In-situ growing carbon nanotubes reinforced highly heat dissipative three-dimensional aluminum framework composites.

The demand for lightweight heat dissipation design in highly miniaturized and portable electronic devices with high thermal density is becoming increasingly urgent. Herein, highly thermal conductive carbon nanotubes (CNTs) reinforced aluminum foam composites were prepared by catalyst chemical bath and subsequent in-situ growth approach. The dense CNTs show the intertwined structure features and construct high-speed channels near the surface of the skeletons for efficient thermal conduction, promoting the transport efficiency of heat flow.

3D MFA: An automated 3D Multi-Feature Attention based approach for spine segmentation using a multi-stage network pruning.

Spine segmentation poses significant challenges due to the complex anatomical structure of the spine and the variability in imaging modalities, which often results in unclear boundaries and overlaps with surrounding tissues. In this research, a novel 3D Multi-Feature Attention (MFA) model is proposed for spine segmentation. The standard MobileNetv3 is modified by adding the RCBAM (Reverse Convolution Block Attention Module) module, and FPP (Feature Pyramid Pooling) for feature enhancement.

Multi-omics analysis reveals the evolution, function, and regulatory mechanisms of SPF pheromones in Anurans.

Pheromones play a pivotal role in chemical communication across various taxa, with protein-based pheromones being particularly significant in amphibian courtship and reproduction. In this study, we investigate the Emei music frog (Nidirana daunchina), which utilizes both acoustic and chemical signals for communication. Base on a de novo assembled genome of a male Emei music frog, we identify substantial expansion in four pheromone-related gene families associated with chemical communication.

Ligand-Controlled Regioselective Alkoxycarbonylation of Nonfunctionalized Unsymmetric Internal Alkynes.

Pd-catalyzed alkoxycarbonylation of internal alkynes provides a straightforward access to α,β-disubstituted acrylic esters. Compared with the well-established regioselective alkoxycarbonylation of terminal alkynes, the regioselective hydrocarboxylation of non-functionalized unsymmetric internal alkynes was more challenging owing to the delicate differences of properties between the two substituents. Herein, by using either monophosphine ligand based on 2,3-dihydrobenzo[d][1,3]oxaphosphole motif or bidentate ligand Ph-Phox, the regioselective alkoxycarbonylations of aryl-aryl, aryl-alkyl and alkyl-alkyl disubstituted alkynes were achieved, giving a diversity of trisubstituted α,β-unsaturated carboxylic esters with moderate to excellent yields and high regioselectivity.

Effect of long-term exposure to non-biodegradable and biodegradable microplastics in continuous anoxic/aerobic bioreactors: Nitrogen removal performance, microbial communities and functional gene responses.

The environmental hazards caused by microplastics (MPs) have received widespread attention, but the effects of non-biodegradable and biodegradable MPs of long-term presence on continuously operating sewage treatment bioreactors are not well known. In this study, we investigated the effect of a representative non-biodegradable MP, polyethylene terephthalate (PET), and a biodegradable MP, polylactic acid (PLA), on the nitrogen removal performance of conventional anoxic/aerobic (A/O) process. The NH-N removal efficiencies were suppressed to 91.

Deciphering the hepatitis E virus ORF1: Functional domains, protein processing, and patient-derived mutations.

Hepatitis E virus (HEV) is a major cause of acute and chronic hepatitis in humans. The HEV open reading frames (ORF1) encodes a large non-structural protein essential for viral replication, which contains several functional domains, including helicase and RNA-dependent RNA polymerase. A confusing aspect is that, while RNA viruses typically encode large polyproteins that rely on their enzymatic activity for processing into functional units, the processing of the ORF1 protein and the mechanisms involved remain unclear.

Feedback-induced phase separation of hollow condensates to create biomimetic membraneless compartments.

Intracellular macromolecules have the ability to form membraneless compartments, such as vacuoles and hollow condensates, through liquid-liquid phase separation (LLPS) in order to adapt to changes in their environment. The development of artificial non-homogeneous compartments, such as multiphase hollow or multicavity condensates, has gained significant attention due to their potential to uncover the mechanisms underlying the formation of artificial condensates and biomolecular condensates. However, the complexity of design and construction has hindered progress, particularly in creating dynamic non-homogeneous compartments.
