Research Center for Natural and Applied Sciences


The UST Research Center for the Natural Sciences and Applied Sciences (RCNAS) functions as the Science and Technology research arm of the University. It brings together researchers of various disciplines namely, biology, chemistry, biochemistry, microbiology, physics, engineering, pharmacy, and food technology – all working towards the objective of contributing to an improved quality of life and sustained viability of the environment.

Research Programs

Advanced and Nano Materials

New and nanostructured materials are developed and characterized for electrochemical energy conversion and storage management devices. The development of fuel cells with nanostructured catalyst allows the efficient conversion of chemical energy to electrical energy for possible applications in electronic devices and transportation. The development of supercapacitors with new electrode materials like conducting polymers and metal oxides with carbon support materials allows the storage of large amount of energy and discharge it quickly. Phase change materials (PCM) which are energy storage media are used as thermal storage devices for cooling or heating load management and augments the utilization of renewable but intermittent energy sources.

New polymers are developed and characterized for controlled drug delivery system that allow the prevention of drug toxicity and maximizes drug therapeutic effects.

The UST Research Center, better known as the Research Center for the Natural Sciences (RCNS), was conceived during the 350th Anniversary of the University and was confirmed on 31 March 1962 when its rules and regulations were approved by the Economic Council.

The Research Center’s main purpose was to give research opportunities to the faculty members of the University in an attempt to reinforce teaching capabilities with their research experience. Two major areas of exploration were initially considered, the Cultural Sciences and the Experimental Sciences. The only existing criterion for choice was “social significance.”

After years of operation, the Research Council realized that resources would be better maximized by focusing on projects under the umbrella of the Natural Sciences.  So in 1986, with the approval of the Rector, the Center was renamed as the UST Research Center for the Natural Sciences. This Center operates independently from the other research entities of the university which have been set to cater to the other disciplines. To be able to bring the outputs of researches to the community and to the market for possible utilization and application, the University renamed it as Research Center for the Natural and Applied Sciences (RCNAS) in 2009.

RCNAS through five decades of existence. The productivity of the researchers in the various disciplines, the recognitions accorded the Center and research awards received for exemplary research from external agencies, both local and international, are the strengths of the Center that sustained it through the years. The strong ties the Center bridged among the local, national, and international partners marked the global acceptability of the Research Center and the researchers.  The research grants received for the conduct of disciplined research in specific areas and patents awarded from products of research are the measures of trust and recognition the Center has from the local and international communities and Granting bodies.
