Nano Additives in Cashew Nut Shell Liquid Biodiesel and Environment Emissions of Diesel Engine

The developing countries are using non-edible oils for the production of biofuels, additives, or alternate fuels. The research article focused on the behavior study and analysis of cashew nut shell liquid (CNSL) biodiesel obtained by processing the cashew nut shell liquid. The work is carried out to derive the thermal-cracked (TC) -CNSL oil from Cardonal in the temperature range l50℃ to 400℃. The chemical functional groups are studied using Fourier-transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GCMS) techniques. The TC-CNSL blended fuel performance is compared with diesel and neat biodiesel (B-100). The physicochemical properties of diesel, CNSL, and TC-CNSL biodiesel are estimated based on American Society for Testing and Materials (ASTM) standards. The 50 parts per million (ppm) Cerium Oxide Nanoparticles are added with TC-CNSL-B25, TC-CNSL-B50, TC-CNSL-75, and TC-CNSL-BJOO and processed in a single stroke diesel engine working at constant speed 1500-rpm. The blended fuel is analyzed based on environmental emission parameters in the diesel engines. The carbon monoxide (CO), carbon dioxide (CO2) hydrocarbon (HC) emissions of B-100 are reduced by 40.5%, 60.9%, and 30.7% respectively in comparison to diesel, at full load. The nitrogen oxide (NOx) emissions are increased by 13.26 % in B-100 in comparison to diesel, at full load. The smoke density is also observed decreasing in B-100 in comparison to diesel.

Utilization of Soapberry as a Natural Surfactant in Cashew Nut Shell Liquid Bioinsecticide Formulation in Soybean Pest Management

The demand for soybean has been steadily increasing year after year. Pests are one of the most significant barriers to increasing soybean production. The goal of this study was to determine what concentration of soapberry fruit extract to use as an adjunctive ingredient in cashew nut shell liquid (CNSL) formulations to obtain the best pest control effect and soybean growth and yield. This study used a randomized complete block design with a single factor: soapberry extract concentration. The research included four treatments: application of CNSL formulations containing 4%, 3%, 2%, and 0% soapberry extract, application of CNSL formulations containing 1 g/liter detergent, synthetic pesticides (Fastac 1-2 liters/ha), and no pesticides as a control. Insecticide applications were effective against grasshopper and pod-sucking bugs in soybean cultivation; the CNSL with 3%, 4% soapberry and the CNSL with detergent had effectiveness comparable to the synthetic insecticides. Soybean growth was unaffected by any of the CNSL formulations or synthetic insecticide applications. However, using a CNSL formulation with 4% soapberry increased soybean yield as much as using a synthetic insecticide; it did not differ significantly from using a CNSL formulation with detergent. The soybean yield was highest in the CNSL formulation with detergent.

Sustainable multifunctional phenolic lipids as potential therapeutics in Dentistry

Phenolic lipids components of the cashew nutshell liquid (CNSL) have molecular structures capable of chemical signalling that regulate gene expression, metabolism and inflammation. This study sets out to assess how CNSL derivatives impact oral bacteria, from an antibacterial and anti-collagenolytic perspective, as well as its biocompatibility with dental pulp stem cells. Two hemi-synthetic saturated CNSL derivative compounds were selected (LDT11-Anacardic Acids-derivative and LDT409-cardanol-derivative). Bacteriostatic activity was tested against Streptococcus mutans and Veillonella parvula. Antimicrobial capacity against preformed S. mutans biofilms was investigated using a collagen-coated Calgary Biofilm Device and confocal microscopy. Clostridium histolyticum, P. gingivalis and S. mutans biofilms were used to assess anti-collagenolytic activity. Biocompatibility with human dental pulp stromal cells (HDPSCs) was investigated (MTT for viability proportion, LDH assays for cell death rate). LDTs inhibited the bacterial growth, as well as partially inhibited bacterial collagenases in concentrations higher than 5 μg/mL. Dose–response rates of biofilm cell death was observed (LDT11 at 20, 50, 100 μg/mL = 1.0 ± 0.4, 0.7 ± 0.3, 0.6 ± 0.03, respectively). Maximum cytotoxicity was 30%. After 1 week, LDT409 had no HDPSCs death. HDPSCs viability was decreased after 24 h of treatment with LDT11 and LDT409, but recovered at 72 h and showed a massive increase in viability and proliferation after 1 week. LDTs treatment was associated with odontoblast-like morphology. In conclusion, LDT11 multifunctionality and biocompatibility, stimulating dental pulp stem cells proliferation and differentiation, indicates a potential as a bio-based dental material for regenerative Dentistry. Its potential as a bacterial collagenases inhibitor to reduce collagen degradation in root/dentinal caries can be further explored.

