Bacterial cellulose-natural fiber composites produced by fibers extracted from banana peel waste

In recent times, there is a growing demand for low-cost raw materials, renewable resources, and eco-friendly end products. Natural fibers are considered as strong candidates to be used as a potential reinforcement for composite manufacturing. In the current study, natural fibers extracted from banana peel were coated with bacterial cellulose through a green biosynthesis approach as well as by a simple slurry dipping method. Thus, natural fibers from banana peel waste were used the first time, to produce bacterial cellulose-natural fiber composites. SEM analysis revealed good interaction between the hybrid fibers and the epoxy matrix. Thermal gravimetric analysis results revealed that the degradation temperature increases because of the addition of bacterial cellulose on fiber surface, which improves the thermal stability. The maximum thermal decomposition temperature (405°C) was noticed for nanocomposites reinforced by banana fibers with bacterial cellulose deposited on their surface. Whereas the lowest weight loss was also found for the same sample group. The highest tensile strength (57.95 MPa) was found for SBC-BP/epoxy, followed by DBC-BP/epoxy (54.73 MPa) and NBP/epoxy (45.32 MPa) composites, respectively. Composites reinforced by both types of hybrid banana fibers shown comparatively higher tensile performance as compared with the neat banana peel fiber-epoxy composites, which can be attributed to the high strength and stiffness associated with the bacterial cellulose. Overall, this study suggests a successful and green route for the fabrication of natural fiber-reinforced composites with improved properties such as tensile strength and thermal stability.

Effect of coated and encapsulated polyacrylate/nano-SiO2 composite emulsions on the finishing performances of leather via miniemulsion polymerization

In this study, the polyacrylate/nano-SiO2 (PA/SiO2) composite emulsion with ideal encapsulated and coated morphologies were prepared by miniemulsion polymerization. They, respectively, are encapsulated PA/SiO2-S composite emulsion, coated PA/SiO2-Q and PA/SiO2-W composite emulsion. The morphology of the composite emulsions were characterized by transmission electron microscope, and the results showed that the nano-SiO2 were encapsulated inside or coated around the latex particles. We investigated microstructure and properties of the composite emulsions after film formation which effect by nano-SiO2 existence forms by scanning electron microscope, thermogravimetric analysis, tensile strength, elongation at break and water absorption test. The PA/SiO2-W composite film had the best tensile strength of 6.3 MPa and a maximum thermal decomposition temperature of 415.2 °C. Furthermore, the PA/SiO2 composite emulsions were applied to leather finishing. The results demonstrated that the PA/SiO2-W composite emulsion increased the breathability and water vapor permeability of leather simple to 210.8% and 69.8%, respectively, which shows the emulsion has excellent comprehensive performance and potential application as the leather finishing agent.

Preparation and Mechanical Properties of Short Carbon Fiber Networks Reinforced Anionic Polymerized Nylon 6 Composites

Short carbon fiber three-dimensional network reinforcement (SCFNR) was prepared by bonding two different lengths of short carbon fibers (SCF) with phenolic resin powder (PF), and then carbonized at 800 °C. Two kinds of SCFNR/anionic polyamide 6 (APA6) composites were fabricated via vacuum assisted impregnation process (VAI). The microstructures and mechanical properties of the composites were characterized by scanning electron microscopy and universal testing machine. The thermal stability of the composites was evaluated by thermogravimetric. The results show that the carbonized phenolic resin can effectively bond SCF to form a rigid three-dimensional network reinforcement, both types of SCFNR can significantly improve the mechanical properties of the composites. The maximum thermal decomposition temperature of SCFNR/APA6 composite prepared with the carbon fiber length of 1 mm is 150 °C higher than that of APA6

Processing and characterizations of rotary linear needleless electrospun polyvinyl alcohol(PVA)/Chitosan(CS)/Graphene(Gr) nanofibrous membranes

The traditional electrospinning needles are easily blocked and the processing is not suitable for mass production. In order to address the problems, this study uses a rotary linear electrode for electrospinning for the production of polyvinyl alcohol (PVA)/chitosan(CS)/graphene(Gr) nanofibrous membranes. The membranes are observed for micro-structure and tested for thermal stability, surface resistivity, and hydrophilicity, thereby examining the influence of the content of chitosan. The test results show that the presence of chitosan improves the hydrophilcity as well as affects the morphology of PVA/CS/Gr nanofibrous membranes where the nanofiber diameter is smaller. Moreover, FTIR results suggest that chitosan and PVA interact to generate hydrogen bonds that stabilize the thermal properties of nanofibrous membranes. In particular, the maximum thermal decomposition temperature of PVA/CS/Gr nanofibrous membranes composed of PVA/CS ratio being 9:1 is 297.7 ℃. Finally, using chitosan also increases the electrical conductivity and decreases the surface resistivity. This fabricated technique provides the possibility of mass-production of PVA/CS/Gr nanofibrous membranes in the future.

