This article explores illustrated children’s books that were published in Soviet Russia during the first five-year plan (1928–1932). Targeting mostly preschool and elementary school children, these books are creatively illustrated, offering their readers highly detailed accounts of economic and political development in the country. Soviet pedagogues perceived this literature as a tool for training “literate spectators,” able to discern social and political importance of images. The article follows this idea, using the books for tracing visual regimes that represented class and ethnicity in the 1920s–1930s. Picture books for children successfully reflected the dual nature of socialist transformations in the USSR, where building new sites of industrial production were closely linked with the building of new nations. Very early on, this literature also documented the bifurcation of this dual process. The detailed portrayal of ethnic distinctions was paralleled by the visual disappearance of the working class, producing a stream of illustrations in which technology and ethnic groups emerged as self-sufficient visual fields, ostensibly disconnected from class, labor, and history.

Post-exposural eye movements were studied in 32 adults and 24 7-yr.-old children. Stimuli were binary figures exposed tachistoscopically in both visual fields simultaneously. The data showed significant correlations between direction of eye movement and locus of recognition for both children and adults. No significant differences were found in frequencies of eye movements of children and adults. The data are interpreted in terms of the facilitative effects of post-exposural eye movements upon perception for both groups.

A metallic nano-trench is a unique optical structure capable of ultrasensitive detection of molecules, active modulation as well as potential electrochemical applications. Recently, wet-etching the dielectrics of metal–insulator–metal structures has emerged as a reliable method of creating optically active metallic nano-trenches with a gap width of 10 nm or less, opening a new venue for studying the dynamics of nanoconfined molecules. Yet, the high surface tension of water in the process of drying leaves the nano-trenches vulnerable to collapsing, limiting the achievable width to no less than 5 nm. In this work, we overcome the technical limit and realize metallic nano-trenches with widths as small as 1.5 nm. The critical point drying technique significantly alleviates the stress applied to the gap in the drying process, keeping the ultra-narrow gap from collapsing. Terahertz spectroscopy of the trenches clearly reveals the signature of successful wet etching of the dielectrics without apparent damage to the gap. We expect that our work will enable various optical and electrochemical studies at a few-molecules-thick level.
