Iridium(III) Carbene Complexes Featuring Either Metal‐to‐Ligand Charge Transfer (MLCT) or Through‐Space Charge Transfer (TSCT) Blue Luminescence

Angewandte Chemie, EarlyView.
Ir(III) complexes with contrasting MLCT or TSCT transition characters were synthesized, among which the TSCT emitter f‐ct13b gave PhOLED device with an EQEmax of 22.2% and CIExy of (0.155, 0.120). Additionally, hyper‐OLED bearing another TSCT sensitizer, f‐ct13c and v‐DABNA terminal emitter, achieved a narrowband blue hyperphosphorescence with EQEmax ...

Effect of Temperature, Time, and Material Thickness on the Dehydration Process of Tomato

International Journal of Food Science, 2015
This study aimed to evaluate the effects of temperature, time, and thickness of tomatoes fruits during adiabatic drying process. Dehydration, a simple and inexpensive process compared to other conservation methods, is widely used in the food industry in ...

Magnetic Engine for the Single-Particle Landau Problem

Entropy, 2017
We study the effect of the degeneracy factor in the energy levels of the well-known Landau problem for a magnetic engine. The scheme of the cycle is composed of two adiabatic processes and two isomagnetic processes, driven by a quasi-static modulation of

Geometrical Representation of Sum Frequency Generation and Adiabatic Frequency Conversion [PDF]

, 2008
We present a geometrical representation of sum frequency generation process in the undepleted pump approximation. The analogy of such dynamics with the known optical Bloch equations is discussed. We use this analogy to present a novel technique for the achievement of both high efficiency and large bandwidth in a sum frequency conversion processes using

Electronic Structure of Kramers Nodal‐Line Semimetal YAuGe and Anomalous Hall Effect Induced by Magnetic Rare‐Earth Substitution

Advanced Science, EarlyView.
The rare‐earth intermetallics YAuGe is identified as a Kramers nodal‐line semimetal, a topological state inherent to non‐centrosymmetric achiral lattices. Magnetic rare‐earth substitution induces an anomalous Hall effect, highlighting the impact of time‐reversal symmetry breaking on topological electronic states and offering insights into designing the

Enantioselective Photochemical Generation of a Short‐Lived, Twisted Cycloheptenone Isomer: Catalytic Formation, Detection, and Consecutive Chemistry

Angewandte Chemie, EarlyView.
In a proof‐of‐concept study, it was for the first time shown that planar chiral trans‐cycloalk‐2‐enones, such as 2, can be formed enantioselectively from their cis‐isomers by triplet energy transfer from a chiral catalyst. Computational studies performed with cyclohept‐2‐enone and enone 1 provided invaluable insights into the mode of action of the ...

Speeding Up Classical and Quantum Adiabatic Processes: Implications for Work Functions and Heat Engine Designs [PDF]

arXiv, 2013
Adiabatic processes are important for studying the dynamics of a time-dependent system. Conventionally, the adiabatic processes can only be achieved by varying the system slowly. We speed up both classical and quantum adiabatic processes by adding control protocols.

On Adiabatic Processes at the Elementary Particle Level [PDF]

Journal of Physical Mathematics, 2016
Analysis of adiabatic processes at the elementary particle level and of the manner in which they correlate with the principle of conservation of energy, the principle of least action and entropy. Analysis of the initial and irreversible adiabatic acceleration sequence of newly created elementary particles and its relation to these principles ...

Revealing Physical Mechanisms of Spatial Pattern Formation and Switching in Ecosystems via Nonequilibrium Landscape and Flux

Advanced Science, EarlyView.
The universality of the landscape‐flux theory with the mode expansion method for analyzing spatial patterns is illustrated by applying it to vegetation patterns in semi‐arid ecosystems. The framework quantifies global dynamics and most probable transition pathways between ecosystem states under random forcing.
