We are pleased to announce the launch of Photochemistry and Spectroscopy , a new peer-reviewed international journal dedicated to publishing high-quality, cutting-edge research in all areas of photochemistry and spectroscopy. With a strong commitment to scientific excellence and innovation, the journal provides a vibrant platform for the dissemination of original research, critical reviews, and insightful perspectives spanning both fundamental and applied aspects of these dynamic and interdisciplinary fields. We now invite submissions for the inaugural issue of the journal, which will be dedicated to the theme: Photochemistry and Spectroscopy . This first issue aims to bring together outstanding contributions that reflect the breadth and depth of current research in these areas, including but not limited to: molecular photophysics, ultrafast spectroscopy, photoinduced processes, advanced spectroscopic techniques, light–matter interactions, and the design and characterization of photoactive materials and systems. We welcome contributions from researchers across academia, industry, and research institutions, and particularly encourage the submission of works that explore emerging concepts, interdisciplinary approaches, or novel methodologies. The peer-review process will be rigorous, fair, and constructive, ensuring the highest standards of scientific integrity and quality. Accepted papers will be published online immediately upon acceptance and will be part of the official inaugural issue, scheduled for December 2025 . Join us in shaping the scientific impact and visibility of Photochemistry and Spectroscopy from its very first issue. Submission is now open via the journal’s online portal. We look forward to receiving your contribution.

The water treatment sector generates vast amounts of experimental and operational data, yet these datasets remain critically underutilised in advancing intelligent modelling approaches. Such data-driven methodologies are pivotal for enabling predictive analytics, process optimisation, and autonomous control systems in water/wastewater management. We are committed to addressing persistent challenges in developing AI-enhanced computational models that bridge data science with environmental engineering applications. Submissions must not overlap with works that have been published or that are simultaneously being considered for publication elsewhere. Topics of interest include, but are not limited to, the following: Intelligent model methods for water and wastewater treatment process Intelligent model methods for sludge treatment process Intelligent model methods for environmental materials design and optimisation Intelligent model methods for environmental chemistry Keywords : Machine learning; Data-driven model; Environmental engineering; Predictive process control; Smart material optimisation; Resource recovery Instructions for Authors Editor-in-Chief : Prof. Bing-Jie Ni Please contact the editorial office at iwt @sciltp.com if you have any questions.
