The dynamic behaviours of host frameworks and guest molecules have received much attention for their great relevance with smart materials, but little has been developed to control or understand the host-guest interplay. Here we show that the confined guest can utilize not only molecular static effects but also bulk dynamic properties to control the host dynamics. By virtue of the three-dimensio...

New host-guest materials have been prepared by incorporation of a home-made organic probe displaying a pyrene motif and a phosphonate function into a regular amphiphilic copolymer. Using powder X-Ray diffraction, photoluminescence and FT-IR spectroscopy, we have been able to study the non-covalent interactions between the host matrix and the guest molecule in the solid state. Interestingly, we ...

Encapsulation of guest molecules within the interior cavities of dendrimers is promising, but high generation dendrimers show limited encapsulation capacity due to their dense surface shell. Here, for the first time, we prove that high generation polyamidoamine dendrimers, such as generation 8 and generation 10, are able to encapsulate hydrophobic guests using NMR spectroscopy. Guest molecules ...

This research work presents a photochromic flexible film, for fast and real-time detection differentiation of UVA and/or UVB radiation. The host–guest system was produced by confining 7% (w/w) highly fluorinated ionic liquid in polysulfone.

A known generalization of the Stillinger-Lovett sum rule for a guest charge immersed in a two-dimensional one-component plasma (the second moment of the screening cloud around this guest charge) is more simply retrieved, just by using the BGY hierarchy for a mixture of several species; the zeroth moment of the excess density around a guest charge immersed in a two-component plasma is also obtai...

The thermal characteristics of seven crystals with [Ni(NCS),(vpy),] (vpy = 4-vinylpyridine) as host were analysed by thermal gravimetric analysis (TGA) and differential thermal analysis (DTA). N o preferential guest loss for the clathrates with pairs of guests was observed. The enthalpy of the 'guest release reaction' for each clathrate was obtained from the DTA experiments. Solubility studies ...

I/O virtualization performance is an important problem in KVM. In this paper, we evaluate KVM I/O performance and propose several optimizations for improvement. First, we reduce VM Exits by merging successive I/O instructions and decreasing the frequency of timer interrupt. Second, we simplify the Guest OS by removing redundant operations when the guest OS operates in a virtual environment. We ...

Clathrates are crystalline inclusion compounds formed by a physically stable reaction between host and guest molecules. Gas hydrate and hydroquinone (HQ) clathrate are one of the most studied and welldefined clathrate compounds. In this study, guest-free, CO2-loaded, CH4-loaded and CO2/CH4-loaded HQ clathrates were synthesized by gas-phase reaction and recrystallization. In addition, pure CO2 a...

Due to the quick development of mobile, ubiquitous, cloud, network and communication systems and applications, many computer and communication systems, wired or wireless, have been proposed to provide their users (human or other systems) with different services. However, hackers may anytime and anywhere attack these systems for stealing a company’s business secrets or a person’s credit card inf...

a novel podand based anion receptor bearing benzimidazole motifs as recognition sites was designed and synthesized by reaction of 1,7-bis(2'-methylbenzoate)-1,4,7-trioxaheptane and phenylenediamine. the binding properties of anionic guest with this receptor were studied using uv-vis and fluorescence spectroscopy. these studies revealed that this receptor exhibit selective recognition towards f- ...