Isolasi dan Karakterisasi Molekuler Gen 16S rRNA Bakteri Lipolitik Asal Limbah Kulit Biji Jambu Mete

Lipolytic bacteria attract great attention to various biotechnology industries because of their enzymatic potential. This study aims to isolate and identify lipolytic bacteria from cashew nutshell waste using the 16S rRNA gene as a molecular marker. Lipolytic bacteria were isolated using serial dilutions and inoculated on lipolytic media. A total of 3 isolates of lipolytic bacteria were obtained from cashew nutshell waste based on screening in LA Rhodamine B. The partial sequence of 16S rRNA gene from LB15 amplified using a pair of primers 63F and 1387R having a size of 1238 bp, while BL6 and BK6 were 1283 bp, respectively. Based on genetic distance analysis and phylogenetic reconstruction, we proposed that LB15 be identified as Burkholderia sp. with 99.92% similarity. In addition, because the 16S rRNA gene sequence similarity of BL6 was 99.87% with Paraburkholderia kururiensis strain 979, BL6 was classified as Paraburkholderia kururiensis. Then, isolate BK6 was identified as Ralstonia sp. with a similarity of 99.53%. The similarity value can be used as a reference in determining the identity of bacteria. A bacterium can be categorized as the same species if it has a similarity value of more than 99%.

Environmentally Friendly Method of Assembly of Cardanol and Cholesterol into Nanostructures Using a Continuous Flow Microfluidic Device

This study shows a viable and straightforward microfluidic method of assembly of cardanol (CA) and cholesterol (CH) into amphiphile nanostructures obtained through a hydrodynamic focusing approach according to which an alcoholic solution of CA and CH is constrained within a two-dimensional lamina shape by two lateral streams of borate buffer solution. The process is performed within glass-made cross-shaped micro-sized fluidic chips specially designed to achieve a laminar regime. CA, distilled from the cashew nut shell liquid, is demonstrated as a surface-active molecule in borate buffer basic medium and when mixed with CH it produces versatile nanovesicles through an in-batch solvent-free process. Compared to this conventional method, the microfluidic route allows operating under continuous flows, with a reduced amount of reagents and at lower experimental temperatures, ensuring no waste formation and the achievement of size-monodisperse amphiphile nanostructures that do not need further steps of purification. Electron microscopy analyses demonstrate that upon increasing CH in the lipid mixture, a switchover from spherical CA micelles to CA/CH mixed closed vesicles occurs. Differential scanning microcalorimetry confirms the formation of vesicular structures and evidences the primary role of CH, which increasingly lowers the temperature of transition depending on its concentration.

Ecotoxicological Evaluation of Products Obtained from Technical Cashew Nutshell Liquid (tCNSL) Proposed as Larvicide to Control Aedes aegypti (Diptera: Culicidae)

