Adiabatic transport in nanostructures

open access: yes, 2002
A confined system of non-interacting electrons, subject to the combined effect of a time-dependent potential and different external chemical-potentials, is considered.

Investigating the effect of some insecticides on Pulvinaria aurantii Ckll. and its predator, Cryptolaemus montrouzieri Mulsant [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2019
The orange pulvinaria scale, Pulvinaria aurantii Ckll. is the most important scale of citrus in the northern Iran. The lethal effects of chlorpyrifos, pyripropoxyfen, acetamiprid and palazin, alone and in combination with emulsifying oil, were evaluated ...

Chemical Potential Dependence of Chiral Quark Condensate in Dyson-Schwinger Equation Approach of QCD

open access: yes, 2006
We propose a chemical potential dependent effective gluon propagator and study the chiral quark condensate in strongly interacting matter in the framework of Dyson-Schwinger equation approach.

Effective Chemical Processes in Porous Media [PDF]

open access: yesMathematical Models and Methods in Applied Sciences, 2003
In the book by Hornung, Chap. 6, the author proposes a homogenization strategy for the effective behavior of some chemical processes involving adsorption and reactions arising in porous media. Rigorous proofs of the convergence results are given in the case of linear adsorption rates and linear chemical reactions. The author leaves as an open question

Photon Production from a Quark-Gluon-Plasma at Finite Baryon Chemical Potential

open access: yes, 2012
We compute the photon production of a QCD plasma at leading order in the strong coupling with a finite baryon chemical potential. Our approach starts from the real time formalism of finite temperature field theory.

Efficient hydrogen production through the chemical looping redox cycle of YSZ supported iron oxides

open access: yesGreen Energy & Environment, 2021
The chemical looping process, where an oxygen carrier is reduced and oxidized in a cyclic manner, offers a promising option for hydrogen production through splitting water because of the much higher water splitting efficiency than solar electrocatalytic ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Beyond Structural Stabilization of Highly‐Textured AlN Thin Films: The Role of Chemical Effects

open access: yesAdvanced Materials Interfaces
The crystalline quality and degree of c‐axis orientation of hexagonal AlN thin films correlate directly with their functional properties. Therefore, achieving AlN thin films of high crystalline quality and texture is of extraordinary importance for many ...
