Summary: The fabrication of advanced membranes with simultaneously high electron and proton conductivities has been achieved through the thermal reduction and vertical confinement of graphene oxide (GO) channels. The improvement in electron conductivity is due to the removal of oxygen functional groups, while the extremely reduced channel size allows for selective proton transport and improved proton selectivity.

Summary: The molecular mobility of acetonitrile intercalated into graphite oxide was investigated using the spin probe technique. Two types of intercalated substances, liquid-like and solid-like, were found to coexist between the oxidized graphene layers, with their ratio dependent on temperature. The micro-viscosity of liquid-like intercalated acetonitrile was higher than that of bulk acetonitrile and varied with the amount of intercalated liquid.

Summary: We propose a water pump that transports water molecules through nanochannels by utilizing spatially asymmetric thermal fluctuations. The pump achieves unidirectional water flow without osmotic pressure by exploiting hysteresis in the cyclic transition between wetting and drying states. Our study demonstrates that various types of fluctuations, including white, Brownian, and pink noises, affect the water transport process. The proposed pump operates through fast switching of open and close states to inhibit channel wetting in the presence of white noise, while pink and Brownian noises generate high-pass filtered net flow.

Summary: By using hybrid lattice-Boltzmann molecular dynamics simulations, the flow-driven translocation of comb-like copolymer micelles through a nanochannel is investigated and compared with micelles formed by the corresponding diblock copolymers. The results show that the critical flow flux of micelles formed by the comb-like copolymers is higher than that of micelles formed by the corresponding diblock copolymers, especially with increasing side chain lengths or grafting densities. This research provides a theoretical basis for designing self-assembling micelles for various applications.

Summary: The study presents a strategy to efficiently identify and isolate chiral drugs using a nanochannel and a chiral sensor based on the host-guest system of pillar[5]arene and phenethylamine. The introduced chiral guest R-phenethylamine induces the chirality of the system and amplifies the chiral selectivity for ibuprofen enantiomers. This research provides insights for fabricating highly enantioselective nanosensors for chiral drugs.

Summary: The exceptional ion release and storage ability of biological ion channels have attracted significant attention for various life activities. This study presented the ion transport behavior in a vertically-oriented three-sectional Ti3C2Tx membrane with asymmetric charge distribution. By grafting silane molecules onto the surface, the surface charge polarity of the Ti3C2Tx nanosheet was changed, leading to a diode-like ion transport property in the heterogenous membrane. Numerical simulations based on PNP equations showed that the directional ion diffusion was attributed to ion accumulation and depletion in the nanochannels under different potential biases. The heterogenous membrane also showed potential in desalination and ion storage applications.

Summary: AQPs are small transmembrane tetrameric proteins that facilitate water, solute and gas exchange. Their ability to modulate water membrane permeability in response to specific regulators has been experimentally demonstrated. Studies have shown that the repositioning of conserved residues contributes to restricting water permeation in the channel.

Summary: Peroxisomes are vital organelles in cells, and their malfunction can lead to fatal human diseases. Recent research shows that peroxisomal protein import is similar to nuclear transport, with a YG domain in the peroxisomal membrane protein PEX13 forming a meshwork that acts as a water conduit for delivering folded proteins into peroxisomes.

Summary: Clean energy is urgently needed as a solution to the depletion of fossil fuel resources and increasing carbon emissions. The study investigates the flow-induced vibration and energy harvesting performance of a cylinder with attached fins. Four different configurations were tested and compared, and a bi-directional flow-energy harvester was implemented by attaching both windward and leeward fins to the cylinder. The results showed that this harvester achieved higher vibration amplitudes and had a broader velocity range compared to a plain cylinder.