The development of new insecticides for vector control that are toxicologically safe and eco-friendly (such as those obtained from industrial by-products) is an important public health concern. Previous research has shown that the obtained tCNSL (technical cashew nutshell liquid) + NatCNSLS (sodium tCNSL sulfonate mixture) emulsion displayed both surfactant properties and larvicidal activity (LC50-24 h 110.6 mg/L). Thus, the emulsion is considered a promising alternative product for the control of Aedes aegypti. The goal of this study was an ecotoxicological evaluation of the tCNSL + NatCNSLS mixture emulsion and its components. In addition, we compared the toxicity of the tCNSL + NatCNSLS mixture emulsion with toxicity data from larvicide currently recommended by the World Health Organization (WHO). Ecotoxicological tests were performed to assess acute toxicity, phytotoxicity, cytotoxicity, genotoxicity, and mutagenicity using Daphnia similis, Pseudokirchneriella subcapitata, Oreochromis niloticus, Allium cepa, and Salmonella enterica serovar Typhimurium. Regarding acute toxicity, D. similis was the most sensitive test organism for the three evaluated products, followed by P. subcapitata and O. niloticus. The highest acute toxicity product was tCNSL. The tCNSL + NatCNSLS mixture emulsion did not show cytotoxic, genotoxic, or mutagenic effects, and showed low acute toxicity to D. similis. In addition, the tCNSL + NatCNSLS mixture emulsion presented a lower or similar toxicological classification to the larvicides recommended by the WHO. Therefore, ecotoxicological tests suggest that the tCNSL + NatCNSLS mixture emulsion can be considered a larvicide environmentally safe way to control Ae. aegypti.

Isolation and Green Methylation of Cardanol from Cashew Nut Shell Liquid

In this work, cardanol was isolated from decarboxylated Cashew Nut Shell Liquid (CNSL) and then methylated using a green reagent, dimethyl carbonate (DMC). The decarboxylated CNSL was obtained from the mechanical press method and followed by heating at 140 °C for 1 hour. Afterward, cardanol was isolated using methanol and ammonium hydroxide, and then extracted with n-hexane. Methylation of cardanol was carried out by the use of DMS and green reagent of DMC, and some variation was done to get the optimum condition, such as variation of the type of phase transfer catalyst (PTC), amount of base K2CO3, the temperature, and time of reaction. It was found that CNSL contains anacardic acid (46%), cardanol (30%), and cardol (23%), while decarboxylated CNSL contains anacardic acid (11%), cardanol (60%), and cardol (19%). The optimum condition of cardanol isolation was obtained by reacting CNSL with methanol and ammonium hydroxide with a volume ratio of 8:5 at room temperature for 2 hours to yield cardanol in 79.01% with 96.59% purity. Furthermore, the optimum condition of green methylation cardanol was achieved at a mole ratio of cardanol:DMC:TBAB:K2CO3 = 5:160:3:3.75 for 10 hours at 200 °C to give methyl cardanol in 82.20% with 96.92% purity.

Amongst, CNS/KOH ratios of 1:1 sample are used for the adsorbent, they are effects of contact time, pH, adsorbent dose, and initial dye concentration on brilliant green (BG) removal efficiency were studied. Moreover, the Langmuir and Freundlich adsorption models consisted utilized to affirm the adsorption isotherms. They are, best fitting for BG experimental equilibrium data was achieved with the Langmuir isotherm, giving a maximum BG adsorption capacity of 243.90 mg/g.

Poly‐cardanol as plasticizer and compatibilizer on styrene butadiene rubber with improved processability and silica dispersion

AbstractNatural products used as plasticizer can inhibit its migration in rubber and improve the dispersion of inorganic power. Herein, styrene butadiene rubber (SBR) was plasticized by poly‐cardanol (PCA) originated from the Friedel–Crafts alkylation without solvent of cardanol which was extracted from abandoned cashew nut shell. Results show that the Mooney viscosity of SBR/PCA compounds decreases from 45.8 to 34.7 and Tg from −52°C to −56.3°C when PCA is added from 0 to 30 phr. Moreover, the elongation at break of SBR contained 30 phr PCA increases by 515% compared with SBR. PCA also shows amphiphilic, which is verified by the improved dispersion of SiO2 in SBR/PCA compounds. The swelling ratio of SBR/PCA/SiO2 vulcanized rubber decreases and the crosslinking density increases. Meanwhile, the elongation at break of SBR70‐40 vulcanized rubber is 17.3%, which is higher than that of SBR100‐40 vulcanized rubber. PCA, acted as plasticizer and compatibilizer, provides a simple and green way for the application of natural products in the rubber industry.

