However, how to uniformly coat a dense layer of carbon on nano sized Li2S is still challenge so far. Here, we utilized a novel flowable ionic liquid (1-Ethyl-3-methylimidazolium dicyanamide) as a carbon precursor to uniformly...

Two novel nano-cage compounds, 8 and 9, were prepared by self-assembly of the ruthenium complexes 4 and 5, and the tripodal donor 1. The cytotoxicity of 8 was found to be considerably stronger than that of cisplatin. The complex 8 inhibited tumor cell proliferation by interfering into regulatory pathways of the cell cycle via apoptosis.

The GroEL/GroES chaperonin system of Escherichia coli forms a nano-cage allowing single protein molecules to fold in isolation. However, as the chaperonin can also mediate folding independently of substrate encapsulation, it remained unclear whether the folding cage is essential in vivo. To address this question, we replaced wild-type GroEL with mutants of GroEL having either a reduced cage vol...

GroEL and GroES form a chaperonin nano-cage for single protein molecules to fold in isolation. The folding properties that render a protein chaperonin dependent are not yet understood. Here, we address this question using a double mutant of the maltose-binding protein DM-MBP as a substrate. Upon spontaneous refolding, DM-MBP populates a kinetically trapped intermediate that is collapsed but str...

Protein self-assembly, through specific, high affinity, and geometrically constraining protein-protein interactions, can control and lead to complex cellular nano-structures. Establishing an understanding of the underlying principles that govern protein self-assembly is not only essential to appreciate the fundamental biological functions of these structures, but could also provide a basis for ...

OBJECTIVE To retrospectively compare the efficacy of the titanium mesh cage (TMC) and the nano-hydroxyapatite/polyamide66 cage (n-HA/PA66 cage) for 1- or 2-level anterior cervical corpectomy and fusion (ACCF) to treat multilevel cervical spondylotic myelopathy (MCSM). METHODS A total of 117 consecutive patients with MCSM who underwent 1- or 2-level ACCF using a TMC or an n-HA/PA66 cage were s...

Large-scale MoO2/carbon composites with a cage-like nanostructure have been synthesized by a simple hydrothermal reduction process. During the hydrothermal process, ammonium molybdate tetrahydrate ((NH4)6Mo7O24·4H2O) was employed as starting material and ascorbic acid as a structure directing agent, reductive agent and carbon source. MoO2/C nanospheres with diameters of about 15-25 nm were inte...

A comprehensive molecular dynamics study to shed light on the existence of SiC based cage nanostruc-tures Si m C n , together with their stability, structural and other properties, in the range of compositions with n/(n + m) from 0.4 to 0.6 has been carried out using an efficient semi-empirical Hamiltonian scheme. Through this study, a series of self-assembled stable (even up to 2000 K) SiC bas...

Annealing of C60 in hydrogen at temperatures above the stability limit of C-H bonds in C60H x (500-550 °C) is found to result in direct collapse of the cage structure, evaporation of light hydrocarbons, and formation of solid mixture composed of larger hydrocarbons and few-layered graphene sheets. Only a minor part of this mixture is soluble; this was analyzed using matrix-assisted laser desorp...
