疫情後美國入境健康準備與史丹佛入學健康準備

 目前入境美國除了COVID-19兩劑接種證明之外，也需要出示航班出發前一日內進行採檢的COVID-19陰性檢測報告(英文報告)

參考資料: 長榮航空最新旅遊限制相關規定

\注意這邊的COVID-19陰性檢測報告用快篩結果即可，然後出發前一日的定義是航班出發前一天即可，不用嚴格24小時內，比如是5/2 23:00出發的航班，那5/1早上去做的快篩報告也算數。

以下連結為網友整理得台灣有做抗原快篩的醫院整診一覽表。

史丹佛入學前除了需要有COVID-19兩劑接種英文證明之外，也需要施打麻疹(measles)、腮腺炎(mumps)及德國麻疹(rubella (German measles))三種疫苗 (MMR，兩劑接種證明)，一般1992年出生的同學應該出生時應該都有接種過一劑MMR三合一疫苗，第二劑應該是國小時候施打的，所以只要去醫院或衛生所補開英文疫苗紀錄即可。

拿到COVID-19和MMR兩劑接種證明後，就可將資料登入學生疫苗紀錄系統。學生疫苗紀錄分為線上及紙本兩部分。

線上的部分只需要將之前疫苗施打的紀錄填入史丹佛的線上表格即可(https://vadenpatient.stanford.edu/，J1身分需要startday當日才會開通)。

紙本的部分需要醫師證明，所以需要各位同學帶著史丹佛校方的表格(連下如下)去找家庭醫學科或旅遊醫學科的醫師幫忙填寫及證明

Bifunctional TiN@N-doped-graphene catalyst based high sulfur content cathode for reversible Aluminum-Sulfur batteries

 Abstract

Aluminum-sulfur (Al-S) batteries are drawing extensive attentions for the development of economical battery systems owing to the high theoretical capacity of 1672 mAh g−1 and low-cost naturally abundant electrode materials, Al and S. However, Al-S batteries are beset by poor reversibility and low actual capacity, only few reversible Al-S cells have been reported until now. In this work, factors affecting Al–S batteries performance are explored and explained, such as the inactive discharge product(Al2S3), polysulfides diffusion and the self-discharge reaction on the surface of SEI-layer-free aluminum anode. And we demonstrate an improved Al–S battery by effectively adjust the voltage window and develop TiN@N-doped-graphene catalyst materials to modify the sulfur cathode. This catalyst is for the first time applied in Al–S batteries and explored its positive effects during the reversible Al-S reactions. Comprehensive electrochemical testing and ex-situ characterization certificates that, in the discharging process, the shuttle effect of polysulfides is suppressed based on the strong adsorption of catalyst; in the charging process, sulfide redox kinetics are promoted and the decomposition reaction barrier is reduced by the catalyst. The Al-S cell delivers an initial capacity of ∼993 mAh g−1 and maintains a capacity of ∼500 mAh g−1 after 200 cycles.

Intercalation of Zinc Monochloride Cations by Deep Eutectic Solvents for High-Performance Rechargeable Non-aqueous Zinc Ion Batteries

Abstract

Zinc ion batteries have been extensively studied with an aqueous electrolyte system. However, the batteries suffer from a limited potential window, gas evolution, cathode dissolution, and dendrite formation on the anode. Considering these limitations, we developed an alternative electrolyte system based on deep eutectic solvents (DESs) because of their low cost, high stability, biodegradability, and non-flammability, making them optimal candidates for sustainable batteries. The DES electrolyte enables reversible Zn plating/stripping and effectively suppresses zinc dendrite formation. Furthermore, in-depth characterizations reveal that the energy storage mechanism can be attributed to [ZnCl]+ ion intercalation and the intermediate complex ion plays a pivotal role in electrochemical reactions, which deliver a high reversible capacity of 310 mAh g–1 at 0.1 A g–1and long-term stability (167 mAh g–1 at a current density of 0.3 A g–1 after 300 cycles, Coulombic efficiency: ∼98%). Overall, this work represents our new finding in rechargeable batteries with the DES electrolyte.

