Distortion of the polyhedron can be caused by the degeneracy in the population of atomic or molecular orbitals, which can be removed by the cooperative Jahn–Teller effect. This effect is often accompanied by the formation of low-dimensional magnetic structures, of which we will consider only chain, or quasi-one-dimensional, magnetic compounds variety. Magnetic chains are formed when transition metal polyhedra bond through a vertex, edge, or face. Moreover, the magnetic entities can be coupled through various nonmagnetic units like NO₃, SiO₄, <i>Pn</i>O₃ or <i>Pn</i>O₄, <i>Ch</i>O₃ or <i>Ch</i>O₄, where <i>Pn</i> is the pnictide and <i>Ch</i> is the chalcogen. In most cases, the local environment of the transition metal is represented by oxygen and/or halogens. The prevailing number of chain systems is based on 3<i>d</i> transition metals, albeit 4<i>d</i> and 5<i>d</i> systems attract more and more attention.

Therefore, the sustainable management of atmospheric moisture is crucial for creating a comfortable lifestyle for humanity. Cooling condensation and desiccant drying are established methods for adjusting atmospheric humidity, yet they still face a range of challenges including energy usage, efficiency levels, operational simplicity, and broad applicability.

Its appeal lies in the sustainable and plentiful nature of its raw materials, coupled with its distinctive one-dimensional nanostructure, abundant surface hydroxyl groups, and outstanding mechanical strength. Furthermore, its capacity to readily assemble into diverse structures through straightforward processes makes it a compelling choice for advancing the development of next-generation biopolymer-based hygroscopic materials. Lightweight and self-standing hygroscopic aerogels can be fabricated after integration nanocellulose with various hygroscopic salts through a series of methods. As well as adsorbing atmospheric moisture, they can transform gaseous water into liquid water, and transport it to their interiors for storage. Water evaporation and release are realized by simply exposing the moisture-adsorbed aerogels to sunlight.

They usually play important roles in various physiological and pathological events, showing a close relationship with human health. However, due to the ultralow concentrations of these substances and the presence of interfering chemicals, accurate and reliable measurement of these ions and molecules remains a huge challenge. Nanopore sensors, which combine nanofluidic and electrochemical technologies, have received a great deal of attention in recent years. Nanopore sensing is generally realized by measuring the electrochemical behaviors of ions in nanopores, which endows this technique with the advantages of high sensitivity, fast response, high sampling frequency, and experimental simplicity. In addition, owing to the confinement effect, the interaction between analytes and the nanopore is greatly enhanced, which can further improve the sensing sensitivity, even achieving single-entity analysis. With the development of materials science, micro/nanoprocessing technologies, and mass transport theories at the nanoscale, nanopore sensors have established themselves as a promising tool for the analysis of ions, biomolecules, and nanoparticles. Nanopore materials, as the core of nanopore sensors, can be classified into three categories based on the pore structure: single nanopores, arrayed nanopores, and composite nanopores. Single nanopores include two-dimensional (2D) material based single nanopores and glass/quartz nanopipettes. The single-pore structure can offer high sensitivity and spatial resolution, making single nanopores suitable for single-entity analysis. Arrayed nanopores consist of a large number of orderly arranged pores, generally including polymer nanopores and metal oxide nanopores. Arrayed-nanopore sensors possess advantages, including easy preparation, low cost, and high throughput, making them widely applicable in biochemical and environmental analysis. Composite nanopores, on the other hand, combine nanopores with other materials, such as conductive polymers and plasmonic metals, which can further enhance the sensitivity and accuracy of nanopore sensing. Through introducing recognition elements into these nanopores, the interaction between the analyte and the recognition elements can produce predictable changes in the nanopore properties, such as diameter, pore shape, surface charge, and wettability, resulting in readable changes in ion-current signals.&lt;/p&gt;&lt;p &gt;In this Account, we summarize the recent advancements in nanopore materials, nanopore-sensing mechanisms, and practical nanopore sensing applications, which are mainly based on work published by our group.

Electrocatalytic conversion of an energetic small molecule is an efficient way of energy storage and conversion with clean energy as the carrier.

They include a diverse range of materials, such as graphene, chalcogenide, oxide, hydroxide, and carbide. Such 2D materials can be produced via the delamination of their precursor layered compounds. Different from graphite and van der Waals layered compounds, there are a wide range of layered materials accommodating interlayer counterions, serving as a trigger for delamination upon exchange with suitable species. Since interlayer galleries swell evenly and infinitely, single-layer nanosheets can be obtained in high yield in the form of a colloidal suspension.&lt;/p&gt;&lt;p &gt;The arrangement of unilamellar 2D nanosheets on a substrate surface, avoiding large gaps and overlaps, is crucial for fully harnessing their performance. A resulting monolayer film of neatly tiled 2D nanosheets can provide a molecularly thin interface and a well-defined crystalline surface, leading to the development of unique properties and reactivities. Consequently, considerable efforts have been focused on developing solution-based assembly techniques, including electrostatic self-assembly, the Langmuir–Blodgett (LB) method, and spin coating, to produce highly organized monolayer films.&lt;/p&gt;&lt;p &gt;In the electrostatic self-assembly process, a substrate with an oppositely charged surface is immersed in the nanosheet suspension, and nanosheets are adsorbed on the substrate through electrostatic attraction, forming a monolayer film of nanosheets in a self-assembly fashion.

Compared to the electrostatic self-assembled film, the LB method yields a higher-quality monolayer film of nanosheets without large gaps or overlaps thanks to the surface compression. Similar neat tiling has been achieved by using the spin coating method with optimized deposition parameters. The advantage of this method is its ability to fabricate the film in a shorter period (∼a few minutes), making it most suitable for practical use.&lt;/p&gt;&lt;p &gt;Neatly tiled monolayer films of nanosheets have been applied to modify the surface and interface properties of materials, as exemplified by the performance enhancement of batteries and epitaxial growth of crystalline thin films.