Improvement in thermal, mechanical, and barrier properties of biocomposite of poly (3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate)/modified nano‐SiO2

AbstractA biocomposite of poly (3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate) (PHBH)/nano‐SiO2 modified with silane coupling agent KH570 (KH570‐SiO2/PHBH) were prepared by solution‐casting method. SiO2 modified with KH570 exhibited improved uniform dispersion than that of pure nano‐SiO2, and maximum thermal decomposition temperature range and crystallinity (Xc) of KH570‐SiO2/PHBH are 8.6°C and 119.7% higher than that of neat PHBH. Compared to the neat PHBH, a 75.4% and 70.8% improvement in Young's modulus and tensile strength were obtained. The water‐vapor transmission and oxygen permeance of KH570‐SiO2/PHBH decreased by 46.2% and 618.6%, respectively. The oxygen barrier property is equivalent to that of polyvinylidene chloride. Simultaneous enhancements on the thermal stability, mechanical, crystallizing, and barrier properties were mainly caused by uniform dispersion of modified nano‐SiO2 and solid interfacial bonding between filler and matrix.

Synthesis of a novel biocomposite of poly (3-hydroxybutyrate-co-3-hydroxyhexanoate) reinforced with acetylated cellulose nanocrystals

A novel biocomposite of poly (3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH)/acetylated cellulose nanocrystals (ACN/PHBH) was prepared by solution-casting after surface modification of cellulose nanocrystals (CNCs). Acetylated cellulose nanocrystals (ACNs) exhibited improved dispersion in PHBH compared with non-acetylated CNCs, and maximum thermal decomposition temperature of ACN/PHBH was 13 °C higher than that of neat PHBH. Compared to the neat PHBH and CNC/PHBH, 57.6% and 24.5% improvements in tensile strength, and 52.4% and 30.6% improvements in Young’s modulus were obtained for the bionanocomposites. The water-vapour and the oxygen barrier properties of ACN/PHBH improved by 76.1% and 30.4% compared with CNC/PHBH samples. Simultaneous enhancements on the thermal stability, mechanical and barrier properties were mainly caused by uniform dispersion of ACNs and solid interfacial bonding between filler and matrix. This performance of the bionanocomposite will broaden the utilization of CNCs as renewable bioresources and the practical application of PHBH-based plastics as replacements for traditional petrochemical materials.

Designing Coconut Oil Encapsulated Poly(stearyl methacrylate‐co‐hydroxylethyl metacrylate) Based Microcapsule for Phase Change Materials

AbstractPhase change material (PCM) is an effective energy storage application, which has a relatively low cost. In this study, bio‐based PCMs were prepared by using two techniques: encapsulation and UV‐curing. Encapsulated–PCM was synthesized by suspension polymerization with stearyl methacrylate (SMA) and hydroxyethyl methacrylate (HEMA). In encapsulation process, the microcapsules were prepared from poly(stearyl methacrylate‐co‐hydroxyethyl methacrylate) shell and coconut oil (CO) core. UV‐cured form stable PCM was also prepared by radical addition polymerization of stearyl methacrylate, hydroxyethyl methacrylate and coconut oil. In UV‐curing process as in the second process, coconut oil was trapped within the polymeric network without covalent bonding. Thermal storage feature of encapsulated‐PCM and UV‐cured form stable PCM was investigated. The melting enthalpy of encapsulated‐PCM is 119 J/g, which is higher than both the melting enthalpy of pure coconut oil (106 J/g) and UV‐cured form stable PCM (47 J/g). Moreover, thermal degradation results of PCMs show that the maximum thermal decomposition temperature of encapsulated‐PCM increased compared with UV‐cured from stable PCM.

