Although research on the preparation of metal oxides and other materials for various applications increases exponentially, it is more important to Pants understand the need for eco-friendly methods of preparation to preserve the environment.Most of the methods available today are expensive, environmentally harmful, and inefficient with respect to m
The microstructures and phase formations of Ti20Zr15Hf15Ni35Cu15 high entropy shape memory alloy (HESMA) under different aging conditions were investigated in this study.At aging temperatures below 500 °C, a large amount of the H-phase formed, and the martensitic transformation temperatures were suppressed due to the strain field around Ophthalmi
About one year ago, we wrote about how the COVID-19 pandemic was unfolding worldwide and started to impact our personal and professional lives (1).Little did we know that, one year later, more than 2.5 million people would have died, with the highest death tolls in Europe, North America, and Latin America (2).Whereas in many countries, life expecta
Spontaneous spinal epidural hematoma (SEH) is an uncommon and emergency condition leading to spinal cord compression.Early diagnosis can be achieved by magnetic resonance imaging (MRI) or Flax computed tomography, but preferably MRI.Surgical decompression is urgent and can relieve neurologic deficits.A 27-year-old man presented to the emergency dep
The key of success of extraintestinal pathogenic Escherichia coli (ExPEC) to colonize niches outside the intestinal tract and to establish infection is the coordinated action of numerous virulence and fitness factors.The so-called high-pathogenicity island (HPI), responsible for synthesis, secretion and uptake of the siderophore yersiniabactin, pro
