“…By contrast, the spectrum of dolomite contains more bands than calcite and is probably due to a reduction of lattice symmetry as a result of the replacement of half the Ca 2+ with Mg 2+ ion layers. These bands are all lattice modes similar to the ones found in calcite [20,28,39]. The mid-infrared spectra of the carbonate minerals tend to look similar considering that they involve mainly internal vibrations of the CO 3 2À ion [10].…”

“…The mid-infrared spectra of the carbonate minerals tend to look similar considering that they involve mainly internal vibrations of the CO 3 2À ion [10]. However, the farinfrared spectra seem to be more discernible since they entail lattice vibrations and any substitution of one cation for another will result in significant peak shifts [28].…”

“…In a majority of the literature reports, spectra have been obtained using a transparent polyethylene pellet/disk in transmission mode [28]. An alternative method which is more convenient for directly probing the sample without requiring significant time for sample preparation is the technique of attenuated total reflectance (ATR).…”

“…In addition, many of the mineral components of shale rocks are expected to exhibit characteristic absorption bands in the FIR region. Although there is extensive literature on the vibrational spectroscopy of minerals [20,28], to our knowledge the application of FIR for the characterization of shales has to date received very little or no attention.…”

“…However it becomes of limited use for structural investigation of inorganic compounds, such as metal oxides or salts, which are inactive in the MIR region. FIR offers great advantages in the characterization of those inorganic compounds [51][52][53][54], as well as coordination complexes [55], lattice vibrations [56,57], hydrogen bonds [58,59], and the skeleton vibration of ring molecule [58], due to the lower energy in the FIR than the MIR spectral region. Just as with MIR, FIR analysis also suffers from the interference of water vapor in the air especially in low frequency [60,61].…”

Catalytic aldose isomerization to ketose is an important reaction for the utilization of cellulosic biomass. However, a fundamental understanding and knowledge base involved in this reaction remains lacking in the literature. In this chapter, we provide a focused review of the most studied solvent-based catalytic system involving metal halides for glucose isomerization to fructose and further to 5-hydroxymethhylfurfral (5-HMF). Results from studies by different physical techniques are critically reviewed. A differentiation of the coordination chemistry of different metal chlorides obtained by various physical techniques is established to rationalize the drastically different catalytic pathways by the metal chloride catalysts. The performance of metal chloride catalysts for the isomerization of aldose to ketose is found to correlate with their coordination chemistry. Solvents play an important role in determining the coordination structures for the metal ions, which critically affect the catalysis of the metal chloride precursors. Undesired side products are related to the reaction pathways corresponding to the nature of the coordination of metal ions with different oxygen sources in the substrates and the products.

Artificial intelligence promotes the development of mineral/rock automatic recognition technology to reduce labor costs and reliance on personal experience. With instrument digitization, image recognition has played an increasingly important role. This review focuses on the image sensing system applied to mineral/rock identification and redivides this system into a sensing module, an imaging module, and an information processing module. The sensing and imaging mechanisms are summarized via technologies of sensing, imaging, and display. The information processing is classified into single‐modal or multimodal recognition. This review analyzes the limitations of single‐modal recognition and discusses the advantages and significance of multimodal recognition. The challenges of current mineral/rock identification are concluded, such as public database, multimodal learning, and portable sensing system. The interdisciplinary sensing technologies are discussed, and application feasibility is explored. This review aims to provide a reference for the research community in automatic mineral/rock identification and sensing system optimization.