Drying and adhesive properties of novel surface coatings derived from peanut skin extract and cashew nutshell liquid

PurposeThis study aims to synthesize pigment and resin from agro-wastes and use them in the formulation of eco-friendly surface coatings.Design/methodology/approachThe pigments and resin were synthesized through a chemical modification of agro-wastes. The pigments were characterized by infrared spectroscopy (FTIR) and were screened for their antimicrobial activities. The physicochemical characteristics of the cashew nutshell liquid (CNSL)-modified resin were evaluated. These precursors and other natural additives were used to formulate surface coatings, and their drying and adhesive properties were evaluated using international testing methods.FindingsIt was observed that the curing of the CNSL-modified resin depended on time and temperature. The pigments exhibited antimicrobial activity against E. coli and S. aureus and had high melting points, affirming their stability. The chemically modified precursors successfully yielded surface coatings with acceptable drying times and adhesion to the base substrate.Practical implicationsThe use of agro-wastes as the main components of the surface coatings implies waste valorization, a reduction in production costs and the creation of job opportunities for sustainable development. To increase the chemical, physical, corrosion resistance and antimicrobial qualities of paint compositions, chemically modified peanut skin extracts and CNSL can be used as pigments and resins, respectively. This could be a green approach to achieving the targets of Sustainable development goals 11 and 12.Originality/valueThe paper outlines a prospective approach to use unwanted waste (peanut skin, cashew nutshells) and other natural additives as industrial raw materials. These novel surface coating precursors are cost-effective, readily available, eco-friendly and could replace conventional precursors.

Effect of curing temperature on mechanical strength, hydrophobicity, chemical and thermal stability of Cardanol‐derived Resol‐polyurethane films/coatings

AbstractThe utilization of renewable resources has increased over the last few years in different fields due to environmental and economic concerns. Cashew nut shell liquid (CNSL) is cheaper, abundantly available, and an eco‐friendly agro‐waste product, which holds the potential to significantly replace petro‐based phenols. Present work focusses on the preparation of (i) Cardanol‐based polyols (resol) in different ratios [Cardanol: formaldehyde 1:1.2(Rol1), 1:1.6 (Rol2), and 1:2.0 (Rol3)], (ii) their polyurethanes, and (iii) freestanding, transparent, flexible and thin films/coatings obtained through “Green” route. The effect of curing temperature on the overall performance of films/coatings has also been investigated. The films/coatings obtained by baking at 80 ± 5°C (BK‐Rol1/2‐PU) exhibited improved physicomechanical performance compared with films/coatings obtained at room temperature (RT‐Rol1/2‐PU). BK‐Rol1/2‐PU and RT‐Rol1/2‐PU demonstrated excellent chemical stability. XRD revealed that both BK‐Rol2‐PU and RT‐Rol1/2‐PU films were amorphous and TGA confirmed that BK‐Rol2‐PU showed higher thermal stability compared with RT‐Rol2‐PU films. The contact angle measurements indicated a higher hydrophobic character of BK‐Rol1/2‐PU (96°) relative to RT‐Rol1/2‐PU (90°). These polyurethane films/coatings can be used for protective and decorative purposes. As BK‐Rol1/2‐PU films/coatings outperformed RT‐Rol1/2‐PU, the overall results confirmed that curing temperature had a remarkable effect on the performance characteristics of coatings/films.

Substitution of urea-formaldehyde by renewable phenolic compound for environmentally appropriate production of particleboards.

In recent years, research has been conducted in search of alternative adhesives that are less harmful to human health and the environment. Cardanol derived from cashew nut shell liquid (CNSL) has attracted considerable attention due to its chemical and specific characteristics (antioxidant activity, flame resistance, and hydrophobicity). In this sense, this study aimed to evaluate the quality of particleboards using cardanol instead of urea-formaldehyde (UF) adhesive. Different percentages of cardanol were used (0, 20, 40, 60 and 80%) in which its physicochemical properties were evaluated. The panels were produced with particles of Pinus oocarpa and nominal density of 0.75g/cm3, their physical and mechanical properties were evaluated, wood-adhesive interface evaluation with scanning electron microscopy (SEM), and the combustibility test. It is concluded that the maximum replacement of UF by cardanol is 5%, since, in this situation, the mentioned properties reach the established norms for the commercialization of the boards.

