Three-dimensional ordered mesoporous CoO was prepared by nanocasting method with porous silicon KIT-6 as the hard template and firstly used to activate peroxymonosulfate for the degradation of rhodamine B. The structural properties were characterized by BET, H-TEM, XRD, XPS, FT-IR. The results showed that three-dimensional ordered mesoporous CoO presented far superior catalytic activity over conventional nanoscale CoO due to its abundant space mesoporous channel structure and the large specific surface areas. Higher catalyst dosage and higher peroxymonosulfate concentration favored the decolorization of rhodamine B. The removal of rhodamine B could be accelerated in the presence of Cl and HPO; however, the decolorization of rhodamine B would be inhibited in the presence of NO, SO and HCO. Sulfate radicals were identified as the dominant active species for the decolorization of rhodamine B through radicals quenching experiments. Three-dimensional ordered mesoporous CoO showed excellent catalytic activity even after five consecutive cycles.

Hexagonal boron nitride (h-BN), with excellent thermal conductivity and insulation capability, has garnered significant attention in the field of electronic thermal management. However, the thermal conductivity of the h-BN-enhanced polymer composite material is far from that expected because of the insurmountable interfacial thermal resistance. In order to realize the high thermal conductivity of polymer composite thermal interface materials, herein, an in situ exfoliation method has been employed to prepare a boron nitride nanosheet-graphene (BNNS-Gr) hybrid filler.

The spatial organization of the genome plays a critical role in regulating gene expression, cellular differentiation, and genome stability. This review provides an in-depth examination of the methodologies, computational tools, and frameworks developed to map the three-dimensional (3D) architecture of the genome, focusing on both ligation-based and ligation-free techniques. We also explore the limitations of these methods, including biases introduced by restriction enzyme digestion and ligation inefficiencies, and compare them to more recent ligation-free approaches such as Genome Architecture Mapping (GAM) and Split-Pool Recognition of Interactions by Tag Extension (SPRITE).

Atrial fibrillation (AF) is the most prevalent clinical arrhythmia, posing significant mortality and morbidity challenges. Outcomes of current catheter ablation treatment strategies are suboptimal, highlighting the need for innovative approaches. A major obstacle lies in the inability to comprehensively assess both structural and functional remodelling in AF.

Objectives: The current research delves into the use of 3D geometric morphometric for assessing shifts in maturity within both the proximal and distal humeral metaphyses. It mainly focuses on establishing correlations between these shifts and the shape changes observed in the corresponding epiphyses established through radiographic imaging.
Material And Methods: The total sample comprises 120 right-side proximal humeral metaphyses and 91 right-side distal humeral metaphyses.

Crystalline porous materials, known for their ordered structures, hold promise for efficient hydroxide conductivity in alkaline fuel cells with limited ionic densities. However, the rigid cross-linking of porous materials precludes their processing into membranes, while composite membranes diminish materials' conductivity advantage due to the interrupted phases. Here, we report a self-standing three-dimensional covalent organic framework (3D COF) membrane with efficient OH-transport through its interconnected 3D ionic nanochannels.
