[FeFe]-Hydrogenase with Chalcogenide Substitutions at the H-Cluster Maintains Full H2 Evolution Activity.

Angewandte Chemie (International ed. in English)

Noth J, Esselborn J, Güldenhaupt J, Brünje A, Sawyer A, Apfel UP, Gerwert K, Hofmann E, Winkler M, Happe T.
PMID: 27214763
Angew Chem Int Ed Engl. 2016 Jul 11;55(29):8396-400. doi: 10.1002/anie.201511896. Epub 2016 May 23.

The [FeFe]-hydrogenase HYDA1 from Chlamydomonas reinhardtii is particularly amenable to biochemical and biophysical characterization because the H-cluster in the active site is the only inorganic cofactor present. Herein, we present the complete chemical incorporation of the H-cluster into the...

PMID: 18284969
IEEE Trans Ultrason Ferroelectr Freq Control. 1989;36(2):204-8. doi: 10.1109/58.19152.

An approximate analytical formulation is presented that allows for the calculation of acoustic pressure thresholds for transient cavitation over a variety of frequencies and host fluid parameters. Specifically, R.E. Apfel's (1986) theory is extended to include an estimate of...

Rev Sci Instrum. 1978 Feb;49(2):224. doi: 10.1063/1.1135371.

Objects can be levitated by radiation pressure forces in an acoustic standing wave. In many circumstances it is important that the standing wave frequency remain locked on an acoustic resonance despite small changes in the resonance frequency. A self-locking...

Intracranial epidermoid cysts are benign lesions that typically remain asymptomatic; however, although histopathologically benign, these cysts can rarely undergo malignant transformation into squamous cell carcinoma. Primary intracranial squamous cell carcinoma carries a poor prognosis as optimal treatment modalities remain...