Collagen Cross-Linking Lignin Improves the Bonding Performance of Etch-and-Rinse Adhesives to Dentin.

To evaluate the biomodification ability of lignin used as pre-treatment in human dentin before the application of an etch-and-rinse adhesive. Experimental hydroethanolic solutions with different cross-linking agents were used: 6.5% proanthocyanidins (PAC, from grape-seed extract); 2% cardanol (CARD, from cashew-nut shell liquid); lignin (LIG, from eucalyptus) at 1, 2 or 4% concentrations. The negative control (NC) was ethanol 50 v%. Extracted molars were prepared, and dentin microtensile bond strength (μTBS) was evaluated after 24 h water storage or 10,000 thermocycling aging. Further specimens were processed for SEM nanoleakage, micropermeability confocal microscopy evaluation and in situ degree of conversion (DC) through micro-Raman spectroscopy. Demineralized dentin sticks were submitted to a three-point bending test to evaluate the elastic modulus (E) before and after 1 min biomodification using the tested solutions. Moreover, it was also evaluated the mass changes and hydroxyproline (HYP) release after 4-weeks of water storage. Vibrational collagen crosslinking identification was evaluated through micro-Raman spectroscopy. The results were analyzed by analysis of variance (ANOVA) and Tukey’s test (α = 0.05). A significant reduction in μTBS was observed in groups NC (p < 0.001) and CARD (p = 0.026). LIG-4% showed no significant reduction in μTBS after aging (p = 0.022). Nanoleakage micrographs showed hybrid layer protection with all agents, but reduced micropermeability was attained only with lignin. Polymerization was negatively affected in the presence of all tested cross-linking agents, except LIG-1%. Lignin and cardanol increased the dentin E values, but only lignin reduced the mass loss in dentin specimens. Effective collagen crosslinking (1117 cm−1 and 1235 cm−1) was detected for all agents. HYP release was significantly lower with LIG-1% than NC (p < 0.001). Lignin was able to perform collagen cross-linking and prevent the degradation of unprotected dentin collagen, thereby improving the bonding performance of the composite restorations performed in this study.

Evaluation of the antimicrobial activity of the extracts from cashew nutshell and castor oil plant / Avaliação da atividade antimicrobiana dos extratos da casca de caju e do óleo ricinoleico

Essential oils are natural extracts rich in bioactive compounds that possess antioxidant, antimicrobial, antiviral, and insecticidal properties. For this reason, they are investigated as a possible alternative to the use of antibiotics. Micellar and aqueous solutions from extracts derived from the cashew nut shell liquid and the ricinoleic acid extracted from the castor oil plant were screened to determine their minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against common bacteria, such as Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Methicillin-Resistant Staphylococcus aureus, and Staphylococcus epidermidis. The cashew nut shell oil showed activity against Gram-positive bacteria with the micellar suspension having the best results. Neither the micellar nor the aqueous solutions of the castor bean extract showed antimicrobial activity in this study.

Effect of Injection Parameters on the Performance of Compression Ignition Engine Powered with Jamun Seed and Cashew Nutshell B20 Biodiesel Blends

Renewable fuels are alternative resources that find use in the power generation, agricultural, and transportation sectors. The sustainable utility of these renewable fuels mostly addresses the socio-economic issues of a country and reduces its dependency on fossil fuels. In addition, being environmentally friendly allows them to handle global warming more effectively. Two B20 fuel blends were produced using methyl esters of cashew nutshell and jamun seed oils to test the performance of the common rail direct injection engine. To improve the engine performance, injection parameters such as nozzle geometry, injection time, and injector opening pressure are used. Improved brake thermal efficiency and lower emissions of smoke, hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) were achieved with the help of advancing the injection timing, raising the injector opening pressure, and increasing the number of injector nozzle holes. In addition to reducing the ignition delay, extending the combustion duration, and increasing the peak pressure, the revised injection settings also boosted the heat release rates. At the maximum load, compared to CHNOB B20, JAMNSOB B20 showed a significant rise in the brake thermal efficiency (BTE) by 4.94% and a considerable decrease in smoke emissions (0.8%) with an increase in NOx (1.45%), by varying the injection timing, injection pressure, and nozzle geometry of the common rail direct injection (CRDI) engine.

