Determining the potential bioavailability of heavy metals, evaluating according to adapted regulations is essential to efficiently conserve our coastal and estuarine waters. In this study, it is aimed to determine the industrial pollution and various othe... see more

Extractive tests for determining the plant-availability of soil phosphorus (P) give varying results due to the inherently different characteristics of the extraction solution. Generally, classical soil P tests such as the Olsen or calcium acetate/lactate ... see more

This research aimed to synthesis and apply of bacterial cellulose-diethylenetriamine as a binding layer on the diffusive gradients in thin films method for preconcentration of labile metal Pb and Cd in aquatic systems and sediment of Palu Bay. The results... see more

Tanah adalah sumber alami yang penting dan merupakan bagian dari lingkungan. Merkurimerupakan salah satu logam yang memiliki dampak toksisitas yang berbahaya bagi manusia. Metode untuk ekstraksi bertahap untuk merkuri pada tanah. Merkuri dipisahkan menjad... see more

Abstract:This research is an experimental study that aims to support the temperature and variation of doping in making thin films. The temperature variations at room temperature annealing, 50, 100, 150, and 200oC, and doping variations of 0, 5, 10, 15, 20... see more

Since the discovery of thin films, it has been known that higher crystallinity demands higher temperatures, making the process inadequate for energy-efficient and environmentally friendly methods of thin film fabrication. We resolved this problem by spark... see more

Undoped and aluminum-doped zinc oxide (AZO) thin films are prepared by the sol-gel process. Zinc acetate dihydrate, ethanol, and monoethanolamine are used as precursor, solvent, and stabilizer, respectively. In the case of AZO, aluminum nitrate nonahydrat... see more

Photocatalytic antibacterial sol-gel coated substrates have been reported to kill bacteria under light or in the dark. These coatings showed non-uniform distribution, poor adhesion to the substrate and short effective lifetime as antibacterial surfaces. T... see more

This researh aims to application of cellulose-diethylenetriamine as a binding layer on the diffusive gradients in thin films method with modification of cellulose with diethylenetriamine. The method of diffusive gradients in thin films in principle uses&n... see more
