劉生,全力支持你。不用太介懷那些人的花生言論。我最討厭那些只懂攻擊同路人的人,因此我已經unsubscribe 曬嗰啲有炒過花生的,什麼冇格仔,隨時論,吳志森,傑斯等等,我絕對會繼續支持城寨,我們現在最重要的是有養份獨到的政論分析,而不是那些只懂針對自己人嘅 so call KOL。希望你繼續努力,但也需爭取時間休息。我也是養狗之人,非常體會你們兩夫婦對鄺阿里的關懷。
Not only is it possible to hand-grind nanoparticles, but it is done in many research laboratories every single day. Some materials cannot be hand-ground, due to their chemical reactivity (would oxidize to nothing) or some other factor, but many can.

I remember researchers have been using tapes to fabricate nanomaterials,. Simply pressing the tape on the material surface and pulling it off will give you some nanomaterials. The tricky part was to prove the nanomaterial was useful in any sense.
