“…In Figure 4(b), the symmetrical deformation vibration peaks of CH 3 were at 1377 cm −1 and the stretching vibration peaks of CO were at 1713 cm −1 . Compared with Figure 4(c), in Figure 4(d), the peaks at 2849 and 2915 cm −1 corresponded to the reaction products of the symmetric (ν s [CH 2 ]) and asymmetric (ν as [CH 2 ]) stretching vibrations of methylene groups, respectively 42 . And the scissoring and rocking modes of the methylene group were observed at 1462 and 716 cm −1 , respectively, which indicated that AgSt was composed of a triaxial system with two chains per unit cell 43 .…”

In this article, the superhydrophobic and antibacterial surface on the cotton fabric were fabricated with the UV curable waterborne coatings, the silver nanoparticles, and the stearic acid. The cotton fabric coated with silver stearate was obtained by immersing in a mixture of sodium hydroxide and then modified by stearic acid. Results showed that the water contact angle on the surface of the fabric was 157.6°. The micromorphology and chemical ingredients of the surface of the coating were studied by scanning electron microscope, Fourier transforms infrared spectroscopy, and X photoelectric spectrometer. Results showed that the immersion resulted in a double decomposition reaction and with the modification of the stearic acid, the silver stearate was formed on the surface, which provided a rough surface required for super‐hydrophobicity. And the acid and alkali resistance test, water‐resistance test, and antibacterial activity test indicated that the coating had good acid and alkaline resistance, water‐resistance, and antibacterial properties.

“…The agar‐well diffusion method was used to determine the antibacterial activities of pyrrolidinyl alcohols and amines against four foodborne pathogenic bacterial strains, namely, Salmonella enterica subsp. enterica serovar Typhimurium ATCC 4028, E. coli O157:H7 ATCC 33150, S. aureus ATCC 25923, and L. monocytogenes ATCC 19118 following the method described in the literature . The bacterial strains were suspended and activated (10 5 –10 6 cfu/mL) twice in Nutrient Broth (Merck, Germany) after incubation at 37°C for 24 h. Autoclaved Nutrient Agar (Merck, Darmstadt, Germany) was inoculated with each fresh bacterial strain at 43–45°C and poured in petri plates.…”

Three new tricyclic pyrrolidinyl alcohols and three tricyclic pyrrolidinyl amines were synthesized, and the antibacterial activities of these compounds were tested against Salmonella enterica subsp. enterica serovar Typhimurium, Escherichia coli O157:H7, Staphylococcus aureus, and Listeria monocytogenes. All tested pyrrolidinyl alcohols and amines showed antibacterial activity to the tested pathogens, but this activity was dependent on the final concentration of the tested compound, and the structure of these compounds were also important for this antibacterial activity. Of the tested compounds, (2R)‐2‐(octahydro‐4,8‐ethanocyclohepta[c]pyrrol‐2(1H)‐yl)‐2‐phenylethanamine (2c) was the most effective compound among the tested pyrrolidinyl alcohols and amines. This study shows a good example of finding new antimicrobials in order to control pathogenic bacteria.

“…MG bands at 2918 cm −1 and 2849 cm −1 resulted from, respectively, asymmetric and symmetric stretching vibration of methylene [24,30], indicating successful loading of sodium stearate ions into the garnet. The bands at 1434, 1464, and 1558 cm −1 of sodium stearate were attributed to vibration absorption of methyl and methylene, and asymmetric stretching vibration of the carboxylate group, respectively [30][31][32]. When sodium stearate was grafted onto the garnet, those bands interacted with the band at 1445 cm −1 , leading to a band shift, demonstrating chemical adsorption of sodium stearate in garnet.…”

The present study investigated the tribological performance of epoxy (EP) matrix composites enhanced with natural garnet. The garnet was surface-modified with sodium stearate for optimal performance. Composites comprising different contents and particle sizes of modified garnet (MG) were prepared with a mixture of EP and MG. The sodium stearate-bonded garnet and EP formed a stable structure. Tribological performance was measured by a ball-on-plate apparatus under permanent dry sliding conditions and a wear track was obtained by an optical profilometer. The wear mechanism was explored by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) images. Wear test results showed that the coefficient of friction for all EP/MG composites decreased compared with that for neat epoxy. The results also indicated that the addition of MG can evidently improve the tribological properties of EP matrix composites.
