Special Issue Information

Dear colleagues,

Over the last two decades, great advances have been recorded in the field of low-dimensional materials— or simple nanomaterials— as a result of the ongoing progress in nanotechnology that provides efficient chemical approaches and advanced methods for the design, development, and study of simple or hybrid nanostructured materials for targeted applications. Low-dimensional materials comprise zero-dimensional (0D) nanostructures (i.e., nanoparticles or nanodots); one-dimensional (1D) nanomaterials like nanowires, nanotubes, or nanofibers; two-dimensional (2D) nanomaterials (i.e., layered materials, polymer membranes or thin films); and even three-dimensional (3D) nanomaterials such as nanoporous materials, hybrid nanocomposites, or nanoflowers. Layered clays, LDHs, chalcogenides, MOFs, inorganic 2D materials, diamondoids, fullerenes, graphene and its analogues, carbon nanotubes or fibers, halloysite nanotubes, polymer and molecular coatings, quantum dots, hierarchical and other mesoporous materials (CMKs, OMS, 2DOM, carbon cuboids, HMS, MCM etc.), inorganic nanotubes, and metal nanoparticles as well as their composite or hybrid derivatives are only some examples of this exciting field of materials. These materials have been extensively studied, both theoretically and experimentally, due to their interesting mechanical, chemical, optoelectronic, catalytic, and (di)electric properties.

The Special Issue on the Chemistry and Physics of Low-Dimensional Materials is open for the submission of manuscripts related to the synthesis, characterization, and study of properties and potential applications of low-dimensional materials. The scope of the Special Issue includes advanced synthesis routes; structural, morphological, and physico-chemical characterization; the evaluation and fundamental understanding of structure–properties relationships; and possible interactions and/or incorporation with other nanomaterials. The topic is not limited to chemical and physical aspects of low-dimensional materials, but is also extended to potential applications of these materials. Experimental and theoretical original research articles as well as review papers are welcome.

The rapidly increased interest in multifunctional nanoelectronic devices, such as wearable monitors, smart robots, and electronic skin, motivated many researchers toward the development of several kinds of sensors in recent years. Flexibility, stability, sensitivity, and low cost are the most important demands for exploiting stretchable or compressible strain sensors. This article describes the formation and characteristics of a flexible, low-cost strain sensor by combining a commercial melamine sponge and a graphene/carbon nanotubes hybrid. The composite that emerged by doping the highly elastic melamine sponge with a highly conductive graphene/carbon nanotubes hybrid showed excellent piezoresistive behavior, with low resistivity of 22 kΩ m. Its function as a piezoresistive material exhibited a high sensitivity of 0.050 kPa−1 that combined with a wide detection area ranging between 0 to 50 kPa. Full article

Hypergolic systems rely on organic fuel and a powerful oxidizer that spontaneously ignites upon contact without any external ignition source. Although their main utilization pertains to rocket fuels and propellants, it is only recently that hypergolics has been established from our group as a new general method for the synthesis of different morphologies of carbon nanostructures depending on the hypergolic pair (organic fuel-oxidizer). In search of new pairs, the hypergolic mixture described here contains polyaniline as the organic source of carbon and fuming nitric acid as strong oxidizer. Specifically, the two reagents react rapidly and spontaneously upon contact at ambient conditions to afford carbon nanosheets. Further liquid-phase exfoliation of the nanosheets in dimethylformamide results in dispersed single layers exhibiting strong Tyndall effect. The method can be extended to other conductive polymers, such as polythiophene and polypyrrole, leading to the formation of different type carbon nanostructures (e.g., photolumincent carbon dots). Apart from being a new synthesis pathway towards carbon nanomaterials and a new type of reaction for conductive polymers, the present hypergolic pairs also provide a novel set of rocket bipropellants based on conductive polymers.
