Carbon Nitride Polymer Nanocomposite Anion Exchange Membranes
(Polytechnic University of Puerto Rico, 2019-08-19)
This work proposes the fabrication of novel polymeric membranes to overcome some limitations of the existing AEMs, such as their low OH conductivity and poor chemical stability in KOH
Use of Plastic as a Replacement of Fine Aggregates in Concrete Admixtures
(Polytechnic University Of Puerto Rico, 2019)
Although current legislation established that 35% of plastic waste must be recycled on Puerto Rico (PR), actual figures are far below this target (ADS, 2017). Plastic materials have a great impact on the environment since ...

The Evaluation of the National Operational Excellence Index impact over the Private Sector Sustainability in Puerto Rico
(Polytechnic University of Puerto Rico, 2018)
During the past decade, the World Forum Competitive Index (WFCI) from
the Island has dropped from 36 (2008) to 32 (2015). This drop is being
aligned with the loss of resources from federal tax laws and high
utilities/ ...
