In 1972, a brief article titled “Khandud, Village de la Vallée du Wakhan” appeared in Afghanistan 25. The subsequent decades of conflict precluded any follow-up research in Wakhan. The current article, based on field work from 2004 to 2016, examines the present condition of the sites described in 1972, offers a revised analysis of their significance, and introduces newly discovered rock art that connects Wakhan with the Saka culture of Central Asia and illustrates indigenous traditions of the Pamir-Hindukush ethnolinguistic region.

Lost Time

In this paper, I will reflect on my personal memories of Ludovic Mann, friend and mentor to my late father George Applebey, whose archaeological career is also a focus of the paper. They both worked together on Mann's most famous excavations at Knappers Farm, and the nearby painting of the Cochno Stone rock-art panel. However, these are only two examples of their long-term collaboration and friendship, and this paper will explore the broader context within which they worked. This will include consideration of other collaborators, such as J Harrison Maxwell, part of the ‘Ludovic Group’ in the first half of the twentieth century. The important role that all three men played in the development of Scottish archaeology is noted. The paper concludes with developments following Mann's death in 1955 including George Applebey's emergence as a noted amateur archaeologist in his own right, and the fate of the Mann and Applebey collections.

Deep blue organic-emitting fluorophores are crucial for application in white lighting and full color flat-panel displays but emitters with high color quality and efficiency are rare. Herein, novel deep blue AIE luminogens (AIEgens) with various donor units and an acceptor of cyano substituted tetraphenylbenzene (TPB) cores were developed and used to fabricate non-doped deep blue and hybrid white organic light-emitting diodes (OLEDs). Benefiting from its high emission efficiency and high proportion of horizontally oriented dipoles in the film state, the non-doped deep blue device based on CN-TPB-TPA realized a maximum external quantum efficiency 7.27%, with a low efficiency roll-off and CIE coordinates of (0.15, 0.08). Moreover, efficient two-color hybrid warm white OLEDs (CIE<sub>x,y</sub> = 0.43, 0.45) were achieved using CN-TPB-TPA as the blue-emitting layer and phosphor doped host, which realized maximum current, power, external quantum efficiencies 58.0 cd A<sup>-1</sup>, 60.7 lm W<sup>-1</sup> and 19.1%, respectively. This work provides a general strategy to achieve high performance, stable deep blue and hybrid white OLEDs by construction of AIEgens with excellent horizontal orientation
