Purifying Used Cooking Oil

This investigatory project determines the possibility of purifying used cooking oil using sedimentation method. The activated carbon was also used in the experiment to absorb some dissolved substances in the oil. There were three different setups used in this study namely; Setup 1 (sedimentation was done once); Setup 2 (sedimentation was done twice); and Setup 3 (sedimentation was done thrice).

Used Cooking Oil as an Additive Component of Candle

The study aims to produce a low-priced, high-quality candle by using used cooking oil as a major component. The following candle compositions were used: 100 percent paraffin wax; 90 percent paraffin and 10 percent oil; 80 percent paraffin and 20 percent oil; 70 percent paraffin and 30 percent oil; 60 percent paraffin and 40 percent oil; 50 percent paraffin and 50 percent oil. The firmness, texture, and light intensity of the candles were tested and compared.

Cellular Phone as Electrical Device Activator

This study aims to focuses on the development of a remote control that will function in activating any desired electrical device out of a common gadget, the cellular phone.

The researchers developed a remote control using the widely used medium for communication, which is the cellular phone. This device will operate as a remote control that can activate different electrical devices regardless of the distance, because cellular phones operate through microwaves as its medium. Since the device can operate in very large distances, a confirmation for the activation of the electrical devices will be obtained. This device will function as a remote control to activate desired electrical device anywhere, anytime.

Elastomeric Grating for Wavelength Switching

Elastomeric Grating for Wavelength Switching in Optical Communication Systems. A diffraction grating was fabricated from an elastic polymer. It was patterned after a plane reflection grating with a pitch of 1,200 lines/mm. It was characterized using HeNe laser to verify grating properties. Angular scanning as a function of applied strain was observed for two individual wavelengths. Intensity of the fiber output was optimized as an application of angular scanning in fine alignment. Beam profiles showed consistency of first order diffraction intensities at different levels of strain. This showed that the elastomeric grating’s efficiency is independent of strain. The elastomeric grating’s variable pitch can be of immense utility in optical communication systems.
