The present article reviews the self-assembly of oligopeptides to form nanostructures, both in solution and in solid state. The solution structures of the peptides were examined using circular dichroism and dynamic light scattering. The solid state assembly was examined by adsorbing the peptides onto a mica surface and analyzing it using atomic force microscopy. The role of pH and salt concentration on the peptide self-assembly was also examined. Nanostructures within a size range of 3–10 nm were obtained under different conditions.

In the title compound, [HgCl2(C16H28N2Se)], the primary geometry around the Se and Hg atoms is distorted trigonal–pyramidal and distorted square-pyramidal, respectively. The distortion of the molecular geometry in the complex is caused by the steric demands of the ligands attached to the Se atom. The Hg atom is coordinated through two chloride anions, an N atom and an Se atom, making up an unusual HgNSeCl2 coordination sphere with an additional long Hg...N interaction. Intermolecular C—H...Cl interactions are the only identified intermolecular hydrogen-bonding interactions that seem to be responsible for the self assembly. These relatively weak C—H...Cl hydrogen bonds possess the required linearity and donor–acceptor distances. They act as molecular associative forces that result in a supramolecular assembly along the b-axis direction in the solid state of the title compound.

<div><div><div><p>Substoichiometric aerobic oxidation of the high-spin organometallic compound (tmeda)Fe(CH2tBu)2 (tmeda = N,N,N’,N’- tetramethylethylenediamine) in toluene or THF solution leads to the self-assembly of a magic-sized all-ferrous oxide cluster containing the Fe9O6 subunit and bearing organometallic and diamine ligands. Mössbauer studies of the cluster and the reference complex (tmeda)Fe(OCPh3)2 are consistent with the all-ferrous assignment, and magnetometry reveal considerable antiferromagnetic coupling between Fe atoms in the cluster and frustrated antiferromagnetic interactions between clusters in the solid state.</p></div></div></div>

Two new polymeric MnII complexes, {[Mn(1,2-BDC-F4)(H2O)3](EtOH)}n (1) and [Mn(1,2- BDC-F4)(H2O)2(DMF)]n (2), have been prepared from the reaction of MnII acetate with 3,4,5,6- tetrafluoro-benzene-1,2-dicarboxylic acid (1,2-H2BDC-F4) using different solvents, and characterized by elemental analysis, IR spectroscopy, thermogravimetric (TG) analysis, and single-crystal Xray structure analysis. Both complexes crystallize in the triclinic space group P1̄ and have similar one-dimensional double chain structures, consisting of a unique arrangement of 8-membered and 14- membered rings. The effects of solvent as ligand and/or guest on the self-assembly processes of the supramolecular networks and on their photoluminescence properties in the solid state are discussed.

In the self-assembly process of β-Si3N4 (SN)/316L stainless-steel (SUS316L) composite materials tailored via sintering of powder mixtures, the formation of a SN agglomerate resulting from condensation–dispersion reactions during the stirring of SN/SUS316L was found to play an important role in improving the thermal conductivity. Moreover, the obtained SN secondary particle groups connected to form a network through diffusion-limited aggregation. In particular, it was shown that the sample prepared at the milling speed of 150 r/min has a similar particle group area (about 1.38 μm2) to that at 120 r/min, but a higher κ (increased from 9.5 W m−1 K−1 to 11.5 W m−1 K−1). To quantitatively evaluate the microstructural morphology of the texture of the self-assembled composite material, global parameters τ( q) and D q and local parameters α( q) and f( α) were determined via multifractal analysis. These characteristics of the anisotropy, dispersion, and cohesiveness of the particle network in the material texture could be analyzed together with the capacity dimension D0, information dimension D1 (configuration entropy), correlation dimension D2, and α( q) (related to internal energy). The results suggest that α( q) reflects the differences in the cohesion of the additive particle agglomeration that constitutes the self-assembly process under the solid-state reaction.
