Raman scattering spectroscopy of liquid nitrogen molecules: An advanced undergraduate physics laboratory experiment

We describe a straightforward and highly visual experiment designed to demonstrate Raman scattering spectroscopy by measuring the vibrational energy spacing of nitrogen molecules in the liquid phase. Interpretation of the spectrum teaches the principles of elastic and inelastic light scattering and the intrinsic properties of molecules. The use of a pulsed Nd:YAG laser with high peak power lead...

Advanced photoelectric effect experiment beamline at Elettra: A surface science laboratory coupled with Synchrotron Radiation.

We report the main characteristics of the advanced photoelectric effect experiments beamline, operational at Elettra storage ring, featuring a fully independent double branch scheme obtained by the use of chicane undulators and able to keep polarization control in both linear and circular mode. The paper describes the novel technical solutions adopted, namely, (a) the design of a quasiperiodic ...

Preventive Maintenance of Advanced Manufacturing Systems: A Laboratory Experiment and Its Implications for the Human-Centered Approach

Due to rising demands for flexibility of the manufacturing process, there is a strong need to reorganize the task spectrum of the shop-floor staff by integrating, e.g., preventive maintenance functions. In this human-centered approach the shop-floor staff requires support in performing these additional functions. Here, based on an empirical investigation of the knowledge requirements in prevent...

Audit of Advanced Laboratory Investigations.

BACKGROUND Advanced laboratory investigations at reference laboratories play a key role in the diagnosis of the disease, but misuse of this precious and expensive tool may misguide the physician in patient management. This study was carried out as an audit of investigations performed at a reference laboratory, in order to assess their cost effectiveness, to identify various errors, the degree o...
