Biological ion channels feature angstrom-scale asymmetrical cavity structures, which are the key to achieving highly efficient separation and sensing of alkali metal ions from aqueous resources. The clean energy future lithium-based storage systems heavily rely on ionic separations. However, artificial recreation such a sophisticated biostructure has been technically challenging. Here, tunable design concept is introduced fabricate monovalent ion-selective membranes with asymmetric...

Abstract Lithium consumption is estimated to face a considerable rise in the next decade; thus, finding new reproducible lithium resources such as brine deposits and seawater has become fast‐growing research topic. However, Li + extraction from these challenging due its low concentration presence of other monovalent cations exhibiting identical chemical properties. Here, it discovered that tannic acid (TA) inside graphene oxide (GO) nanochannel acts natural ion trapper, which possesses...

With an ageing population, hearing disorders are predicted to rise considerably in the following decades. Thus, developing a new class of artificial auditory system has been highlighted as one most exciting research topics for biomedical applications. Herein, design biocompatible piezoresistive-based hair cell sensor is presented consisting highly flexible and conductive polyvinyl alcohol (PVA) nanocomposite with vertical graphene nanosheets (VGNs). The bilayer hydrogel demonstrates...

A Lift Dispatching System (LDS) is a typical real-time system that highly complicated in design and implementation. This article presents the formal design, specification, modeling of LDS using denotational mathematics known as Real-Time Process Algebra (RTPA). The conceptual model introduced initial requirements for system. architectural created RTPA methodologies refined by set Unified Data Models (UDMs). static behaviors are specified (UPMs) lift dispatching serving processes. dynamic...

This article presents results from a numerical study of turbulent slot jet impinging on concave surface. Five different low Reynolds number k-? models were evaluated to predict the heat transfer under two dimensional steady jet. The effects flow and geometrical parameters (e.g. jet-to-target separation distance) have been investigated. Yap correction is applied for reducing over-prediction Nusselt in near wall region. It shown that among tested this study, LS-Yap model capable predicting...

We consider the problem of secret key establishment (SKE) in presence a passive adversary, Eve, when Alice and Bob are connected by pair independent discrete memoryless broadcast channels opposite directions. refer to this setup as 2DMBC. define secret-key capacity provide lower bound on proposing two-round SKE protocol. also prove an upper show that two bounds coincide case degraded 2DMBCs.

For a nontrivial finite group [Formula: see text] different from cyclic of prime order, the intersection graph is simple undirected whose vertices are proper subgroups and two joined by an edge if only they have intersection. In this paper we characterize all groups with planar graphs. It turns out that few solvable Also classify graphs bipartite, triangle free forests.

For a finite group G different from cyclic of prime power order, we introduce an undirected simple graph {\Delta} (G) whose vertices are the proper subgroups which not contained in Frattini subgroup and two H K joined by edge if only G\kern -1pt =\kern \langle H, K\rangle . In this paper study show that it is connected determine clique chromatic number obtain bounds for its diameter girth. We classify groups with complete graphs also domination 1. Also independence at most 7, then solvable.