Synthesis and characterization of a novel tri-functional bio-based methacrylate prepolymer from castor oil and its application in UV-curable coatings

A novel tri-functional castor oil-based methacrylate prepolymer (MCOG) was developed by mercapto castor oil (MCO) and glycidyl methacrylate (GMA) in this study through a two-step method. Primarily, the mercapto castor oil (MCO) was prepared through thiol-ene reaction of castor oil and mercaptoacetic acid, and subsequently an esterification reaction based on above product and glycidyl methacrylate (GMA) was conducted. FT-IR and 1H NMR spectra collectively revealed that MCOG was successfully synthesized. As a dominant component, MCOG was formulated with other additives including a reactive diluent pentaerythritol tri-acrylate (PETA), a photo-initiator (TPO) and another self-made polyurethane acylate prepolymers (B-215) and cured under UV irradiations. UV-curing kinetics of the MCOG/PETA/B-215 film was detailly investigated by tracing the ATR-IR spectroscopy and gel content and it demonstrated that the cured films had more than 95% CC double bond conversion. Moreover, dynamic mechanical property, thermal stability and mechanical property of the cured films were respectively determined by dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA) and tensile measurement. DMA testified that with the increasing of B-215 content, storage modulus, cross-linking density of the cured films dropped, whereas the corresponding glass transition temperatures (Tg) increased. TGA showed that the maximum thermal decomposition temperatures were all above 460 °C. Tensile tests indicated that the better tensile strength was obtained with the content of 20% of the B-215 in the cured film. Additionally, transparency and flexibility of the cured films were respectively analyzed by digital image and scanning electron microscopy (SEM). Besides, these cured films displayed high pencil hardness (5H–6H) and excellent resistance to acidic and alkali solutions.

Synthesis and characterization of novel renewable tung oil-based UV-curable active monomers and bio-based copolymers

With the rapid development of industry and the growing shortage of fossil energy, tung oil has attracted much attention of researchers because of its environment-friendly and renewable advantages. In this work, we successfully synthesized two kinds of tung-oil-derived renewable UV-curable active monomers, tung-acid-maleic tri-acrylate (TOAH) and tung-maleic tetra-acrylate (TMPG). 1H NMR and FT-IR results collectively revealed that the targeted active-monomers were successfully prepared. UV-curing kinetics of the films was studied by Photo-DSC, thermal properties of their cured films were investigated by dynamic mechanical analysis, thermogravimetric analysis and general performance of UV-curing films including acidic, alkaline resistance and boiling-water resistance were also investigated. Tensile properties of the cured films were also tested. Dynamic mechanical analysis demonstrated that the storage modulus and glass transition temperatures of the cured films increased while increasing the content of TMPG monomer. The crosslinking density of the cured copolymers also increased with the increasing content of TMPG monomer. TGA showed that the maximum thermal decomposition temperatures (Tmax) of the cured copolymers were all above 420 °C. Tensile tests indicated that the tensile properties were better in the cured systems when the mixed films consisted of 50TOAH/50TMPG and 30% HDDA reactive diluent. Finally, all the results demonstrated that comparable balanced properties could be obtained by mixing these two bio-based monomers together.

Mechanical, thermal, and barrier properties of PHBH/cellulose biocomposite films prepared by the solution casting method

A biocomposite film from bacterial polyester, poly(3- hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH), and natural cellulose was developed by the solution casting method. The structure, the mechanical, thermal, and barrier properties (oxygen and water vapor), and the biodegradation of the PHBH/cellulose biocomposite films were studied. With an increase in cellulose content, the tensile strength of biocomposite films increased from 28.5 MPa to 45.9 MPa, an improvement of 351% compared with neat PHBH. The PHBH/cellulose biocomposite films exhibited improved thermal stability, with the maximum thermal decomposition temperature increased from 264 °C to 330 °C. More importantly, PHBH/cellulose biocomposite films possessed better barrier properties against oxygen, up to approximately 10 times more than neat PHBH. With cellulose content increased from 50 wt% to 90 wt%, the mass loss of composite films increased gradually and then decreased. This high performance biocomposite has potential to expand the use of cellulose from renewable bioresources and the practical application of PHBH-based biodegradable plastics instead of traditional petrochemical materials in the packaging field.

