Semi-flexible mixture, as a rigid and flexible pavement material, has good rutting resistance water stability, but its low-temperature cracking shear are poor. This paper studies characterizes the of semi-flexible mixtures modified by redispersible emulsion powder epoxy resin. The performance matrix asphalt mixture cement grouting material with different polymer contents were investigated. flex...

Flexible butyl interconnection segments are synthetically incorporated into an electronically conductive poly(pyrene methacrylate) homopolymer and its copolymer. The insertion of butyl segment makes the pyrene polymer more flexible, and can better accommodate deformation. This new class of flexible and conductive polymers can be used as a polymer binder and adhesive to facilitate the electroche...

A robust, porous, catenated coordination polymer based on a neutral, flexible imidazole-derived tripodal ligand (a 'tripodal imidazole framework', TIF) reversibly absorbs vapours and gases, particularly CO2.

The realization of a complete tandem polymer solar cell under ambient conditions using only printing and coating methods on a flexible substrate comprises a fully scalable

Progress in the development of a modular approach towards flexible anion-binding and sensing systems is reviewed within the context of related developments in conformationally flexible anion- and salt-binding hosts. The transferability of concepts and structural features across chemically distinct systems is emphasised along with the use of modular components in polymer and gel-phase systems.

Recent theoretical progress has explained the physics of knotting of semiflexible polymers, yet knotting of flexible polymers is relatively unexplored. We herein develop a new theory for the size distribution of knots on a flexible polymer and the existence of metastable knots. We show the free energy of a flexible molecule in a tube can be mapped to quantitatively reproduce the free energy dis...

We have studied the occurrence of stochastic resonance when a flexible polymer chain undergoes a single-file translocation through a nano-pore separating two spherical cavities, under a time-periodic external driving force. The translocation of the chain is controlled by a free energy barrier determined by chain length, pore length, pore-polymer interaction, and confinement inside the donor and...

A simple, yet innovative, method is presented for fabricating high-aspect-ratio polymer nanohairs (aspect ratio >20) on a solid substrate by sequential application of molding and drawing of a thin polymer film. The polymer film was prepared by spin coating on a rigid or flexible substrate, and the temperature was raised above the polymer's glass transition while in conformal contact with a poly...

in previous years, various studies have been carried out on engineering education and training. based on the results and world transforms, developed strategies have been offered in academic or industrial world, which start from preparation for information technology era to focusing on sustainable developments and global engineering in current age. on the other side, education from research univ...

Polymer translocation through a nanometer-scale pore assisted by chaperones binding to the polymer is a process encountered in vivo for proteins. Studying the relevant models by computer simulations is computationally demanding. Accordingly, previous studies are either for stiff polymers in three dimensions or flexible polymers in two dimensions. Here, we study chaperone-assisted translocation ...
