Investigation Into the Role of Reductants and Cosubstrates in Lytic Polysaccharide Monooxygenase Thermothielavioides terrestris AA9E Binding to Cellulose by Single‐Molecule Imaging

Biotechnology and Bioengineering, EarlyView.
In glucose oxidase + catalase (GODCAT) and protocatechuic acid/protocatechuate 3,4‐dioxygenase (PCA/PCD) oxygen‐scavenging buffers, some Cy5‐TtAA9E bound to crystalline cellulose fibrils. Adding ascorbic acid (AscA) vastly increased enzyme binding to cellulose in the GODCAT buffer but diminished enzyme binding to cellulose in the PCA/PCD buffer ...

The need for advancing algal bloom forecasting using remote sensing and modeling: Progress and future directions

Ecological Indicators
Algal blooms are often major drivers of environmental and economic challenges. As these blooms increase in frequency and size, there is an increasing need for forecasting models to accurately predict their occurrence and progression.

Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

Chemistry &Biodiversity, EarlyView.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.

Effect of pH on the Electrochemical Reduction of Nitrate on Metallic Copper

ChemCatChem, EarlyView.
The electrochemical reduction of nitrate on Cu was investigated between pH 4.4–9.3 using on line DEMS and in situ FTIR. We show that electrolyte pH governs the stabilization and conversion of key intermediates such as NO, N2O, and N2H4, and alters local interfacial conditions.

Whitings in the Red Sea

The Depositional Record, EarlyView.
We present the first documentation of whitings in the Red Sea, observed in a lagoonal environment. These events are linked to cascading offshore dense waters that liberate trapped sea floor nutrients, triggering algal blooms and elevating alkalinity, which is buffered by direct CaCO3 precipitation—contributing to the accumulation of aragonite mud in ...

Design Optimization of Surface Seawater Intake Piping for Hybrid Ocean Thermal Energy Conversion Pilot Plant

Energy Science &Engineering, EarlyView.
ABSTRACT Hybrid Ocean Thermal Energy Conversion (H‐OTEC) systems are characterized by the adoption of both open‐loop and closed‐loop Rankine cycles. In the closed‐loop configuration, a working fluid such as ammonia is evaporated in a heat exchanger, utilizing the heat from water vapor generated in a vacuum chamber by warm surface seawater introduction.
