The aim of this work was to separate ethanol in an experimental adsorption–desorption device. We focused on concentrating by adsorption onto granulated activated carbon its gaseous phase, which produced stripping a matrix with different concentrations (2, 5, 10, and 15% v/v). For adsorption, three kinds (GAC) were used, marked as GAC1, GAC2, GAC3. separation product had higher concentration tha...

In secure information flow analysis, the classic Denning restrictions allow a program’s termination to be affected by the values of its H variables, resulting in potential information leaks. In an effort to quantify such leaks, in this work we study a simple imperative language with random assignments. As a thought experiment, we propose a “stripping” operation on programs, which eliminates all...

Three 35-L anaerobic digesters fed on source segregated food waste were coupled to side-stream ammonia stripping columns and operated semi-continuously over 300 days, with results in terms of performance and stability compared to those of a control digester without stripping. Biogas was used as the stripping medium, and the columns were operated under different conditions of temperature (55, 70...

Aptasensors based on stripping voltammetry exhibit several advantages, such as high sensitivity and multi-target detection from stripping voltammetric technology, and high selectivity from the specific binding of apamers with targets. This review comprehensively discusses the recent accomplishments in signal amplification strategies based on nanomaterials, such as metal nanoparticles, semicondu...

Temperature-dependency of back-extraction behavior inert platinum group metals (PGMs) like Ru(III) and Rh(III) has been investigated in a biphasic system consisting H2C2O4(aq) betainium bis(trifluoromethylsulfonyl)amide ([Hbet][Tf2N]) after extracting these PGMs as well that non-inert Pd(II). At 298 K, Pd(II) [Hbet][Tf2N] phase was stripped high efficiency (78.8%) by 0.1 M H2C2O4 within 2 min. ...

This communication reports the identification of gas phase isomers in monolayer-protected silver clusters. Two different isomers of Ag11(SG)7(-) (SG-gulathione thiolate) with different drift times have been detected using combined electrospray ionization (ESI) and ion mobility (IM) mass spectrometry (MS). Surface induced dissociation (SID) of the 3(-) charge state of such clusters shows charge ...

INTRODUCTION There are various treatment modalities to remove the black patches of melanin pigmentation. The aim of the study is to clinically compare the diode laser ablation and surgical stripping technique for gingival depigmentation and to evaluate their effect on the histological changes in melanocyte activity. MATERIALS AND METHODS A total of 40 sites of 20 patients with bilateral melan...
