Lauric acid (LA) and myristic acid (MA) were used to prepare a binary eutectic mixture. The expanded graphite (EG) was used as the carrier, and the lauric–myristic acid/expanded graphite (LA–MA/EG) composite phase change material was prepared by physical adsorption method. The microstructure, chemical structure, and thermal properties of LA–MA/EG were characterized by scanning electron microscopy (SEM), differential scanning calorimeter (DSC), Fourier transform infrared spectroscopy (FTIR), and thermal conductivity measurement.

Used cooking oil, a byproduct of household cooking oil waste, has the potential to be turned into energy. However, its utilization is not yet optimal, and it often just becomes household waste. Therefore, in this study, used cooking oil is used to produce biofuel. The CoMo/Bottom ash catalyst is used to accelerate the biofuel production process.

Abstract p53 is the most extensively studied tumor suppressor. It serves as a major barrier against malignant transformation and the p53 pathway is inactivated in almost all human tumors. A large percentage of tumors inactivate p53 by point mutations in the DNA binding domain (DBD) of the protein. Most mutations destabilize p53 protein folding, causing its partial denaturation at physiological temperature. Thus a high proportion of human tumors overexpress a potential potent tumor suppressor in a non-functional, improperly folded form. Previously, we reported the use of phage display technolog

Free fatty acids possess antimicrobial properties in the natural defense system of many eukaryotes. In this study, we synthesized nanoformulations of myristic acid for antimicrobial activity. The myristic acid nanoformulations (MN) were unstable due to crystallization. This problem was overcome by the addition of the liquid fatty acids and by using two surfactants of hydrophilic and lipophilic nature. MN exhibited a small size (100 nm), and their physical form was affected by the amount of the liquid fatty acid. MN with myristic acid and liquid fatty acid in 1:1 formed solid NLC and 2:3 formed

Abstract One of the solutions to energy problems is the reuse of waste heat. One way to reuse waste heat is to use latent heat storage materials. Erythritol, of which melting point is the temperature range between 100 and 200°C, has attracted much attention as latent heat storage materials. However, as usual erythritol shows the large supercooling, its supercooling degree must be decreased to use for latent heat storage material. To achieve this, we have investigated the mixed erythritol with fatty acids as addition agents. Samples were prepared by physically mixing of erythritol and fatty aci

The bioluminescent marine bacterium, Vibrio harveyi, can utilize exogenous myristic acid (14:0) for β-oxidation, phospholipid and lipid A synthesis, and as an source of myristyl aldehyde for light emission in the V. harveyi dark mutant M17. A variety of genetic and biochemical strategies were employed in an attempt to isolate V. harveyi mutants defective in myristate uptake and to characterize proteins involved in this process. Although [3H]myristate uptake in a tritium suicide experiment decreased the survival of nitrosoguanidine-treated M17 cells by a factor of 105, none of the surviving cel

Breeding of goats and sheep for milk production shows positive dynamics in Russia. For effective breeding it is necessary to collect information on the composition of goat and sheep milk and the nature of correlations between its components in different breeds. The article compares infrared spectra of milk parameters of Alpine and Zaanen goats, Lacon and Ostfriesian sheep breeds, obtained on the automatic analyzer CombiFoss 7 D. It was found that in the milk of Alpine goats the content of the mass fraction of fat, solids, palmitic, long-, medium-, monounsaturated and saturated fatty acids was

ATP-binding cassette (ABC) transporters are conserved in all kingdoms of life, where they transport substrates against a concentration gradient across membranes. Some ABC transporters are known to cause multidrug resistances in humans and are able to transport chemotherapeutics across cellular membranes. Similarly, BmrA, the ABC transporter of Bacillus subtilis, is involved in excretion of certain antibiotics out of bacterial cells. Screening of extract libraries isolated from fungi revealed that the C14 fatty acid myristic acid has an inhibitory effect on the BmrA ATPase as well as the transp

In the oil and gas industry, wax formation and deposition are common problems, particularly during production and transportation. To better understand the expected behaviour of a given waxy crude oil and consequently select the best solution to prevent wax deposition, it is vital to conduct laboratory tests or numerical simulations to model its performance. For a Brazilian oil field, the phase behaviour of 17 crude oils was modelled using Multiflash software. To tune the model, laboratory tests were used, including true boiling point curves and viscosity tests. This study followed two stages:
