Dr Jose Hernandez Santos


Associate Professor, Faculty of Science


Dr Jose H Santos obtained his PhD in Chemistry from La Trobe University, Australia, in 1996 under the supervision of Professor Alan Bond. After serving as an Assistant Professor at the University of the Philippines, he worked as a postdoctoral scientist at Dublin City University and AIST Japan where he nurtured and developed his research interest in electroanalytical chemistry. He joined UBD in 2004 as a Senior Lecturer and is currently an Associate Professor, actively involved in the development of analytical methods that are low cost and environmentally friendly. He is also a Chartered Scientist and a Chartered Chemist member of the Royal Society of Chemistry in the UK. His current research involves fabrication of electrochemical sensors for detection and analysis of various substances in foods and beverages as well as in the environment. These sensors are not only environment friendly but are also low cost and easy to use.

Construction and Evaluation of Homemade Smartphone Spectrophotometer in Studying Beer’s Law

Mobile phones have become part of our day-to-day activities and they are constantly changing the way we communicate and learn. The portability and ubiquity of smartphones has provided new possibilities for the chemistry laboratory to support blended learning and provide opportunities for entrepreneurial skills and environmental awareness. In this project, the students will design, build and test homemade spectrophotometer using a mobile phone and simple components with creative designs. The performance of the constructed prototype will be compared with commercial spectrophotometers currently being used in the laboratory in studying Beer's Law and absorbance spectrometry. This project will be part of a bigger collaborative project with a Computer Science final year student who will be in charge of developing the mobile Apps specific for the designed prototype.

Construction and Evaluation of Solid-State Ion Selective Electrodes (ISE) Prepared from Pencil Leads Coated with Conducting Polymers and Sol-Gel Membranes

The aim of the project is to fabricate ISE’s from graphite pencil leads through electrode modification with conducting polymers as well as sol-gel procedures. The fabricated electrodes will be evaluated based on their potentiometric response with pH and various cations and anions.

Spectroscopic and Electrochemical Properties of Selected Native Plant Species from Brunei

Many plant species indigenous to Brunei are unexplored in terms of their usefulness as functional food and medicine or as a source of compounds with special properties such as pigments for solar cell applications. This study provides a preliminary investigation on the availability of chemical components in plants that have special properties that may be utilised for various applications. The students should be able to integrate the theory and practice of spectroscopy and electrochemistry in solving real world problems.
