Microbial Corrosion

Microbial Corrosion

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...

iChip

iChip

The cultivation of environmental microorganisms has long been hindered by the inability to replicate complex native conditions in vitro. The isolation chip (iChip) addresses this limitation by facilitating the growth of previously uncultivable microorganisms through in situ incubation. Designed for high-throughput microbial cultivation, the iChip comprises hundreds of microchambers, each capable of housing a single microbial cell. These microchambers are loaded with a mixture of molten agar and...

Background:

RNA nanotechnology enables design of higher-order RNA structures for applications like drug delivery.
Robustness and stability of designed RNA nanostructures in various molecular contexts require further investigation.

Purpose of the Study:

To investigate the sensitivity of RNA nanostructure self-assembly to environmental conditions.
To characterize the thermodynamic stability of RNA nanostructures.

Main Methods:

Second-order right-angle light scattering was used to analyze RNA nanostructure formation.
Investigated the impact of salt concentration and annealing times on structure stability.

Main Results:

RNA nanostructure self-assembly is highly sensitive to environmental factors like salt conditions and annealing times.
Tertiary contacts crucial for self-assembly require magnesium and melt at 43 °C, significantly lower than secondary structure melting at 75 °C.

Conclusions:

Quantitative and thermodynamic characterization of self-assembling RNA nanostructures is crucial.
Environmental sensitivity impacts the reliability of RNA nanostructures in engineering and therapeutic applications.
