Biorecycling of wood includes many different processes aimed at the complete utilization of the main and by-products. The complete isolation of C5 and C6 sugars from wood and their further use is currently attracting attention worldwide. The C5 sugars can be catalytically converted directly into furfural or into monosaccharides’ aqueous solution for further hydrolytic treatment. The resulting lignocellulose can be used in thermochemical pyrolysis (350-400°C) for the synthesis of levoglucosan. The biochar formed during pyrolysis and the liquid residue after the isolation of levoglucosan are by-products and can be used as precursors to obtain valuable products – activated carbon composites for supercapacitor electrodes and catalysts in fuel cells.

Human security remains a topical issue, especially on the country borders where temporary houses are often used. Optimally, people should be provided with ordinary, habitable, easy-to-build, possibly portable buildings and ballistically protected. However, there is a lack of studies addressing ballistic building materials for the walls. In the scope of this study, ten ballistic materials: sand walls, concrete, steel plates, ceramic, glass fibreboards, wood (plywood, cross-laminated timber), ultra-high molecular weight polyethylene (UHMWPE) boards, aramid boards, carbon fibre boards, and gypsum plasterboard are reviewed, and their wall constructions are compared. This paper aimed to analyse bulletproof materials and to nominate the best bulletproof walls according to three required aspects - price, thermal transmittance, and weight. This is a review article that could help stakeholders to choose the appropriate ballistic material for high-risk applications.

In this study, we used Stereolithography to develop tricalcium phosphate-based scaffolds. The feedstock for the process consisted of a UV-curable resin, synthetic tricalcium phosphate, and silicon oxide. The viscosity and curability of the resins are carefully controlled to enable the fabrication of complex-shaped scaffolds. Following stereolithography, the ceramic-resin scaffolds were heat treated. The first step was debinding process followed by a sintering step. The resulting sintered samples underwent microstructure, chemical, and mechanical analysis to assess their properties. The optimized samples were then subjected to biodegradability and cytotoxicity tests to evaluate their suitability for use as tissue engineering scaffolds.

The topic of the research article is the development of an evaluation method of an ergonomic-based test battery to evaluate the ease of use, cutting solution and materials of the combat clothing uniform of defence forces, which can be added to the procurement sample evaluation system. Evaluation of the ergonomics of the new combat clothing uniform was performed using military recruits who completed a Military Pentathlon test battery in outdoor conditions with eight different obstacles. The comfort and fit of the tested clothes were evaluated using observation and questionnaire. This process was carried out using 47 military personnel of the Estonia Defence Force battalions. Each soldier was measured manually with a tape measure to clarify clothing size and to characterize the test population. From the measurement results, test persons 14, whose measurements corresponded to the size number and height of the two sample combat clothing, were selected. With selected 14 test persons was performed testing of combat clothing outside, which were carried out on the test battery of ergonomic. Their performance evaluated by two external observers with relevant education. After completing the test battery, both, test subjects and observers individually filled the closed-ended questionnaire with a 3-point attitude scale with emoticons about the ergonomic aspects of the combat clothing. The analysis of the answers to the questionnaire showed that the opinions of both the subjects and the observers agreed. Among the 14 subjects, 11 were conscripts. This shows that if a corresponding test track has been prepared for testing the ergonomics of clothing, then giving an assessment to the clothing is understandable to the respondent. The method also facilitates the verification of clothing criteria as performance-based procurement assessment. Not a separate test battery was prepared during this study. This helps to save costs, as it does not require the construction of a specific test battery and is available to many military recruits.

A major function of resin is to provide defense against external attacks by releasing the resin flow on the attacked or damaged area. Nonetheless, the leakage of the resin on the surface can have a negative aesthetic and economic impact on wood material. The aim of this study is to investigate which treatments affect the chemo-physical properties of the resin in order to hinder the exudation on wood surface during service. To achieve a thickening of the resin, it is necessary to remove the volatile turpentine, and several studies have been carried out in this direction, providing useful information about this process. The heat treatment at different temperatures, 60°C, 100°C and 150°C, respectively, gives different mass losses, thus confirming that the turpentine can remain for long time in the resin, and the changes in structural, morphological, and chemical properties are affected by the temperature. FTIR spectroscopy, before and after thermal treatment, does not show major changes in chemical structures. However, from the samples analyzed with UHPLC-DAD-MS significant differences of the ratios of 20 compounds were observed, which characterize possible chemical reactions, such as decomposition, dehydrogenation, oxidation and isomerization. After heat treatment, the glass transition temperature of resin increased. Color changes are evident: resin becomes darker with increasing the temperature of treatment, apart from the resin heated at 100°C. The chemical changes in the composition of the resin caused by heat treatment need further investigation.

This article presents an investigation into the impact of High Pressure Torsion Extrusion (HPTE) on the microstructural features, hardness and hydrogen storage, focusing on pure magnesium. HPTE is a modern mechanical nanostructuring technique that can refine the microstructural properties and subsequently affects the mechanical and functional properties of the materials. Two HPTE regimes were used in this study: (1) Direct Extrusion without rotation (DE), and (2) an extrusion speed of 6 mm/min along with a rotational speed of 1.8 rpm (v6w1.8). One sample in as-received conditions was also tested as a reference. Results showed increased hardness in the material after HPTE processing, with the DE sample reaching 60 HRB and the v6w1.8 sample exhibiting a gradient distribution of hardness from 71 to 83 HRB. X-ray diffraction analysis revealed significant microstructural refinement in the v6w1.8 sample. Results of hydrogenation kinetics showed that the DE sample absorbed up to 1.2 wt.% of hydrogen, while the v6w1.8 sample displayed 7.2 wt.% of hydrogen absorption, approaching the theoretical hydrogen storage capacity for magnesium (7.6 wt.%). These findings highlight the positive effects of HPTE on microstructural refinement and hydrogen storage, showcasing its potential for advancements in materials science and hydrogen-based energy technologies.

The processes of concentration of dilute solutions of sulfuric acid (H 2 SO 4 ), in particular hydrolytic sulfuric acid for the production of pigment titanium (IV) oxide, were analyzed. It is proposed to concentrate solutions of Н 2 SO 4 by evaporation in direct contact of acid droplets with hot industrial exhaust gases. The mathematical model of the evap-oration of Н 2 SO 4 drops in a hot gas stream, which used for the calculations, makes it possible to calculate the mass, temperature, velocity, and coordinates of the drop at any time with sufficient accuracy. However, the calculations are difficult, cumbersome and require multiple processing of large data sets. Therefore, the aim of the article was to approximate the calculated technological parameters of sulfuric acid droplet evaporation by obtaining simple mathematical dependencies. The mathematical dependences of the mass transfer coefficient and the distance traveled by a drop of Н 2 SO 4 during evaporation on air temperature and drop diameter were obtained. It has been established that technologically expedient evaporation of Н 2 SO 4 drops with a diameter of ≤ 0.5·10 -3 m in traditional devices leads to significant droplet loss, increased corrosion of equipment, etc. So, in order to practically implement the technol - ogy of evaporation of HSA solutions with industrial exhaust gases, it is necessary to change the technological mode of operation of the evaporator and the design of the main device. It is proposed to use the obtained results to study the methods of intensification of the evaporation process, selecting a modern mass transfer apparatus, developing a technology for utilizing hydrolytic sulfuric acid and producing pigment titanium (IV) oxide.
