The light‐induced control in the fabrication of materials is a field in continuous development. So far, photo‐induced processes have been used mostly for organic polymeric materials. However, there is a recent, increasing interest in exploring the possibility of using these techniques to induce the precipitation of inorganic materials. This perspective paper outlines the main principles of the light‐induced precipitation of inorganic materials, focusing on the recent papers published in this field. The description of the mechanisms and the materials involved in these light‐induced processes highlight their many possibilities and future challenges, which could pave the way for significant advancements in this exciting technology.

An exploratory machine learning (ML) classification model that seeks to examine CaCO3 polymorph selection is presented. The ML model can distinguish if a given peptide sequence binds with calcite or aragonite, polymorphs of CaCO3. The classifier, which was created using SVM and amino acid chemical composition as the input descriptors, yielded satisfactory performance in the classification task, as characterized by AUC = 0.736 and F1 = 0.800 in the test set. Model optimization revealed that tiny, aliphatic, aromatic, acidic, and basic residues are essential descriptors for discriminating aragonite biomineralization peptides from calcite. The presented model offers valuable insights on the significant chemical attributes of biomineralization peptides involved in polymorph binding preference. This can deepen our understanding about the biomineralization phenomenon and may be deployed in the future for the creation biomimetic materials.

During the preparation of ‘tuibur’, a non-cigarette tobacco product of Northeast India (NEI), tobacco ash generated from the tobacco stalk (stem, petiole, and midrib) is haphazardly dispersed into the soil. Powder x-ray diffraction (PXRD) analysis indicated the presence of calcite, potassium chloride, potassium aluminum silicate, magnesium calcite and calcium silicate hydrate crystallites in the tobacco ash. C, O, Mg, Al, Si, Cl, K, Ca, Fe, P and Hg species present at the surface of tobacco stalk ash were studied using x-ray photoelectron spectroscopy (XPS). Inductively coupled plasma atomic emission spectroscopy (ICP-OES), in a complementary manner, indicated the content of selected heavy elements (essential and non-essential).Scanning electron microscopy combined with energy dispersive X-ray spectroscopy (SEM-EDS) revealed aggregates of sub-micronorganic tobacco ash particles along with inorganic nano-crystalline particles in the tobacco ash. Raman spectral features revealed the presence of calcite and aragonite, the polymorphs of calcium carbonate, in the tobacco stalk ash samples. Haphazard disposal of tobacco waste such as tobacco ash may lead to environmental degradation.
