In this regard, structural changes, as well as static structures, have been scrutinized as essential elements in understanding and controlling the function of a protein. In particular, the structural change in the solution phase needs to be elucidated to properly understand protein functions under physiological conditions. Time-resolved x-ray liquidography (TRXL), also known as time-resolved x-ray solution scattering, has attracted attention as a powerful experimental method for studying the structural dynamics of proteins in the solution phase. Initially, TRXL was used to study the structural dynamics of small molecules in the solution phase, and later, its application was extended to probe the structural changes in proteins. Via TRXL, structural changes ranging from large quaternary movements to subtle rearrangements of the tertiary structures have been successfully elucidated. In this review, we introduce various studies using TRXL to investigate the structural dynamics of proteins. These include early TRXL studies on model systems, those on photoreceptor proteins, and recent studies using stimuli beyond the direct photoexcitation of proteins.","PeriodicalId":72559,"journal":{"name":"Chemical physics reviews","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44250086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cuprous oxide photocathode, one of the best-performing oxide photocathodes, possesses a theoretical photocurrent density of up to 14.7 mA cm−2 and a photovoltage as large as 1.6 V, making it possible to convert solar energy into hydrogen energy in a low-cost way. Herein, a comprehensive review of improving the solar water splitting performance of the cuprous oxide photocathode is presented with a focus on the crucial issues of increasing photocurrent density, photovoltage, and durability from the aspects of solving the incompatibility between the electron diffusion length and optical absorption distances, improving interfacial band alignment, revealing the impact of deficiencies, and introducing protective overlayers. We also outline the development of unassisted solar water splitting tandem devices with the cuprous oxide photocathode as a component, emphasizing the critical strategies to enhance the transmittance of the cuprous oxide photocathode, laying a solid foundation to further boost solar to hydrogen conversion efficiency. Finally, a perspective regarding the future directions for further optimizing the solar water splitting performance of the cuprous oxide photocathode and boosting solar to hydrogen conversion efficiency of the unbiased tandem device is also presented.","PeriodicalId":72559,"journal":{"name":"Chemical physics reviews","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46939764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moving forward generally requires the assistance of useful models that are adapted to currently used materials and device architectures. The least understood part of the charge generation is the first step of the exciton dissociation, and new or refined models are being suggested. However, many of today's questions have been asked before, going back almost an entire century. We have gone to the 1930s and attempted to critically review significant contributions on equal footing. We find that Onsager's and Frenkel's models have a similar foundation but were developed to suit very different materials (ions in solutions vs electrons in semiconductors). The contribution by Braun or the Onsager–Braun model can be considered wrong, yet it was instrumental for the field's development. The community practically ignores one of the most promising models (Arkhipov–Baranovskii). Hot exciton dissociation has many faces due to “hot” being a relative term and/or the heat being stored in different ways (electronic, vibronic, etc.). Entropy considerations are instrumental in simplifying the picture, yet they add no physics compared to the full-3D models. We hope that by emphasizing the physical picture of the various models and the underlying assumptions, one could use them as a stepping stone to the next generation models.","PeriodicalId":72559,"journal":{"name":"Chemical physics reviews","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42868777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we highlight some of the recent developments shedding new light on battery materials and electrochemistry via TEM. Studying battery electrode processes depending on the type of electrolytes used and the nature of electrode–electrolyte interfaces established upon battery cycling conditions is key to further adoption of battery technologies. To this end, in situ/ operando TEM methodologies would require accommodating alongside correlation microscopy tools to predict battery interface evolution, reactivity, and stability, for which the use of x-ray computed tomography and image process via machine learning providing complementary information is highlighted. Such combined approaches have potential to translate TEM-based battery results into more direct macroscopic relevance for the optimization of real-world batteries.","PeriodicalId":72559,"journal":{"name":"Chemical physics reviews","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43646382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among numerous techniques for monitoring heterogeneous reactions, dark-field microscopy offers reliable data regardless of specific reaction conditions. In addition, plasmonic nanoprobes provide high sensitivity in a sub-wavelength resolution due to localized surface plasmon resonances susceptible to the dielectric change of objects and surroundings. By clever reaction cell design and data analysis, nanoparticle signals can be parallelly analyzed under variable reaction conditions in a controlled manner. This technique effectively measures the heterogeneity of individual nanoparticles for reaction monitoring. A wide range of chemical and electrochemical reactions have been monitored in situ and in operando at a single-particle level in this way. The advancement of localized surface plasmon scatterometry with simulation techniques approaches sub-particle accuracy in a high temporal resolution up to microseconds. Combining other in situ spectroscopic methods would make dark-field scatterometry a versatile tool for various reaction monitoring and sensing applications.","PeriodicalId":72559,"journal":{"name":"Chemical physics reviews","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47733102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
