Artificial Cells Have Domains, But No Membranes

Jawbreaker Rainbow image

Artificial cells are synthetic agents that mimic live cells, useful as biological models or technological platforms for healthcare and bioprocessing. Like their living counterparts, artificial cells often feature internal compartments separated by membranes, which are necessary to sustain cell-like functionalities. …

Metalworking operations involve many interacting factors, only one of which is the metalworking fluid (MWF). Solving problems on the production floor requires identifying the factor (or factors) most responsible for the problem. Besides the MWF formulation, other contributors to machining performance include maintenance practices, the type of metalworking operation, machining variables (speed, feed, etc.), the workpiece metallurgy and the environment in the production area.

Nitrate Reduction Provides Insights into Evolving Electrode Structures

Nitrate Reduction Provides Insights into Evolving Electrode Structures

Wastewater treatments that reduce nitrate to form ammonia not only remove nitrate pollutants, but the resulting ammonia can be used in a variety of industrially useful reactions. William Tarpeh and colleagues recently studied the interacting effects of electrochemical nitrate reduction and the evolving structure and …

New Superatom Is Both Stable and Magnetic

New Superatom Is Both Stable and Magnetic

Superatoms are small symmetric clusters of atoms with electronic states bunched together into closely packed shells. Like their individual-atom counterparts, superatoms with filled shells have the greatest electronic stability. Typical stable octahedral transition metal chalcogenide clusters have a single set of filled electron shells and …

Sulfur-containing organic molecules called thiols and thiocatechols are used in a variety of reactions involving the formation of disulfide bonds, coupling to double and triple bonds, and attachments to metal surfaces. In contrast, their polymer counterparts, thiophenol-pendant and dithiocatechol-pendant polymers, tend to oxidize and form …

Bacteria Become Tiny Catalytic Synthesis Vessels

Artificial metalloenzymes, made from protein scaffolds incorporating synthetic metal complexes, combine the versatility of transition-metal catalysts with the shape selectivity of enzymes. Until now, getting the metal complex into the cell has been difficult, and the reactivity of artificial enzymes in living cells has been …

Organic catalyst goes against flow
Image by Gerd Altmann/Pixabay

Making more stable compounds out of less stable ones is nothing new, but going the other direction often requires multiple synthesis steps, harsh reaction conditions, and separating the desired products from the inevitable byproducts. Alison Wendlandt and co-workers have found a way around this obstacle, …
