Abstract:

The increasing needs of disease management have created new standards for diagnostic techniques to include patient-friendliness, sensitive and reliability. However, current analytical methods, either direct-to-customer testing, point-of-care testing, or centralized detection are not able to meet these criteria. This challenge is pronounce in the developing world where the delivery of healthcare is not only beset by limited resources but also by the uneven distribution and concentration of infrastructure in centralized urban facilities. A new two-point separation on-demand diagnostic strategy has been proposed that combines the advantages of convenient onsite sample collection with reliable centralized detection. This new methodology is based on a paper-based mass spectrometry platform that employs stable and cleavable ionic probes as mass reporter; the ionic probes make possible sensitive, interruptible, storable and restorable on-demand detection. This concept is demonstrated for (i) the capture and detection Plasmodium falciparum histidine-rich protein 2 for ultrasensitive malaria detection from non-invasive samples, (ii) diagnosis of onset of liver injury in HIV patients by monitoring the level of alanine transaminase enzyme, and (iii) multiplexed and simultaneous detection of cancer antigen 125 and carcinoembryonic antigen for home-based cancer detection. The strategy also represents a paradigm shift in which portable mass spectrometers can be combined with low-cost paper-based microfluidic devices for direct analysis of large biomolecules.

Abstract:

Superhydrophobic surface has properties of extreme water repellency, showing a very high water contact angle greater than 150° and a very low water drop roll-off angle less than 10°. Water drops on a superhydrophobic surface can roll around freely, while keeping the surface clean by detaching and removing dust from the surface. These surfaces can be easily found in nature, such as a lotus leaf, a dragonfly and a water strider. There are many applications of these unique features such as self-cleaning, drag-reduction, a stain-free fabric, water-oil collecting system, and droplet guiding system. We present methods for the fabrication of stable and transparent superhydrophobic surface and applications of superhydrophobic surfaces.To determine the superhydrophobicity of the surface, usually a contact angle of a water drop on a superhydrophobic surface is measured by sessile drop method. But it is not a simple task because a roll-off angle is very low. We examine the effects of drop size and measuring condition such as the use of a needle or defects on the static contact angle measurement on a superhydrophobic surface. Also, we examine the limitations of Young’s equation, the Wenzel equation, and the Cassie-Baxter equation, which are widely used for superhydrophobic surface.While superhydrophobic surfaces have desired properties for many applications, one of the requirements for the superhydrophobicity is hierarchical morphology with micron-to-nanoscale roughness, which reduces the strength of the structure. SLIPS (Slippery liquid infused slippery surface), similar to the superhydrophobic surface with respect to the low contact angle hysteresis but with a smaller static contact angle, can be much more resistant to the external forces. We also present the fabrication methods and some applications of SLIPS.

Abstract:

In this study, failure analysis of light pole made of fiber reinforced plastics (FRPs) was investigated. The anisotropic properties of FRPs is advantageous in road accidents where these poles save valuable lives undergoing fragile failure. Chemical structure of FRPs light pole was studied using FT-IR. Samples of light pole were tested using dynamic mechanical analysis (DMA) and thermogravetric analysis (TGA) to study the viscoelastic and thermal stability properties respectively. Materials selection for wind load conditions were studied using Cambridge Engineering Selector (CES) program. FT-IR analysis refers to the presence of glass fiber, polyester (PE), natural fiber, coupling agent (N (beta-aminoethyl) gamma aminopropyltrimethoxy- silane). It is found that glass transition temperature (Tg) of PE composite is 76.2 oC as the peak of loss modulus using DMA. Weight percent of glass fiber represent 40% of the total FRPs according to TGA. CES software results showed that the glass fiber – PE composites are valid for light pole manufacture based on material index and wind load with safety factor 4. Delamination of FRPs was detected. This can be attributed to weak interfacial force among glass fiber and polyester in the presence of natural fiber. Hydrolytic breakdown of fiber matrix interface was formed due to presence of moisture (high humidity). This led to loss in performance efficiency of light pole made of FRPs.