VOC and PAH characterization of petroleum coke at maximum thermal decomposition temperature

ABSTRACTIn steel industry, hard coal is proceeded in coke ovens to produce metallurgical coke. In this process, some additives such as petroleum coke (petcoke) are used for optimizing operational cost. For the determination of addition ratio of petcoke, it is important not to disrupt coke quality, especially with respect to coke reactivity index and coke strength after reaction, while another important point is emission quality. In this study, petcoke gas (PCG) emitted from the thermal decomposition of petcoke at the maximum thermal decomposition temperature is characterized for volatile organic compounds (VOCs) and polyaromatic hydrocarbons (PAHs) and the results are assessed in comparison to the coke oven gas (COG). First, the petcoke sample is heated for gasification by using thermal gravimetric analyzer-DTA device. The gas in the temperature range of 490–510°C, where the highest gasification acceleration occurs, is taken from the funnel and transferred to GC-MS device by using a headspace gas sampler unit. The total VOC concentration in PCG and COG is found to be 121.76 ppm and 5,774.76 ppm, respectively, while the total PAH concentrations are 0.625 and 0.495 ppm, respectively. The results show that using petcoke in coal blend seems to be a more environment-friendly process with respect to a significant decrease in VOC emissions.

Efficient polymeric phosphorus flame retardant: flame retardancy, thermal property, and physical property on polylactide

A novel polymeric flame retardant, PBPP2, for polylactide (PLA) was synthesized via a two-step polymerization process. The flame retardancy of neat PLA and flame-retarded PLA films prepared via solution casting method with different PBPP2 ratios was then investigated. When only the 3 wt% PBPP2 was added to PLA, the limiting oxygen index was increased from 23 to 30%. Additionally, the required V-0 rating was achieved compared to neat PLA. It was also found that PBPP2 increases the maximum thermal decomposition temperature of PLA, indicating that 3 wt% of PBPP2 is sufficient to improve flame retardancy and thermal stability on PLA, simultaneously. From both the decrease in Tm and the increase in elongation for PLA with the 3 wt% addition of PBPP2, PBPP2 could be considered to also function as a plasticizer on PLA.

Preparation and Characteristics of Biocomposites Based on Steam Exploded Sisal Fiber Modified with Amphipathic Epoxidized Soybean Oil Resin.

Sisal fiber was pretreated by continuous screw extrusion steam explosion to prepare steam exploded sisal fiber (SESF) preforms. An amphipathic bio-based thermosetting resin with poor mechanical properties was cured by epoxidized soybean oil (ESO) and citric acid (CA). The obtained resin was used to modify SESF preforms and prepare eco-friendly biocomposites. The molar ratios (R) of carboxylic groups to epoxy groups and resin contents in biocomposites were adjusted. The biocomposites were characterized by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), Fourier-transfer infrared spectroscopy (FT-IR), tensile testing, scanning electron microscopy (SEM), water absorption and water contact angle measurements. The maximum thermal decomposition temperature of the biocomposites was 373.1 °C. The curing efficiency of the resin in the biocomposites improved with the increase of resin content, and reached a maximum at R = 1.2. The tensile strength of the biocomposites reached a maximum of 30.4 MPa at R = 1.2 and 40% resin content. SEM images showed excellent interfacial bonding and fracture mechanisms within the biocomposites. The biocomposites exhibited satisfactory water resistance. ESO resin cured with polybasic carboxylic acid is therefore a good bio-based modifier for lignocellulose, that prepare biocomposites with good mechanical properties, hydrophobicity, and thermostability, and which has a potential application in packaging.

Characterization of polyurethane foams prepared from liquefied sawdust by crude glycerol and polyethylene glycol

The aim of this study was to investigate polyurethane foams (PUF) properties obtained from crude glycerol (CG) and polyethylene glycol (PEG) based liquefaction of sawdust. The four types of foam were prepared by producing polyols from different weight loadings of PEG to CG as the liquefaction solvent. The produced polyurethane foams showed densities from 0.042 to 0.08 g/cm3 and compressive strengths from 200 to 311 kPa. The foams obtained from CG/PEG based liquefaction, had more uniform and regular cell structure than foams derived from liquefaction by CG. Also with the increasing percentage of PEG to CG in liquefaction, closed cell content of the synthesized foams increased and the size of cells decreased. The thermal conductivity of the produced foams was between 0.031 and 0.040 W/m K. Foams produced from liquefaction by binary solvent had lower thermal conductivity. However all foams showed approximately similar thermal degradation curves; maximum thermal decomposition temperature was seen for the foam produced from higher weight ratio of PEG to CG in liquefaction. PU foams produced from PEG/CG based liquefaction process had improved properties over from foams derived from sawdust liquefaction by CG.

