Random sampling of research papers from Philippine-based researchers

Sharing a random sampling of this week’s research papers from Philippine-based researchers. Jaculbia, et al, reported an enhancement of terahertz emission from SI-GaAs and n-GaAs wafer surfaces by more than a factor of 2 and 4, respectively, in Applied Surface…

Enhanced performance of superconducting thin films by ion milling

YBa2Cu3Oy (YBCO) belongs to a class of oxide materials collectively referred to as “high-Tc (critical temperature) superconductors (HTS),” i.e., materials that exhibit superconductivity above the boiling point (77K) of liquid nitrogen. However, as these materials are typically brittle, in order…

Research productivity in education and psychology

In a recent paper entitled “Research productivity in education and psychology in the Philippines and comparison with ASEAN countries” published in Scientometrics, Lorelie Vinluan (University of the Philippines, Diliman) examined the country’s research productivity in the field of education and…

Beam shape corrections to the Law of Reflection

The law of reflection states that with respect to an imaginary line that is perpendicular to the surface of the reflecting object, light will be reflected at the same angle and at the same plane as it was incident.  Euclid,…

Research productivity and the knowledge economy

Several years ago, we reviewed the scientific publication performance of the Philippines and some of its neighboring countries including Indonesia, Malaysia, Thailand, and Vietnam. Using the Science Citation Index Expanded, we looked at the number of publications coming from these…

Controlling dengue from within

Dengue fever is a mosquito-borne viral disease that’s becoming an increasing problem in tropical and subtropical regions. It is an infection that causes a severe influenza-like illness, and sometimes a deadly complication called dengue haemorrhagic fever. Some of the symptoms…

Viability of production of biodiesel and biogas from microalgae: A net energy analysis

Recently, there has been a growing interest in finding alternative forms of energy. This is mostly driven by increasing prices of oil, concerns over greenhouse gases emission from fossil fuels, and some form of government subsidies. One of the alternatives…

Impact of climate change in the Philippines

To understand better the possible effects of climate change in the Philippines, it is critical to collect, record, collate and analyze all data and information with possible links to climate change so that appropriate scenario-building and extrapolations can occur. The…
