First principle study of transition metals codoped MoS2 as a gas sensor for the detection of NO and NO2 gases
(
Elsevier B.V.
, 2021 , Article)
Exposure to nitrogen oxides (NOx) has been reported to seriously affect the respiratory systems. More precisely, breathing NOx may lead to the appearance of asthma symptoms, and may also result in the infection with asthma ...
Conformal Invariants in Simply Connected Domains
(
Springer Link
, 2020 , Article)
This paper studies the numerical computation of several conformal invariants of simply connected domains in the complex plane including, the hyperbolic distance, the reduced modulus, the harmonic measure, and the modulus ...
Co-doped zigzag graphene nanoribbon based gas sensor for sensitive detection of H2S: DFT study
(
Academic Press
, 2021 , Article)
In this work, we present a highly sensitive gas sensor for the detection of poisonous hydrogen sulfide gas (H2S) based on copper and zinc co-doped zigzag graphene nanoribbon (Cu/Zn-ZGNR). The electronic properties as well ...
Condenser capacity and hyperbolic perimeterImage 1
(
Elsevier
, 2021 , Article)
We study the conformal capacity by using novel computational algorithms based on implementations of the fast multipole method, and analytic techniques. Especially, we apply domain functionals to study the capacities of ...
Computational study of metal doped graphene nanoribbon as a potential platform for detection of H2S
(
Elsevier Ltd
, 2021 , Article)
Theoretical investigation for detection of hydrogen sulfide (H2S) gas using hydrogen/nitrogen-terminated armchair graphene nanoribbon (HAGNR and NAGNR) doped with Pt is presented in this study. The investigation was ...
Numerical computation of the capacity of generalized condensers
(
Elsevier
, 2020 , Article)
We present a boundary integral method for numerical computation of the capacity of generalized condensers. The presented method applies to a wide variety of generalized condenser geometry including the cases when the plates ...
Condenser capacity and hyperbolic diameter
(
Elsevier
, 2021 , Article)
Given a compact connected set E in the unit disk B2, we give a new upper bound for the conformal capacity of the condenser (B2,E) in terms of the hyperbolic diameter t of E. Moreover, for t>0, we construct a set of hyperbolic ...
Students Impression About Using Mobile Phones in Classroom
(
Kassel University Press GmbH
, 2020 , Article)
Mobile phones are widely used by university students and there is a controversial topic whether students should be able to use them freely during lectures. A survey was distributed seeking student opinions on using mobile ...
An efficient image encryption scheme based on fractal Tromino and Chebyshev polynomial
(
Springer International Publishing
, 2021 , Article)
The security of digital content during transmission and storage through insecure communication links and databases is a challenging issue in today's world. In this article, an encryption scheme based on fractal Tromino and ...
