While other halides of CsSnX3 (e.g. X=Cl, I) are extremely air sensitive and change color within seconds, illumination tests performed on unencapsulated CsSnBr3 devices in ambient air show no change over the span of hours.
The purpose of this study is to investigate whether cyanobacteria possess light-dependent electrogenic activity (i.e. are capable of depositing electrons to the extracellular environment in response to illumination), to test whether the electrogenic activity is generic and to probe the mechanism of the electrogenic response.
Similarly, a more negative judgement of ambiguous spatial stimuli has been reported in response to acute induction of a negative state through illumination of test apparatus with bright light, although this occurred only in rats that had been trained in low lighting levels then tested in bright light (Burman et al., 2009).

Using face images that were captured under controlled and uncontrolled illumination, the tests were conducted in three different cases, namely controlled-controlled (C-C), controlled-uncontrolled (C-U), and uncontrolled-uncontrolled (U-U) as training-test combinations.
The light source was the best amongst the illumination methods tested.
Shapes that had been assigned to a given level of room illumination were tested as a block, i.e., each was display successively with illumination being the same.
The visual acuity depends strongly on the illumination of the test target, and this is true of both daylight (photopic) and night (scotopic) vision; thus, with a brightly illuminated target, with the surroundings equally brightly illuminated (the ideal condition), the visual acuity may be as high as two.
The shift to 30°C was completed within 2 3 minutes from the start of additional illumination, and the test was conducted after another 2 minutes.
There was no illumination of the test chambers during experimental sessions.
