Bee nests inspire UP scientists to make new ‘smart’ materials

Bee nests are a marvel of natural engineering that have inspired human engineers and inventors for centuries. Now, Filipino researchers are investigating ways to create porous materials that not only mimic the strengths of beehives but are also able to selectively trap microparticles. These new materials have potential uses in everything from water purifiers to medical sensors.

Jonathan Patricio, Gillian Kathryn Yap, Jose Jesus Gayosa, and Dr. Susan Arco of the UP Diliman College of Science’s Institute of Chemistry (UPD-CS IC) and colleagues from the Ateneo de Manila University (ADMU) were able to control the physical properties of porous polyvinyl chloride (PVC) films by adjusting the drying temperature used in the manufacturing process.

The PVC is formed around droplets of water which, when they evaporate, leave a pattern of microscopic holes reminiscent of a bee’s nest. Such honeycomb structures have long been recognized for their engineering applications:

“One of the most interesting structures inspired by nature is the honeycomb pattern… Its unique properties and structure inspired the construction of light and robust aircraft and spacecraft, protection gear, panels, packaging, and cushioning because of an ability to absorb impact and energy,” the researchers explained in their paper.

“The repeating units of a honeycomb pattern can also effectively trap particles and impurities thus making them a promising structure for air and water filters,” they added.

The UP researchers investigated the difference in the honeycomb structure of PVC films that were dried at room temperature (a) and at temperatures above 80°C (b). (Photo credit: M. L. M. Budlayan)

The researchers also explored the wettability of the various honeycomb PVC materials they created, as well as the potential of selectively trapping microparticles by subjecting the honeycomb to an electric charge.

The study “opens the possibility of integrating polymeric honeycomb structures into substrates used for microparticle trapping, sensing, and other related applications,” the researchers concluded.

The University of the Philippines Alumni Council, the advisory body of the UP Alumni Association (UPAA), resolved to fully support Ambisyon 2040, the government’s program for long-term economic growth.

The council made the resolution during its annual meeting with the theme, “Handog sa Pamantasan, Pag-alay sa Bayan”. With resource person for the resolution, Secretary Arsenio Balisacan of the National Economic and Development Authority (NEDA). The meeting was held at the Ang Bahay ng Alumni in UP Diliman on August 18.

Balisacan, this year’s UPAA Most Distinguished Alumnus, explained Ambisyon 2040 in his UP Alumni Council Meeting lecture, “Social and Economic Transformation for Inclusive Philippine Development”. The program envisions human development as “matatag, maginhawa, at panatag”.

He emphasized that a “rapid, sustained, and inclusive growth is a necessary condition for the Philippines to become a predominantly middle-class society” by 2040. Balisacan spoke of a target annual growth rate of 6-8.5%.

While maintaining that the trick to growth is in the hands of the private sector, particularly through innovation and actively targeting bigger markets, government must raise its spending to achieve the targeted growth rates. Balisacan said government must sustain spending on infrastructure at 5-6% of GDP (gross domestic product). He said NEDA would continue monitoring and advising slow spenders in government.

Balisacan further highlighted the need for government to enhance society’s ecosystem for research and development and innovations, requiring, among others, robust partnership among government, private sector, and the academe.

The UP Alumni Council through Atty. Raul Reyes, the UPAA legal counsel and Chair of Council’s Resolution Committee, presented a draft of the resolution, which stated that the UPAA “will fully support the [NEDA’S] program for long-term economic growth called the Ambisyon 2040”.

It further resolved that the UPAA “will support and participate in the academe’s role in the government’s plan for social and economic transformation in order to raise the quality of investments vis-a-vis employment” and that it “will actively contribute to and encourage academic programs that will produce graduates who are eligible to provide efficient human capital to the government’s programs”.

The UP Alumni Council is composed of: University officials, deans and directors; past and present members of the UP Board of Regents; the current UPAA Board of Directors and the current officers of the UPAA chapters; the Distinguished Alumni Awardees; and other persons as may be designated by the UPAA Board of Directors.

It holds the annual meeting in order to draft and pass resolutions presented for endorsement to the general UPAA membership during the General Homecoming. These resolutions are then submitted to: the UP alumni in Congress and in the Senate for aid in legislation; the Board of Regents; and appropriate government and private agencies for reference in formulation of policies.