Tribological characterizations of bio-polymer based ecofriendly copper-free brake friction composites

PurposeThis study aims to discuss the impact of using bio-polymer (kraft lignin) in the formulation of passenger vehicle disc brake pads (as a substitute for cashew nutshell liquid [CNSL]-based friction dust) and investigate the characteristics of the pads.Design/methodology/approachWithin the scope of this investigation, three different brake pads were generated by altering the biopolymer-lignin content in conjunction with the friction dust from CNSL without modifying the other components. The brake pads were created in accordance with industry-standard practices. Industrial standards were used to evaluate the newly created brake pad’s thermal, physical and mechanical qualities. The tribological properties of the materials were determined using a full-scale inertia brake dynamometer. The scanning electron microscope examined the worn surfaces in conjunction with elemental mapping.FindingsThe test findings suggest that the brake pads filled with biopolymer-lignin and CNSL-based friction dust (as a partial replacement 50%) exhibited excellent thermal, physical, mechanical characteristics, as well as steady friction and low wear rate.Originality/valueA bio-polymer (kraft lignin) in friction composites has the potential to produce eco-friendly brake pads and improve the tribological performance of its copper free-composition, which might be used to replace CNSL-based friction dust in friction composites by addressing the issues raised in this work.

Capacitance Value Analysis of Composites of Activated Cashew Shells Charcoal and Iron Sand

&lt;p class="AbstractText"&gt;&lt;span lang="EN-AU"&gt;This study aims to determine the use of iron sand extract and cashew nut shell activated charcoal in the capacitor manufacturing process and determine the effect of grain size on the capacitor capacitance with electrodes from a composite of iron sand extraction and activated charcoal from cashew nutshells. The sample preparation of cashew nutshell activated charcoal was carried out by carbonation and activation methods at a temperature of 700 &lt;sup&gt;0&lt;/sup&gt;C and continued by extracting iron sand. The results of the iron sand extract were then crushed using a mortar, followed by varying the mass fraction of iron sand starting at 40%, 60%, and 80% for each particle size (60 mesh, 100 mesh, and 200 mesh). Then composite the iron sand extract and activated charcoal mixed for 4 hours, and added 0.7 mL of LiNO&lt;sub&gt;3&lt;/sub&gt; 1M solution. The analysis showed that the highest specific capacitance was found in the 200 mesh grain size, namely 0.0695 F/g.&lt;/span&gt;&lt;/p&gt;

Bio-based one-component epoxy resin: Novel high-performance anticorrosive coating from agro-industrial byproduct

In this present work, an epoxy resin produced from an agroindustrial byproduct, cashew nutshell liquid (CNSL), was used for manufacturing a one-component anticorrosive epoxy coating. CNSL-based epoxy resin (e-CNSL) was synthesized using a solvent-free methodology with performic acid generated in situ. The chemical structure of resin was evaluated by FTIR and 1H NMR. The curing parameters of the epoxy-phenol system with 1-methylimidazole (1-MIM) as an accelerator were investigated by differential scanning calorimetry (DSC). The use of only 5% by weight of 1-MIM was efficient to catalyze the reaction, obtaining the lowest cure temperature (150 °C). The coating showed high crosslinking and good thermal-mechanical performance, where the initial decomposition temperature was 200 °C and glass transition temperature was 30 °C. The anti-corrosive performance of e-CNSL/MIM5 exposed to salt spray and 3.5% w/v NaCl solution was monitored by electrochemical impedance spectroscopy, adhesion, and visual evaluation during the exposure period. Humidity test with visual evaluation was also performed. The coating presented high impedance module at 108 Ω.cm2 and high adhesive property, suffering low delamination during the tests. Thus, the one-component bio-based coating developed is promising to be applied for corrosion protection purposes.
