Reconstructed Polyamide Nanolayers via Two‐Stage Interfacial Polymerization Engineering for Precise Ion Sieving

Advanced Science
Efficient lithium extraction from brines remains challenging due to the comparable hydrated radii of Li+ and Mg2+ and the extreme ionic strength of the feed solutions. In this work, a reconstructed polyamide (PA) nanofiltration membrane was developed via

Kinetic selectivity in metal-organic framework chemical sensors

Nature Communications
Selective detection of specific volatile organic compounds (VOCs) is crucial for health, safety, and environmental applications, but current sensors suffer from poor selectivity and struggle to measure specific VOCs in the presence of interfering ...

Techno-economic process optimization for a range of membrane performances: What provides real value for point-source carbon capture?

Carbon Capture Science & Technology
Membranes provide a unique opportunity for heavy industry decarbonization and a real solution requires optimal system design. We use a superstructure process model to minimize capital and operational expenses for post-combustion carbon capture systems ...

New Channelrhodopsin with a Red-Shifted Spectrum and Rapid Kinetics from Mesostigma viride

mBio, 2011
Light control of motility behavior (phototaxis and photophobic responses) in green flagellate algae is mediated by sensory rhodopsins homologous to phototaxis receptors and light-driven ion transporters in prokaryotic organisms. In the phototaxis process,

Dual mitotic bookmarking by GAF and H3K27ac orchestrates differential propagation of cell fate memory in neural development

Nature Communications
In brain development, neural stem cells (NSCs) undergo asymmetric cell divisions to replicate themselves and meanwhile produce differentiating siblings. It remains obscure how NSCs preserve their self-renewing fate across mitosis.

Computing with Membranes

Journal of Computer and System Sciences, 2000
New models of massive parallel computation devices are suggested. The basic idea of these devices is the modelling of the evolution of a family of cells. It is a modification of DNA-computers or neural networks or abstract chemistry machines. Three versions of the device are defined, the first one computes subsets of natural numbers, the second (or ...
