At an optimal short to long-chain alkyl ammonium ratio of 4 : 6, the growth of CH3NH3PbBr3nanoplatelets can be selectively suppressed with Pb(C17H33COO)2as the sole lead source, enhancing the PLQY of the produced CH3NH3PbBr3nanocrystals.

Trends in global fish catches are described together with fish landlings and fish consumption in the UK. The importance of n–6 and n–3 polyunsaturated fatty acids as essential constituents of human diets is considered and the role of oily fish as a dietary source of the long-chain n–3 polyunsaturates, docosahexaenoic acid and eicosapentaenoic acid, is emphasized. The origin ofn–3 polyunsaturates in the marine phytoplankton and their transmission via zooplankton to fish is described as a means of understanding the consumption of different fish body oils. The ease with which the fatty acid composition of fish body oils can be manipulated by altering the fatty acid composition of their feeds is emphasized and the dietary requirements of marine and freshwater fish for n–3 and n–6 polyunsaturates considered. Farming fish on diets containing principally fish meal and fish oil, as used in salmon production in Scotland, generates a high quality product with levels of long-chain n–3 polyunsaturates equalling or exceeding those of wild fish. Farming fish on high quality marine oils rich in docosahexaenoic and eicosapentaenoic acids is an efficient means of delivering these essential nutrients in human diets and also efficiently exploiting a strictly limited marine bioresource.

Abstract Fatty acids (FA) profiles especially conjugated linoleic acid (CLA) are commonly used to distinguish milk quality. However, its content is very sensitive and tends to change with a different type of feed. The study aims to identify the relationship between the feeding system and milk FA profile in the Pangalengan sub-district. The feeding system and milk FA profiles were studied using two-step post observatory research. Step one, milk was collected from 27 traditional-dairy farms using purposive random sampling and compare with a large-scale farm. The result shows that FA profiles vary greatly among traditional-farms especially for long-chain FA (LCFA) which was found in small concentrations. CLA content was also found higher in traditional-farms. Step two, five traditional-farms with the highest CLA milk content were observed for their feeding systems. Parameter observed including cow’s specification, feed type used, and feed intake. The best ration produced high milk CLA and production was the ration consisted of 38 % high-quality forages and 62 % commercial concentrate. Thus, it can be concluded that milk from traditional farms was better than milk from large-scale farms. The best milk CLA was produced with a combination of 38 % high-quality forages and 62 % commercial concentrate.

A new gemini surfactant containing long chain alkyl ammonium headgroups have been used as corrosion inhinbitor for copper in 3.5% NaCl solution. The weight loss and electrochemical methods results showed that presence of inhibitor greatly decrease corrosion rate, gemini surfactant acted as an excellent corrosion inhibitor with inhibition efficiency greater than 96% at an optimum concentration of 30 mg·L-1. X-ray photoelectron spectroscopy reveals that the gemini surfactant molecules adsorb onto the copper surface through the two ammonium head groups (N+).

The most important nutritional feature of mollusks is their lipid composition. Marine bivalves are a good source of high quality lipid, mainly because they concentrate eicosapentaenoic acid and docosahexaenoic acid. Meanwhile, these n-3 Long Chain Polyunsaturated Fatty Acids (LC-PUFAs) are essential in the fight against inflammation, preventing depression, reducing weight and waist size, decreasing liver fat and promoting mental wellbeing. Typically, marine bivalves have a low saturated fatty acid content and a high n-3 LC-PUFA concentration, which is usually absent in most foods. Freshwater bivalves generally contain lower proportions of n-3 PUFA than marine bivalves; the lipid quality also differ in farmed and wild species. The focus of this review is on physiological important n-3 LC-PUFA present in marine bivalves, with an emphasis on the indicators for assessing quality and the effects of heat on bivalve lipid.
