Special Issue Information

Dear Colleagues,

Vibrational spectroscopy instrumentation represents a versatile and convenient method for material characterization, with cost-effective and user-friendly solutions. Variants of Raman and infrared techniques have simplified or completely removed the need for sample preparation, making them available to a wide variety of end-users, ranging from academics to industry professionals.

This Special Issue focuses on highlighting the suitability or indispensability of vibrational spectroscopy to reveal aspects of material properties/behavior over different length scales down to the nanometer scale. We invite contributions, employing either one or a combination of such techniques, which elucidate the behavior of a material, possibly complemented by techniques based on different operating principles. Contributors should evaluate their results with respect to the different length scales to which the techniques used are sensitive. Innovative variants (like transmission or spatially offset Raman, photothermal infrared), surface- or tip-enhanced variants (SERS, TERS, etc.), combinations with other types of microscopies (e.g. AFM-Raman, AFM-IR, SEM-Raman) are also welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Although, the use of sensors is increasing in a wide range of fields with great success (e.g., food, environment, pharma, etc.), their uptake is slow and lower than other innovations. While the uptake is low, some users, producers, and service industries are continuing to benefit from the incorporation of technology in their business. Among these technologies, vibrational spectroscopy has demonstrated its benefits and versatility in a wide range of applications. Both conventional near-infrared (NIR) spectroscopy and hyperspectral imaging (HSI) systems are two of the main techniques utilized in a wide range of applications in different fields. These techniques use the NIR region of the electromagnetic spectrum (750–2500 nm). Specifically, NIR-HSI systems provide spatial information and spectral data, while conventional NIR spectroscopy provides spectral information from a single point. Even though there is a clear distinction between both techniques in terms of their benefits, confusion still exists among users about their similarities and differences. This paper provides a critical discussion of the main advantages and limitations of both techniques, focusing on food science applications. Full article
