I read with interest the article entitled ＂Concurrent removal of intravitreal lens fragments afterphacoemulsification with pars plana vitrectomy prevents development of retinal detachment＂ by Chalam et al . In this study, none of the patients developed retinal detachment （RD） during the one-year follow-up after concurrent removal lens fragments following phacoemulsification with pars plana vitrectomy （PPV）. The authors suggested that concurrent PPV for retained lens fragments after cataract surgery might prevent development of rhegmatogenous retinal detachment （RRD）, because early PPV prevents development of intraocular inflammation and inhibits vitreous contraction, a common cause of retinal tears and detachment.

This paper emphasizes the importance of the denomination of financial assets rather than trade invoicing as a long-term determinant of an international currency. China needs to liberalize and open its financial system and make the RMB fully convertible, and to adopt a moreflexible exchange rate system to speed up its currency internationalization, for which China could follow either a global or regional approach. The global approach is a riskier and more unpredictable strategy because it would demand a scope and timeframe of financial liberalization that is likely to be beyond China＇s institutional capacity over the coming decade. There are two options that could be taken in following the regional approach. One is creating an ASEAN＋ New 3 （the Chinese Mainland, Hong Kong, and Taiwan） RMB bloc and the other is liberalizing China＇s financial industries and internationalizing the RMB by playing a leading role in East Asia＇s economic integration within the framework of ASEAN＋ 3, This paper concludes that the latter is a more realistic and effective approach for China.

The etching effect of ammonia （NH3） on the growth of vertically aligned nanotubes/nanofibers （CNTs） was investigated by direct-current plasma enhanced chemical vapor deposition （DC-PECVD）. NH3 gas etches Ni catalyst layer to form nanoscale islands while NH3 plasma etches the deposited amorphous carbon. Based on the etching effect of NH3 gas on Ni catalyst, the differences of growing bundles of CNTs and single strand CNTs were discussed; specifically, the amount of optimal NH3 gas etching is different between bundles of CNTs and single strand CNTs. In contrast to the CNT carpet growth, the single strand CNT growth requires shorter etching time （5 min） than large catalytic patterns （10 rain） since nano dots already form catalyst islands for CNT growth. Through removing the plasma pretreatment process, the damage from being exposed at high temperature substrate occurring during the plasma generation time is minimized. High resolution transmission electron microscopy （HTEM） shows fishbone structure of CNTs grown by PECVD.

A facile design of Pt nanostructures from submonolayer to monolayer has been realized by ion adsorption-in situ electrochemical reduction on Au nanoparticles supported on multiwall carbon nanotubes （CNTs）. The as prepared Au@Pt/CNTs catalysts display coverage-specific electrocatalysis. Au@Pt/CNTs with low Pt coverage is inactive towards methanol oxidation whereas it oxidizes formic acid effectively through a direct pathway with mass specific activity 90 times that of a commercial Pt/C catalyst. Due to its inertness to methanol, it shows high performance in the oxygen reduction reaction （ORR） with high methanol tolerance. In contrast, simply increasing the Pt coverage to above 40% switches the formic acid oxidation process to both direct and indirect catalytic pathways, and also results in high methanol oxidation activity.

magnetotactic Tetrahymena pyriformis GL （T. pyriformis） cells were created by the internalization of iron oxide nano particles and became controllable with a time-varying external magnetic field. Thus, T. pyriformis can be utilized as a cellular robot to conduct micro-scale tasks such as transportation and manipulation. To complete these tasks, loading inorganic or organic materials onto the cell body is essential, but functionalization of the cell membrane is obstructed by their motile organelles, cilia. Dibucaine HC1, a local anesthetic, removes the cilia from the cell body, and the functional group would be absorbed more efficiently during cilia regeneration. In this paper, we characterize the recovery of artificial magnetotactic T. pyriformis after the deciliation process to optimize a cellular robot fabrication process. After sufficient time to recover, the motility rate and the average velocity of the deciliated cells were six and ten percent lower than that of non-deciliated cells, respectively. We showed that the motile cells after recovery can still be controlled using magnetotaxis, making T. pyrfformis a good candidate to be used as a celIular robot.
