Phase transition is a natural phenomenon happened around our daily life, represented by the process from ice to water. While melting and solidifying at a certain temperature, a high heat of fusion is accompanied, classified as the latent heat. Phase change material (PCM) has been widely applied to store and release large amount of energy attributed to the distinctive thermal behavior. Here, wit...

 Methods: The sponge carnosus was collected during low tides West Coast Mumba...

Voacanga africana Stapf which belongs to the family, Apocynaceae is among useful medicinal plants of West Africa. The present study investigates antibacterial and antioxidant properties aqueous extracts obtained from raw fermented V. africana. One portion was subjected submerged fermentation for 7 days. Aqueous samples were using standard methods. Antibacterial effect exracts assessed by agar w...

We have investigated how four different pour point depressant (PPD) polymers affect the pour point transition in mixtures of a single pure wax in a solvent. We used either n-eicosane (C20), CH3(CH2)18CH3, n-tetracosane (C24), CH3(CH2)22CH3 or n-hexatriacontane (C36), CH3(CH2)34CH3 as the wax component with either n-heptane or toluene as the solvent component. For all wax-solvent combinations, t...

The advancement of positron emission tomography (PET) depends on the development of new radiotracers that will complement (18)F-FDG. Copper-64 ((64)Cu) is a promising PET radionuclide, particularly for antibody-targeted imaging, but the high in vivo lability of conventional chelates has limited its clinical application. The objective of this work was to evaluate the novel chelating agent SarAr ...

In fermented beverages, yeasts have been exploited for many years and are well-known as alcohol producers. Indonesian traditional however, information about microbiology potential bioactive-compounds of rice wine produced by the local people, especially in Lombok, limited. The present study described compounds including yeast species its that biological activity. was isolated using three growth...

Allium chinense, a main source of “Xiebai” drug in Chinese traditional medicine and commonly known as Ganoderma lucidum belongs to the family Amaryllidaceae. The focus this research was quantify secondary metabolites, antioxidant potential study GC- MS based metabolite profile different solvent leaf extracts A. chinense. reports on bioactive compounds chinense leaves are still insufficient comp...

Saturated hydrocarbons (SHC) of five cruciferous host plants viz., cabbage, cauliflower, broccoli, knol khol and Brussels sprout and the larvae of diamondback moth (DBM), Plutella xylostella reared on these host plants were identified through gas-chromatography. The hydrocarbon profile of host plants and larval body extract of DBM reared on respective host plants revealed a wide variation in qu...
