As a non-noble metal, copper oxidizes more easily to positive valence (Cu+ or Cu2+) than same-family elements Au or Ag. In general, this chemical property is mainly determined by electron structure. Can we change the chemical properties of an element by regulating its electron structure? Can Cu act as a noble metal in catalytic reactions?
PISCATAWAY, NJ - College students who binge drink are frequently posting on social media while intoxicated and show signs of social media "addiction," according to a new study.
Students later may regret their drinking-related posts and experience other negative consequences from combining social media and alcohol use. The research appears in the latest edition of the Journal of Studies on Alcohol and Drugs.
BOSTON (Dec. 17, 2018)--Over the past two decades, labels such as the U.S. Nutrition Facts Panel on packaged foods, calorie counts on national restaurant menus, front-of-pack labels encouraging healthier eating, and "low-sodium" or "fat-free" identifiers have been developed in order to promote healthier choices. But do they work?
More than one in eight U.S. adults (12.6 percent) used benzodiazepines in the past year, up from previous reports. Misuse of the prescription drugs accounted for more than 17 percent of overall use, according to a study published online today in Psychiatric Services in Advance. The researchers defined misuse as any way a doctor did not direct, including using the drug without a prescription or more often or longer than prescribed. Misuse was highest among young adults 18 to 25 (5.6 percent) and was as common as prescribed use.
Hope has emerged for patients with a serious type of bone marrow cancer as new research into a therapeutic drug has revealed improved outcomes and survival rates.
In the largest study of its kind, researchers at Newcastle University, UK, have led national research into the treatment of patients with newly diagnosed myeloma.
The results, published online today by The Lancet Oncology, show an improvement for those who received ongoing therapy with a drug called lenalidomide, compared to those not receiving it.
Rudeness. Sarcastic comments. Demeaning language. Interrupting or talking over someone in a meeting. Workplace incivilities such as these are becoming increasingly common, and a new study from Portland State University and University of Illinois researchers found this behavior has the potential to not only negatively affect an employee's sleep but their partner's as well.
When young children experience violence or poverty, the effect can last well into adulthood. But new research from the Emory School of Medicine suggests that a strong parental relationship could override some of these effects, by changing how children perceive the environmental cues that help them distinguish between what's safe or dangerous.
ORLANDO, Fla. (December 11, 2018) - An innovative care model developed by Nemours Children's Hospital for children with autism spectrum disorders (ASD) in the emergency department (ED) reduces the use of medication administered to kids who are prone to stress and sensory overload in this care setting. Information about this care model was presented today at the Institute for Healthcare Improvement's National Forum.
Researchers predict that death rates from cancer will fall in 2018 in Australasian countries and in Russia. However, a greater proportion of the population will die in Russia from the disease than in any of the other countries, mainly because of the large numbers of men who still smoke.
CHAMPAIGN, Ill. -- In the state of Baden-Wurttemberg, Germany, 16-year-old students in middle-track schools decide whether to stay in school to pursue an academic career or enroll in a vocational training program. A new study offers evidence that the path they choose influences their personality years later.
The research is reported in the journal Psychological Science.
