This issue of the IBM journal describes recent advances in the field of nanoscience, with an emphasis on cathode lens-based microscopy methods, including LEEM (low-energy electron microscopy), PEEM (photoemission electron microscopy), and other related analytical approaches. Papers highlight scientific advances and instrumental developments on topics that include thin films, organic films, surf...

We discuss the application of photoelectron angular distributions as a probe of time-evolving rovibrational wavepackets. A physical picture is drawn of the mechanism through which rotation–vibration coupling mechanisms are reflected in the time-dependent photoionisation asymmetry parameters. The effects of complicating features that may obscure the interpretation of time-resolved photoelectron ...

To establish whether the compromised need/the label effect is a frequently occurring phenomenon or not, available studies of the phenomenon are examined and claims are comparedwith evidence. Studies that reportedly have verified the phenomenon are shown to suffer from technical problems that put the claim of verification in doubt. Studies that have reported low percentages of questions changing...
