Selective protein channels in cell and nuclear membranes act as gateways to control the passage of molecules across. The selectivity of these channels stems from attractive potentials of the binding sites in the transmembrane proteins. These channels can filter out small volume of solutions with high precision. Motivated from this phenomenon, we report biomimetic facilitated transport modality ...

SWCNT can be conceptualized by wrapping a one-atomic-layer thick graphene into a hollow cylinder. As shown in Figure 1, the wrapping way is represented by the chiral vector (n, m), which denote the number of unit vectors along two directions in the crystal lattice of graphene sheet.1 Because of the symmetry and unique electronic structure of graphene, the structures of SWCNTs strongly affect th...

Nuclear energy is among the most viable alternatives to our current fossil fuel-based energy economy. The mass deployment of nuclear energy as a low-emissions source requires the reprocessing of used nuclear fuel to recover fissile materials and mitigate radioactive waste. A major concern with reprocessing used nuclear fuel is the release of volatile radionuclides such as xenon and krypton that...

Suppose many messages are encrypted using a public-key encryption scheme. Imagine an adversary that may adaptively ask for openings of some of the ciphertexts. Selective opening (SO) security requires that the unopened ciphertexts remain secure, in the sense that this adversary cannot derive any nontrivial information about the messages in the unopened ciphertexts. Surprisingly, the question wh...

We formalize the security notions of non-malleability under selective opening attacks (NM-SO security) in two approaches: the indistinguishability-based approach and the simulationbased approach. We explore the relations between NM-SO security notions and the known selective opening security notions, and the relations between NM-SO security notions and the standard non-malleability notions.

Thin-layer chromatography of α-amino acids has been performed on layers prepared from a 1:4 stannic arsenate–cellulose mixture. RF values of the amino acids were determined after development with a variety of mobile phases. Important synthetic ternary separations have been achieved on the basis of different RF values. Lysine and threonine have been selectively separated and quantitatively deter...

Enhancing the fluxes in gas separation membranes is required for utilizing the membranes on a mass scale for CO2 capture. Membrane thinning is one of the most promising approaches to achieve high fluxes. In addition, sophisticated molecular transport across membranes can boost gas separation performance. In this review, we attempt to summarize the current state of CO2 separation membranes, espe...

A sequential separation scheme has been devised for the quantitative analytical separation of 27 different metal ions. Five different Chromatographic and ion-exchange columns are used to separate the metal ions into groups. The metal ions of each group are eluted separately from each column by means of selective eluents. Following separation, the metal ions are determined by titrimetry, flame s...
