Azo dyes, prevalent in various industries, including textile dyeing, food, and cosmetics, pose significant environmental and health risks due to their chemical stability and toxicity. This study introduces the synthesis and application of a copper hydrogen-π-bonded benzoate framework (Cu-HBF) and its derived marigold flower-like copper oxide (MFL-CuO) in a synergetic adsorption-photocatalytic process for efficiently removing cationic azo dyes from water, specifically crystal violet (CV), methylene blue (MB), and rhodamine B (RhB). The Cu-HBF, previously available only in single crystal form, is prepared here as a crystalline powder for the first time, using a low-cost and facile procedure, allowing its application as an adsorbent and also serving as a precursor for synthesizing well-structured copper oxide (MFL-CuO).

The quantum mechanics/molecular mechanics (QM/MM) method is a powerful approach for investigating solid surfaces in contact with various types of media, since it allows for flexible modeling of complex interfaces while maintaining an all-atom representation. The mean-field QM/MM method is an average reaction field model within the QM/MM framework. The method addresses the challenges associated with the statistical sampling of interfacial atomic configurations of a medium and enables efficient calculation of free energies.

Magnetic heat capacity measurements of a high-quality single crystal of the dipole-octupole pyrochlore Ce_{2}Hf_{2}O_{7} down to a temperature of T=0.02 K are reported. These show a two-peaked structure, with a Schottky-like peak at T_{1}∼0.

Photonic crystals are artificial materials characterized by a photonic band structure that governs the propagation of light waves. The photonic gap was originally introduced to inhibit spontaneous emission and facilitate photon localization. In this essay, I will highlight how, despite the established understanding of photonic crystals, they remain highly relevant today.

Background And Objective: Male fertility assessment through sperm morphology analysis remains a critical component of reproductive health evaluation, as abnormal sperm morphology is strongly correlated with reduced fertility rates and poor assisted reproductive technology outcomes. Traditional manual analysis performed by embryologists is time-intensive, subjective, and prone to significant inter-observer variability, with studies reporting up to 40% disagreement between expert evaluators. This research presents a novel deep learning framework combining Convolutional Block Attention Module (CBAM) with ResNet50 architecture and advanced deep feature engineering (DFE) techniques for automated, objective sperm morphology classification.
