“…Reducing the size of the channel is key to achieving a molecular superfluid. 1,2 Although the inner diameter of the biological water channel is only ~0.4 nm, it allows an ultrahigh water flux of ~10 9 s -1 at body temperature. 19,20 Thus, it is believed that an ordered water flow must exist in the channel, which allows ultrafast transport of water molecules in a superfluidic manner (Fig.…”

“…As the pore size reduced, it became thermodynamically favorable for the molecule to condense to an ordered phase. 2 The magnitude of the thermal response signal reflects the total heat of adsorption. 47 When the surface areas of mesoporous CMK-3 and microporous TiC-CDC-600 become comparable, more latent heat of phase change is released during the adsorption of n-butane in the microporous sample, indicating the high binding enthalpy for small pores.…”

“…1 Because ultrafast transport has a high flux and consumes low energy, the molecular/ionic superfluid is highly important in chemical reactions and transmission of bioinformation. 2,3 QSF reactions make the reactant molecules orderly in a nanochannel to satisfy symmetrymatching principles, and hence, these reactions can afford high flux and 100% selectivity with low reaction activation energy. 4,5 Biophoton-driven DNA replication can be carried out via yield oscillations modulated by gold nanoparticle distance.…”

Ordered-and high-flux flow of molecules and ions in biological channels is considered as quantum-confined superfluid, which is highly important in chemical reaction and bioinformation transmission. However, the driving forces for these ordered arrangements of molecules and ions in the confined space have not been discussed.Here, we demonstrate that the driving force of molecular/ionic superfluid formation is the attraction-repulsion balance of particles under the effect of interfacial confinement, as well as the space-confinement effect enough to reduce the degrees of freedom of the particles and then greatly limit the disorder of their movement. The competition of attractive potential energy (E) with the disorder caused by thermal noise (k B T) results in the phase transition temperature. When |E| > k B T, an ordered structure of the particles can be formed. A superfluid of 4 He atoms is formed below 2.17 K. Molecules or ions can achieve a superfluid at a higher phase transition temperature (near body temperature) under a certain confined distance, e.g., about twice van der Waals equilibrium distance (2d 0 ) for molecules and twice Debye length (2λ D ) for ions and ion-molecules. Owning to the unique characteristic of ultralow resistance for particles transport, molecular/ionic superfluid will have a significant impact in areas such as energy transfer, storage and conversion.

“…[1][2][3][4][5][6][7][8][9][10] Although several strategies, including chemical modification, hetero-wettability fabrication, and temperature differences, have been proposed to induce directional liquid motion, the liquid motion is usually limited to the gradient on the surface and easily influenced by the extra energy including vibrations and heat.

Liquid unidirectional spreading without energy input has attracted worldwide attentions owing to its potential applications in various fields. The liquid transfer between the adjacent microcavities on the peristome of Nepenthes alata provides great inspiration in that the concave curvature edge structure has the possibility to induce liquid directional spreading. Herein, the effect of concave curvature edge on liquid spreading is found to be different from that of the solid edge described by the Gibbs inequality condition. In this condition, there exist two liquid transfer states, namely conduction and resistance. Taking the advantages of the concave curvature edge, a new unidirectional liquid spreading channel is designed and fabricated by the traditional machining method, and its liquid directional spreading function is validated. This article provides a theoretical and technical support for the design and fabrication of liquid unidirectional spreading channel without an external energy input.

Interlayer transport of charges and carriers of 2D nanomaterials is a critical parameter that governs the material and device performance in energy storage applications. Inspired by multilevel natural bamboo‐membrane with ultrafast water and electrolyte transport properties to support its super‐rapid growth rate, 2D–2D multilevel heterostructured graphene‐based membranes with tailored gradient interlayer channels are rationally designed for achieving ultrafast interlayer ion transport. The bioinspired heterostructured membranes possess multilevel interlayer spacing distributions, where the closely packed layers with sub‐nanosized interlayer space provide ultrafast confined interlayer ion transport, while the loosely stacked outer layers consisting of open channels with large distances up to few micrometres are favorable for rapid wetting and penetration of liquid electrolytes. The combination of advantages of large‐size open channels and nanosized confined channels offers ultrafast electrolyte wetting and permeation and interlayer ion transport and provide the devices with superior volumetric capacity as free‐standing electrodes for rechargeable batteries.
