The development of catalytic methods for the effective functionalization of methane yet remains a challenge. The best system known to date is the so-called Catalytica Process based on the use of platinum catalysts to convert methane into methyl bisulfate with a TOF rate of 10(-3) s. In this contribution, we report a series of silver complexes containing perfluorinated tris(indazolyl)borate ligands that catalyze the functionalization of methane into ethyl propionate upon reaction with ethyl diazoacetate (EDA) by using supercritical carbon dioxide (scCO2) as the reaction medium. The employment of this reaction medium has also allowed the functionalization of ethane, propane, butane, and isobutane.

The catalytic efficiency of sulfonated polystyrene foam waste (SPS) and sulfonated gamma alumina (SGA) in Friedel-Crafts type reactions was compared. All of the materials were studied using the state-of-the-art characterization techniques. SPS was found to carry a higher load of -SOH functional groups (1.

In this article, the effect of parameters in the solid oxide fuel cell cycle has investigated using the response surface method. The thermodynamic modeling of this cycle has been done by EES software, which by considering three variables (current density, molar flow rate and fuel cell temperature) as input parameters, to examine the mutual effects of parameters on the objective functions (net output power and exergy efficiency) using the experimental design method. According to the results of thermodynamic analysis, the net power output and exergy efficiency of solid oxide fuel cell are 2424 kW, 52.

In soil polluted with benzene, toluene, ethylbenzene, and xylenes (BTEX), oxygen is rapidly depleted by aerobic respiration, creating a redox gradient across the plume. Under anaerobic conditions, BTEX biodegradation is then coupled with fermentation and methanogenesis. This study aimed to characterize this multi-step process, focusing on the interactions and functional roles of key microbial groups involved.

Unlabelled: Many species of proteobacterial methane-consuming bacteria (methanotrophs) form a hauberk-like envelope represented by a surface (S-) layer protein (SLP) matrix. While several proteins were predicted to be associated with the cell surface, the composition and function of the hauberk matrix remained elusive. Here, we report the identification of the genes encoding the hauberk-forming proteins in two gamma-proteobacterial (Type I) methanotrophs, 5GB1 (EQU24_15540) and 20Z (MEALZ_0971 and MEALZ_0972).

A significant proportion of next-generation sequencing (NGS) data ends up not being used since they comprise information out-of-scope of the primary studies. This 'waste' of potential can be harnessed to explore organellar genomes, such as the mitochondrial DNA, and be used for evolutionary, conservation and biodiversity research. We present the complete mitochondrial genomes of the deep-sea methanotrophic sponges and (Demospongiae, Poecilosclerida) retrieved from previously published whole metagenome sequencing data.
