Production of bio-oil by hydrothermal liquefaction of biomass is a promising way to achieve several sustainable development goals: renewable energy, proper waste treatment, reduction of greenhouse gas emissions, etc. For the wide application of bio-oil in industry and transport, it is important to study its molecular composition. However, the molecular composition of bio-oil is almost as complicated as that of natural petroleum, and despite the considerable amount of research, it is not fully understood. Here, we applied high-resolution mass spectrometry, collision induced dissociation, the isotope (H/D and 16O/18O) exchange approach, and other analytical techniques in order to obtain chemical information about individual molecules of bio-oil. We proved the presence of different nitrogen functionalities including quaternary nitrogen in the bio-oil. Analyzing MS/MS spectra of individual compounds, we proposed possible structures of individual molecules of bio-oil.

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

Cyanide containing wastewater can cause livestock death and reduce agricultural production and electrochemical reduction of cyanide (CNRR) is a promising way to eliminate its harm and turn waste into valuable products. However, the reaction mechanism and function of electrocatalysts for CNRR have not been fully understood yet. Herein we identify a two-dimensional (2D) conductive copper-organic ...

Colloidal semiconductor nanocrystals have emerged as promising materials for next-generation light-emitting diodes (LEDs) owing to their solution processability, tunable emission wavelengths, narrow emission linewidths, and high photoluminescence quantum yields. Among them, anisotropic nanocrystals, including one-dimensional nanorods (NRs) and two-dimensional nanoplatelets (NPLs), offer additional opportunities for controlling transition dipole moment orientation and light out-coupling efficiency. These ...

The use of hydrophobic deep eutectic solvents (DESs) as extractants for metal ion separation is largely due to the ease of their preparation and the possibility of modifying them depending on the composition of the metal mixture to be separated. However, the most common approach to DES modification involves the replacement of the extractant, while ...

Two voluminous polymer silver(I) salts of perchlorinated dodecoborate clusters, {[(Me2CO)Ag(μ-Me2CO)2Ag(Me2CO)][μ-B12Cl12]}n (1) and {[DMFAg(μ-DMF)2AgDMF][μ-B12Cl12]}n (2) were synthesized. The 35Cl nuclear quadrupole resonance (NQR) spectroscopy supplemented with the X-ray diffraction data was applied for identifying and analyzing noncovalent interactions Cl···X in these salts. Whereas in X-ray diffraction, noncovalent interactions are associated with the presence of the shortened ...

Despite the well-established importance of chalcogen bonding in crystal engineering and supramolecular chemistry, experimental charge density data for TeII-centered chalcogen bonds have remained entirely absent, leaving the electronic nature of these interactions uncharacterized at the level of directly measured electron density. Here, we report the first high-resolution X-ray diffraction (HRXRD) study of TeII-centered chalcogen bonds, ...

Off-stoichiometric boron-doped chemically complex intermetallic alloys (CCIMAs) have recently emerged as a new avenue for overcoming the low temperature brittleness of ordered superlattices. However, their behavior at high temperatures remains unexplored. In this study, a novel (Ni39.6Co29.3Cr10Al15.8Ta3.3Nb2)98.5B1.5 CCIMA was prepared and its oxidation resistance over a wide temperature range (500 °C–950 °C) was studied. The ...

We report a high-performance implementation of the resolution-of-the-identity Hartree–Fock method that fully exploits the permutational symmetry of three-center electron repulsion integrals (ERI). The present implementation adopts a hybrid MPI+OpenMP parallelization strategy. Two different algorithmic approaches (with and without the pre-transformation of ERIs) are compared. A custom data layout introduced previously is employed. Designed to efficiently ...

The development of lead sulfide (PbS) quantum dot (QD) photodetectors for short-wave infrared (SWIR) applications has been fundamentally limited by the thermodynamic instability of large PbS QD facets, which leads to aggregation and epitaxial fusion. In this work, robust thermodynamic stabilization was achieved by introducing methylammonium chloride (MACl) in PbS QD surface passivation, as validated ...

This paper is dedicated to the concept of philosophical analysis in work of three classics of analytic philosophy: Ryle, Strawson and Wittgenstein. These philosophers, as many in their generations, believe that philosophical analysis does not bring forth new knowledge, it simply brings clarity into our ways of speaking. However, despite the main stream of analytical ...
