bifunctional acidic ionic liquids, having both h-imidazolium and -so3h groups as cation moieties (h-bfails) and cf3so3- as anion, were synthesized in high yields. these h-bfails showed significant hydrophilic properties, lower acidity and higher thermal stability relative to common ionic liquids, due to their unique structures. the (propyl or butyl-3-sulfonic) imidazolium trifluoromethane sulfo...

ost people consider unaccounted-for water and leakage to be the same thing. They are not. Leakage is a part, and sometimes a large part, of unaccounted-for water, but it is just one piece of the puzzle. Unaccounted-for water is the difference between the amount of water produced, or purchased, and the amount of water sold to all customers. Unaccounted-for water includes underground leakage; una...

Modeling and Evaluating Information Leakage Caused by Inferences in Supply Chains

We analyze a model of bargaining over new ideas. The model accounts for the problem of information leakage, i.e., the diffusion of information about the idea before and after the idea is implemented. We analyze the effects of information leakage on the distribution of rents within firms and the firms’ stability to the introduction of innovation. In the model, the distribution of rents in a firm...

A “home” sharing environment consists of the data sharing relationships between family members, friends, and acquaintances. We argue that this environment, far from being simple, has sharing and trust relationships as complex as any general-purpose network. Such environments need strong access control and privacy guarantees. We show that avoiding information leakage requires both to be integrat...

This article develops a model of the upstairs market where order size, beliefs, and prices are determined endogenously. We test the model’s predictions using unique data for 5,625 equity trades during the period 1985 to 1992 that are known to be upstairs transactions and are identified as either buyer or seller initiated. We find that price movements prior to the trade date are significantly po...

choline oxidase (chox) was chosen as a model enzyme for evaluating the performance of cnts’ functional groups for development of enzyme electrodes. cnts were functionalized with carboxylic acid, amine or amide groups. carboxylic acid, amine and amide functionalized cnts were obtained by acid treatment, ethylenediamine or tetraethylenepentamine chemically modification and ammonia plasma treatmen...

fe3o4 magnetic nanoparticles modified with 1-octyl-3-methylimidazolium bromide([c8mim]-fe3o4) were used for the removal of reactive red 141 (rr141) and reactive yellow 81 (ry81) as model azo dyes from aqueous solution. the mean size and the surface morphology of the nanoparticles were characterized by tem, xrd and ftir techniques. adsorption studies of two dyes were performed under different ex...

Signature can be used to verify the integrity of both a message and identity signer, whereas encryption ensure confidentiality message. In past, cryptography researchers have studied proposed numerous certificateless signcryption (CLSC) schemes combine benefits signature encryption. However, these may not robust enough withstand side-channel attacks. Through such attacks, an attacker constantly...
