“…Taking into account the fact that the halloysite surface is negatively charged at pH 6 [61] (pH used to perform the adsorption process), it seems that in the case of the adsorption of the tested polysaccharides, non‐electrostatic interactions play a determining role in the adsorption process because the non‐ionic polymer is the most strongly adsorbed. It is also noticeable that the carbon and hydrogen amounts are larger in the presence of Tritons and the larger these increases are the longer the surfactant chains (a larger amount of the −OCH 2 CH 2 groups) [56–58] . The adsorption of the polymer‐surfactant complexes (Figure 2, 3 and 4) on the clay mineral surface is responsible for this phenomenon.…”

“…These complexes can adsorbed on the solid surface (Table 1) and cover the solid particles. Taking into consideration the fact that Triton X-100 has 9-10 À OCH 2 CH 2 groups, Triton X-165 -16, and Triton X-405 -35 [56][57][58] thus the smallest stability in the polymer/surfactant/ clay mineral systems is observed in the presence of the heaviest TX-405. This observation is quite interesting because it means that systems containing only pure polymer stabilize aqueous halloysite suspensions much more effectively.…”

The paper presents the colloidal and thermal stability of the three‐component hybrid materials containing halloysite, polysaccharides (alginic acid, cationic cellulose and hydroxyethyl cellulose) and Tritons. TX‐100, TX‐165 and TX‐405 were used as non‐ionic surfactants. Stability and other properties of the hybrid materials were tested by the following methods: UV‐Vis, TGA (thermogravimetric analysis) and DSC (differential scanning calorimetry), CHN (elemental analysis), SEM‐EDX (scanning electron microscopy with energy dispersive X‐Ray spectroscopy) and tensiometry. According to the results with the increasing polymer concentration the colloidal stability of the tested systems also increases. Moreover, the addition of the surfactants causes the increase of polysaccharide adsorption but the colloidal stability of the tested systems decreases due to large weights of formed aggregates. As follows from the thermal analysis, the comparison of the TG/DTG‐DSC curves obtained for the investigated polymers confirms that their thermal decomposition courses have some common features. The obtained results have the application potential in the formation of the materials for the pollutants removal from water and sewages.

“…Previously, CNFs have been functionalized by a variety of covalent and noncovalent chemical processes [8]. Concentrated nitric and sulfuric acids are the most efficient chemical technique for CNF surface oxidation [9][10][11][12][13][14][15][16]. Ros et al oxidized fishbone and parallel CNF by refluxing in concentrated HNO3 and 1:1 mixture of HNO3 and H2SO4 [9].…”

“…As time and temperature increased, the yield of functional compounds reduced. Using a 3:1 ratio of H2SO4 to HNO3, Kaur et al were able to disperse and functionalize CNF by refluxing it at 80 °C for 90 minutes [12]. The acidic treatment of hat-stacked CNF in a 3:1 combination of H2SO4 and HNO3 was described by Sato et al [13].…”

Chicken manure is one of the most widely generated animal waste worldwide. However, waste is the anomaly being used for this organic treasure as it contains all 13 essential nutrients that are used by plants and for the reason, the traditional use of chicken manure is as a fertilizer. It increases the fertility of soil but at the same time, it may give rise to accumulation of heavy metals in soil, greenhouse gas emissions, soil acidification, spreading of diseases, rodents, and pests, etc. Other value-addition processes for the treatment of chicken manure like composting, gasification, pyrolysis, torrefaction, etc., are either costlier or energy intensive. So, we present here a new method to use chicken manure in a very simple and economical way for the fuel cell applications. In this study, carbon nanofibers (CNF) are modified with chicken manure to impart multiple functionalities to their surface, and further the functionalized CNF are explored as an electrocatalyst to speed up the sluggish oxygen reduction reaction kinetics happening at the cathode of a fuel cell. The functionalized CNF contains N (7.40 at.%), O (6.22 at.%), P (0.30 at.%), S (0.02 at.%), etc., elements as revealed by the EDX and FTIR studies. FESEM and XRD studies confirmed that the morphology of CNF remained intact after their treatment with chicken manure. The modified CNF exhibited a higher electrocatalytic activity (onset potential: - 0.0756 V; limiting current density: 2.69 mA cm-2) as compared to the pristine CNF. The effects of dispersion (with Triton X-100) on the chicken manure-based functionalization of CNF are also investigated. This preliminary study on novel usage of chicken manure for the fuel cell applications will usher the advanced ways of treating different environmental wastes.
