Regulating secondary phase of Rb‐based aggregates for efficient and stable perovskite solar cells

FlexMat, EarlyView.
By introducing RbAc into the precursor solution, the crystallization pathway is optimized, excessive lead iodide is eliminated, grain size increases, and defects are passivated in the perovskite films. The obtained perovskite devices exhibit improved power conversion efficiency and operational stability. Abstract Passivating defects in perovskite films

Flexible organic electrodes for batteries: A mini‐review

FlexMat, EarlyView.
This review surveys progress and challenges in flexible organic electrodes (FOEs) for batteries. We discuss their fabrication methods, electrochemical performance, and mechanical tolerance, covering both planar and fibrous architectures, and compare them with flexible inorganic and rigid organic electrodes.

High‐Fidelity Synthetic Raman Spectra Generation for Sinter Basicity Prediction Using β$$ \beta $$‐Variational Autoencoders

Journal of Raman Spectroscopy, EarlyView.
A β$$ \beta $$‐variational autoencoder with β$$ \beta $$ = 0.1 generates high‐fidelity synthetic Raman spectra of industrial sinter with a 16‐fold improvement in spectral fidelity over SMOTE‐based augmentation (KL divergence: 0.0075 vs. 0.121), enabling reliable basicity prediction (R2 = 0.83) from limited labeled datasets.

Raman Spectroscopy and Generative Variational Autoencoders for Metallurgical Coke Quality Prediction

Journal of Raman Spectroscopy, EarlyView.
An integrated soft sensor framework combining standardized Raman spectroscopy, synergy‐vector feature selection, variational autoencoder‐based data augmentation, and regression models (kNN, PLS, and SVR) predicts metallurgical coke quality (CSR and DI).

A Boothby–Wang Construction in Generalized Contact Geometry

Mathematische Nachrichten, EarlyView.
ABSTRACT We establish a generalized analogue of the Boothby–Wang theorem in generalized contact geometry, along with related results. We present a general method for constructing examples of generalized contact structures that are not of Poon–Wade type, and even examples that fail to be generalized contact structures.

Composite Fibers of Hydroxypropyl Cellulose and Alginate Spun From Aqueous Solution: Crosslinking Effects on Water Absorption and Mechanical Properties

Polymer Engineering &Science, EarlyView.
Alginate‐HPC composite fibers spun via CaCl2‐induced gelation process. Fiber diameter ranges from 100 to 200 μm after air drying. Higher alginate boosts water absorption in dried fibers. HPC selectively diffuses out when fibers are soaked in water. Crosslinking with hexamethylene diisocyanate improves mechanical strength.

Enhanced inverse Faraday effect and time-dependent thermo-transmission in gold nanodisks

Nanophotonics
Nonmagnetic media can be magnetized by light via processes referred to as an inverse Faraday effect (IFE). With nonmagnetic metal nanostructures, the IFE is dominated by the presence of light-induced solenoidal surface currents or plasmons with orbital ...
