An exploratory investigation into the behavior of materials with desirable electric properties resulted in the discovery of a structural phase of two-dimensional (2D) materials. The new family of materials are electrides, wherein electrons occupy a space usually reserved for atoms or ions instead of orbiting the nucleus of an atom or ion. The stable, low-energy, tunable materials could have potential applications in nanotechnologies.
Alzheimer s & Dementia: The Journal of the Alzheimer s Association. We found that all causes of dementia are risk factors for severity and death in COVID-19 and that these risks are more pronounced for Alzheimer s patients,
Sérgio Verjovski-Almeida, principal investigator for the project and a professor at USP s Chemistry Institute, told
Agência FAPESP.
Dementia had already been identified as a risk factor for COVID-19, alongside other comorbidities, such as cardiovascular and respiratory diseases, high blood pressure, diabetes, obesity, and cancer. One of the reasons is age: patients with dementia tend to be older, and many live in care homes where the risks of infection and viral transmission are greater.
Besides common symptoms such as fever, cough and respiratory distress, some children have an atypical form of COVID-19 known as multisystem inflammatory syndrome in children (MIS-C), characterized by persistent fever and inflammation of several organs, such as the heart and intestines, as well as the lungs to a lesser extent.
