Developments in semiconductor technology are propelling the dimensions of devices down to 10 nm, but facing great challenges manufacture at sub-10 nm scale. Nanotechnology can fabricate nanoribbons from two-dimensional atomic crystals, such as graphene, with widths below threshold, their geometries and properties have been hard control this Here we find that robust ultrafine molybdenum-sulfide ribbons a uniform width 0.35 be widely formed between holes created MoS2 sheet under electron...
Boron nitride (BN) structures are featured by their excellent thermal and chemical stability unique electronic optical properties.

Abstract Azulenesulfonium salts may be readily prepared from the corresponding azulenes by an S E Ar reaction. These azulene sulfonium are bench‐stable species that employed as pseudohalides for cross‐coupling. Specifically, their application in Suzuki–Miyaura reactions has been demonstrated with a diverse selection of coupling partners. azulenesulfonium possess significant advantages comparison azulenyl halides, which known to unstable and difficult prepare pure form.
Very recently, a new type of two-dimensional layered material MoSi2N4 has been fabricated, which is semiconducting with weak interlayer interaction, high strength, and excellent stability. We systematically investigate theoretically the effect vertical strain on electronic structure MA2Z4 (M=Ti/Cr/Mo, A=Si, Z=N/P) bilayers. Taking bilayer as an example, our first principle calculations show that its indirect band gap decreases monotonically compressive increases. Under critical around 22%,...

Microcapsules with multilayer-thick shells are synthesized by depositing negatively charged nanoparticles around cationic polyamine aggregates crosslinked multivalent counteranions (see Figure and inside cover). Unique among hollow-sphere preparative routes, this rapid green synthesis leads to a robust organic/inorganic hybrid structure, applies wide spectrum of colloidal species, permits the non-destructive encapsulation water-soluble compounds.

It is vital to differentiate catalytic properties between cationic and metallic single atoms at the atomic level. To achieve this, we fabricated well-defined Ni snugged in supported on monolayered CuO. The cations are chemically inert for CO adsorption even 70 K but highly active toward O2 dissociation room temperature. adsorbed O oxidize incoming molecules from gas phase into CO2, which follows Eley-Rideal mechanism, contrast Mars-van Krevelen mechanism CuO-monolayer-supported as well our...
The magnetic proximity effect between the topological insulator (TI) and ferromagnetic (FMI) is considered to have great potential in spintronics. However, a complete determination of interfacial structure has been highly challenging. We theoretically investigate interlayer exchange coupling two FMIs separated by TI thin film, show that particular electronic states contributing can be directly identified through behavior FMIs, together with tunability constant. Such an FMI/TI/FMI not only...
Tunable electromagnetic properties of pristine two-dimensional boron phosphide (h-BP) nanosheet and its semihydrogenated structure were studied by density functional theory computations. In sharp contrast to previously reported tensile strain-induced red shift in semiconductors, the direct gap h-BP undergoes blue under biaxial strain. Once semihydrogenated, not only transform from nonmagnetic semiconductor into metal which is spin-resolved but also exhibits linear response between magnetic...
Graphene oxide (GO) is highly attractive for catalysis because of its large specific surface area and rich chemical structures. However, it has generally been used as a catalyst carrier.
