We explored a facile method for grafting bi-functional groups terminated branched polyphosphazene on carbon fibers via direct epoxy amination with an aqueous ammonia solution. The branched polyphosphazene with abundant β-hydroxyl groups and amino groups significantly changes the chemical composition...

Reconstructing dynamic urban scenes from unmanned aerial vehicle (UAV) full-motion videos is a vital task with significant applications in urban planning, traffic analysis, and autonomous navigation. However, modeling these scenes is challenging due to their large scale and, more importantly, the ev...

Supramolecular β-cyclodextrin (β-CD) was used as a soft template for the fabrication of long silver nanowires. A novel design using self-assembled β-CD for the reduction of silver ions was studied. The concentrations of iron chloride, silver nitrate, and the template were controlling factors for the...

Terephthalate (TA) intercalated layered double hydroxides (LDHs) were synthesized using hydroxides as raw materials, and poly(ethylene terephthalate) (PET)/LDH nanocomposites with different contents of TA intercalated LDHs were prepared by in-situ polymerization. The structure, morphology and therma...

A finite-element scheme has been developed, including a section of reservoir rock, cement stone, casing and perforation channels. It is noted that in order to exclude the occurrence of stress concentrators at the casing – cement stone and cement stone – rock contacts, contact elements are specified...

The multistep procedures for preparing novel anionic spherical polyelectrolyte brushes (ASPB) by grafting sodium-p-styrenesulfonate (SSS) from the surface of &#947;-methacryloxypropyl trimethoxy-silane modified SiO2 nanoparticles were demonstrated. The morphology of ASPB was characterized by Tra...

Introduction: While healthcare systems have to prepare for the impact on global health due to climate change, the healthcare sector must reduce carbon emissions and become environmentally sustainable. This paper provides an overview of how a healthcare system in Singapore, the National University He...

The crystallization of polymers, caused by flow fields in the melt, has been the subject of extensive studies for many years. In this study, we use periodical shear to induce polypropylene to form multi-layer structure, which is usually observed in plants. Two interesting points were found: firstly,...

The nanocarrier is linked to the core and shell by hydrogen bond. This drug delivery system represents a smart, biodegradable, and pH-sensitive nanocarrier for breast cancer therapy. These drug nanocarriers were linked by hydrogen bond from –NH2 on chitosan and –OH on mesoporous silica nanoparticle...

Collisionless magnetic reconnection is postulated to be active in many regions of the heliosphere, where the physics and formation of heliospheric structures are influenced by pickup ions (PUIs). Recent investigations suggest that the presence of PUIs may enhance the reconnection rate due to PUI-ind...

Abstract This work presents a global distribution of daytime lunar tidal winds at altitudes of 80–115 km based on Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics observation. The lunar tidal wind dynamo currents are then derived using the observed winds for the first time, and its lunar...

Inclusive electron scattering at carefully chosen kinematics can isolate scattering from the high-momentum nucleons in short-range correlations (SRCs). SRCs are produced by the hard, short-distance interactions of nucleons in the nucleus, and because the two-nucleon (2N) SRCs arise from the same N-N...
