Optoelectronic Characterization and Properties of Single-walled Carbon Nanotubes in a Liquid Dispersion Form

open access: yesInternational Journal of Technology, 2023
Carbon nanotubes (CNTs) are very promising nanodevices due to their extraordinary electrical, thermal, and optical properties. However, as-grown single-walled CNTs (SWCNTs) contain a mixture of semiconducting and metallic species with great features ...

Dispersion-Corrected Mean-Field Electronic Structure Methods.

open access: yesChemical Reviews, 2016
Mean-field electronic structure methods like Hartree-Fock, semilocal density functional approximations, or semiempirical molecular orbital (MO) theories do not account for long-range electron correlation (London dispersion interaction).

Justification of mixer parameters for flour components

open access: yesТехнічна інженерія, 2022
The need to provide the bakery and confectionery industries with new high-tech equipment that would ensure high-quality preparation of mixtures for the main processes in the production of flour semi-finished products with high-quality mixing of dosing ...

Realizing normal group-velocity dispersion in free space via angular dispersion [PDF]

open access: yes, 2021
It has long been thought that normal group-velocity dispersion (GVD) cannot be produced in free space via angular dispersion. Indeed, conventional diffractive or dispersive components such as gratings or prisms produce only anomalous GVD. We identify the conditions that must be fulfilled by the angular dispersion introduced into a plane-wave pulse to ...

Improved estimators for dispersion models with dispersion covariates

open access: yes, 2010
In this paper we discuss improved estimators for the regression and the dispersion parameters in an extended class of dispersion models (J{\o}rgensen, 1996).

Frequency-Dependent Schroeder Allpass Filters

open access: yesApplied Sciences, 2019
Since the introduction of feedforward−feedback comb allpass filters by Schroeder and Logan, its popularity has not diminished due to its computational efficiency and versatile applicability in artificial reverberation, decorrelation, and dispersive

Experimental determination and mathematical modelling of residence time distributions by using pieces of urban art

open access: yesFrontiers in Chemical Engineering, 2022
Residence time distribution (RTD) has a very high impact on the performance of a chemical reactor. The development of new reactor and catalyst structures has increased the importance of deep knowledge in theories of RTDs and good experimental practice in

General relationships between consumer dispersal, resource dispersal and metacommunity diversity [PDF]

open access: yesEcol. Lett. 17, 175--184 (2014), 2014
One of the central questions of metacommunity theory is how dispersal of organisms affects species diversity. Here we show that the diversity-dispersal relationship should not be studied in isolation of other abiotic and biotic flows in the metacommunity.

Solitons in media with mixed, high-order dispersion and cubic nonlinearity [PDF]

open access: yes, 2022
Although most soliton research has traditionally considered dominant quadratic dispersion, the recent discovery of pure-quartic solitons has inspired analysis of soliton solutions with large higher orders of dispersion. Here we present analytic expressions for families of bright soliton solutions at arbitrary dispersion orders and practical methods to ...

Survey on Drosophila suzukii Natural Short-Term Dispersal Capacities Using the Mark−Release−Recapture Technique

open access: yesInsects, 2019
Spotted wing drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), has become a key pest for soft fruits and cherries in Europe in less than a decade since the first outbreak in 2007.