注意事項:

目前疫情期間有開放免親自面談方式，但如果為理工科學生建議還是選親自面談，理工科學生拿行政審查(紅單)機率偏高，選免親自面談還是有可能被要求要去AIT面試。

AIT 內湖新館面試行政審查程序(Administrative Processing, AP, 俗稱紅單) 分享

 2021/11/30申請J-1 VISA 不幸拿了行政審查程序(Administrative Processing)俗稱紅單，在此分享後續流程步驟。

面試當天最後一關是面到一位年輕白人女性，在看完Publication List後當場就吃了一張紅單，並且收走護照和DS2019。

紅單如下，需要補交資料包含 Short Resume (範本紅單後面有，注意存檔格式只能是word檔)、CV、Publication List / Thesis Abstract 與 Adviser Letter

Adviser Letter部分紅單上有寫4個問題，這部分要請你美國學校的指導教授回答，並寫成letter寄回給你

填好後就分開成個別檔案夾帶(不能壓縮成一個檔案)email寄到TaipeiAP@state.gov  ，信件標題記得是你的case number (紅單上有)

後記:

我在寄信隔天早上就收到AIT的來電，通知需要補碩士班的論文英文摘要，因為我是目前在唸博士班還沒有博士論文，AIT因此要求補念碩士班時的論文英文摘要。

在此分享一下AIT的來電是未知明顯示號碼，在等AP這段期間未知來電都要記得接啊。

案件查詢:

可以到美國國務院網站(ceac.state.gov)的線上狀態查詢系統，查詢你的申請案進度。

後續更新:

11/30拿到紅單後，我於12/1補件完畢。

接著就是每天上系統查系統進度，一直都是refused狀態，case last updated一直是11/30，等待中間還卡個聖誕假期，最後於1/10狀態變成Processing。

隔日於1/11狀態變成Issued。然後於隔日1/12早上收到簽證。

Travel and Apartments:

You can use www.511.org/ for traveling in the area.  You can find a link for a local hotel list at https://rde.stanford.edu/studenthousing/community-housing.  under the section About the Stanford Area.  I recommend staying near the street El Camino Real if you do not have a car.  Public transportation along that street is very good.   There is no guaranteed housing for postdocs on the campus, unfortunately.

 

It is sometimes difficult to rent an apartment before you arrive but most postdocs are successful in finding a place close to campus.  Most everyone finds housing within a few days of arrival.  Most use Craig's List http://sfbay.craigslist.org/pen/hhh.  A Stanford site lists rentals and sublets at http://supost.com/.  There are lots of bike paths, particularly in Palo Alto and Menlo Park.  Resources:  https://rde.stanford.edu/studenthousing/housing-resources.

 

While Palo Alto, Menlo Park, and Mountain View are the closest to Stanford, Redwood City, Sunnyvale, and cities further out should be considered.  Bus schedules are at http://www.samtrans.com/system_map.html and http://www.vta.org/getting-around/schedules/bus-rail. There is also a train that follows along El Camino Real.  http://www.caltrain.com/stations.html.   As of September 2014, there are substantial discounts for postdocs on train tickets through Stanford.

Rational design of a polysulfide catholyte electrocatalyst by interfacial engineering based on novel MoS2/MoN heterostructures for superior room-temperature Na–S batteries

Abstract

A suitable electrocatalyst plays an essential role in room-temperature Na–S (RT/Na–S) batteries owing to the more severe dissolution of polysulfides and sluggish kinetics of the conversion of polysulfides during charging and discharging processes. In this study, a novel MoS2/MoN heterostructure synthesized via NH3 annealing was introduced as an electrocatalyst into RT/Na–S batteries to promote the evolution of polysulfides in the catholyte with an initial specific capacity of 703 mA h g−1 and retains 392 mA h g−1 after 300 cycles. The density-functional theory (DFT) calculations, ex-situ XPS and Raman spectra were utilized to reveal moderate anchoring and the fast redox kinetics of polysulfides, significantly enhancing the cycling performance and electrochemical performance of the RT-Na/S batteries when compared with those of the RT-Na/S batteries containing pure MoS2 or MoN as the catalyst. The work provides a new strategy for guiding the design of high‐performance catalysts with manipulated chemical components and optimized adsorption ability.
