The influence of the chemical functionalization graphene on interfacial bonding characteristics between and polymers was investigated using molecular mechanics dynamics simulations. simulations show energy shear stress polymer increase with concentration functionalized groups. Our indicated that some specific modifications play important roles in determining strength polymer. Therefore, attachment suitable groups a reasonable to surface may be an effective way significantly improve load...
Abstract A simple way of synthesizing carbon nanotube (CNT)/graphene (GN) nanoscroll core/shell nanostructures is demonstrated using molecular dynamics (MD) simulations. The simulations show that GN sheets can fully self‐scroll onto CNTs when the CNT radius larger than a threshold about 10 Å, forming stable structure. Increasing length sheet results in multilayered (CNS) shells exhibit tubular structure similar to multiwall CNTs. distances between and wall or adjacent walls are 3.4 Å. It...
Developing a respiratory analysis disease diagnosis platform for the H2S biomarker has great significance real-time detection of various diseases. However, achieving highly sensitive and rapid gas at parts per billion level low temperatures is one most critical challenges developing portable exhaled sensors. Herein, Cu2O-multiwalled carbon nanotube (MWCNT) heterostructures with excellent sensitivity to room temperature lower were successfully synthesized by facile two-dimensional (2D)...
We demonstrated a novel method to produce core/shell composite nanowires (NWs) by self-scrolling carbon nanotubes (CNTs) onto copper NWs via forced-field-based molecular dynamic (MD) simulations. When large diameter CNTs are placed beside the NWs, approach collapse, and self-scroll resulting in coaxial NWs. It is found that van der Waals force plays an important role formation of The expected outcome this determine various strategies on how Coaxial represent class nanoscale building blocks...
Developing a portable and compact sensor for room temperature detection of H2S in exhaled breath health assessment presents considerable technical challenges. This work successfully synthesized Cu2O/ZnO heterostructures with excellent gas sensitivity to at lower temperatures using two-dimensional (2D) electrodeposition situ assembly method the application semisine wave voltage as well CuZnO nanoarrays deposited under direct current voltage.

Ammonia (NH3) sensors based on carbon/silicon (C/Si) heterojunctions are demonstrated at room temperature (RT). Upon exposure to NH3 molecules (0.2 ml l−1) RT, the interface capacitance of C/Si junction increases dramatically, about 230%. The results show that junctions have high gas sensitivity, rapid response and recovery speed RT. This phenomenon can be attributed change potential barrier width junction, which is caused by adsorption molecules. greatly amplify detection sensitivity...
Abstract The distribution and migration characteristics of weak gel in the core were observed by combining nuclear magnetic resonance (NMR) imaging technology with displacement experiment, oil features different polymer-weak combinations examined visualization experiments. Three combination patterns polymer designed: waterflooding + flooding (pattern 1), 2), 3). pressure variations, T 2 spectra, images, efficiencies under analyzed. results show that images can not only provide direct...
Thienoisoindigo as a popular conjugated skeleton has been constantly applied in the construction of organic optoelectronic materials. Exploring its new applications fluorescent sensors and bioimaging is helpful to extend potential. In this work, thienoisoindigo fluorophore was first selected building block be near-infrared materials with an aggregation-induced emission manner through introducing triarylamine, thiophene-bridged N,N-dimethyl styrene, respectively. These agents showed possessed...
Tuberculosis (TB) is a chronic infectious disease caused by the etiological agent Mycobacterium tuberculosis (MTB). Because majority of TB patients come from poor economic backgrounds, development simple, specific, low-cost, and highly sensitive detection method for pathogen extremely important prevention treatment this disease.

Molecular dynamics (MD) simulations were used to study the interaction energy between single-walled carbon nanotubes (SWNTs) and polyphenylacetylene (PPA). The "wrapping" of by PPA chains was computed. influence nanotube chirality, temperature, chemical modification on interfacial adhesion nanotube−PPA investigated. results showed that SWNTs is strongly influenced chirality but temperature could be negligible. For with similar molecular weights, diameters, lengths, armchair-type may best for...
