Nevertheless, although UV radiation has been demonized, less is known about the consequences of sun exposure while using sunscreen, which can lead to high visible light exposure. UV and visible light play key roles in vitamin D synthesis, reduction of blood pressure, among other beneficial effects. In this review, we aim to provide a comprehensive view of the wide range of responses of the human skin to sunlight by revisiting data on the beneficial and harmful effects of UV and visible light. We start by exploring the interaction of photons in the skin at several levels including physical (depth of photon penetration), chemical (light absorption and subsequent photochemical events), and biological (how cells and tissues respond). Skin responses to sun exposure can only be comprehensively understood through a consideration of the light-absorbing molecules present in the skin, especially the light-sensing proteins called opsins. Indeed, many of the cellular responses to sun exposure are modulated by opsins, which act as the “eyes of the skin”.</div>","PeriodicalId":376,"journal":{"name":"Journal of Photochemistry and Photobiology C: Photochemistry Reviews","volume":"47 ","pages":"Article 100403"},"PeriodicalIF":13.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jphotochemrev.2021.100403","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2606851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although N2 constitutes 78.09 % of the earth's atmosphere, however, its conversion to ammonia is strenuous because of its non-polar and triple bond character. To address the burgeoning demand, ammonia is typically synthesized via the conventional energy and capital intensive Haber-Bosch technique utilizing natural gas and releasing tons of (CO2) to the environment. On this basis, cost-effective photon-driven dinitrogen reduction reaction (NRR) is aroused thriving attention as a sustainable and eco-friendly process for ammonia production under ambient conditions. Yet, the photocatalytic ammonia production is not up to the mark for industrial application due to low conversion rate, less catalytic selectivity, ambiguous mechanism, and limited faradic or solar-to-chemical efficiency. Further, the NRR activity of a catalyst essentially depends upon its electronic and surface texture; hence the fabrication of advanced materials is of paramount interest to enhance the performance. The present review covers the underlying mechanism of N2 photoreduction, prevailing theories, different catalytic engineering techniques, various detection methods, and critical challenges encountered in the theme of photofixation of dinitrogen to ammonia. Additionally, the overarching goal of this review is to bestow an outline of recent research articles in earmarking high-caliber photocatalytic systems and hence planting a strong foundation to ensure the succeeding improvement in this promising and hastily stretching field of dinitrogen photofixation research.</div>","PeriodicalId":376,"journal":{"name":"Journal of Photochemistry and Photobiology C: Photochemistry Reviews","volume":"47 ","pages":"Article 100402"},"PeriodicalIF":13.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jphotochemrev.2021.100402","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2802547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many progressive studies have been conducted to expand the family of light-conversion phosphors and exploit their application in sensitized solar cells, bringing emerging opportunities to develop commercial sensitized solar cells. In this review, we survey the development of light-conversion phosphors in sensitized solar cells. First, the application and conversion mechanism of light-conversion phosphors, including up-conversion phosphors, down-conversion phosphors, up/down conversion phosphors, and long-lasting phosphors, are summarized in detail.

HOFs are assembled from organic building blocks through H-bonding interactions. The resultant framework can be further reinforced via weak connections such as π-π, van der Waals, and/or C-H-π interactions. The highly flexible and reversible HOF structures are exceptionally suitable for the realization of smart HOF materials. To this end, it is crucial to unravel and control the photobehavior of these compounds at intimate levels by the use of advanced laser-based spectroscopy and microscopy techniques. The use of light to study the photophysical processes of HOF-based systems will help to trigger further research to expand their applicability in the related fields. This Review surveys the past-10-years contributions on the spectroscopy and photoinduced fast/ultrafast dynamics of HOFs, the interactions between their building units, the effect of light on their photostability, and most important photonic applications. The aim of this work is to give a rich up-to-date summary of photochemistry and related applications of HOFs and their composites. The reviewed HOFs have been divided into different families based on the nature of the linker, with the purpose of offering to the reader a concise understanding of the related photoinduced processes within each family. The relevant applications of HOFs are also briefly summarized to validate their potential use in modern science and technology.</div>","PeriodicalId":376,"journal":{"name":"Journal of Photochemistry and Photobiology C: Photochemistry Reviews","volume":"47 ","pages":"Article 100418"},"PeriodicalIF":13.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.jphotochemrev.2021.100418","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2606852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Well into the 21 st century, scientists have not agreed on the mechanism of action, primary site, and roles of excess energy absorbed by photosynthetic pigments. It is recognized that Photosystem II is the most fragile component during photoinhibition and that excess excitation absorbed by the photosynthetic pigments has a strong impact on it. Consensus is yet to come on terminology, guidelines to study photoinhibition, or boundaries of what can be considered photodamage. Some of these controversies are the result of how we understand the phenomenon of photoinhibition, as this is what determines a given experimental design. Thus, how we understand photodamage depends on the philosophical approach of each group. While some efforts have been made in the parametrization of Photosystem II photoinhibition, an updated review about the concepts of photoinhibition of Photosystem II and how to study it is still pending.

Recently, a growing number of researches focusing on photocatalytic methane conversion under mild conditions have attracted much attention, demonstrating that photocatalytic non-oxidative coupling of methane (PNOCM) is a prospective and green method for methane conversion under mild conditions. Herein, we provide a review of the recent advance, remaining challenges, and prospects in PNOCM.
