We have investigated the adsorption of perylene-3,4,9,10-tetracarboxylic acid dianhydride (PTCDA) on the clean and on the oxygen pre-covered Cu(100) surface [referred to as (√2 × 2√2)R45° - 2O/Cu(100)] by scanning tunneling microscopy (STM) and low energy electron diffraction (LEED). Our results confirm the (4√2 × 5√2)R45° superstructure of PTCDA/Cu(100) reported by A. Schmidt et al. [J. Phys. ...

3.1 CHAPTER SUMMARY The solid state structure-property behavior was investigated of a series of poly(ether-blockamide) PEBAX thermoplastic elastomers based on nylon 12 and polytetramethylene oxide with varying hard segment content. Particular emphasis was placed on better defining the morphological features of this series of commercially available materials. Compression molded and solution cast...

The paper analyzes of the state PR and propaganda work Russian side during first stage (February — May 2022) special military operation (SNO) in Ukraine. In particular, author emphasizes undoubted combat successes troops (“basis”). Nevertheless, he considers that terms superstructure, political leadership is underperforming, conceding to both Western Ukrainian opponents. specific concerns are a...

The LEED pattern of clean (101) surfaces of Au show a characteristic (1 X 2) superstructure. The diffuseness of reflections in the reciprocal [OlO] direction is caused by onedimensional disorder of chains, strictly ordered into spatial [lo]] direction. There is a transition from this disordered superstructure to the normal (1 X 1) structure at 420 r 15°C. The angular profiles of the (04) and (0...
