The oxygen content of graphene oxide (GO) is directly related to its physical and chemical properties, such as hydrophilicity, suspension stability, adsorption, ion-sieving ability GO membranes.
Under ambient conditions, the only known valence state of calcium ions is +2, and corresponding crystals with are insulating nonferromagnetic. Here, using cryo-electron microscopy, we report direct observation two-dimensional (2D) CaCl on reduced graphene oxide (rGO) membranes, in which monovalent (i.e. +1). Remarkably, metallic rather than properties displayed by those crystals. More interestingly, room-temperature ferromagnetism, graphene-CaCl heterojunction, coexistence...
The two-dimensional (2D) "sandwich" structure composed of a cation plane located between two anion planes, such as anion-rich CrI3, VS2, VSe2, and MnSe2, possesses exotic magnetic electronic structural properties is expected to be typical base for next-generation microelectronic, magnetic, spintronic devices. However, only few 2D materials have been experimentally discovered fabricated, they are vastly limited by their conventional stoichiometric ratios stability under ambient conditions....

Herein, a bioinspired membrane featuring intelligent adaptive 2D nanochannels outstanding molecule is reported. In particular, protein‐mimetic nanochannel pH‐responsive characteristics constructed by introducing sodium alginate (SA) molecular chains into GO laminates. The conformational transformation of SA under varying pH conditions enables...
A simple way to fabricate pure rGO membranes shows ultrahigh water permeance and excellent multivalent metal ion rejection, as well long-term stability.
The application of graphene oxide (GO)-based membranes combined with a quartz crystal microbalance (QCM) as humidity sensor has attracted great interest over the past few years. Understanding influence structure GO membrane (GOM) on adsorption/desorption water molecules and transport mechanism in is crucial for development applications using GOM-based sensors. In this paper, by investigating effects oxygen-containing groups, flake size interlayer spacing performance sensing, it was found...

Recently, the graphene, β‐CuI is observed experimentally Here, it shown that this β‐CuI@graphene possesses unexpected piezoresistive effect room‐temperature ferromagnetism. Moreover, crystal likely be...
Cross-linking with large flexible molecules is a common method to improve the stability and control interlayer spacing of graphene oxide (GO) membranes, but it still suffers from limitation low water flux. Herein, novel high flux GO membrane was fabricated using pressure-assisted filtration method, which involved synergistic chemical cross-linking divalent magnesium ions 1,6-hexanediamine (HDA) on polyethersulfone (PES) support. The cross-linked HDA (GOHDA-Mg2+ ) exhibited up 144 L m-2 h-1...
Lithium plays an increasingly important role in scientific and industrial processes, it is extremely to extract lithium from a high Mg 2+ /Li + mass ratio brine or recover the leachate of spent lithium-ion batteries. Conventional wisdom shows that Li with low valence states has much weaker adsorption (and absorption energy) graphene than multivalent ions such as . Here, we show selective thermally reduced oxide (rGO) membranes over other metal , Co Mn Ni Fe Interestingly, strength reaches up...
The discovery of specific matter phases with abnormal physical properties in low-dimensional systems and/or on particular substrates, such as the hexagonal phase ice and two-dimensional (2D) CaCl an valence state, continuously reveals more fundamental mechanisms nature. Alkali halides, represented by NaCl, are one most common compounds usually thought to be well-understood. In past decades, many theoretical studies suggested existence phase, that is, graphitic-like alkali halides at high...
Abnormal salt crystals with unconventional stoichiometries, such as Na2 Cl, Na3 K2 and CaCl that have been explored in reduced graphene oxide membranes (rGOMs) or diamond anvil cells, hold great promise applications due to their unique electronic, magnetic, optical properties predicted theory. However, the low content of these crystals, only <1% rGOM, limits research interest utility applications. Here, a high-yield synthesis 2D abnormal stoichiometries is reported, which achieved by...
Monolayer of graphene oxide has great potential applications in ion and molecular screening, desalination purification water, gas separation, biosensing, proton conductors, lithium batteries, super capacitors other fields, due to its excellent physical chemical properties. However, the prepared by methods, such as commonly used Hummers method is a metastable material. The transformation regulation properties final morphology are essential, systematic research urgently needed. In this paper,...
Ferromagnetism, as one of the most valuable properties materials, has attracted sustained and widespread interest in basic applied research from ancient compasses to modern electronic devices. Traditionally, intrinsic ferromagnetism been attributed permanent magnetic moment induced by partially filled d- or f-orbitals. However, development ferromagnetic materials limited this structure convention. Thus, identification additional that are not constrained conventional rule but also exhibit is...
The expanding applications call for novel new-generation wide-bandgap semiconductors. Here, we show that a compound only composed of the ordinary elements Na and Cl, namely three-dimensional NaCl2 crystal, is semiconductor. This finding benefits from breaking conventional stoichiometry frameworks in theoretical design, leading to discovery XY2 (X = Na, Li, K; Y F, Br, I) crystals, with covalent bonds pairs inducing wide bandgap 2.24 4.45 eV. Crucially, such an unexpected crystal was...

Here, inspired by cell membrane potential living species, we demonstrate two-dimensional nanofluidic gradient structure (TNGS) integrating series graphene oxide (GO) reduced GO (rGO) order size interlayer spacing along horizontal direction. Through asymmetric...
At ambient conditions, potassium dihydrogen phosphate (KDP) usually exists in tetragonal structure, and only transforms to monoclinic structure at a temperature around 503 K. In this study, stable KDP is developed room using mixture of graphene oxides unsaturated solution. Furthermore, reversible phase transition between observed by tuning the distance oxide layers. The first-principles calculation suggests that more energetically favorable when sandwiched two graphitic surfaces with large...
