In this sense, in the present article, the role of the presence of hydrogen bonds on the mechanical properties of a set of mortars (weak, intermediate, and strong) is advanced. The mechanical performances were the compressive, flexural, and adhesion strengths. The results revealed linear ...
The mechanical properties of the hydrogel may be enhanced by cross-linking the polymer chains with hydrogen bonds and microcrystals. The mechanical properties of the hydrogel were not only increased with the increase of freeze-thaw times but also improved by the addition of crosslinking agent CB[7...
Ingestion of MPs by living organisms may increase exposure to HOC levels. The key mechanisms for the sorption of HOCs onto MPs are hydrophobic interaction, electrostatic interaction, π–π interactions, hydrogen bonding, and Van der Waals forces (vdW). Polymer type, UV-light-induced surface ...
Additionally, the photoluminescence measurements reveal that deep-level emissions caused by defects located deep in the band gap can be reduced. This would have a positive impact on the UV light emission efficiency of ZnO devices like LED. Subsequently, based on those results, the possible growth ...
Answer and Explanation:1 The answer is B. Vapor Pressure. Vapor pressure is the pressure exerted by gas molecules or vapors on a surface of a liquid. If the...
Clay minerals such as kaolinite, smectite, chlorite, micas are main components of raw materials of clay and formed in presence of water. A large number of clays used to form the different structure which completely depends on their mining source. They ar
The structure and strength of the hyphae are given by chitin in the cell walls24,25. Chitin is a hard, inelastic linear polymer26 bonded by hydrogen bonds, which gives it rigidity along its chain27. This bonding allows chitin to possess superior tensile strength, even higher than that of ...
The basic properties of obtained foams, e.g., apparent density, brittleness, water absorption, compressive strength, flammability were examined. Afterwards, both series of foams (C_0t and CU_0t) were subjected to degradation in the climatic chamber, acting on samples of foams a defined ...
In powder materials containing proteins and polysaccharides, the presence of water can cause the formation of new hydrogen bonds and the hydrolysis of the compound into simpler substances [28]. High moisture content promotes a reduction in bulk density. Waste from the poultry industry (poultry ...
Water-based nanofluids were prepared using nanoparticles at different concentration ratios. Briefly, GO-TiO2-Ag THNp were suspended in deionized water at a concentration of 0.5 wt%. The nanofluids were then sonicated using an ultrasonic probe sonication for 1 min and then followed by water bath ...