Abstract:

A two comparative synthesizing methods, Mechano-chemical solid polymerization (MCSSP) and interfacial polymerization were applied to synthesizing poly(ortho-aminophenol) homopolymer P(oAP) and ortho-aminophenol and meta-phenylene diamine copolymer P(oAP-mPDA). MCSSP is a simple, rabid, free solvent, economically route. In addition; it can be classified as a green and environmental friendly method. The poly(ortho-aminophenol) P(oAP)) and ortho-aminophenol –meta-phenylene diamine copolymer P(oAP-mPDA) were synthesized using developed Mortar Grinder RM200 without using solvents in the preparation process. Moreover, the previous polymers either homopolymer or copolymers were synthesized based on interfacial polymerization method. The comparison between the two techniques were carried out by justifying the following analyses, Fourier transform infrared spectra (FTIR), Ultra violet visible spectra (UV-Vis), X-ray diffraction XRD) ,thermo gravimetric analysis (TGA). Scanning electron microscope (SEM) and (EDS) The band gap energy for the investigated polymers located in the semiconductor materials range which it was found to be 1.74 and 1.95 eV . TGA shows that P(oAP) and P(oAP-mPDA) which synthesized by IP method is thermally more stable than which synthesized by MCSSP method. The crystallinity degree for the investigated polymers which synthesized by IP method is higher than which synthesized by MCSSP method. Polymers which under investigated were applied as inhibitors to the corrosion of metals in the acidic medium.

Abstract:

The purpose of the presented studies was to develop simple and efficient methods for obtaining SBA-15 and MCM-41 materials (2D) with high degree of pore ordering, and containing sulfur atoms, as well as to investigate the influence of synthesis method and reaction conditions on their catalytic activity. Organic sulfur-containing functional groups were introduced into the ordered siliceous matrix by two different procedures, namely "one-pot" synthesis or post-synthetic grafting. The received formulations were evaluated in the terms of physicochemical properties. Low-angle X-ray diffraction (XRD) technique, low-temperature nitrogen adsorption-desorption measurements and transmission electron microscopy were applied for the mesoporosity confirmation in the obtained materials. Moreover, selected samples were subjected to the elemental analysis in order to confirm an incorporation of heteroatoms into/onto the siliceous matrix. In addition, MCM-41 and SBA-15 materials containing sulfur atoms were tested as catalysts in the Friedel-Crafts alkylation. XRD patterns reveales reflexes typical for MCM-41 or SBA-15 mesoporous structure. According to the IUPAC recommendations, nitrogen adsorption-desorption isotherms obtained for all synthesized silicas may be ascribed to type IV(a), characteristic to the mesoporous samples. Results of the elemental analysis clearly point out that synthesis methods employed for obtaining modified mesoporous materials allow to incorporate organic groups containing sulfur. Synthesized materials were successfully applied as acidic catalysts in the Friedel-Crafts alkylation of anisole with benzyl alcohol, resulting in significant conversion and high selectivity to the desired products.

Abstract:

Nanosized Copper-aluminum layered double hydroxides (Cu-LDHs) and Nickel-Aluminum layered double hydroxides (Ni-LDHs) were synthesized using co-precipitation method. LDHs were organically modified by long chain sodium stearate. Polypropylene (PP)/ layered double hydroxides (LDHs) and Polypropylene (PP)/organically-modified nanosized layered double hydroxides (m.Cu- LDHs or m.Ni-LDHs) were prepared by the melt bending of the PP with either LDHs or m.LDHs without any other additives. Thermal stability properties of PP/LDHs composites were also studied by thermogravimetric analysis (TGA).Mechanical properties of the PP/LDHs composites, tensile strength and modulus of elasticity were investigated. The flammability properties were investigated using cone calorimeter test. Intercalation of modified LDHs was determined by XRD in the presence of stearate. Modified LDHs showed a good disperasbility in PP matrix. Thermal stability of PP has been improved up to 6 % using m.Ni-LDHS. Unmodified and modified LDHs decreased the fire growth rate of PP from 10.8 kW/m2.sec to 4.1kW/m2.sec and 4.5 kW/m2.sec. With increasing the percentage of m.Cu-LDH which added to PP, Eg shifted to be located in the semiconductor materials range. The values of Eg are in the range reported for the high efficient photovoltaic materials. So, the present composites could be considered potential materials for harvesting solar radiation in solar cell applications

Abstract:

