Hong Kong has approved around 1,400 applications for visas under a scheme that aims to attract talent, the city’s labor chief said Wednesday, as the financial hub attempts to revive its strained job market and boost economic recovery.
The Top Talent Pass Scheme has had an enthusiastic response, with around 2,600 applicants within a week of its launch last Wednesday, Chris Sun, Hong Kong’s Secretary for Labour and Welfare, said at a press briefing.
Under the program, individuals who had an income of at least HK$2.5 million ($320,127) in the past year, or graduates of the world’s top 100 universities that have at least three years of work experience over the past five years can apply for a two-year visa.
Graduates from these universities in the past five years with less than three years of work experience can also apply but are subject to an annual quota. Applicants do not need to be employed or have a job lined up to be approved.
The first batch of approvals were made within a few days, while some applications got the go-ahead on the same day they were submitted, Sun said. The minister is currently on a seven-day trip to Singapore and the Philippines to gather overseas experience on talent recruitment.
Luo Yi, a recent graduate from University College London, told Caixin he submitted his application when the scheme went live last Wednesday and received an approval the same day.
Hong Kong is trying to kick-start its economy and restore its image as a financial and business hub, which has been tarnished by strict Covid policies and an exodus of talent. In September, the city lost its top spot in Asia to Singapore on the Global Financial Centres Index, which ranks the competitiveness of the world’s major business hubs.
The Top Talent Pass Scheme is part of a package of unveiled by Chief Executive John Lee in his maiden policy address in October. The city’s workforce has shrunk by about 140,000 over the past two years, Lee said in his address.
The government aims to admit at least 35,000 talented individuals annually with an intended duration of stay of at least 12 months through talent admission schemes from 2023 to 2025, an increase of 40% over the average number in 2020 and 2021, according to the policy address.
Interesting comments I gotta say, especially if the people are what they claim to be.
Posts like this absolutely annoys me. We created a quantum computing thread just very recently so that all the quantum posts can go there and I had to already move posts there once already.
Please do some relevant searches on this forum and post your content on the correct thread in the future!
With how important A.I is and how complicated the topic is, A.I ethics, censorship issues, the dangers of A.I , should there be a thread just for A.I news?
perovskites are not generally organic metal halides. perovskite refers to a form of (ideally) cubic crystal lattice only with an ABX3 formulation. the most common perovskites are oxides, particularly titanates. the original perovskite was CaTiO3. prior to PV research, the better known use of perovskites was in piezoelectric materials like PZT (lead zirconium titanate).
even in PV applicable pervoskites, there was research into a stable purely inorganic perovskite CsPbI3. thus, I thought it necessary to specifct the exact perovskite type that I was talking about, to avoid ambiguity and confusion.
In addition, the degradation due to water indeed occurs within the perovskite itself, at least for methylammonium PbI3. It is observed degrading into methylammonium iodide and PbI2 in the presence of water, see literature (figure 4):
Also additional simplified literature:
hole transport material is indeed a weak point due to the ease of oxidation for organic semiconductors, but that is entirely separate from the water based degradation of the perovskite layer. I am not familiar with HTL issues, so I'll defer to your expertise.
You've confused a lot of things. The examples you've given are things that I've briefly clarified in my earlier post. The cesium lead example is classic bivalent metal cations within the perovskite structure. As for the years old papers you suggested talks about hygroscopy in case of particular organic scenario or single layer perovskite which are failed approach.
You can clarify a lot of your confusion by reading this paper from last year by Professor Tan Hairen about tandem perovskite, particularly the optimization of functional layers part.
I am not a SME, so I defer to your expertise. However, I do have some questions. From a simple reading of your source, it doesn't seem to mention the water mediated decomposition of the perovskite. It only refers to passivation of electronic defects with additives, and hygroscopicity of the HTL. Can you point out where the source says the perovskite decomposition problem is solved, and by what mechanism?
In addition, another recent paper (2022) noted the continuing water instability of the perovskite layer and proposes strategies to mitigate it. I don't think mitigation strategies would be necessary if in fact this was a solved problem.
Huawei signed OpenHarmony Ecosystem agreement with 24 partners
Published 4 hours ago on January 10, 2023 By Emiko Matsui
The open-source HarmonyOS, OpenHarmony is expanding its partners across the industry, and Huawei is helping the OpenHarmony manager, OpenAtom to further establish its roots in the ground. As recently, Huawei signed an agreement with 24 industry partners of OpenHarmony Ecosystem Enablement Cooperation.
This agreement will cover industries such as finance, education, transportation, energy, government affairs, manufacturing, health, radio and television, and telecommunications to jointly promote the OpenHarmony ecosystem and its development across the community.
OpenHarmony is an open-source project donated to China’s OpenAtom foundation. OpenAtom Foundation is also collaborating with Eclipse Foundation to collaborate on OpenHarmony.
Huawei is working with various partners to jointly develop new OpenHarmony capabilities, and the ecosystem will accelerate with various industries. There are already 102 commercial devices and 94 models. In terms of counts, the development board modules and 28 software distributions have passed community compatibility assessments.

Related to this matter, Huawei has set up OpenHarmony Enablement Department to provide services to over 20 enabling services including industry insights, training empowerment, and technical support.
Last year was quite successful for this open-source HarmonyOS. As OpenHarmony opened the gates for 6 ecosystem partners. It’s reflecting that Huawei is collecting new partners to explore opportunities in the development OpenHarmony and the latest cooperation with 24 partners is the latest achievement in this way.
Below you can check all of the 25 partners joining hands with Huawei.
