Is it possible to convert highly specialized research in the field of computational spectroscopy into robust and user-friendly aids to experiments and industrial applications? What kind of tools should be created to increase the interactions between researchers with different backgrounds and push towards new frontiers in computational chemistry? The outstanding advances in computational spectroscopy and the wide availability of computational and analytical tools are paving the route toward the study of problems that were previously difficult or impossible to solve and enable the imagination of even more ambitious targets for fundamental and applied research. The combination of new computer- and data-centric technologies is transforming data analysis from an uncommon and retrospective practice into a proactive process of strategic decision and action. This paper starts from these premises and proposes a perspective for a new cyberinfrastructure aimed at integrating developments in theory, algorithms and software with new tools for workflow management, data mining and visualization. We make a case for this approach by means of a few examples that deal with unmanageable types of data in molecular modelling and results obtained using different unsupervised learning algorithms.

Functional magnetic resonance imaging (fMRI) has dramatically advanced non-invasive human brain mapping and decoding. Functional near-infrared spectroscopy (fNIRS) and high-density diffuse optical tomography (HD-DOT) non-invasively measure blood oxygen fluctuations related to brain activity, like fMRI, at the brain surface, using more-lightweight equipment that circumvents ergonomic and logistical limitations of fMRI. HD-DOT grids have smaller inter-optode spacing (~ 13 mm) than sparse fNIRS (~ 30 mm) and therefore provide higher image quality, with spatial resolution ~ 1/2 that of fMRI, when using the several source-detector distances (13-40 mm) afforded by the HD-DOT grid.

Microtiter-plate-based systems are unified platforms of high-throughput experimentation (HTE). These polymeric devices are used worldwide on a daily basis-mainly in the pharmaceutical industry-for parallel syntheses, reaction optimization, various preclinical studies and high-throughput screening methods. Accordingly, laboratory automation today aims to handle these commercially available multiwell plates, making developments focused on their modifications a priority area of modern applied research.

Myofibroblastoma is a rare mesenchymal tumour known for its benign nature but complex diagnostic pathway. A woman in her 40s presented with a painless breast mass, initially reported as a fibroadenoma on ultrasound mammography and as a benign to borderline phyllodes tumour on fine needle aspiration cytology. Contrast-enhanced CT was reported as carcinoma of the breast with Breast Imaging and Reporting Data System (BIRADS)-6.

The novel diiron amine complexes [FeCp(CO)(NHR')(μ-CO){μ-CN(Me)(Cy)}]CFSO [R' = H, 3; Cy, 4; CHCHNH, 5; CHCHNMe, 6; CHCH(4-CHOMe), 7; CHCH(4-CHOH), 8; Cp = η-CH, Cy = CH = cyclohexyl] were synthesized in 49-92 % yields from [FeCp(CO)(μ-CO){μ-CN(Me)(Cy)}]CFSO, 1a, using a straightforward two-step procedure. They were characterized by IR and multinuclear NMR spectroscopy, and the structure of 7 was confirmed through X-ray diffraction analysis. Complexes 3-8 and the acetonitrile adducts [FeCp(CO)(NCMe)(μ-CO){μ-CN(Me)(R)}]CFSO (R = Cy, 2a; Me, 2b; Xyl = 2,6-CHMe, 2c) were assessed for their water solubility, octanol-water partition coefficient and stability in physiological-like solutions.

Chalcones are organic substances that have diverse biological activities and exhibit potential for the treatment of various diseases. The properties of these substances depend on the type and position of the functional group attached to their aromatic rings. As a result, in this work the chalcone (2E)-1-(4-hydroxyphenyl)-3-(4-methoxyphenyl)-prop-2-en-1-one (CHO) was investigated by Raman spectroscopy and computational calculations at high pressures with the objective of analyzing its structural stability.
