X-ray photoelectron spectra have been used for characterizing changes in the chemical state and composition of the clean surface of single K2CrO4 (potassium chromate) and K2Cr2O7 (potassium dichromate) crystals with Cr(VI) due to air exposure and argon ion bombardment. Their clean surface was prepa...

WINNING OSCAR…From 1893 to 1943Oscar Tschirkywas the Waldorf-Astoria’s public face and a gracious host who made both the great and the not-so-great feel welcome. At left, in 1923; at right, Tschirky samples the first shipment of beer to arrive at the Waldorf-Astoria when the brew beca...
The heat wave of 1934 spread misery from the Midwest to the East Coast. The temperature in New York City hit 101 degrees F (38.3 C) on June 29, and July recorded at least ten days of temps in the mid- to upper 90s. It must have been miserable in the days before air-conditioning,...
Panichi:I don’t believe much has changed in terms of how a bank handles an underperforming borrower. Historically, it’s always been a function of an institution’s aggregated portfolio composition and assessment of the level of existing and potential stress in the book. What has changed is ...
For conductivity measurements, NC films were spin-coated from a solution of NCs in hexane at 2500 rpm onto clean glass substrates with interdigitated source and drain electrodes (30 nm thick Au) spaced 50 mm apart. They were immersed in either 1,2-ethanedithiol solution in acetonitrile (,1%...

During the roughly thirteen years of Prohibition, many Americans had forgotten how to mix a decent cocktail; the concoctions they devised during those dry years were often created to mask the taste of bootleg liquor—sales of Coca-Cola steadily increased throughout the 1920s in part because it...
Subsequently, no large nanoparticles were observed in the high-resolution TEM image of N-G-Ca (Fig. 5g). X-ray photoelectron spectroscopy (XPS) was adopted to unveil the chemical composition and structure of each element in the samples. For N-G-Ca sample, XPS survey spectrum firstly ...
