Abstract Two ferrocene‐based NHCs of the type fc[(NR) 2 C:] ( 1 R ; fc=1,1’‐ferrocenylene) containing benzylic N ‐substituents were synthesised from corresponding formamidinium compounds H[BF 4 ] by reaction with LiN(SiMe 3 ) . In case R=CH Ph (Bn), carbene was characterised through trapping reactions sulfur and selenium, which afforded fc[(NBn) CS] Bn S) CSe] Se), respectively. A thermally sta...

RAT ALLOANTISERA OF THE FOLLOWING SPECIFICITIES WERE OBTAINED AFTER SINGLE SKIN GRAFT REJECTION: DA anti-BN, BN anti-DA, DA anti-Lewis, and Lewis anti-DA. Anti-alloantibodies were raised by injecting the first two alloantisera into (DA x BN)F(1) hosts and the last two alloantisera into (DA x Lewis)F(1) hosts. In this manner, four anti-alloantisera were raised: anti-(DA anti-BN), anti-(BN anti-D...

Graphene/hexagonal boron nitride (h-BN) heterostructures have attracted a great deal of attention in recent years due to their unique and complementary properties for use in a wide range of potential applications. However, it still remains a challenge to synthesize large-area high quality samples by a scalable growth method. In this work, we present the synthesis of both in-plane and stacked gr...

The structures and stability of 531 novel boron nitride substituted isomers of 12-crown-4 etherverified theoretically. For a collection of 23 selected BN isomers, structural geometry, vibrationalstability, energy gaps, natural bond population analysis, and nonlinear optical responses investigatedtheoretically. The changes of standard enthalpies for ionization reactions and electron affinityreac...

in this work we use density functional theory based on the ultra-soft pseudo-potential to calculate thestructural, mechanical and thermal properties of narrow single walled bn, aln and gan nanotubes.the electron-electron interactions were expressed within the local density approximation (lda). wehave also obtained the phonon dispersion and elastic constants of these nanotubes using the densityf...

A reduced graphene oxide (RGO)-ZnIn(2)S(4) nanosheet composite was successfully synthesized via an in situ controlled growth process. The as-obtained RGO-ZnIn(2)S(4) composite showed excellent visible light H(2) production activity in the absence of noble metal cocatalysts.

Ternary hybrid film composed of -zirconium phosphate nanosheet, 1,2-bis(dimethylchlorosilyl)ethane and polypyrrole was prepared by anodic electrodeposition. In the hybrid film, ordered -zirconium nanosheets with grafts by silylation lay down parallel to the substrate and the polypyrrole molecules were intercalated between the nanosheets. The electrochemical measurements confirmed that the hyb...

The carbon-coated TiO2(B) nanosheet composite synthesized by one-step hydrolysis of TiCl3 followed by vacuum annealing and air annealing delivers outstanding electrochemical performance as a negative electrode for Li-ion batteries, i.e. reversible capacity above 150 mA h g(-1) at 30 C (10 A g(-1)).

Mesoporous MnO2 nanosheet arrays have been directly grown on nickel foam current collectors and exhibited a reversible capacity as high as 1690 mA h g(-1) even after one hundred cycles at 100 mA g(-1). They also reveal good rate capability and excellent cycling stability.

Flower-like CdSe architectures composed of ultrathin nanosheets were prepared via a facile solvothermal method. A relationship was established between the solvothermal temperature and the product structure, and thus the photocatalytic activity. When compared with well-studied CdSe quantum dots, the ultrathin nanosheet assemblies exhibited a better photocatalytic H2 evolution activity under visi...
