The recent discovery of temporally controlled gels opens broad perspectives to the field smart functional materials. However, obtain fully operative systems, design simple and robust displaying complex functions is desirable. Herein, we fuel dissipative gelating materials through iterative additions trichloroacetic acid (TCA). This enables switch over time an acid/base-dependent commercially available amino gelator/DBU combination between three distinct states (anionic, cationic, neutral),...
Abstract Spontaneous chemical reactions proceed energetically downhill to either a local or global minimum, limiting possible transformations those that are exergonic. Endergonic do not spontaneously and require an input of energy. Light has been used drive number deracemizations thermodynamically unfavourable bond-forming reactions, but is restricted substrates can absorb, directly indirectly, energy provided by photons. In contrast, anabolism involves uphill powered fuels. Here we report...
We consider dynamical systems in $\mathbb{R}^d$ driven by a vector field $b(x) = - \nabla a(x)$, where $a$ is double-well potential with some smoothness conditions. show that these when subjected to small random disturbance exhibit metastable behavior the sense defined [2]. More precisely, we prove process of moving averages along path such system converges law properly normalized jump Markov process. The main tool for our analysis theory Freidlin and Wentzell [7].
Smart materials reversibly changing properties in response to a stimuli are promising for broad array of applications. In this article, we report the use trichloroacetic acid (TCA) as fuel create new types time-controlled switching from gel solution (gel-sol-gel cycle). Applying various neutral amines organogelators, TCA addition induces amine protonation, system solution, while decarboxylation over time enables return initial state. Consequently, newly obtained possess interesting...
We report on a head-to-tail dual molecular motor consisting of two (identical) units whose pyrrole-2-carboxylic rings are turned in contra-rotary (i.e., disrotatory) fashion about common phenyl-2,5-dicarboxylic acid stator. The motors directionally rotate via information ratchet mechanisms, which the hydration carbodiimide (fuel) to form urea (waste) is catalyzed through chemomechanical cycle unit, resulting directional rotation biaryl C–N bond. arrangement produces coaxial contra-rotation...
In this paper we study metastability and nucleation for a local version of the two-dimensional lattice gas with Kawasaki dynamics at low temperature density. Let β>0 be inverse let Λ̄⊂Λβ⊂Z2 two finite boxes. Particles perform independent random walks on Λβ\Λ̄ inside Λ̄ feel exclusion as well binding energy U>0 particles neighboring sites, i.e., follows Metropolis algorithm an attractive Hamiltonian. The initial configuration is chosen such that empty, while total ρ|Λβ|...
Dissipative systems are based on the supply of energy to a system by fuel pulses and dissipation this through decomposition, resulting in repetition given physical or biological function. Such out equilibrium processes at heart all living organisms, past decade, researchers have attempted transpose these principles purely synthetic systems. However, upon waste generated tends accumulate system, rapidly inhibiting machinery after few cycles pulses. In order solve issue, trichloroacetic acid...
