Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Study on Frequency Characteristics of Rotor Systems for Fault Detection Using Variational Mode Decomposition

International Journal of Rotating Machinery, 2017
Due to the complicated structure, vibration signal of rotating machinery is multicomponent with nonstationary and nonlinear features, so it is difficult to diagnose faults effectively.

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency

Advanced Materials, EarlyView.
This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.

A TC-Based Multicomponent LFM Signal Characterization Method Under Impulsive Noise and Its Application

IET Signal Processing
The burst-like and high-amplitude characteristics of impulsive noise, which markedly differ from those of Gaussian noise, render methods based on the Gaussian assumption unable to accurately characterize signals under impulsive noise.

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids

Advanced Materials, EarlyView.
Strong dipole–dipole interactions give rise to an emergent polar smectic phase with spontaneous chiral symmetry breaking. This resulting polar heliconical smectic superstructure enables novel functionalities in polar fluids, such as color modulation driven by electric field strength and frequency, as well as second‐harmonic generation amplification ...

Description of new putative multicomponent courtship signal for mate recognition in Rachoviscus crassiceps (Characiformes: Acestrorhamphidae) [PDF]

Neotropical Ichthyology
Males of Rachoviscus crassiceps have two small longitudinal black marks on pectoral-fin rays associated to hard and thick tissues that develop in the dorsal surface of the first and second branched pectoral-fin rays, covered dorsally with pheromone ...

Electrical Resistivity Change Upon Crystallization as a Robust Descriptor for Metallic Glass Forming Ability

Advanced Materials, EarlyView.
Electrical resistivity change upon annealing is introduced as a rapid descriptor for identifying high glass‐forming ability in metallic glasses. High‐throughput combinatorial thin‐film libraries reveal that compositions exhibiting small resistivity changes correspond to sluggish crystallization behavior and known bulk metallic glass regions, enabling ...
