1. Environmental friendly carrier material for nifedipine as hypertension drug

E. Budianto; S.H. Astuti

Articles in Press, Accepted Manuscript, Available Online from 06 May 2020

Abstract
  Nifedipine is a hypertension drug must be consumed three times a day due to its low oral bioavailability. One way of developing a controlled drug delivery system is making nifedipine microcapsules by using environmentally friendly polymers of polylactic acid and polycaprolactone via the evaporation method ...  Read More

Volume 5, Issue 2 , Spring 2019, , Pages 213-224

http://dx.doi.org/10.22034/gjesm.2019.02.07

Abstract
  Carbamazepine is one of the hydrophilic compounds identified in aquatic environments. Due to toxicity and bio-stability of this psychotropic pharmaceutical in the environment and humans, its removal efficiency and mineralization are important. In this study, synthesized Fe@Fe2O3 nanowires were applied ...  Read More

7. Parthenium hysterophorus: Novel adsorbent for the removal of heavy metals and dyes

S.A. Bapat; D.K. Jaspal

Volume 2, Issue 2 , Spring 2016, , Pages 135-144

http://dx.doi.org/10.7508/gjesm.2016.02.004

Abstract
  Heavy metals and dyes are major contributors in contamination of water streams. These contaminants enter into our eco- system, thus posing a significant threat to public health, ecological equilibrium and environment. Thus a combined discharge of these contaminants results in water pollution with high ...  Read More
