The reversibility of the Diels-Alder reaction can be used advantageously in polyurethane materials to endow them with recyclable, thermally reversible properties and self-healing ability to expand their application range. In this paper, linear and crosslink polyurethanes based on HTPB, which exhibit thermal reversibility through Diels-Alder and retro Diels-Alder reactions, were prepared and cha...

We demonstrate that isophthalic acid-ended telechelic poly(1,5-cyclooctadiene)s (APCODs) form thermo-reversible gels in non-polar solvent with a unique molecular mechanism for their thermo-reversibility. Like other associative telechelic polymers, A-PCODs form “flower-like” micelles at low concentration and form gels through bridging at higher concentration which exhibit linear viscoelasticity....

The tunable photo-induced electronic property of the Cs2[{Mo6Bri8}Bra6] and Br2[{Ta6Bri12}(H2O)a6] octahedral metal cluster-based compounds was characterized by zeta potential measurement upon irradiation ultraviolet–visible (UV–Vis) light. enhancement charge on surface [{Mo6Bri8}Bra6]2- anion caused increased negative potential. Both showed dependence as a function light excitation. This will ...

As a generalization of the triple I method, the universal triple Imethod is investigated from the viewpoints of both fuzzy reasoningand fuzzy controller. The universal triple I principle is putforward, which improves the previous triple I principle. Then,unified form of universal triple I method is established based onthe (0,1)-implication or R-implication. Moreover, the reversibilityproperty o...

This paper a t tempts to clarify two distinct notions of "reversibility": (i) Uniformity of implementation of parsing and generation, and (it) reversibility as an inherent (or intrinsic) property of grammars. On the one hand, we explain why grammars specified as definite programs (or the various related "unification grammars") lead to uniformity of implementation. On the other hand, we define d...

This is a collection of 15 revised and expanded papers from the 1991 Berkeley ACL workshop of the same title. Collectively, the contributions cover all the main theoretical and practical motivations for reversibility of grammars: increased accuracy of description gained; economy of development and maintenance effort; consistency of language use in translation or interface applications; and poss...

Mesoporous anatase TiO2 spheres (MATS) are elaborated via microwave-assisted rapid crystallization of hydrous colloidal (HTCS) self-template. Tuning the hydrothermal and calcination temperatures allow for textural property-controllable synthesis. The optimal MATS demonstrated as a promising cathode material aluminium-ion batteries (AIBs) show superior rate capacity performances. Their large sur...

Motivated by the construction of invariants of links in 3-space, we study spin models on graphs for which all edge weights (considered as matrices) belong to the Bose-Mesner algebra of some association scheme. We show that for series-parallel graphs the computation of the partition function can be performed by using seriesparallel reductions of the graph appropriately coupled with operations in...

Augmented marked graphs were first introduced in 1997 (Chu & Xie, 1997). They are not well known as compared to other sub-classes of Petri nets such as free-choice nets (Desel & Esparza, 1995), and the properties of augmented marked graphs are not studied extensively. However, augmented marked graphs possess a structure which is desirable for modelling shared resources, and for this reason, the...
