Ultrafast nonequilibrium dynamic process of separate electrons and holes during exciton formation in few-layer tungsten disulfide.

Phys Chem Chem Phys 2021 Mar 23;23(12):7135-7144. Epub 2021 Mar 23.

School of Physics and Optoelectronic Engineering, Guangdong University of Technology, Guangzhou 510006, Guangdong, China.

Femtosecond transient absorption spectroscopy has been employed to unravel separate initial nonequilibrium dynamic processes of photo-injected electrons and holes during the formation process of the lowest excitons at the K-valley in few-layer tungsten disulfide. Charge carrier thermalization and cooling, as well as concomitant many-body effects on the exciton resonances, are distinguished. The thermalization of holes is observed to be faster than that of electrons. Read More

Physician Responsiveness to Positive Blood Culture Results at the Minneapolis Veterans Affairs Hospital-Is Anyone Paying Attention?

Fed Pract 2021 Mar;38(3):128-135

is a Medical Student at Case Western Reserve University School of Medicine in Cleveland, Ohio. is a Surgeon and Assistant Service Chief at the Minneapolis Veterans Affairs Health Care System in Minnesota and an Assistant Professor of Surgery at the University of Minnesota.

Background: Patients presenting with suspected infections are typically placed on empiric broad-spectrum antibiotics. With mounting evidence supporting the efficacy of using the narrowest spectrum of antimicrobial therapy to cover the suspected pathogen, current guidelines recommend decreasing the breadth of coverage in response to culture results both in relation to microbe identification and antibiotic sensitivity.

Methods: A retrospective chart review of electronic health records at the Minneapolis Veterans Affairs Medical Center (VAMC) in Minnesota was performed for 208 positive blood cultures with antibiotic spectrum analysis from July 1, 2015 to June 30, 2016. Read More

Cerebral venous sinus thrombosis and thrombocytopenia after COVID-19 vaccination - a report of two UK cases.

Brain Behav Immun 2021 Apr 12. Epub 2021 Apr 12.

Department of Neurology, King's College Hospital NHS Foundation Trust, London, UK. Electronic address:

Recent reports have highlighted rare, and sometimes fatal, cases of cerebral venous sinus thrombosis (CVST) and thrombocytopenia following the Vaxzevria vaccine. An underlying immunological mechanism similar to that of spontaneous heparin-induced thrombocytopenia (HIT) is suspected, with the identification of antibodies to platelet factor-4 (PF4), but without previous heparin exposure. This unusual mechanism has significant implications for the management approach used, which differs from usual treatment of CVST. Read More

Oxidative Addition of Aryl and Alkyl Halides to a Reduced Iron Pincer Complex.

J Am Chem Soc 2021 Apr 8;143(15):5928-5936. Epub 2021 Apr 8.

Department of Chemistry, Princeton University, Princeton, New Jersey 08544, United States.

The two-electron oxidative addition of aryl and alkyl halides to a reduced iron dinitrogen complex with a strong-field tridentate pincer ligand has been demonstrated. Addition of iodobenzene or bromobenzene to (3,5-MeCNC)Fe(N) (3,5-MeCNC = 2,6-(2,4,6-Me-CH-imidazol-2-ylidene)-3,5-Me-pyridine) resulted in rapid oxidative addition and formation of the diamagnetic, octahedral Fe(II) products (3,5-MeCNC)Fe(Ph)(N)(X), where X = I or Br. Competition experiments established the relative rate of oxidative addition of aryl halides as I > Br > Cl. Read More
