to an overall increase in brand perception. Xiaomi has been designing its own OS, SoC (to debut in the Xiaomi 15S Pro this April), and other auxiliary chips. It also has unique benefits due to its ecosystem and global name recognition. Recently, they also poached a big name from DeepSeek to lead their AI team. Xiaomi has a lot of potential, much more than Oppo and Vivo in my opinion. Hopefully they actualize it.

Chinese scientists from CAS and PKU have made platinum-based catalyst in hydrogen production to last over 1000 hours at the same time keep the performance unaffected. They are able to protect the catalyst interface with a precise nano coating of rare earth elements oxide.
This is going to dramatically cut cost in hydrogen production.
氢能是未来能源体系的重要组成部分，如何实现高效稳定、低成本制氢是能源科技的关键课题。记者17日从中国科学院大学获悉，来自该校和北京大学的联合科研团队成功研发出一种超长寿命、高效制氢新技术。该技术通过在铂基催化剂表面覆盖特殊保护层，使催化剂在制氢反应中能够连续工作超1000小时。这一突破让低成本大规模制氢成为可能。相关研究成果在线发表于《自然》杂志。
现代化学工业中，催化技术承载着八成以上化工品生产，堪称产业命脉。在催化研究中，高活性与高稳定性，仿佛鱼与熊掌难以兼得。许多高活性催化剂虽能大幅提升反应效率，却常因结构崩塌和活性成分流失而快速失活。“比如，在甲醇-水重整制氢研究中，如何在保持催化剂高活性的同时显著提升其稳定性，已成为该领域亟待突破的关键科学难题。”论文共同通讯作者、中国科学院大学教授周武说。
在这项研究中，科研人员为破解催化剂稳定性瓶颈，开发了一种新技术：通过在铂基催化剂表面构建稀土氧化物纳米覆盖层，形成纳米级“保护盾”。这种结构可选择性覆盖载体表面的冗余位点，实现对关键催化剂界面的精准保护。实验数据显示，在甲醇-水重整制氢反应中，该新型催化剂成功稳定工作超过1000小时。更令人惊叹的是，该催化剂的活性超高，实现了超过1500万的催化转化数。
周武表示，这项研究突破了催化科学中的稳定性瓶颈，首次在不降低催化剂活性的前提下，实现了高稳定性的界面催化剂设计，为贵金属催化剂的低成本、高稳定性应用提供了可行方案，预计未来将在绿色能源、氢燃料电池等领域发挥重要作用。

Canalys is crap. Why would you trust in that?
this is smart phone activation out of China in 2024. Xiaomi was 3rd, right behind Huawei.
Whether Xiaomi is 3rd or 5th, the point still stands. Xiaomi sold more that Huawei in 2023, but less than Huawei in 2024. If we're really nitpicking, the chart you linked does not include Hi Enjoy as part of Huawei, which would push Huawei up further. So no, Xiaomi is not "catching up" to Huawei in sales. And this year Huawei will widen this gap as the effects of sanctions continue to decrease. If we are talking about brand perception, I already explained why Xiaomi is far off Huawei, Apple, and Honor. If you want more evidence, here is a list of last year's sales for phones above ¥7,000-¥8,000 RMB.
Notice how Xiaomi's best entry is #15. Above ¥8,000, Xiaomi only sells foldables. And there it loses badly to Huawei and Honor (Huawei 48.6%, Honor 20.6%, Xiaomi 7.4%). It is very clear that Xiaomi simply does not have a noticeable presence in the high-end scene. Xiaomi can change that, and I hope it does. But right now it simply isn't there.
China discovered a nickel oxide superconductor at temperatures above 40k in atmospheric pressure. This makes nickel oxide the third such superconductor after copper and iron oxides.
据新华社报道，北京时间 2 月 18 日，由薛其坤院士领衔的南方科技大学、粤港澳大湾区量子科学中心与清华大学联合研究团队在国际学术期刊《自然》上发表了一项重大研究成果，成功发现常压下镍氧化物的高温超导电性。这一发现为解决高温超导机理的科学难题提供了新的突破口，也为我国在超导乃至量子材料领域的自主发展奠定了坚实基础。
超导现象自 1911 年被发现以来，一直是物理学界的前沿研究领域。超导材料具有零电阻的特性，电流通过时完全无损耗，被广泛认为具有颠覆性的技术前景。寻找能够在常压下突破 40K“麦克米兰极限”的更高温度超导材料，一直是国际科学界的重要研究方向。
在过去三年中，薛其坤院士与陈卓昱副教授率领的研究团队持续攻关，自主研发了“强氧化原子逐层外延”技术。该技术能够在氧化能力比传统方法强上万倍的条件下，依然实现原子层的逐层生长，并精确控制化学配比。这种技术被形象地比喻为在纳米尺度上“搭原子积木”，能够构建出结构复杂、热力学亚稳且晶体质量趋于完美的氧化物薄膜，这是氧化物薄膜外延生长技术的一次重大跨越，不仅为包括宽禁带半导体等各类氧化物的缺氧难题提供了解决方案，还极大地拓展了高温超导等强关联电子系统的人工设计与制备。
此次研究中，团队成功实现了镍氧化物材料在常压环境下的高温超导电性，使镍基材料成为继铜基和铁基之后，第三类在常压下突破 40K“麦克米兰极限”的高温超导材料体系。
镍基超导研究是当前国际科学界的前沿热点，全球竞争异常激烈。值得注意的是，美国斯坦福大学的研究团队也几乎同时报告了类似材料体系中的常压超导电性。中美团队的研究路径独立，实验结果相互印证。
特别值得一提的是，中国团队全部采用国产仪器，发展了独特的强氧化能力薄膜生长技术，成功获得了晶体质量更高的薄膜材料，不仅实现了科学上的突破性发现，更为我国在超导乃至量子材料领域的长期自主发展奠定了坚实基础。

Not an expert but the material seems to exhibit strain induced 2D superconducting effects, a bit more similar to his topological insulator research.
