Experiments have shown that elasticity of disordered filamentous networks with compliant crosslinks is very different from networks with rigid crosslinks. Here, we model and analyze filamentous networks as a collection of randomly oriented rigid filaments connected to each other by flexible crosslinks that are modeled as wormlike chains. For relatively large extensions we allow for enthalpic st...
Extraordinary impact resistance of carbon nanotube film with crosslinks under micro-ballistic impact
The crosslinks of carbon nanotubes (CNT) film has been demonstrated to owing the ability reinforce quasi-static mechanical properties. But it is unclear whether improve ballistic impact resistance CNT film. Here, we investigated with by combining micro-ballistic experiments coarse-grained molecular dynamics (CGMD) simulations. quantitatively characterized in terms specific penetration energy. M...
Here, we develop a technique for curve-fitting of the sulfur K-edge near-edge X-ray absorption fine structure (NEXAFS) to analyze crosslinked vulcanized rubber based on chemical state sulfur. The proposed analytical method provides chain length (Sx), crosslink density, and oxide content simultaneously, it is highly sensitive analysis depth direction. Furthermore, verify aging mechanism using th...
In this paper, we describe our work in NTCIR-10 on the task of cross-lingual link discovery (CLLD). Our proposed method is focused mainly on two aspects in order to accomplish this task: how to find important anchors from an original article in order to crosslink and how to find the correct links to articles in the target language for the original articles. The system first uses online data col...
pBR322 DNA/Restriction endonuclease/8-methoxypsoralen/Black light/Crosslink The pBR322 DNA was irradiated with black light in the presence of 8-methoxypsoralen and digested by various restriction endonucleases including Hin dIII and Rsa I. It was found that for every restriction enzymes examined digestion products specific for pretreated DNA appeared as expected from the inhibition of cleavage ...
Two types of externally plasticized cellulose acetate (CA) were chemically modified using 4,4'-methylene diphenyl diisocyanate (MDI) as crosslinking agent. Crosslinking was performed in the molten state by means of melt mixing in an internal mixer. The viscoelastic properties of the non-crosslinked, externally plasticized CA show typical temperature dependence, similar to conventional thermopla...
In this paper, studies on polyelectrolyte hydrogels of both anionic and cationic type are reported. Partially hydrolysed polyacrylamide-polyvinyl alcohol interpenetrating polymer (IPN) has been synthesized as the anionic hydrogel and chitosan-polyvinyl alcohol interpenetrating polymers have been synthesized as the cationic one, both through a simultaneous IPN method. In both cases, the crosslin...
The acetate ligand exchange with free acetic acid in [Zr 6 O 4 (OH) (O 2 CCH 3 ) 12 ] , used as a model of crosslink migration ]-based coordination vitrimers, has been thoroughly investigated by dynamic 1 H NMR and DFT calculations.
A new crosslinking reaction between two pentagonal rings around the periphery of planar pericondensed aromatic molecules is proposed and its impact on soot nanoparticle formation explored. The mechanism was computed, using density functional theory, an aryl-type σ-radical a rim-based ring attacking another ring. hydrogen migration allowed for double bond forming penta-linked hydrocarbon (APLH) ...
