Language without code: intentionally unusable, uncomputable, or conceptual programming languages

open access: yesJournal of Science and Technology of the Arts, 2017
The esoteric class of programming languages, commonly called esolangs, have long challenged the norms of programming practice and computational culture. Esolangs are a practice of hacker/hobbyists, who don’t primarily think of their work as art.

Removal of Nickel (II) ions from Aqueous Solutions Using Chicken Feather Nanoparticles: Study of Kinetic, Isotherm and Thermodynamic Models [PDF]

open access: yesمحیط زیست و مهندسی آب, 2021
Nickel is highly toxic and directly associate with health risk such as damage to kidney, liver and central nervous system. This study evaluated the potential of a chicken feather for the removal of nickel from aqueous solutions.

Freundlich, Langmuir, Temkin and Harkins-Jura Isotherms Studies of H2 Adsorption on Porous Adsorbents

open access: yesChemistry & chemical technology, 2019
The hydrogen adsorption and desorption isotherms of multiwalled carbon nanotube sample (MWCNT), an iron loaded multiwalled carbon nanotube (Fe_MWCNT), two zeolites (Na_Y_Zeo and NH4_Y_Zeo) and MCM-41 were measured at 77 K and atmospheric pressure by ...

Potential-splitting approach applied to the Temkin–Poet model for electron scattering off the hydrogen atom and the helium ion [PDF]

open access: yes, 2014
The study of scattering processes in few body systems is a difficult problem especially if long range interactions are involved. In order to solve such problems, we develop here a potential-splitting approach for three-body systems.

COMPARISON STUDY BETWEEN DUBININ-RED USHKEVICH AND TEMKIN MODEL FOR ADSORPTION OF MERCURY ONTO ACTIVATED CARBON

open access: yesJournal of Engineering, 2008
Activated carbon has been used as an adsorbent in this work to remove mercury from aqueous solutions. The aim of the work is to test how best activated carbon can be used as an adsorbent for mercury.

Water desorption from rapidly-heated metal oxide surfaces—first principles, molecular dynamics, and the Temkin isotherm

open access: yesJournal of Physics: Condensed Matter, 2018
Quantitative understanding and control of water and impurity desorption from steel surfaces are crucial for high-voltage, pulsed power, vacuum technology, catalysis, and environmental applications.
