The characteristics of colour TV system made on the basis of microscope MBI-15 with the use of imported details are presented. The system can be used for clinico-anatomical conferences, scientific lectures, in teaching, and allows to avoid laborious preparing of colour slides. The design made it possible to keep information (images) in form of figures (for example, by means of a personal computer) and video-cassettes. This may be used in computer morphometry and quantitative analysis in histochemistry.

Vision science imposes rigorous requirements for the design and execution of psychophysical studies and experiments. These requirements ensure precise control over variables, accurate measurement of perceptual responses, and reproducibility of results, which are essential for investigating visual perception and its underlying mechanisms. Because different experiments have different requirements, not all aspects of a display system are critical for a given setting.

Historically, films and television centered men, but there has recently been a shift toward focusing on women and people of color (and women of color) in leading roles. Films and shows like Black Panther, Barbie, and Ashoka reflect this trend, offering more complex stories and diverse representation. Despite progress, stereotypical gender roles persist in many portrayals, but contemporary films and television shows increasingly challenge these norms.

Optimizing the three-primary-color perovskite quantum dots (TPC PQDs) is crucial for achieving ultra-wide color gamut displays. Although encapsulation is an effective strategy to improve the stability and optical performance of the TPC PQDs, the chemicals or environment employed in the coating procedure may attack the CsPbX PQDs and generate defects, damage, and ligand loss. Herein, a mild, facile and universal hexamethylcyclotrisiloxane (D3) in situ ring opening polymerization strategy is successfully developed for efficiently synthesizing high-brightness and extremely stable TPC CsPbX@PDMS (X = Cl, Br, I) nanospheres, with particularly friendlyness for fragile red and blue.

Colloidal quantum dots (QDs) have illuminated computer monitors and television screens due to their fascinating color-tunable properties depending on the size. Here, the electroluminescence (EL) wavelength of perovskite LEDs was tuned via the atomic layer number (ALN) of nanoplates (NPs) instead of the "size" in conventional QDs. We demonstrated efficient LEDs with controllably tailored emission from = 3, 4, 5, and ≥7 ALN perovskite NPs with specific and discrete major peaks at 607, 638, 669, and 728 nanometers.

Academic interest in scientists who regularly appear in the media dates back to Rae Goodell's seminal book "The visible scientists", in which she lists distinct characteristics of visible scientists, including being controversial, articulate, colorful, and reputable as a scientist. Visible scientists thus share relevant media-related characteristics that stand out in their portrayal as a group and are reminiscent of other celebrities' characteristics. However, questions arise: what is special about the celebrity being a scientist? How many and what types of scientists fall into this category? What are the peers' and the public's expectations towards the social role of the visible scientist? To date, work on visible scientists has focused on theorizing them in the context of the relationship between science and its publics and empirical studies have mainly sought to characterize visible scientists and focused on single countries.
