Photodynamic therapy (PDT) applications enable light-controlled activation of drug candidates instead of their constitutive activities to prevent undesired side effects associated with their constant activities. A specific wavelength of light is utilized to enable electron mobility in the chemical structure, which results in differential activities that may alter cell viability and cellular functions. Canonical photodynamic therapy applications mostly focus on cytotoxicity-based antimicrobial and anticancer properties of the PDT agents.

Fly ash has tremendous potential as a nutrient supplement and plays a favourable role in increasing growth performance. Fly ash constitutes above 70% of the whole amount of residues formed in power plants through combustion of coal. The addition of Fly ash in soil improves or changes various physical, chemical and biological characteristics of soil. Fly ash is used for the improvement of the soil texture, water holding capability, density, bulk density, porosity etc. by using in different ratio with soil. For the growth of plant and crop yield fly ash is used as ameliorate in acidic soils.

This study aims to identify types and factors of degradations of kelingkan shawls from the collection of Department of Museums Malaysia located in Kuala Lumpur. The study was carried out through visual observation on twenty-two samples of kelingkan shawls in the museum textile storage room. The findings identify physical damages as the major factor constituting the instability of kelingkan shawls, followed by chemical and biological damages.

The phytohormone ethylene plays a central role in development and senescence of climacteric flowers. In ornamental plant production, ethylene sensitive plants are usually protected against negative effects of ethylene by application of chemical inhibitors. In Campanula, flowers are sensitive to even minute concentrations of ethylene.

Citrus waste includes peels, pulp and membrane residue and seeds, constituting approximately 40–60% of the whole fruit. This amount exceeds ~110–120 million tons annually worldwide. Recent investigations have been focused on developing newer techniques to explore various applications of the chemicals obtained from the citrus wastes. The organic acids obtained from citrus waste can be utilized in developing biodegradable polymers and functional materials for food processing, chemical and pharmaceutical industries.

The growth in the broiler segment is expected to remain strong due to consumer preference for chicken meat. The live market sales of broiler meat still constitute more than 90 % of total sales volume as most consumers prefer freshly slaughtered chicken meat. Modern commercial broilers have a high capacity for lipid biosynthesis because selection strategies have focused on improved body weight gain, breast yield and feed efficiency. Therefore, finding new means to increase the skeletal muscle growth and to reduce excess fat is important for both human health and poultry production.

Agroforestry constitute major chunk of share in replenishing atmosphere, sequestering carbon, and remediating contaminated soils. Phytoremediation is emerging as an alternative agriculture-based technology because word remediation of metal polluted sites can be brought about utilizing the plants to uptake and store contaminants in them. Conventional procedures for cleaning up heavy-metal contaminated sites (i.e. excavation, dredging, and chemical leaching) are all expensive and destructive for the natural environment.

Hydroxyapatite/titania nanocomposites (TiHAp) were synthesized from a mixture of a titanium alkoxide solution and dissolution products of a Moroccan natural phosphate. The simultaneous gelation and precipitation processes occurring at room temperature led to the formation of TiHAp nanocomposites. X-ray diffraction results indicated that hydroxyapatite and anatase (TiO2) were the major crystalline phases. The specific surface area of the nanocomposites increased with the TiO2 content. Resulting TiHAp powders were assessed for the removal of the patent blue V dye from water.

Hydrogel products constitute a group of polymeric materials, the hydrophilic structure of which renders them capable of holding large amounts of water in their three-dimensional networks. Extensive employment of these products in a number of industrial and environmental areas of application is considered to be of prime importance. As expected, natural hydrogels were gradually replaced by synthetic types due to their higher water absorption capacity, long service life, and wide varieties of raw chemical resources.
