Two scientific research posters presented by UST researchers won in the poster contest held on the occasion of the 2023 International Chemistry Congress of the Kapisanang Kimika ng Pilipinas, held from February 15-17, 2023 at the Ƶapp.

The first award-winning research poster was presented by the team of Prof. Christina Binag, PhD, Asst. Prof. Felicidad Christina Ramirez-Penafiel, PhD, Mr. David Joseph Alzate, MSc (PhD Chemistry student), and BS Chemistry alumnus Leighnard Jien R. Felix. The team worked on the project entitled “Polypyrrole and Rice Straw Biochar on Pineapple-Cotton Fabric as Supercapacitor Electrodes for Symmetrical Coin Assembly.” The poster dealt with the concern on the growing global demand for energy that is both clean and renewable, which led to the need to develop energy storage devices. The paper found that biochar had a positive effect on the capacitance of PPY-based fabric electrodes and showed promise as an energy material for supercapacitors.

Meanwhile, the second work involved BSc Chemistry students under the guidance of Prof. Bernard John V. Tongol, PhD and Ms. Hannah Grace Geronimo, MSc (Graduate School student). The student researchers were senior students Ms. Maricar Cruz, Ms. Mary Elyssa Ranoa, and recent alumnus Mr. Matthew Villanueva. They worked on the project “Fuel Cell Electrocatalysts for Ethanol Oxidation Reaction (eor) and Oxygen Reduction Reaction (orr) Based on Pyrolyzed Coconut Husk Biomass.” The study used coconut husk biochar as a low-cost alternative to Pt-based cathode catalysts for oxygen reduction reaction and as a carbon-based support for Pd-based anode catalysts for ethanol oxidation reaction and found the catalysts to provide promising results for ORR and EOR with sustainable, low-cost source of carbon-based materials.

UST Graduate School student David Joseph Alzate won the Best Poster Award during the 35th Philippine Chemistry Congress (PCC) held from September 20 to 24, 2021.


The poster, “Sustainable and environmentally friendly energy storage devices: polyaniline/MWCNT/water hyacinth-cotton, and polypyrrole/MWCNT/piña-cotton textile composites,” was awarded on September 24, 2021, the last day of the conference.


Alzate’s research was co-authored with his adviser, Prof. Christina A. Binag, Ph.D., faculty member Asst. Prof. Felicidad Christina Ramirez – Peñafiel, Ph.D., and College of Science students Rica Angela Benipayo and Leighnard Jien R. Felix.
The 35th Philippine Chemistry Congress is the first fully online gathering of chemists and chemistry enthusiasts in the country, with its theme: “Build Back Better Through Chemistry. “The ‘Build Back Better’ (BBB) concept was defined in the 2016 United Nations General Assembly – the “use of the recovery, rehabilitation and reconstruction phases after a disaster.”


The PCC is the annual conference of chemists and chemistry enthusiasts in the Philippines. First held in 1984, the PCC has since served as one of the biggest gatherings of chemists and researchers from academe, industry, government, and other sectors, where new knowledge in chemistry and allied fields are brought to the forefront.

With the recent rise in wearable electronics and the ever-growing need for clean, renewable, and sustainable energy storage technologies, the demand for textile supercapacitors also increased.

In response to this need, UST Graduate School student Celine Grace V. Causapin, along with UST Research Center for Natural and Applied Sciences and College of Science faculty researchers Dr. Felicidad Christina R. Ramirez and Dr. Christina A. Binag, fabricated a supercapacitor using Abaca-Cotton Fabric (ACF) with Multi-Walled Carbon Nanotubes (MWCNTs) and Polyaniline-Polypyrrole Complex Layer (PAPY) as electrode materials.

This research study by three Thomasian researchers won first place in the Scientific Posters category of the Rapid Fire Competition under the Material Science and Technology Cluster during the 40th Philippine-American Academy of Science and Engineering (PAASE) Anniversary and 2020 Annual Scientific Meeting and Symposium (APAMS), as announced in the closing ceremonies held via Zoom on August 14, 2020.

The study was able to show that “the energy density (1.82 Wh/L) and power density (50.31 W/L) values of PAPY/MWCNT/ACF fall well within the supercapacitor range of the Ragone plot, indicative of an ideal supercapacitor electrode material behavior.” This ACF, though non-conducting, has a high surface area and is suitably porous for supercapacitors, while MWCNTs have high conductivity and stability but low capacitance. PAPY complements the other materials with its good conductivity, improved cycling stability, and high capacitance values.

This means that supercapacitors with these electrode materials are “capable of storing and delivering energy, enough to power a 2.88 V LED” and can be used to power a variety of other low power devices such as PC cards, portable media players and flashlights.

Other potential applications are in off-grid areas or rural areas, as well as assistance during and after major calamities.  This textile-based supercapacitor is highly sustainable with the use of indigenous fabrics like abaca blended cotton.

A scientific poster presenting the use of “Abaca-Cotton Fabric with Multi-Walled Carbon Nanotubes and Polyaniline-Polypyrrole Complex Layer” as a greener approach to energy storage won the top prize in the Scientific Posters category of the Rapid Fire Competition organized by the 40th Philippine-American Academy of Science and Engineering and APAMS 2020 Annual Scientific Meeting, results released on August 14, 2020 revealed.

The work by student Celine Grace V. Causapin, along with faculty researchers and , focused on supercapacitors, “one of the most studied energy storage devices due to their high power density, fast charge-discharge rate, and long-term cycle stability.”

The study aimed to “fabricate and characterize a renewable supercapacitor electrode using abaca-cotton fabric (ACF) with multi-walled carbon nanotubes (MWCNTs) and polyaniline-polypyrrole complex layer (PAPY). The study also aimed to assemble symmetrical supercapacitor full cells using hybrid composites as electrodes.”

According to the researchers, “the physical characteristics of the composites were evaluated using four-point probe conductivity test and thermogravimetric analyses.” Furthermore, their study showed that the “the energy density (1.82 Wh/L) and power density (50.31 W/L) values of PAPY/MWCNT/ACF fall well within the supercapacitor range of the Ragone plot, making it an ideal supercapacitor electrode material.”

Ramirez and Binag are also faculty researchers of the .
