Progress in Flexible Perovskite Solar Cells: Paving the Way for Scalable Manufacturing

Advanced Materials Technologies, EarlyView.
Perovskite solar cells (PSCs) are well positioned for a successful market uptake. This is due to an unprecedented improvement of their efficiency and stability since the first report in 2009. In this review paper, the building blocks for the scalable manufacturing and future commercialization of flexible PSCs and their pathway to impact will be ...

Nonequilibrium Thermodynamics and Lifetime of Physical Systems [PDF]

arXiv, 2004
To describe the nonequilibrium states of a system we introduce a new thermodynamic parameter - the lifetime of a system. The statistical distributions which can be obtained out of the mesoscopic description characterizing the behaviour of a system by specifying the stochastic processes are written down.

Microscopic rheological models and extended irreversible thermodynamics

Applied Mathematics Letters, 1991
AbstractThe expressions of the constitutive equations of dilute polymer solutions, as predicted by the main microscopic rheological models, are shown to be in agreement with these derived from extended irreversible thermodynamics. Accord between the thermodynamic and Boltzmann microscopic expressions of entropy is also completed for steady state flows.

From the Bulk to the Nanoscale: Strong Evolution in the Structure and Chiroptical Properties of Chiral Halide Double Perovskites

Advanced Optical Materials, EarlyView.
A complete series of bromide‐based and iodide‐based 2D chiral double perovskites has been structurally characterized and their chiroptical properties investigated to reveal the effect of both polymorphism and nature of the halide anions in the circular dichroism of the thin films.

Purinylidene‐Based Iridium(III) Phosphors for Efficient Purple Phosphorescence and Organic Light‐Emitting Devices

Advanced Photonics Research, EarlyView.
A family of purinylidene based Ir(III) emitters, namely, f‐ct2a–d, are synthesized and utilized as both dopants and sensitizers in the construction of efficient purple to deep‐blue organic light‐emitting diode devices. It is very challenging to achieve highly efficient and low roll‐off purple to deep‐blue organic light‐emitting diodes (OLEDs) due to ...

Distinguished rheological models in the framework of a thermodynamical internal variable theory

, 2014
We present and analyze a thermodynamical theory of rheology with single internal variable. The universality of the model is ensured as long as the mesoscopic and/or microscopic background processes satisfy the applied thermodynamical principles, which ...

Stochastic Processes and Thermodynamics on Curved Spaces [PDF]

arXiv, 2000
Our approach views the thermodynamics and kinetics in general relativity and extended gravitational theories (with generic local anisotropy) from the perspective of the theory of stochastic differential equations on curved spaces. Nonequilibrium and irreversible processes in black hole thermodynamics are considered.

Gram‐Scale Photocatalysis with a Stable and Recyclable Chromium(III) Photocatalyst in Acetonitrile and in Water

Advanced Synthesis &Catalysis, Accepted Article.
The use of stable photosensitizers made on a multigram‐scale from cheap and available starting materials offers an extraordinary opportunity to translate small‐scale proof‐of‐concept photoreactions to widespread applications in non‐specialized laboratories, thereby promoting the implementation of light‐driven syntheses.

Theories and heat pulse experiments of non-Fourier heat conduction

, 2015
The experimental basis and theoretical background of non-Fourier heat conduction is shortly reviewed from the point of view of non-equilibrium thermodynamics. The performance of different theories is compared in case of heat pulse experiments.Comment: 12
