Novel Sulfonated Poly (Ether Ketone) (Speek) Membrane For Direct Methanol Fuel Cell (DMFC)

The objective of this invention is to develop a novel fulfonated poly (ether ketone) (SPEEK) sa the cation exchange membrane for high performance, high proton conductivity and low methanol permeability for DMFC application. The SPEEK membranes with various degrees of sulfonation (DS) were developed using proprietary mixtures of fuming sulfuric acid as sulfonating agent. Optimizing of the sulfonatin agent mixtures represents the most inventive step in developing this novel membrane for DMFC. This novel step leads to both high ion exchange capacity (IEC) and DS of the membrane within 2 or 3 hours compared to 120 hours using conventional sulfonating process. Overall, this led to the development of high performance SPEEK membrane which exhibited 6 times low methanol crossover and good proton conductivity compared to commercially available membrane. The economics of the novel SPEEK is very appealing since the reduction in methanol is by 60%. In addition, the material cost is also significantly reduced by 10 times as compared to the commercial membrane.

Novel Speek Membrane For Direct Methanol Fuel Cell (DMFC)

Proton Electrolyte Membrane (PEM) plays a crucial role in Direct Methanol Fuel Cell (DMFC) in order to produce high fuel cell performance. The commercial Nafion membrane from DuPont Company possesses outstanding chemical and mechanical stability. However, they may have two major shortcomings which are very expensive (RM 3000/m2) and high methanol crossover/permeability in DMFC. Methanol crossover is particularly troublesome because it leads to Cathode depolarization, excessive water production and possible electrode flooding, and reduction in the fuel efficiency of the entire system.

Novel Method for Real-Time Single Cells Viability Detection using Dual Nanoprobe

Single pulses current measurement on single cells using dual nanoprobe through environmental scanning electron microscope (ESEM)-nanomanipulator system was performed. The nanoprobe was fabricated using focused ion beam (FBI) tungsten deposition and etching processes. The characteristics of the nanoprobe were examined from the energy dispersion spectrometry (EDS) and noise analyses. In this work, for the first time, the electrical property of single cells under their native condition was presented. In order to apply this method for cell viability detection, two types of cells were used, i.e. dead cells and live cells. The results showed that there is a significant difference on the electrical measurement data between the dead and live cells.

Novel Method for Measuring Single Cells Adhesion Force using Nanofork

This novel method measures single cells adhesion force using a nanofork. The nanofork was used to pick-up a single cell on a line array substrate inside ESEM. The line array substrate was used to provide small gaps between the single cells and the substrate. Therefore, the nanofork could be inserted through these gaps in order to successfully pick-up a single cell. The nanofork was fabricated using a focused ion beam (FIB) etching process while the line array substrate was fabricated using nanoimprinting technology. To investigate the effect of contact area on the strength of the adhesion force, two sizes of gap distance of line array substrate were used, i.e. 1 m and 2m. Results showed that the cells attached on the 1 m gap line array substrate required more force to be released as compared to the cells attached on the 2m gap line array substrate.

Novel Method for Fast Single Cells Stiffness Measurement using Buckling Nanoneedle

We proposed a buckling nanoneedle as a force sensor for stiffness characterization of single cells. We performed in situ measurements of mechanical properties of individual W303 wildtype yeast cells using a buckling nanoneedle inside an integrated SEM (ESEM)-nanomanipulator system. Finer local stiffness property of single cells was compared at different pressure and temperature ranges. This detection method of the stiffness variations of the single cells could be applied in the future for fast disease diagnosis based on single-cell stiffness analysis.

Novel H2MC Membrane For Acid/Green House Gas Removal

Natural gas is gaseous fossil fuel consisting primarily of methane (CH4). Generally, natural gas also contains water vapor (H2S and CO2) which are contaminant impurities that reduces natural gas quality. The separation of natural gas contaminants is an important operation in natural gas treating to increase natural gas quality. CO2, present in natural gas needs to be removed in order to increase heating value of the gas, preventing corrosion of pipelines and gas processing equipment, prevent crystallization of CO2 which can cause process blockage and reduce the green house gas emission which harmful to environment.

Natural Palm Oil As A New Power Transformer Insulation Material

Electrical insulating liquids are used abundantly in a variety of components of power system networks such as transformers, power cables and bushings. Petroleum-based mineral oil is the most commonly used oil in the electric power industry. However, the oil is non biodegradable and can contaminate soil and water when serious spill take place. Therefore, it is vital to find a better alternative liquid insulating material which is environmental friendly. One of the alternatives is to utilize palm oil as electrical insulating material. Malaysia as the world's largest producer and exporter of palm oil will have a good opportunity if palm oil can be used as electrical insulation, particularly in power transformer. Natural palm oil has the properties of biodegradable whereby it can reduce the environmental impact and less toxicity to living organism. It has also being shown that the natural palm oil has good electrical and chemical properties having the potential to replace the existing mineral oils.

Nanostructured Coupled Semiconductor Photocatalyst (NCSP)

NCSP is a novel photocatalyst with high efficiency under visible light (60%), low recombination rate of the photogenerated hole-electron pairs, high surface area, hydrophilic, demonstrates excellent adsorption ability towards the nonpolar organic compound and may be easily recovered. NCSP is prepared by impregnating coupled semiconductors on nanostructured material support. Through the synergy effect of coupled semiconductors, the charge separation of the photoexcited electron-hole pairs is greatly increased and thus results in low recombination rate which will in turn enhance the photocatalytic activity of the photocatalyst. The high surface area provided by the nanosupport enables more active sites to be present and enhances the recovery of NCSP.

MozzieRID: Natural Aromatic Skin Wipe

The novel feature of this invention is the formulation itself where in this skin wipe consisted of single repellent oil only plus a Hibiscus gelatin to overpower human odors and help to cool body heat during perspirancy, thus deflecting mosquitoes away. The bioactive compound of concern cinsisted in this invention is geraniol. Geraniol is extracted from Pelargonium radula which is widely available locally and known as Jeremin. This particular oil posed a styptic or astringent effect which contracts the tissues or blood vessels when bleeding. Moreover, a Hibiscus gelatin is added to the formulation to coll down the body heat, which produced carbon dioxide (CO2) plus heat wave from the skin via transfer mechanism. A skin wipe is usually comprising a low cost and biodegradable porous sheet (cellulosic fibrous) impregnated with an oil-in-water emulsion. This skin wipe contained a polymeric bead which is useful for treating the human skin or environmental surfaces by providing controlled released of functional ingredient. A search for an alternative effective insect repellent, which is also user friendly, mobile, safer and cheaper than the existing one seems are able to be fully developed and justified.
