Electrocatalytic CN Coupling: Advances in Urea Synthesis and Opportunities for Alternative Products

ChemSusChem, EarlyView.
This review explores electrocatalytic urea synthesis via carbon–nitrogen (CN) coupling from CO2 and nitrogen species, specifically nitrate, nitrite, nitric oxide, and nitrogen gas. It discusses recent discoveries in catalyst design, reaction pathways, and detection methods. Future outlooks on industrial applications, alternative CN coupling products,

Monitoring studies should consider temporal variability to reveal relations between cyanobacterial abundance and environmental variables

Anais da Academia Brasileira de Ciências, 2015
One of the main goals of monitoring cyanobacteria blooms in aquatic environments is to reveal the relationship between cyanobacterial abundance and environmental variables. Studies typically correlate data that were simultaneously sampled.

Genomic profiles of four novel cyanobacteria MAGs from Lake Vanda, Antarctica: insights into photosynthesis, cold tolerance, and the circadian clock

Frontiers in Microbiology
Cyanobacteria in polar environments face environmental challenges, including cold temperatures and extreme light seasonality with small diurnal variation, which has implications for polar circadian clocks.

Total Synthesis of Ectocarpin A

European Journal of Organic Chemistry, EarlyView.
A fully enantioselective total synthesis of ectocarpin A, a new oxylipin, has been achieved in 12 steps starting from tetrahydro‐1H‐cyclopentafuranone. Key steps include the formation of the chiral core, diastereoselective epoxidation, enzymatic desymmetrization of a 1,4‐diol, epimerization, and strategic Wittig and Julia‐Kocienski olefinations to ...

Deciphering the Potential Causal and Prognostic Relationships Between Gut Microbiota and Brain Tumors: Insights from Genetics Analysis and Machine Learning

Exploration, EarlyView.
The causal relationship between gut microbiota and brain tumors and potential prognostic value of microbiota are still unclear. This study confirmed the causal effects of specific gut microbiota on three common brain tumors and identified microbe‐related genes that are expressed in brain tissue and correlated with the abundance of gut microbiota ...

Exploring Components of the CO2-Concentrating Mechanism in Alkaliphilic Cyanobacteria Through Genome-Based Analysis

Computational and Structural Biotechnology Journal, 2017
In cyanobacteria, the CO2-concentrating mechanism (CCM) is a vital biological process that provides effective photosynthetic CO2 fixation by elevating the CO2 level near the active site of Rubisco.

Transition of cavitating flow to supercavitation within Venturi nozzle – hysteresis investigation

EPJ Web of Conferences, 2017
Cavitation is usually considered as undesirable phenomena. On the other hand, it can be utilized in many applications. One of the technical applications is using cavitation in water treatment, where hydrodynamic cavitation seems to be effective way how ...