Clean and safe drinking water is a limited natural resource and a public good fundamental to life and health. The human right to water is indispensable for leading a healthy life in human dignity, but unfortunately these water assets are being depleted immensely all over the world. The aim of the bubble column evaporator (BCE) theme is to develop new concepts, and to improve existing purification technologies in terms of energy and cost effectiveness, which can guarantee high-quality water in the future. The simple bubble column evaporator presents an interesting challenge to our understanding of the detailed processes involved in bubble rise rate, water vapour evaporation and the variable effects of different solutes on bubble coalescence inhibition. Fortunately, the most important and common salt, sodium chloride, acts in solution to inhibit bubble coalescence and that behaviour has been applied to the development of a wide range of useful techniques based on the bubble column evaporator . This complex system has recently been used to develop a novel method for sub-boiling, thermal sterilization, a thermal desalination and its improvement and a new method for the precise determination of enthalpies of vaporization (Hvap) of concentrated salt solutions. A bubble column was used to study sterilization using bubbles of different sizes (mm to cm) produced via bubble coalescence or by inhibiting coalescence through the addition of NaCl. The rapid transfer of heat from small, hot (dry) gas bubbles to the surrounding water was used as an effective and energy efficient method of sterilizing contaminated water. It is shown that the continuous flow of (dry) hot gases, even at 250°C, only heat the aqueous solution in the bubble column to well below sub-boiling temperature and it was also established that coliforms are not significantly affected by even long term exposure to this solution temperature. Hence, the effects observed appeared to be caused entirely by collisions between the hot gas bubbles and the coliform particles close to the sinter, where the gas bubbles were still hot enough (i.e., within 5-10 cm of the sinter surface). It was also established that the use of high air inlet temperatures can reduce the thermal energy requirement to only about 14 % (about 64 kJ/L) of that required for boiling (about 450 kJ/L).

Abstract:

Marine natural products have established themselves as an important source of novel chemical entities that are unlikely to be found in the terrestrial environment. For the past half century, global marine sources have proven to be a rich source of a vast array of new medicinally valuable compounds. In the recent past, there has been an increase in the number of anticancer alkaloids isolated from marine sources, with sponges being an abundant source of chemically and biologically diverse natural products. This is largely due to the improvements in the deep-sea sample collection technology. In this talk, I will present a story of the discovery, synthesis and evaluation of three marine derived tricyclic pyrroloquinone (TPQ) alkaloid analogs as cancer therapeutic agents. Chemical synthesis of these compounds (BA-TPQ, TBA-TPQ, and TCBA-TPQ) has been accomplished and the mechanisms of action (MOA) and structure-activity relationships (SAR) have been investigated. In the past, the complexity of chemical synthesis and the lack of well-defined mechanism of action have dampened the enthusiasm for the development of this class of marine alkaloids. Recent discovery of novel molecular targets for these alkaloids warrant further consideration of these compounds as pre-clinical candidates. We have successfully demonstrated that these compounds attack several key molecular targets, including the MDM2-p53 pathway. In addition to the establishment of synthetic methods and mechanism of action, in vitro and in vivo anticancer activities of these compounds are also demonstrated.

Abstract:

During our studies two different synthetic procedures were applied in order to obtain mesoporous materials of KIT-5 type, containing functional groups with sulfur. Both procedures led to silicas with 3D interconnected cage-like mesoporous structures, what was confirmed on the basis of low-angle XRD and TEM measurements. The resulting XRD patterns revealed reflexes typical for KIT-5 structure. However, diffractograms of materials modified by the co-condensation procedure are characterized by slightly less evolved signals when compared to diffractograms of their counterparts with surface modified by grafting. According to new IUPAC recommendations, the nitrogen adsorption-desorption isotherms obtained for mesoporous KIT-5 silicas may be ascribed to a type IV(a) with a quite sharp capillary condensation step at higher p/p0 values. A broad H2(a) hysteresis loops were also visible, indicating large uniformity of cage-like pores. Results of elemental analysis clearly point out that synthesis methods employed for obtaining modified KIT-5 materials allow to incorporate organic groups containing sulfur. Moreover, according to these results, co-condensation to some extent seems to be more effective than the grafting technique. Synthesized materials were applied as acid catalysts in the Friedel-Crafts alkylation of anisole with benzyl alcohol. The results obtained after 6h of reaction in 100°C (conversion of anisole around 20%) seem to be quite satisfactory. However, some further tests are recommended in order to improve the catalytic performance. Similar observations can be made for the reaction of fatty acids esterification with methanol.
