FROM THE EDITOR

On the aspect of scientif ic productivity, it is delightful to know that UP
Diliman is the leading contributor to the Thompson Reuters’ Web of Science
among the autonomous campuses of the University of the Philippines, during
the period of 2008 to 2013 (www.webofknowledge.com). The data illustrate
how the UP Diliman campus has improved in terms of research. We also
would like to congratulate Humanities Diliman for being listed in the Scopus
coverage. With the mutualistic synergy between the parties involved, we
hope that Science Diliman would also be included in the said database soon,
as well as in the Web of Science. Considering the number of faculty and
students in the colleges that offer science and technology graduate courses,
a greater number of scientif ic papers should be expected to be published in
both local and international categories. Nevertheless, the Diliman campus’
feat in scientific productivity leadership among the UP campuses is something
to be distinguished.

We proudly present this issue of Science Diliman, which has been reformatted
in sync with other current journals of the OVCRD-UP Diliman. To celebrate
the University’s continued endeavor for scientif ic productivity, we highlight
articles traversing both life and physical sciences. One article features the
use of advanced instrumentation to quantitatively measure levels of lead
and cadmium in commercial beverages and condiments. Another article
discusses the fabrication of porous silicon for use in photonic applications.
The third article reports on a survey and taxonomy of an ecologically and
economically important brown seaweed. The last article updates readers
on the status and mariculture of abalone f ishery in Pangasinan. This set of
articles emphasizes the impact of research in our University on macro to
micro systems.

We commend the authors and reviewers of the articles for their invaluable
contributions to this journal.
