L’identification des composés à base de carbone, bien que difficile, est une source d’information essentielle dans de nombreuses études archéologiques et paléontologiques. La diffusion Raman de rayons X est une méthode de spectroscopie sur synchrotron qui permet d’identifier des signatures organiques, de retracer l’origine chimique des systèmes étudiés et de comprendre l’altération des composés organiques dans le temps.

Abstract:

This article reviews recent advances in Raman spectroscopy its types and its applications, from the perspective of pharmaceutical analysis. The emerging concepts enable rapid non-invasive analysis of pharmaceutical formulations and could lead to many important applications in pharmaceutical settings, including quantitative bulk analysis of intact pharmaceutical tablets in quality and process control. Raman spectroscopy is particularly useful as a screening tool for quick evaluation of chemicals and pharmaceuticals since it is simple, non- destructive and information-rich.

Abstract:

Fruit juice and wine are important beverages that are consumed all over the world. Due to their constantly increasing demand and high value, fruit juice and wine are one of the most frequent targets of adulteration. Since adulterated foods are proven to have harmful effects on health, several approaches have been utilized for the detection of fruit juice and wine adulteration. Based on the requirement for sample destruction, analytical techniques to assess food authenticity can be classified into 2 main categories, i.e., destructive and non-destructive techniques.

In favorable cases these spectroscopic techniques enable, beyond a mere general characterization, the conclusive identification of selected minerals.

Abstract Hidden defects can seriously affect the insulation performance of cables and pose safety hazards. In this article, a novel Non-Destructive evaluation technique for insulation materials based on terahertz time-domain spectroscopy technology is proposed. Firstly, terahertz time-domain spectroscopy technology was used to perform reflective scanning on insulation materials. Various imaging algorithms were used to image terahertz defects. The results showed that the maximum imaging and peak to peak time imaging were effective. At the same time, bilateral filtering was used to process terah

Abstract:

Food detection technologies play a vital role in ensuring food safety in the supply chains. Conventional food detection methods for biological, chemical, and physical contaminants are labor-intensive, expensive, time-consuming, and often alter the food samples. These limitations drive the need of the food industry for developing more practical food detection tools that can detect contaminants of all three classes. Raman spectroscopy can offer widespread food safety assessment in a non-destructive, ease-to-operate, sensitive, and rapid manner. Recent advances of Raman spectroscopic methods furt

Abstract:

Given its huge economic, nutritional, and social value, extra virgin olive oil (EVOO) is an essential food. This flagship product of the countries bordering the Mediterranean basin is one of the most frauded products worldwide. Although traditional chemical analyses have demonstrated to be reliable tools for olive drupes and EVOO quality assessment, they present several drawbacks; the urgent need for fast and non-destructive techniques thus motivated this review. Given the lack of comprehensive reviews in the literature, our first aim was to summarize the current knowledge regarding applying s

Abstract:

We review our recent experimental results on the non-destructive quantum-state detection and spectroscopy of single trapped molecules. At the heart of our scheme, a single atomic ion is used to probe the state of a single molecular ion without destroying the molecule or even perturbing its quantum state. This method opens up perspectives for new research directions in precision spectroscopy, for the development of new frequency standards, for tests of fundamental physical concepts and for the precise study of chemical reactions and molecular collisions with full control over the molecular quan

Abstract:

Traditional wet analytical method such as the gravimetric, Kjeldahl or Walkley-Black method are still the most widely used for determining the organic matter (OM), moisture and notal nitrogen (T–N) content of soils. However, these are time-consuming, high in cost and labour intensive as well producing harmfull pollutants making the method undesirable for field measurement. Over three years we have been working on the development of a non-destructive on-site analyser for measuring OM, moisture and T–N. In this research we investigated the possibility of using near infrared (NIR) spectroscopy fo

Abstract Foodborne pathogenic bacteria detection is an important work, the traditional laboratory identification method, will cause irreversible damage to the sample, and the detection cycle is long. Compared with traditional biological detection methods, the greatest advantage of terahertz spectroscopy detection is that it can do non-destructive detection of samples, and terahertz spectroscopy technology, combined with computer systems, can reduce analysis time, improve recognition accuracy, and maximize the extraction and mining of effective information in the spectrum.

Abstract Terahertz time-domain spectroscopy (THz-TDS) provides a non-contact, non-destructive method for evaluating different materials and their properties. This short review discusses the commonly used numerical models for the non-destructive estimation of thickness, refractive index, surface and interface roughness of paints, thermal barrier coatings, and polymer coatings using THz-TDS in the reflection geometry. To demonstrate the applicability of these models, we used paint layers on metallic substrates and extracted different paraments by fitting the experimental THz-TDS data. We conclud

The 1960s saw the emergence of plastic as an indispensable component in various fields, including art and design. Acrylonitrile-butadiene-styrene (ABS) is widely used by artists and designers for a range of applications including sculptures and decorative pieces. Consequently, the necessity to conserve ABS from deterioration is a crucial issue in the field of cultural heritage preservation. Many studies have highlighted the criticality of the stability of the polybutadiene component when exposed to light. We propose a new multimodal spectroscopic approach to assess the conservation status of p

Diffusion of nitrogen implanted in tungsten and molybdenum single crystals has been investigated at temperature about 0.3 Tm (Tm is the melting point). Existence of several dopant atom fluxes is found in subsurface region of the ion implanted material. The diffusion coefficients of the nitrogen connected with the radiation damages and that with the bulk diffusion mechanism are determined. Change of the nitrogen surface concentration has been measured by Auger electron spectroscopy. Initial distribution of the nitrogen and diffusion profiles for various annealing time have been determined by se

Abstract:

Watermelons are in high demand for their juicy texture and sweetness, which is linked to their soluble solids content (SSC). Traditionally, watermelons have been sold as whole fruits. However, the decline in the mean size of households and the very large size of the fruits, together with high prices, mainly at the beginning of the season, mean that supermarkets now sell them as half fruits. For consumers, it is important to know in advance that the fruits that they are purchasing are of a high quality, based not only on external flesh colour but also on sweetness.
