Cerium-based conversion coatings were formed on AZ91D magnesium alloy by immersion of the substrate in solutions containing Ce(NO3)3, H2O2 and ascorbic acid (HAsc). The characterisation of the films was performed by elec...

Bone plays a vital role in providing the structural framework of the human body and protecting internal organs. Porous scaffolds that promote cell proliferation is necessary to artificially create bone by tissue engineer...

The paper studied the elemental composition of lead alloys of appendage stamps and seals of Middle Ages, and the influence of impurity elements in the alloy and conditions for long-term storage of monuments on the course...

The kinetics of diffusion of interstitial elements on the example of diffusion saturation with boron and silicon iron- carbon matrix ( - iron) was considered . The layers of intermetallic Fe - B - Si are formed and grow ...

Upconversion nanoparticles (UCNs) find application in nanomedicine as biolabels to identify cancer cells. In this work, Y2O3: Er3+/ Yb3+ and Gd2O3: Er3+/ Yb3+ systems were fabricated by combustion synthesis (CS) and sol-...
