How to increase the brightness of fluorescent proteins?4 answersOne approach to increasing the brightness of fluorescent proteins is through the design of mutants with increased photostability. For example, the EGFP-Y145L mutant has shown reduced photooxidation and photobleaching. Another strategy is the de novo computational design of proteins with predefined three-dimensional structures. Mini Fluorescence Activating Proteins (mFAPs) have been designed to activate the fluorescence of an exogenous chromophore, resulting in increased brightness. Quantum mechanics and molecular dynamics simulations have been used to investigate how molecular flexibility influences brightness, showing that resistance to dihedral angle rotation of the chromophore is critical. Additionally, a theory has been proposed connecting the amino acid sequence of a light-absorbing protein with its fluorescence brightness, suggesting that electrostatic changes can make light emission brighter. Finally, tuning the local electric field inside the protein through mutations can increase the peak 2-photon absorption cross section.
How to make illumination better?5 answersTo improve illumination, various methods and devices have been developed. One approach is to use an image processing method that enhances the visibility of low illumination images by using window selection and stretching techniques. Another method involves the use of a nonimaging light guide that collimates and diffuses light emitted by a light source, providing improved light output without the need for complicated optical arrangements. Additionally, a mirror matrix assembly can be used to reflect light from one or more light sources and illuminate objects or surfaces, making it suitable for various applications such as sports fields and road tunnels. Another approach is to design an illuminating device with a heat radiation cover and module, which effectively dissipates heat and improves the concentration of light. Furthermore, winding a Cold Cathode Fluorescent Lamp into a spiral can substantially increase the light flux available, providing illumination equivalent to incandescent lamps.
What is the standard light intensity when working?5 answersThe standard light intensity when working varies depending on the specific task and environment. In UK offices, the commonly targeted illuminance is 500 lux on the working plane, but there is evidence suggesting that a reduced illuminance would not significantly affect visual performance. However, it is important to consider expectations and the perceived brightness of the space, as a reduced illuminance may lead to a sense of gloom and potentially affect motivation. Different types of activities may require different levels of illumination, and for exacting visual tasks, 20 to 25 foot-candles (approximately 215 to 269 lux) are recommended. It is also suggested that varying light levels throughout the day can promote healthier individuals and contribute to better results for companies.

Why has a quantum dot solar cell not a very high efficiency?
5 answers
Quantum dot solar cells face efficiency challenges due to various factors. Colloidal quantum dots (CQDs) suffer from carrier recombination issues within the material, impacting performance.

In trait theory Is behavior free or conditioned?
5 answers
Behavior in trait theory is considered to be a combination of both free and conditioned elements. Trait theory defines personality traits as habitual patterns of behavior that exhibit relative stability over time and influence behavior. Conditioning, including operant and classical types, plays a crucial role in shaping behavior and cognition, breaking informational bottlenecks and accounting for cognition. In experimental settings, responses were automatically recorded and reinforced, showing how conditioning influences behavior. Moreover, social environments can impact the acquisition of avoidance responses, indicating the role of conditioning in behavior modification. Therefore, behavior in trait theory is a blend of inherent traits (free) and learned responses (conditioned), with conditioning playing a significant role in shaping behavior.
