Summary: The study found that a Si modified steel SIMP exhibited better oxidation resistance compared to T91 in 500 degrees C steam with a flow rate of 5 m/s, and the oxidation rate was significantly enhanced at relatively low dissolved oxygen levels. This suggested that not only alloy composition and dissolved oxygen, but also the flow rate, played important roles in the corrosion behavior of ferritic-martensitic steels.

Summary: Electroanalytical determination of chlorides in molten salts lacks the necessary accuracy for nuclear material monitoring, as observed in the studies on samarium trichloride. The formation of a poorly soluble and relatively stable oxychloride during the studies was identified as the cause of the accuracy loss. This study investigates the spectroscopic and electrochemical properties of synthesized samarium oxychloride in relation to the pyrochemical reprocessing of used nuclear fuel.

Summary: Glycation of proteins can lead to structural alteration, functional deprivation, and generation of advanced glycation end products (AGEs). Reactive oxygen species (ROS) generated during glucose autoxidation induce glycoxidation of glycated proteins, resulting in the formation of aldehyde and/or ketone groups containing dicarbonyls or reactive carbonyl species (RCS). RCS further react non-enzymatically, exacerbating oxidative, carbonyl, and glycative stress in the physiological system. This study focuses on the glycoxidative damage suffered by immunoglobulin G (IgG) and fibrinogen proteins induced by glyoxal (GO) and explores the resulting structural alterations and quantifies various biochemical markers. The results suggest that AGEs formation during GO-mediated glycation of IgG and fibrinogen could disrupt normal physiology and play a significant role in the pathogenesis of diabetes-associated secondary complications.

Summary: In this study, a flexible piezoelectric nanogenerator with tunable output power using a PVDF-CFO nanocomposite film was prepared. By incorporating ferromagnetic CFO nanoparticles into the PVDF matrix, the ferroelectric beta phase fraction of PVDF was enhanced, providing magnetic tunability to the PENG device. The output power of the PENG increased with the application of an external magnetic field, attributed to the decrease in resistance of the nanocomposite film.

Summary: In this study, zinc indium sulfide coupled polyaniline (ZnIn2S4/PANI) nanocomposites were synthesized using a chemisorption method. The nanocomposites exhibited significant enhancement in photo-catalytic and photoelectrochemical (PEC) water splitting activity under visible light illumination. The improvement in photodegradation and PEC water splitting activity is attributed to extended visible light absorption, synergistic effect of PANI, and the formation of a type-II heterojunction, which facilitates charge separation and faster transfer efficiency of photogenerated charge carriers.

The H-ZnIn2S4/g-C3N4 nanocomposites exhibited a 1.9 times higher photoelectrochemical performance than H-ZnIn2S4. The improved performance can be attributed to the formation of a type-II heterojunction, which enhances the separation and transfer of photogenerated charge carriers.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.
