Article Synopsis
- This study focuses on the properties of Inconel 718/Ti6Al4V multi-material samples with a Cu and Nb interlayer produced using selective laser melting (SLM).
- It investigates the microstructure, chemical composition, phase composition, and hardness, revealing island macro-segregation at interfacial zones and distinct transitions in chemical composition.
- The findings indicate that while no new phases were formed, there were notable changes in microhardness and the ultimate tensile strength of the samples was found to be 910 MPa.
Multi-material can have functional properties, which are not typical for the materials of which they are composed (for instance, shape-changing effect). This can be used in robotics, micromachines, aerospace, and other fields. In this work, the 316L/FeNi36 multi-material produced by selective laser melting was investigated.

- Bostrycoidin, a pigment from fungi, has pharmacological significance and indicates Fusarium infections in crops and soils.
- Researchers used density functional theory (DFT) to investigate the molecular structure and properties of bostrycoidin, analyzing its most stable geometry and energy levels of various conformers.
- The study successfully modeled the vibrational and electronic absorption spectra, with the calculated longest-wavelength transition aligning well with experimental results at approximately 498 nm.
The conversion of metal-organic frameworks (MOFs) into advanced functional materials offers a promising route for producing unique nanomaterials. MOF-derived systems have the potential to overcome the drawbacks of MOFs, such as low electrical conductivity and poor structural stability, which have hindered their real-world applications in certain cases. In this study, laser scribing was used for pyrolysis of a Cu-based MOF ([Cu{1,4-CH(COO)}(4,4'-bipy)]) to synthesize a Cu-CuO@C composite on the surface of a screen-printed electrode (SPE).

The aim of the study was to study the risk factors for VTE in elderly and senile patients with diabetes mellitus who are scheduled for spinal surgery. A single-center retrospective study included 119 elderly and senile patients (64 men, 55 women, mean age 74,2±6,5 years) who underwent various surgical interventions on the spinal column.
