trash in korea: everything you need to know about garbage,if you live in korea, you already know that korea is pretty strict with its recycling policies. korea is pretty specific with the kinds of trash it recycles: biodegradable waste, pet bottles, other plastics, batteries, bottles, and sometimes more. recycling in korea differs according to the processing of local governments.
coagulation, flocculation and clarification of drinking water
most water treatment practices including coagulation, flocculation and clarification, date back hundreds and in some cases thousands of years. references as old as 2000 b.c describe what we know today as coagulation. figure 1: earthen jars used to store water “it is good to keep water in copper vessels, to expose it to sunlight and

- Does graphene improve the biocompatibility of polyacrylamide hydrogels?
- The main conclusion of this work is that graphene plays an important role in improving the biocompatibility of polyacrylamide hydrogels, allowing neuronal adhesion.
- How are polyacrylamide hydrogels prepared?
- Pure polyacrylamide hydrogels were prepared using Am, MBA as cross-linker and KPS as initiator. Am was initially dissolved in ultrapure Milli-Q water (200 mg mL −1) together with the MBA (0.2 mg mL −1 ). The solution was homogenised by stirring and mild sonication.
- Does 3D polyacrylamide scaffold support neuronal cell growth and activity?
- We tested the 3D polyacrylamide scaffold efficacy to support neuronal cell growth and activity and we compared one of the nanocomposite sample (AMG0.2) to its blank AM counterpart. Although different in the pore size ranges, both materials have pores within dimensions known to permit cell survival in culture 4, 52, 53.
- Which reagents were used in the synthesis of acrylamide?
- Acrylamide, ammonium persulphate (APS), N, N, N′, N′-tetramethylethylenediamine (TMEDA), N, N′-methylene diacrylamide (BIS), and dopamine hydrochloride were purchased from Aladdin (China). CNTs were provided by Chengdu Organic Chemicals (China). All reagents were used as received without further purifications. 2.2.
