In a system of cities, smaller cities can exhibit characteristics of large cities even if they do not have the size themselves. This means that there is a disconnection between the size of a city and its characteristics. Cities can borrow or host characteristics that are not on proportion to their size.

Direct Growth of 2D Bilayers on Au(111) for Low‐Coercive Sliding Ferroelectricity
Advanced Materials, EarlyView.Controlled CVD growth of stacking‐defined bilayer ReS2 on Au(111) enables parallel‐stacked bilayers with intrinsic sliding ferroelectricity, a strong piezoelectric response, and an ultralow coercive voltage. Atomic‐resolution imaging and in situ measurements further reveal the decisive role of clean interfaces in achieving low‐barrier ferroelectric ...

Confinement‐Induced Donnan Potential Enables Sealed Hydrovoltaic Power From Microliter Water
Advanced Materials, EarlyView.An ultrathin MXene/cellulose nanofiber (CNF) nanochannel‐based hydrovoltaic generator produces sustained direct current (DC) from a single microliter droplet under sealed operation. Asymmetric nanochannel confinement establishes a persistent ion gradient and a confinement‐induced Donnan potential, harvesting the interfacial free energy released upon ...

Interfacial Failure and Self‐Healing in Solid‐State Batteries
Advanced Materials, EarlyView.Dynamic interfacial self‐healing offers an adaptive route to mitigate coupled mechanical, chemical, and electrochemical degradation in solid‐state batteries. This review connects evolving interfacial failure mechanisms with physical‐flow, chemical‐restoration, stimuli‐responsive, and electric‐field‐assisted repair strategies, highlighting targeted self‐
