Background: Lighting is an important component of consistent, high-quality dermatologic photography. There are different types of lighting solutions available.
Objective: To evaluate currently available lighting equipment and methods suitable for procedural dermatology.
Materials And Methods: Overhead lighting, built-in camera flashes, external flash units, studio strobes, and light-emitting diode (LED) light panels were evaluated with regard to their utility for dermatologic surgeons. A set of ideal lighting characteristics was used to examine the capabilities and limitations of each type of lighting solution. Recommendations regarding lighting solutions and optimal usage configurations were made in terms of the context of the clinical environment and the purpose of the image.
Results: Overhead lighting may be a convenient option for general documentation. An on-camera lighting solution using a built-in camera flash or a camera-mounted external flash unit provides portability and consistent lighting with minimal training. An off-camera lighting solution with studio strobes, external flash units, or LED light panels provides versatility and even lighting with minimal shadows and glare.
Conclusion: The selection of an optimal lighting solution is contingent on practical considerations and the purpose of the image.

Electronic devices cover a large subset of daily life gadgets which use power to run, hence increasing the load of the energy needs and indirectly impacting greenhouse gas emissions. Smart electrochromic windows provide a solution to this through remarkable energy saving by adjusting optical behavior depending on the environmental conditions. Since the electrochromic windows also need power to run, a self-powered electrochromic panel will be a better solution.

This study presents the synthesis and characterization of CsNaBiCl nanocrystals (NCs) doped with varying concentrations of In to improve their luminescent properties. Utilizing a colloidal solution method, we systematically varied the In concentration to identify the optimal alloying level for enhancing the photoluminescence (PL) properties of the CsNaBiCl NCs. Structural analysis confirmed that the In-alloyed NCs maintained high crystallinity and a uniform cubic shape.

ConspectusLight-driven polymerizations and their application in 3D printing have revolutionized manufacturing across diverse sectors, from healthcare to fine arts. Despite the popularized notion that with 3D printing "imagination is the only limit", we and others in the scientific community have identified fundamental hurdles that restrict our capabilities in this space. Herein, we describe the group's efforts in developing photochemical systems that respond to nontraditional colors of light to elicit the rapid, spatiotemporally controlled formation of plastics.

Anthocyanins (ANCs) are water-soluble pigments with antioxidant properties, offering potential as alternatives to synthetic food colorants. However, their stability is compromised by factors such as pH, temperature, and light exposure. Previous research demonstrated improved pH stability in black grape ANCs through cobalt ion (Co) complexation.