Enhancing Fracture Toughness and Stress Energy Release Rate of Vinyl Ester Matrix Using Dual Reinforcement of CNT and GNP

ABSTRACTIn this paper, we report a method of increasing fracture toughness (KIC) and strain energy release rate (GIC) of vinyl ester matrix by adopting a dual reinforcement strategy. Reinforcements were carbon nanotubes (CNT) and graphene nanoplatelets (GNP). Both categories of nanoparticles were functionalized with COOH. The idea was to enhance crack bridging and interface sliding with CNT inclusions, given their high aspect ratio. In addition, promote crack-tip blunting and cross-linking density with GNP inclusions, due to their platelet structures. Both KIC and GIC were measured using ASTM D5045-14. An exhaustive experimental study revealed an optimum loading of both nanoparticles to be 0.25 wt% CNT and 0.5 wt% GNP, based on the highest combination of KIC and GIC values. We observed that stress intensity factor, KIC, of neat vinyl ester increased by 43% from 1.14 to 1.62 MPa*(m½). Meanwhile, the improvement in GIC was even greater with an increase of 65%, i.e., from 370 to 610 J/(m2). Differential scanning calorimetry (DSC) studies showed a discernible shift in glass transition temperature (Tg) from 123 to 128°C. The slight temperature increase was similar in thermogravimetric analysis (TGA). We observed the maximum thermal decomposition temperature (Tp) increase from 410 to 414°C, as was evident in the derivative TGA (DTG) curves.

Physicochemical and Spectroscopic Characterization of Biofield TreatedButylated Hydroxytoluene

The antioxidants play an important role in the preservation of foods and the management of oxidative stress related diseases by acting on reactive oxygen species and free radicals. However, their use in high temperature processed food and pharmaceuticals are limited due to its low thermal stability. The objective of the study was to use the biofield energy treatment on butylated hydroxytoluene (BHT) i.e. antioxidant and analyse its impact on the physical, thermal, and spectral properties of BHT. For the study, the sample was divided into two groups and termed as control and treated. The treated group was subjected to biofield energy treatment. The characterization of treated sample was done using X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) and UV-visible (UV-Vis) spectroscopy. The XRD results showed the alteration in lattice parameters, unit cell volume, and molecular weight along with 14.8% reduction in the crystallite size of treated sample as compared to the control. The DSC analysis showed an increase in the latent heat of fusion from 75.94 J/g (control) to 96.23 J/g in the treated BHT sample. The TGA analysis showed an increase in onset temperature of decomposition (130°C→136°C) and maximum thermal decomposition temperature (152.39°C→158.42°C) in the treated sample as compared to the control. Besides, the FT-IR analysis reported the shifting of aromatic C-H stretching peak towards higher frequency (3068→3150 cm-1) and C=C stretching towards lower frequency (1603→1575 cm-1) as compared to the control sample. Moreover, the UV spectrum also revealed the shifting of the peak at λmax 247 nm (control) to 223 nm in the treated sample. The overall results showed the impact of biofield energy treatment on physical, thermal and spectral properties of BHT sample.

Separation and structural characteristics of lignin in the prehydrolysis liquor of Whangee dissolving pulp

Separation and structural characterization of lignin are essential for value-added utilization of hemicelluloses and lignin in the prehydrolysis liquor (PHL) of a kraft-based Whangee (a genus of bamboo) dissolving pulp production. In this work, lignin in the PHL was separated by acidification treatment (AT) and rotary vacuum evaporation treatment (RVET), and the separated crude lignin was then compared and characterized. The crude lignin separated by RVET could be justified as p-hydroxyphenyl (H) -syringyl (S) -guaiacyl (G) lignin, and a conjugated carbonyl was also found in it. The crude lignin separated by AT was mainly composed of S lignin that had β-1, β-5, β-O-4, and β-β bonds. Thermogravimetric analysis (TGA) showed that the maximum thermal decomposition temperatures and the final carbon residues of crude lignin separated by RVET and AT were 520 °C, 5.26%, and 470 °C, 27.92%, respectively. Moreover, of the five kinds of sugar (arabinose, galactose, glucose, xylose and mannose) in the PHL, only galactose and glucose were decreased after AT, while all five kinds were decreased after RVET.

Improved thermal stability of cellulose nanofibrils using low-concentration alkaline pretreatment

The thermal stability of cellulose nanofibrils (CNFs) can be improved by converting cellulose crystalline structure to cellulose II using an alkaline treatment method. The conventional method requires around 20wt.% NaOH solutions and causes the cellulose interdigitation and aggregation, making CNFs production difficult. The objective of this study is to develop a new pretreatment method using a low-concentration alkaline solution to produce well-dispersed CNFs with improved thermal stability. CNFs with 90nm diameter were successfully prepared by treating cellulose powder with 2wt.% NaOH solution below 0°C, followed by homogenization through a French pressure cell press. The CNFs had relatively high thermal stability with the mean onset and maximum thermal decomposition temperature of 305°C and 343°C, respectively, compared with the CNFs prepared without the NaOH pretreatment (283°C and 310°C). The increased thermal stability can create new opportunities for the development of CNF-based bio-composites and electronics.

