Abstract Temporal control of the chemical properties a molecular system is main goal research focused on dissipative systems, systems chemistry, and smart materials. In this work, we show that nitroacetic acid, typical activated carboxylic acid (ACA), can be exploited to transiently amplify electrical conductivity an aqueous solution. The addition water solution induces transient increase in conductivity, which then decreases over time following kinetically first order conversion into nitromethane. rate decrease modulated by varying temperature or concentration auxiliary base further added time‐control build variable resistor integrated simple circuits operate devices.

The de novo construction of a living organism is compelling vision. Despite the astonishing technologies developed to modify cells, building functioning cell "from scratch" has yet be accomplished. pursuit this goal alone has─and will─yield scientific insights affecting fields as diverse biology, biotechnology, medicine, and astrobiology. Multiple approaches have aimed create biochemical systems manifesting common characteristics life, such compartmentalization, metabolism, replication derived features, evolution, responsiveness stimuli, directed movement. Significant achievements in synthesizing each these criteria been made, individually limited combinations. Here, we review efforts, distinguish different approaches, highlight bottlenecks current research. We look ahead at what work remains accomplished propose "roadmap" with key milestones achieve vision cells from molecular parts.

Coupling a photochemical reaction to thermal exchange process can drive the latter nonequilibrium steady state (NESS) under photoirradiation. Typically, systems use separate motifs for photoresponse and equilibrium-related processes. Here, we show that photoswitchable imines fulfill both roles simultaneously, autonomously driving dynamic covalent system into NESS continuous light irradiation.

Design in synthetic biology is typically goal oriented, aiming to repurpose or optimize existing biological functions, augmenting with new-to-nature capabilities, creating life-like systems from scratch. While the field has seen many advances, bottlenecks complexity of built are emerging and designs that function lab often fail when used real-world contexts. Here, we propose an open-ended approach design, novelty designed being at least as important how well it fulfils its goal. Rather than solely focusing on optimization toward a single best designing mind may allow us move beyond diminishing returns see performance for most engineered biology. Research artificial life community demonstrated embracing can automatically generate innovative unexpected solutions challenging problems local optima.

Covalent polymers are versatile macromolecules that have found widespread use in society. Contemporary methods of polymerization made it possible to construct sequence polymers, including block copolymers, with high precision. Such copolymers assemble solution when the blocks differing solubilities. This produces nano- and microparticles various shapes sizes. While is straightforward draw an analogy between such amphiphilic phospholipids, these two classes molecules show quite different assembly characteristics. In particular, often under kinetic control, thus producing nonequilibrium structures. leads a rich variety behaviors being observed copolymer assembly, as pathway dependence (e.g., thermal history), nonergodicity responsiveness.
