Enthalpic Contribution of Ni(II) in the Interaction between Carbonaceous Material and Aqueous Solution

open access: yesJournal of Chemistry, 2017
Solid adsorbents were prepared from corn cob that was modified with a solution of HNO3 6 M at different contact times. The solids are characterized by physical N2 adsorption at 77 K to know their surface area by applying the BET model and surface ...

Tuning the Interlayer Distance of Graphene Oxide as a Function of the Oxidation Degree for o‐Toluidine Removal

open access: yesAdvanced Materials Interfaces, Volume 10, Issue 21, July 26, 2023., 2023
Graphene oxide (GO) structures with different interlayer gaps, obtained by varying oxidant amounts, are synthesized for o‐toluidine adsorption. At low oxidation degrees GO is composed of unsplit and isolated graphene planes, whereas at higher KMnO4 content a five‐layer sandwiched configuration is appreciable. Abstract Graphene oxide (GO) with different

Goals and challenges in hybrid software development approaches

open access: yesJournal of Software: Evolution and Process, Volume 33, Issue 11, November 2021., 2021
This work investigates the goals that are pursued in hybrid approaches and how these goals are addressed in the context of a systematic mapping study. Further, it identifies conflicts and challenges that arise in hybrid approaches by a simultaneous use of agile and plan‐based methods for the same activity.

High genetic and morphological diversification of the Euphorbia verrucosa alliance (Euphorbiaceae) in the Balkan and Iberian peninsulas

open access: yesTAXON, Volume 70, Issue 2, Page 286-307, April 2021., 2021
Abstract We explored the diversification of the southern European Euphorbia verrucosa alliance applying molecular (amplified fragment length polymorphism fingerprinting [AFLP], sequencing of the nuclear ribosomal internal transcribed spacer), karyological (relative genome size estimations, chromosome counts) and morphometric methods.

Rδ-Supercontinuous Functions

open access: yesDemonstratio Mathematica, 2014
A new class of functions called ‘Rδ-supercontinuous functions’ is introduced. Their basic properties are studied and their place in the hierarchy of strong variants of continuity which already exist in the literature is elaborated.

Classification as an approach to public key infrastructure requirements analysis

open access: yesIET Software, Volume 13, Issue 6, Page 518-527, December 2019., 2019
Classification schemes and taxonomy of request have focused only on business or software requirements defined by general non‐functional requests. Public key infrastructure (PKI), as a complex system, requires special attention in the process of identification and definition of requests in all parts of the system.
