The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

The first organocatalyzed multicomponent domino reactions of aryl ketones, aldehydes and malononitrile were carried out successfully to afford multisubstituted cyclohexa-1,3-dienamines in satisfactory yields.

Identification of major histocompatibility complex (MHC)-associated peptides recognized by T-lymphocytes is a crucial prerequisite for the detection and manipulation of specific immune responses in cancer, viral infections, and autoimmune diseases. Unfortunately immunogenic peptides are less abundant species present in highly complex mixtures of MHC-extracted material. Most peptide identificati...

Three-dimensional (3D) porous metal and metal oxide nanostructures have received considerable interest because organization of inorganic materials into 3D nanomaterials holds extraordinary properties such as low density, high porosity, and high surface area. Supramolecular self-assembled peptide nanostructures were exploited as an organic template for catalytic 3D Pt-TiO2 nano-network fabricati...

In this study, B12N12 Nano ring has been selected because it consist of four 6-side rings and polar bonds B-N which in comparison with non-polar bonds C-C, is more suitable for the study of the absorption of other compounds. So reactivity and stability of Benzene alone and in the presence B12N12 nano ring field checked. To determine the non-bonded interaction energies between Benzene and B12N12...

Fungal Keratitis In article 2202409, Shaozhen Zhao, Zhongwei Niu, Ruibo Yang, and co-workers report a peptide conjugate nano-assembly (PCNA) that permeates corneal stroma kills the hyphae without irritating ocular cornea. PCNA with nano-assembled structure assembly–disassembly behavior could serve as foundation of new therapy for fungal keratitis.
