How you write your resume for looking a job in US

講者: 馬紹銘博士

2018/4/25
不要超過1頁(HR篩選履歷只會看10秒)，字體最小10，字型用Times New Roman
個人聯繫資訊只放EMAIL，不要放照片、個人住址等資訊(美國是個有淺在歧視文化的國家，透漏太多資訊會被先排除，EX: 有些會歧視亞裔、老人、女人)
英文姓名要注意，最好羅馬拼音方式選台灣的(但還是要跟護照一樣)，不要選大陸的，會被當成大陸人(大陸人美國居留證很難拿，有些公司會先刷掉大陸人)
剛出社會的上，由於無工作經驗與實績，放成績為主(GPA最好3.5以上)，其次放發表/專利。社團或旅外經驗加分幫助不大(除非你找管理或銷售部門的職缺)。
如果有工作經驗的話，先前的公司最好待2年以上在跳槽(最好有升遷的紀錄)，否則會被認為抗壓性差或對公司忠誠度有問題。如果離職的話盡量不要有太長的gap year。
應徵不同公司或不同職缺的話，最好重寫一份符合該公司貨職缺的resume，千萬不要一份resume走天下，這是大忌!
寫resume字裡行句不要有太多highlight，會有反效果。

Earth Abundant Transition-Metal Based High Entropy Alloys (HEAs) Nanorod Arrays Prepared By Glancing Angle Deposition System (GLAD) Toward High Performance Electrocatalysts for Water Oxidation Reaction

Abstract

High-entropy alloys (HEAs) have recently aroused increasing research enthusiasm due to their attractive properties, such as easy formation of nano-size precipitates, high hardness, good fatigue with fracture resistance, good thermal stability, excellent corrosion resistance and tendency to form simple solid solutions with face-centered cubic (FCC) and body-centered cubic (BCC) crystal structure. However, to the best of our knowledge, the growth of HEAs nanostructures and its electrocatalytic properties have not yet been reported. Herein, we demonstrate for the first time, HEAs nanorod arrays on stainless steel by glancing angle deposition system (GLAD) as electrocatalysts for oxygen evolution reaction (OER). This electrocatalysts exhibited excellent OER activity and durability. Specifically, a low overpotential of 302 mV can be achieved at a current density of 10 mA cm−2, yielding a Tafel slope of ~28 mV dec-1 in 1 M KOH. Moreover, it can be operated more than 500 cycles of a linear voltammetry (LSV) scan at a scan rate of 5 mV/s. The outstanding performances is attributed to the high surface area of nanorod arrays. This work opens up new great potential in the field of energy based application such as batteries, supercapacitors, and electrocatalytic applications.
