個人的「この論文がすごい！2018」 A Personal List of “Breakthrough of the Year” 2018

このBlogへの投稿自体が5年ぶりと、めちゃくちゃ久しぶりですが、またちょくちょく論文や研究のメモなど記録していきたいと思います。

2018年に見つけた新着論文の中で、手法やアイディアの新しさ・重要性に個人的に「！」となって、特にアンテナに引っかかった論文11本のリストです。（学会等で聞いたりして内容は以前から知っていたものも含みますが）

基本的に有機地球化学と同位体地球化学の関連で、けっこうマニアックな論文が多いです。順位は無くて、ざっくりとカテゴリ（水圏有機物、同位体比分析法）で分けました。
