ConspectusThe success of living systems lies in using mild conditions to construct diverse structures by reducing energy barriers that need be overcome. However, the most powerful processing methods developed humans, such as integrated die casting and additive manufacturing, are either energy-consuming or time-consuming. Hence, it is very attractive environmentally friendly use simple, prebuilt, programmable components transform them into with various functions methods. Dynamic covalent bonds, which can entire structure breaking a few low-energy bonds material, reduce required input dissipated when constructing ordered structures, making an important tool for developing materials conditions.The challenges this field lie improving accessibility, efficiency, batch-processing capability. The establishment order relies critically on selective dissipation. In context, "order" refers thermodynamic state deviates from equilibrium, exemplified temperature gradient specific spatial distribution particles, simultaneously increases systemic reduces entropy. To forge dissipation must rather than uniform. selectivity necessitates patterned inputs stimuli, digital light processing, templating, inherently customized thus not readily scalable mass industrial production. Consequently, pivotal solution minimizing reliance stimuli. For example, accessibility scalability flood illumination superior processing. Concurrently, usage we increase rate between multiple together essential aspect efficiency.This Account summarizes how our research group uses dissipative characteristics selenium information density achieve two-dimensional plane three-dimensional space. process, propose series unique strategies programming, interfacial, unconstrained, modular These improve ultimately time programming nonpatterned stimuli within minutes. Moreover, also look forward perspective chemical design illustrate its derived dynamic accelerate dissipation, difference nondissipation areas, further seconds.

Volumetric printing, an emerging additive manufacturing technique, builds objects with enhanced printing speed and surface quality by forgoing the stepwise ink-renewal step. Existing volumetric techniques almost exclusively rely on light energy to trigger photopolymerization in transparent inks, limiting material choices build sizes. We report a self-enhancing sonicated ink (or sono-ink) design corresponding focused-ultrasound writing technique for deep-penetration acoustic (DAVP). used experiments modeling study frequency scanning rate-dependent behaviors. DAVP achieves key features of low streaming, rapid sonothermal polymerization, large depth, enabling hydrogels nanocomposites various shapes regardless their optical properties. also allows at centimeter depths through biological tissues, paving way toward minimally invasive medicine.

The technology of native chemical ligation and postligation desulfurization has greatly expanded the scope modern protein synthesis. Here, we report that ultrasonic energy can trigger robust clean desulfurization, developed an ultrasound-induced (USID) strategy is simple to use generally applicable peptides proteins. USID involves a cleaning bath easy-to-use easy-to-remove sonosensitizer, titanium dioxide. It features mild convenient reaction conditions excellent functional group compatibility, e.g., with thiazolidine (Thz) serotonin, which are sensitive other strategies. robust: without reoptimizing conditions, same procedure be used for broad range proteins one or more sulfhydryl groups, even in multi-hundred-milligram scale reactions. utility was demonstrated by one-pot synthesis bioactive cyclopeptides such as Cycloleonuripeptide E Segetalin F, well convergent functionally important histone H3.5 using Thz temporary protecting group. A mechanistic investigation indicated proceeds via radical-based mechanism promoted low-frequency low-intensity ultrasonication. Overall, our work introduces mechanically triggered approach potential become method general both academic industrial laboratories.
