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 ...
Supercapacitor Electrodes Based on Modified Carbon Nitride for Applications in Renewable Energy Storage
(Polytechnic University of Puerto Rico, 2019-08-19)
Supercapacitors are rechargeable electrochemical energy storage devices, whose can store much larger amount of electrical energy in the interfaces between electrodes and electrolyte.
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
