In this research work effect of embedment of multiwall carbon nanotubes (MWCNTs) on the physical and mechanical properties of medium density fiberboard (MDF) have been investigated. The MWCNTs were embedded in urea formaldehyde resin (UF) at 0, 1.5%, 3% and 5% concentrations by weight for the manufacturing of nano-MDF. The addition of these nanoparticles enhanced thermal conductivity by 24.2% reduced curing time by 20% and controlled formaldehyde emission by 59.4%. The internal bonding (I.B), modulus elasticity (MOE), modulus of rupture (MOR), thickness swelling (Ts) and water absorption (WA) properties were improved significantly by 21.15%, 30.2%, 28.3%, 44.8% and 29% respectively as compared to controlled MDF.

High-fidelity biosignal monitoring is essential for daily health tracking and the diagnosis of chronic diseases. However, developing bioelectrodes capable of withstanding repeated use and mechanical deformation on wet tissue surfaces remains a significant challenge. Here, we present a robust and ultrathin bioelectrode (RUB), featuring a mechanically heterogeneous architecture and a thickness of ∼3 μm.

The purpose of this study was to evaluate the evolution of jump and sprint force-production capacities with maturation in young soccer players. One hundred sixteen young elite male soccer players aged 11-17 years were assigned to six different groups according to their maturity status. The force-velocity (F-V) profiles in jumping and sprinting performances were compared among groups.

Zirconium disilicide (ZrSi) ceramics have excellent physical and chemical properties and are employed in aerospace, energy, and chemical industries. Currently, the preparation and properties of ZrSi ceramics have been less studied. To comprehensively study the characteristics of ZrSi ceramics, in this study, dense bulk ZrSi ceramic samples are successfully prepared by the high-pressure-high-temperature (HPHT) sintering technique.

The diagnosis of hemolysis is still based on straightforward biochemical parameters: haptoglobin (the most sensitive), lactate dehydrogenase (LDH), and unconjugated bilirubin. Anemia is not always present. Reticulocyte counts typically exceed 120×10/L, except in cases of associated vitamin deficiency or during the very early phase of acute hemolysis.

Background: Early diagnosis of cholangiocarcinoma (CCA) remains challenging, but liquid biopsy is emerging as a promising detection strategy. Here, we identified a novel bile biomarker for CCA and developed an optic fiber biosensor integrated with digestive endoscopy for real-time diagnosis in vivo.
Methods: A total of 583 subjects and two proteomic analyses were used to screen and validate biomarkers for CCA, and then the corresponding antibodies were generated to construct a surface plasmon resonance (SPR)-based optic fiber biosensor.
