This is the abstract:
The authors describe a highly sensitive colorimetric method for the
determination of ascorbic acid. It is based on the finding that nanosheets
of reduced graphene oxide that were functionalized with poly(sodium styrene
sulfonate) (PSS-rGO) possess peroxidase-like activity that catalyzes the
oxidization of the substrate 3,3',5,5'-tetramethylbenzidine (TMB) by H2O2 to
form a blue product that can be quantified by photometry or visually. If
ascorbic acid is present, a fraction of H2O2 will be consumed and hence less
blue product (with an absorption peak at 652 nm) will be formed. Ascorbic
acid can be quantified by photometry in the 0.8 to 60 μM concentration
range with a 0.15 μM detection limit. It was successfully applied to the
determination of ascorbic acid in vitamin C tablets and orange juice.
感兴趣的同学请把自己的学术bio 发给我，我帮忙推荐一下。

好不好办看个人背景，签过率你只能问使馆，呵呵。
如果想来就去试试，去试之前好好看置顶说明，使领馆主页，还有版面精华区，你
研究更彻底，你父母签过的概率可能更大一些。
