Scalable growth of vertical graphene nanosheets by thermal chemical vapor deposition.

Vertical graphene nanosheets (VGSs) are a kind of graphene materials, which retain the inherent advantages of graphene and effectively overcome the stacking bottleneck displayed by traditional graphene. The scalable production of VGSs may help the development of devices such as field-effect transistors, sensors, biomedical materials, electrochemical energy storage, thermal conductive materials and catalyst supports. The thermal chemical vapor deposition (CVD) approach has become a mature, efficient and highly valuable industrial strategy for VGSs fabrication.

Simulation and experiment research on heat treatment of micro and nano BN particles modified casting aluminum copper alloys.

The heat treatment process is a key technology to improve the performance of cast aluminum-copper alloys with micro-nano boron nitride (BN) particles, but its strengthening mechanism still needs to be studied. Orthogonal tests were used to carry out heat treatment experiments on aluminum matrix ceramic composites prepared by adding different contents of micro-nano BN particles. Then, a crystal model was established, and the heat treatment process was simulated by the molecular dynamics (MD) method.

Dynamics of measurable residual disease for risk stratification and guiding allogeneic transplant in acute myeloid leukaemia patients with myelodysplasia-related mutations in first remission.

Accurate classification and risk prediction are critical for therapeutic decision-making in patients with acute myeloid leukaemia (AML).

However, their prognostic value in de novo AML remains controversial.

Multiscale Simulation of Laser-Based Direct Energy Deposition (DED-LB/M) Using Powder Feedstock for Surface Repair of Aluminum Alloy.

Laser-based direct energy deposition (DED-LB/M) has been a promising option for the surface repair of structural aluminum alloys due to the advantages it offers, including a small heat-affected zone, high forming accuracy, and adjustable deposition materials. However, the unequal powder particle size during powder-based DED-LB/M can cause unstable flow and an uneven material flow rate per unit of time, resulting in defects such as pores, uneven deposition layers, and cracks. This paper presents a multiscale, multiphysics numerical model to investigate the underlying mechanism during the powder-based DED-LB/M surface repair process.

Influence of nano-BN inclusion and mechanism involved on aluminium-copper alloy.

Taking advantage of the high specific surface area of the nanoparticles, boron nitride (BN) nanoparticles were incorporated into the semi-solidified aluminium-copper alloy Al-5Cu-Mn (ZL201) system during the casting process, and its properties and enhancement mechanism were studied. The results shown that the BN in the new composite material is more uniformly distributed in the second phase (AlCu), which can promote grain refinement and enhance the bonding with the aluminium-based interface, and the formation of stable phases such as AlB, AlN, CuN, etc. makes the tensile strength and hardness of the material to be significantly improved (8.

Adipose mesenchymal stem cell-derived exosomes promote skin wound healing in diabetic mice by regulating epidermal autophagy.

Background: Adipose mesenchymal stem cell-derived exosomes (ADSC-Exos) have great potential in the field of tissue repair and regenerative medicine, particularly in cases of refractory diabetic wounds. Interestingly, autophagy plays a role in wound healing, and recent research has demonstrated that exosomes are closely associated with intracellular autophagy in biogenesis and molecular signaling mechanisms. Therefore, this study aimed to investigate whether ADSC-Exos promote the repair of diabetic wounds by regulating autophagy to provide a new method and theoretical basis for the treatment of diabetic wounds.

This meta-analysis aims to compare the clinical outcomes of HHR and Laparoscopic Hernia Repair (LHR) in the management of IVH.

Targeted inhibition of Wnt signaling with a Clostridioides difficile toxin B fragment suppresses breast cancer tumor growth.

Wnt signaling pathways are transmitted via 10 homologous frizzled receptors (FZD1-10) in humans. Reagents broadly inhibiting Wnt signaling pathways reduce growth and metastasis of many tumors, but their therapeutic development has been hampered by the side effect. Inhibitors targeting specific Wnt-FZD pair(s) enriched in cancer cells may reduce side effect, but the therapeutic effect of narrow-spectrum Wnt-FZD inhibitors remains to be established in vivo.
