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.
Glow Discharge Plasma Sterilization of Prokaryotic Microorganism Through Electrostatic Plasma
(Polytechnic University of Puerto Rico, 2019-08-19)
Sterilization/disinfection of target bacteria – Bacillus Subtilis – is investigated using plasma sterilization process which involves both Dielectric Barrier Discharge Plasma (DBD) and Glow Discharge
Plasma. The purpose ...
Alternatives for Processing Plastics with Recycle Codes from 3 to 7
(Polytechnic University of Puerto Rico, 2019-08-19)
Solid waste management represents a challenge for Puerto Rico. According to the Department of Natural and Environmental Resources (2019), more than half of the landfills have a closure order and only type one and two ...

(Polytechnic University of Puerto Rico, 2019-08-19)
This research project was intended to assess the ability for Puerto Rico’s power grid administrative authorities to respond to a cyberattack like the one documented in Ukraine in December 2015 The researcher gathered ...
Distributed Electric Propulsion
(Polytechnic University of Puerto Rico, 2019-08-19)
This investigation focused on predicting aerodynamic improvements obtained when air is blown over a wing by six propellers distributed equally along the wing’s span The purpose was to validate a method to implement Distributed ...
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
