Mandibular advancement devices(MADs) are widely used treatments for obstructive sleep apnea. MADs function by advancing the lower jaw to open the upper airway. To increase patient comfort, most patients allow the mouth to be opened. However,not all systems maintain the lower jaw in a forward position during mouth opening, which results in the production of a retrusion that favors the collapse of the upper airway. Furthermore, the kinematic behavior of the mechanism formed by the mandible-device assembly depends on jaw morphology. This means that, during mouth opening, some devices cause lower jaw protrusion in some patients, but cause its retraction in others. In this study, we report the behavior of well-known devices currently on the market. To do so, we developed a kinematic model of the lower jaw device assembly. This model was validated for all devices analyzed using a high-resolution camera system. Our results show that some of the devices analyzed here did not produce the correct behavior during patient mouth opening.

Carbonaceous materials including carbon nanotubes/nanofibers, graphene, graphene oxide, reduced graphene oxide,graphyne, graphdiyne, carbon quantum dots and fullerenes have gained considerable attention in the recent years for their unique properties such as high conductivity, excellent stability and biocompatibility. The integration of these carbonaceous materials into Zscheme and S-scheme heterojunctions has emerged as a transformative strategy to enhance the photocatalytic efficiency for energy conversion applications. This review delves into the fundamental principles of clean energy generation such as photocatalytic H2generation and CO2reduction, elucidating their respective mechanisms and advantages. Furthermore, various types of carbonaceous materials, their synthesis and construction of Z-scheme and S-scheme heterojunctions are discussed emphasizing their role in promoting charge separation, reducing recombination losses and extending the spectral response range. With the focus on solar fuel production,the recent advancements in carbonaceous based Z-scheme and S-scheme heterojunctions are discussed and summarized for photocatalytic H2generation and CO2reduction. Lastly, the current bottlenecks and challenges in the field of carbonaceous based photocatalysts are discussed with the valuable insights for future development in this particular field.

Sustainability is a leading trend in the context of food production. Additionally， consumers increasingly demand safer and less-processed products. Among the different technologies used to maintain the quality and extend the shelf-life of fresh and minimally-processed food， natural antimicrobial agents offer a promising strategy to replace conventional compounds. In this regard， phage lytic proteins or lysins， such as endolysins and virion-associated peptidoglycan hydrolases (VAPGHs)， have been proposed as a viable option for the avoidance and elimination of undesirable bacteria within the food production chain. Even when applied exogenously， these proteins can degrade the bacterial cell wall maintaining their lytic activity. This feature， alongside their modular structure， which can be exploited for bioengineering， provides significant biotechnological potential. However， despite the promising properties of lysins， the main obstacle for their commercialization is the limited legal information regulating their use. This challenge underscores the need to navigate complex regulatory pathways. The primary objective of this review is to address this crucial gap and summarize the many prospective applications of endolysins during the different stages of food production. By doing so， we aim to provide clarity and insight into the regulatory challenges that must be overcome for the successful utilization of lysins.
