Simulation of Hydrogen Isotopes Accumulation Processes in Materials in the Presence of Chemical Traps

open access: yesEurasian Chemico-Technological Journal, 2019
The accumulation of hydrogen inside a solids occurs in traps of a different nature. The following things are known in addition to finding hydrogen in interstitial sites: dislocation mechanisms of hydrogen storage, micropores and microcracks, sorption on ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

open access: yesAdvanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.

Effective Catalytic Method of Diamantane Isomer Synthesis

open access: yesEurasian Chemico-Technological Journal, 2002
General principles of effect of the nature of metal-catalyst, carrier, solvent, method of preparation and temperature of catalyst reduction and other parameters (PH2, T, etc) on the process of hydrogenolysis of “binor-S” into pentacyclotetradecane have ...

Transitive bi-Lipschitz group actions and bi-Lipschitz parameterizations

open access: yes, 2012
We prove that Ahlfors 2-regular quasisymmetric images of the Euclidean plane are bi-Lipschitz images of the plane if and only if they are uniformly bi-Lipschitz homogeneous with respect to a group.

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

open access: yesAdvanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Sanksjoner, hybride trusler og skyggeflåten

open access: yesMagma
Sanksjoner er blitt et stadig viktigere virkemiddel i internasjonal politikk. Det har de siste årene vært en stor faglig diskusjon om effektene av sanksjoner. I denne artikkelen diskuterer vi hvordan sanksjoner rettet inn mot én type aktivitet eller ett

Risikofylt energihandel og EUs geopolitiske skifte

open access: yesMagma
Krigen i Ukraina er også en geopolitisk konflikt mellom vesten og Putins Russland. Da Russland annekterte Krim i 2014 skiftet forholdet mellom EU og Russland fra fred til sammensatt konflikt.