Coaxial Electrospinning and Characterization of Core-Shell Structured Cellulose Nanocrystal Reinforced PMMA/PAN Composite Fibers.

A modified coaxial electrospinning process was used to prepare composite nanofibrous mats from a poly(methyl methacrylate) (PMMA) solution with the addition of different cellulose nanocrystals (CNCs) as the sheath fluid and polyacrylonitrile (PAN) solution as the core fluid. This study investigated the conductivity of the as-spun solutions that increased significantly with increasing CNCs addition, which favors forming uniform fibers. This study discussed the effect of different CNCs addition on the morphology, thermal behavior, and the multilevel structure of the coaxial electrospun PMMA + CNCs/PAN composite nanofibers. A morphology analysis of the nanofibrous mats clearly demonstrated that the CNCs facilitated the production of the composite nanofibers with a core-shell structure. The diameter of the composite nanofibers decreased and the uniformity increased with increasing CNCs concentrations in the shell fluid. The composite nanofibrous mats had the maximum thermal decomposition temperature that was substantially higher than electrospun pure PMMA, PAN, as well as the core-shell PMMA/PAN nanocomposite. The BET (Brunauer, Emmett and Teller) formula results showed that the specific surface area of the CNCs reinforced core-shell composite significantly increased with increasing CNCs content. The specific surface area of the composite with 20% CNCs loading rose to 9.62 m2/g from 3.76 m2/g for the control. A dense porous structure was formed on the surface of the electrospun core-shell fibers.

Assessment of Physicochemical and Thermal Properties of Energy of Consciousness Healing Treated Ferrous Sulphate Using PXRD, PSD, DSC, and TGA/DTG Analysis

Ferrous sulphate is an inorganic salt of iron used to treat iron deficiency anaemia and maintain the overall health in our body. The current study was designed to evaluate the impact of The Trivedi Effect®-Energy of Consciousness Healing Treatment on the physicochemical and thermal properties of ferrous sulphate using PXRD, PSA, DSC, and TGA/DTG analysis. Ferrous sulphate test item was divided into two parts, one part was considered as control (without Biofield Energy Treatment), whereas the second part received The Trivedi Effect®-Biofield Energy Treatment remotely by the renowned Biofield Energy Healer, Alice Branton. The PXRD data revealed that the relative intensities and crystallite size of the characteristic diffraction peaks in the treated sample were significantly altered from -26.74% to 421.23% and from -24.93% to 42.91%, respectively compared with the control sample. The average crystallite size of the treated sample was significantly increased by 6.39% compared to the control sample. The particle size values at d10, d50, d90 and D(4, 3) values were significantly increased by 30.43%, 35.94%, 19.49%, and 26.26%, respectively and the surface area was significantly decreased by 53.26% compared with the control sample. The melting temperature of the treated sample in the 1st and 3rd peaks was increased by 1.61% and 1.04% respectively, whereas decreased by 5.71% and 1.04% in the 2nd and 4th peaks, respectively compared with the control sample. Consequently, the total latent heat of fusion to transition from FeSO4•7H2O to FeSO4 was decreased by 0.44% in the treated sample compared with the control sample. The TGA thermograms of both the samples exhibited four steps of thermal degradation. The total weight loss in the treated sample was increased by 0.62% compared with the control sample. The maximum thermal decomposition temperature (Tmax) of treated sample was increased by 5.81% and 0.26% in the 1st and 4th peak respectively, but the Tmax of 2nd and 3rd peaks were decreased by 2.58% and 2.38%, respectively compared to the control sample. Overall, DSC and TGA/DTG of the treated sample showed that the thermal stability was changed compared with the control sample. The Trivedi Effect®-Consciousness Energy Healing Treatment might lead to the production of a polymorphic form of ferrous sulphate, which would have better powder flowability and appearance with altered thermal stability compared to the control sample. Alice’s Biofield Energy Treated ferrous sulphate would be useful to design better nutraceutical/pharmaceutical formulations, which could provide better therapeutic response against iron deficiency anaemia.
