Seaweed-Based Air Freshener Gel

Dr. Montaño and his team developed a seaweed-based air freshener with a characteristic gel-like texture. The low-cost air freshener makes use of the whole seaweed instead of the extracted polysaccharide leading to lower production cost. The base allows a slow release of the essence thus prolonging its shelf life. Unlike the fresheners commercially available, the seaweed-based air freshener can be divided into shapes and sizes for easier packing and utilization.

Two Color (Two Photon) Excitation with Focused Excitation Beams and a Raman Shifter

Dr. Saloma and his team have invented a method for inducing highly localized light absorption in materials via two-color (two-photon) excitation (2CE). Compared to conventional methods, including two-photon single color excitation, two-color fluorescence excitation results in a higher spatial resolution. Furthermore, it is robust against effects of two-beam interference and breakdowns in confocality of the focused excitation beams. This technique can be applied to two-color fluorescence microscopy of optically thick and irregularly shaped biological samples.Optical beam-induced current imaging is a failure analysis technique for determining the presence of defects and discontinuities in an integrated circuit. The advantages of two-color excitation can be extended to it for the enhancement of resolution and image contrast. This technology is a key component of a practical 2CE microscope.

Applications: biomedical imaging, failure analysis in semiconductor industry

Titanium Nitride Thin Film Formation on Metal Substrate by Chemical Vapor Deposition in a Magnetized Sheet Plasma Source

Through the advanced technology developed by Dr. Ramos and his research team, it is now possible to enhance the lifetime of tools through coating. A magnetized sheet plasma source provides a wear-resistant titanium nitride (TiN) tool coating at less than a quarter of the cost of carbide coating and similar techniques. The coating process is superior to other techniques because it is relatively fast and does not require very high temperatures that could damage the material being coated.

Applications: cutting tools manufacturing industry, aerospace components, automotive parts, broaches, decorative accessories, dental instruments, door hardware, eyeglass frames, firearms components, food processing equipment, hobs, jewelry, marine hardware, medical devices, pharmaceutical equipment, plastic molds, plumbing fixtures, precision gears, sporting goods, surgical implants and writing instruments

Process for the preparation of mitoxantrone

The out-of-patent anticancer drug mitoxantrone was chemically synthesized via a different synthetic route from that published in the literature. The synthesis was achieved and optimized in a Philippine setting, considering the availability of reagents and the limitation of experimental setups for chemical synthesis. Mitoxantrone has the same efficacy as the standard, widely used anticancer drug doxorubicin, except that mitoxantrone exhibits no or less cardiac toxicity, because unlike doxorubicin, it is not a glycoside.

Method for Generating High-Contrast Images of Semiconductor Sites via One-photon Optical Beam-Induced Current Imaging and Confocal Reflectance Microscopy

Dr. Saloma and his team developed a microscopic imaging technique that effectively discriminates between semiconductor and metal materials in an integrated circuit. This was done by utilizing one-photon optical beam-induced current (1P-OBIC) and confocal reflectance images, which are both generated using the same excitation laser beam. Compared to the two-photon optical beam-induced current imaging that also generates high-contrast images of semiconductor sites, the hardware support for this 1P-OBIC procedure is significantly cheaper. Using this principle in a combined OBIC and confocal microscope system allows for effective visualization of semiconductor integrated circuits, which is useful for failure analysis and other applications.

Applications: semiconductor industry, academic research insititutes

    Method for detecting TAG-72 using CC92 and CC49 monoclonal antibodies and use thereof for cancer diagnosis, prognosis and monitoring

    A prototype cancer immunodiagnostic kit was developed which detects the presence of the pancarcinomic tumor antigen TAG-72 in serum. This ELISA sandwich method makes use of the monoclonal antibodies against TAG-72, namely: CC92 as capture antibody and CC49 as detecting antibody. When TAG-72 levels are measured in parallel with CEA levels (standard cancer diagnostic), monitoring and prognosis of cancer patients can be improved.

    In vivo method for selecting antibodies, their derivatives and antibody-mediated therapies against breast cancer

    A mouse tumor model was developed that allows the preliminary testing of candidate therapeutic antibodies and antibody conjugates targeted to the human pancarcinomic tumor antigen TAG-72. A mouse tumor antigen, expressed on the surface of mouse mammary tumors growing in mice, is detected by the TAG-72 monoclonal antibody CC49 by immunohistochemistry. The mammary tumor in mice regresses when intravenously injected with CC49 or a CC49-drug conjugate.
