Article Abstract
The electron localization is considered as a promising approach to optimize electromagnetic waves (EMW) dissipation. However, it is still difficult to realize well-controlled electron localization and elucidate the related EMW loss mechanisms for current researches. In this study, a novel two-dimensional MXene (TiCT) nanosheet decorated with Ni nanoclusters (Ni-NC) system to construct an effective electron localization model based on electronic orbital structure is explored. Theoretical simulations and experimental results reveal that the metal-support interaction between Ni-NC and MXene disrupts symmetric electronic environments, leading to enhanced electron localization and dipole polarization. Additionally, Ni-NC generate a strong interfacial electric field, strengthening heterointerface interactions and promoting interfacial polarization. As a result, the optimized material achieves an exceptional reflection loss (RL) of - 54 dB and a broad effective absorption bandwidth of 6.8 GHz. This study offers critical insights into the in-depth relationship between electron localization and EMW dissipation, providing a pathway for electron localization engineering in functional materials such as semiconductors, spintronics, and catalysis.

Conventional acid-catalyzed acetalization faces significant challenges in catalyst recovery and poses environmental concerns. Herein, we develop a CeO-supported Pd single-atom catalyst (Pd/CeO) that eliminates the reliance on liquid acids by creating a localized H-rich microenvironment through heterolytic H activation. X-ray absorption near-edge structure and extended X-ray absorption fine structure analyses confirm the atomic dispersion of Pd via Pd-O-Ce coordination, while density functional theory (DFT) calculations reveal strong metal-support interactions (SMSI) that facilitate electron transfer from CeO oxygen to Pd, downshifting the Pd d-band center and optimizing H activation.

Purpose: This study investigates the antibacterial and anticancer activity of previously reported iron oxide (FeO)-based nanoparticles (NPs) conjugated with chlorin e6 and folic acid (FCF) in photodynamic therapy (PDT) using a human bladder cancer (BC) (T-24) cell line and three bacterial strains.
Method: To investigate the potential applicability of the synthesized NPs as therapeutic agents for image-based photodynamic BC therapy, their photodynamic anticancer activity was analyzed and the mechanisms of cell death in T-24 cells treated with these NPs were assessed qualitatively and quantitatively through atomic absorption spectroscopy, fluorescence imaging, and transmission electron microscopy.
Results: The effective localization of FCF NPs in T-24 cells were confirmed, validating their excellent cellular fluorescence and magnetic resonance imaging capabilities.

The representation of the electronic structure of benzene is important for understanding the properties of planar and monocyclic organic carbon compounds. Resonant Kekulé and conjugated structures based on localized and delocalized electronic theories, respectively, can be used to depict the ground state of benzene; however, depictions of its electrons vibrating in the excited states remain to be clarified. This paper presents a novel algorithm for exploring the three lowest lying vertically singlet excited states of benzene, focusing on the electronic excitations between occupied π and unoccupied π* orbitals.

Purpose Of Review: Obesity is a global health concern and is intricately linked to cardiovascular disease and metabolic disorders. While its causal association with chronic kidney disease (CKD) has also been recognized, this entity has not been discussed extensively. Obesity-related glomerulopathy (ORG) is pathologically a secondary form of focal segmental glomerulosclerosis (FSGS), which typically presents clinically with subnephrotic proteinuria, and histopathologically as glomerulomegaly, and the perihilar variant of FSGS.
