Biomolecular condensates assemble in living cells through phase separation and related transitions. An underappreciated feature of these dynamic molecular assemblies is that they form interfaces with other cellular structures, including membranes, cytoskeleton, DNA RNA, membraneless compartments. These are expected to give rise capillary forces, but there few ways quantifying harnessing forces cells. Here, we introduce viscoelastic chromatin tethering organization (VECTOR), which uses...
Abstract Flexibility has become increasingly important considering the intermittency of variable renewable energy in low-carbon systems. Electrified transportation exhibits great potential to provide flexibility. This article analyzed and compared flexibility values battery electric vehicles fuel cell for planning operating interdependent electricity hydrogen supply chains while degradation costs.

Abstract Electrochemical and mechanical properties of lithium‐ion battery materials are heavily dependent on their 3D microstructure characteristics. A quantitative understanding the role played by stochastic microstructures is critical for prediction material guiding synthesis processes. Furthermore, tailoring morphology also a viable way achieving optimal electrochemical performances cells.

Abstract Reaction rates at spatially heterogeneous, unstable interfaces are notoriously difficult to quantify, yet essential in engineering many chemical systems, such as batteries 1 and electrocatalysts 2 . Experimental characterizations of materials by operando microscopy produce rich image datasets 3–6 , but data-driven methods learn physics from these images still lacking because the complex coupling reaction kinetics, surface chemistry phase separation 7 Here we show that heterogeneous...
Stabilised Li-rich and Li-poor surface domains formed during fast lithiation delithiation, respectively, cause a large overpotential difference between discharging charging.
Collectives of actively moving particles can spontaneously separate into dilute and dense phases-a fascinating phenomenon known as motility-induced phase separation (MIPS). MIPS is well-studied for randomly with no directional bias. However, many forms active matter exhibit collective chemotaxis, directed motion along a chemical gradient that the constituent generate themselves. Here, using theory simulations, we demonstrate chemotaxis strongly competes MIPS-in some cases, arresting or...
ABSTRACT Large-scale disasters can disproportionately impact different population groups, causing prominent disparity and inequality, especially for the vulnerable marginalized. Here, we investigate resilience of human mobility under disturbance unprecedented ‘720’ Zhengzhou flood in China 2021 using records 1.32 billion mobile phone signaling generated by 4.35 million people. We find that although pluvial floods trigger reductions, overall structural dynamics networks remain relatively...
Mechanistic understanding of phase transformation dynamics during battery charging and discharging is crucial toward rationally improving intercalation electrodes. Most studies focus on constant-current conditions. However, in real operation, such as electric vehicles discharge, the current rarely constant. In this work we study pulsing Li
Using a framework of partial differential equation-constrained optimization, we demonstrate that multiple constitutive relations can be extracted simultaneously from small set images pattern formation. Examples include state-dependent properties in phase-field models, such as the diffusivity, kinetic prefactor, free energy, and direct correlation function, given only general form Cahn-Hilliard equation, Allen-Cahn or dynamical density functional theory (phase-field crystal model)....

The positioning of lithium battery tabs in electric vehicles is a crucial aspect the power assembly process. During pre-tightening process stack assembly, cells and foams undergo different deformations, leading to varying displacements at levels. Consequently, determining tab positions poses numerous challenges during assembly. To address these challenges, this paper proposes method for detecting feature points calculating displacement based on MicKey method. This research focuses cell tab,...
