The workshop, which took place in a hybrid format, welcomed a total of 127 participants from 38 nations, with 57% attending in person and 43% online (Figure 1). See more details in our photo gallery (https://www.sensor fint.eu/2021/10/05/1st-sensorfint-international-worksh op-porto-photo-gallery/). The event, entitled “Smart Spectral Sensors for Agri-Food Quality and Process Control,” aimed to stimulate the interaction between a range of stakeholders with particular attention paid to highlighting the opportunities for including NIR sensors as a key part of the on-going digital transformation in food industries. In that regard, the event included several showcases from industry both from equipment manufacturers including Perkin Elmer and Bruker, industrial service providers such as AUNIR, and industrial endusers such as Barilla (Figure 2). From the local agrofood industrial ecosystem, and very importantly, the active presence of Portugal Foods, a federation of the majority of food companies in Portugal, deserves to be highlighted. The event counted also with Hamamatsu, EndressþHauser, and Siroco (mechatronics) as sponsors and active participants. The scientific programme included 16 oral and 36 poster presentations, which were articulated around three main topics. The first, “Smart Sensors in AgroFood,” covering the state of the art and the new domains of application, demonstrated the big advances that have been observed with the application of NIRS in the agri-food production process aiming to assure food integrity. The second topic covered the “Current Challenges in Process Control (PAT) for Food Analysis,” with the requirements for accuracy and sensitivity as well as calibration transferability between different devices being popular subjects.

The “Chambersburg Conference” will hold sessions from July 30th and to Aug 5th, 2022. It is an excellent opportunity to meet collaborators and the main contributors in areas such as chemometrics, sampling, hyperspectral imaging, and process analytical technology. Recent advances in instrumentation, analytical tools, and methods to enable fast and robust measurements for environmental, agriculture, chemical, petrochemical, and pharmaceutical applications will be discussed along with current and upcoming trends. As in previous editions, the conference will kick off with short courses in vibrational spectroscopy, chemometrics, and data pretreatments for general and intermediate levels. The morning and evening sessions will be complemented with staple activities such as “Predicting your own time” where the time spent walking or running across a nearby trail based on a previous calibration run will be performed and the “chemometrics shootout” where a challenging data set is provided a few weeks before the conference for participants to use their skills and develop the best models. Finally, the 2020 and 2022 Birth Awards will be presented during the closing ceremony. The conference will be in honor to one of its founders, Karl Norris, and a Memorial Session will be organized by his lifelong friend and colleague Phil Williams.","PeriodicalId":113081,"journal":{"name":"NIR News","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131308077","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}

It involves an “interpretable machine learning” that analyses more than 350 million absorbance spectra, requiring 418 GB of data storage, without the use of black box operations. The 159-channel high-resolution hyperspectral wood “video” in the 500–1005 nm range was reduced to five known and four unknown variation components of physical and chemical nature, each with its spectral, spatial and temporal parameters quantified.

Despite this time being held as a virtual event, it was a highly successful symposium met with high interest from the wide audience – as evidenced by many excellent presentations, around which numerous vivid discussions developed. During the conference, four workshops were offered, focused at discussing few areas essential for NIR spectroscopy and its applications. Excellent workshops were provided by Professors Heinz Siesler, Hui Yan, Dolores Pérez-Marín and Tom Fearn, in which invaluable knowledge was shared with the participants of the conference. Among these renowned experts, I had the honour to offer my contribution with the workshop aimed at the physicochemical foundations of NIR spectroscopy, an area that seldom is exhaustively presented in the textbooks. The workshop aimed at shedding light on the complex world of overtone and combination bands and was met with a considerable interest from the participants. As many questions have been asked both during the dedicated Q&A session, as well as through other channels and private correspondence, I would like to provide a short recapitulation of the workshop in the form of this brief article. Some of the most essential ‘take home messages’, such as the origin of the intensity variation of the overtone bands and the famous ‘selection rule’ of the harmonic oscillator, among others will be briefly outlined here.","PeriodicalId":113081,"journal":{"name":"NIR News","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116949290","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}

Prof. Pozzi owes his training to prof. Roberto Todeschini, head of the Milano Chemometrics and QSAR Research Group, and since then he transmitted his passion for chemometrics to his students and among them to Barbara Giussani, a young student (this was me at that time!) interested in analytical chemistry.

Mirisola, A. D. Zotte","doi":"10.1177/09603360211059287","DOIUrl":"https://doi.org/10.1177/09603360211059287","url":null,"abstract":"Italian researchers involved in near infrared (NIR) spectroscopy present themselves to the international community. Following the example of these colleagues, we introduce the activity of the NIRSXRF-wet chemistry laboratory and the active research groups. The NIRS section of the laboratory was founded in 1994, from the intuition of Igino Andrighetto and Paolo Berzaghi, with the purchase of a NIRSystem 5000 monochromator instrument (FOSS, Hilleroed, DK). The laboratory immediately assumes relevance in applicative research in the agriculture field and attracts the interest of private companies and farmers who start stipulating contracts for analyses, even due to the intuition of calibrating the instrument for the rapid analysis of wet samples, such as fodder, food, rations for cows, etc. Paolo Berzaghi distinguishes himself in the international NIR community due to his close contact with John Shenk. In 1992, Antonella Dalle Zotte also began to approach NIR technology thanks to the collaboration with Giorgio Masoero, one of the Italian pioneers of NIR technology, focusing the first studies on the quality estimation of muscle foods with NIR instruments. Massimo Mirisola and Lorenzo Serva join the laboratory in subsequent years, and new instruments are purchased: a second NIRSystem 5000 (spinning cup module) and a CORONA 45 (CARL ZEISS AG, Jena, DE). In the early 2000s, the field of interest expands to human food quality and authenticity. Between 2004 and 2010, the research group turns its attention to portable instruments, and research is carried out for their application on agricultural machinery, such as combine harvesters, mixer wagons and grape harvesting machines, working in close collaboration with the industry. The new commitments require the hiring of two young graduates, Francesco Benozzo and Jacopo Ferlito. Subsequently, two startups are founded, Grainit Srl (Padova, IT) and ITPhotonics (Fara Vicentino, IT), and some patents are filed on the implementation of NIR instrument or its application on operating machines. In 2011, the research laboratory is included in the Department of Animal Medicine, Production and Health (MAPS) and provides wet chemistry, NIRS and X-Ray Fluorescence (XRF) analyses, also offering a commercial service to interested stakeholders (in particular to agriculture and livestock sectors). The laboratory purchases a Spectrastar 2500 (Unity Scientific, Milford, MA, USA) and a Nicolet Avatar 360 FT-IR (Thermo Fisher Scientific Inc, Waltham, MA, USA), and as such equipped, it also responds to the growing demand for analytical service for products and byproducts destined for biogas production plants. In recent years, following the development of portable instruments, the laboratory provides a calibration rental service. In 2015 Antonella Dalle Zotte takes over the scientific direction of the laboratory.
