However, the peak broadening that naturally appears in experimental infrared spectra due to physical effects and instrumental limitations is usually not part of the quantum mechanical modeling method. Here, a new user-friendly application, CaRIn (Catalysis Research with Infrared Spectroscopy), within the CaRMeN platform is proposed, in which the peak width can be approximated by means of Gaussian functions. The peak broadening can be adjusted in real time and compared to both experimental and other simulated spectra. The application integrates functionality for better visual comparability of different spectra and a database of spectra to enhance workflow efficiency.</p>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"97 5","pages":"463-471"},"PeriodicalIF":1.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cite.202400150","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After an electrolyte screening, four electrolytes were chosen for an in-depth analysis of the supporting electrolyte's ion influence.

Die vielen Systeme, auch innerhalb einer Verlagsgruppe, und unterschiedliche Konten oder Anmeldedaten für die verschiedenen Zeitschriften zählen zu den häufigsten negativen Rückmeldungen, die uns in den Redaktionen erreichen. Hinzu kommen zuweilen lange Uploadzeiten oder unverständliche Anweisungen. Um hier Abhilfe zu schaffen, hat Wiley mit Research Exchange ein modernes Manuskriptsystem entwickelt und dieses in den letzten Jahren bereits für viele Zeitschriften eingeführt. Mittlerweile wurden über 1200 Wiley-Zeitschriften auf die neue Plattform umgestellt und weitere werden im Laufe des Jahres folgen.</p><p>Wiley hat sich mit Research Exchange zum Ziel gesetzt, den wissenschaftlichen Einreichungsprozess zu vereinfachen und zu beschleunigen. Dies gelingt durch die Automatisierung verschiedener Prozessschritte, die Integration von künstlicher Intelligenz und eine intuitive Benutzeroberfläche. Einer der Vorteile für Sie als Autoren und Gutachter ist, dass nur noch ein Account für alle Wiley-Zeitschriften auf Research Exchange benötigt wird. Sie können dieselben Login-Daten verwenden, mit denen Sie sich auch zum Beispiel bei Wiley Online Library oder anderen Wiley-Plattformen anmelden, oder bereits bestehende Konten bei Google, ORCID, Microsoft oder Apple nutzen. Seit Mitte November setzt nun auch die <i>Chemie Ingenieur Technik</i> das Einreichungsportal von Research Exchange ein. Erreichen können Sie es über https://wiley.atyponrex.com/journal/CITE. Sie finden dort weiterhin die bewährten Artikeltypen Forschungsarbeit und Kurzmitteilung sowie Übersichtsbeitrag und Essay zur Auswahl. Sollte einmal ein Corrigendum oder Erratum nötig sein, kann dieses auch bequem über das Portal übermittelt werden. Während in Forschungsarbeiten und Kurzmitteilungen neue, bisher unveröffentlichte wissenschaftliche Erkenntnisse in unterschiedlichem Detailgrad präsentiert werden, geben Übersichtsbeiträge eine Zusammenfassung und Analyse über den aktuellen Stand eines Forschungsthemas und identifizieren bestehende Wissenslücken. Der Essay hingegen ist kein streng wissenschaftlicher Beitrag und von der Struktur her flexibler. Es geht häufig um eine persönliche, kritische Auseinandersetzung mit einem bestimmten Thema, die auch von einer subjektiven Note der Autoren geprägt sein kann. Essays können Konzeptpapiere sein, Denkanstöße geben, zur Diskussion anregen oder auch aktuelle Entwicklungen in der Community beschreiben.</p><p>Wenn Sie sich jetzt selbst ein Bild von Research Exchange machen möchten, überzeugen Sie sich gerne von unserer neuen Einreichungsseite. Neben Beiträgen zu den aktuell offenen Themenheften, wie Elektrifizierung chemischer Prozesse oder Process Engineering, freuen wir uns auch immer über alle anderen Einreichungen aus der ganzen Bandbreite der technischen Chemie und Biotechnologie.</p>","PeriodicalId":9912,"journal":{"name":"Chemie Ingenieur Technik","volume":"97 3","pages":"135"},"PeriodicalIF":1.5,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cite.202500025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
