Nutraceutical industrial fenugreek seed spent (NIFGS), a relatively low-cost material abundantly available with nearly negligible toxicity for the bioremediation of malachite green (MG) dye from aqueous media, is reported. Studies on the various parameters affecting the adsorption capacity of NIFGS were carried out to evaluate the kinetics and the equilibrium thermodynamics. All the experiments were designed at about pH 7. The adsorption isotherm model proposed by Langmuir fits better than the Freundlich isotherm model. Kinetic study data confirms the viability of pseudo-second-order model. Calculated thermodynamic factors suggest that the adsorption phenomenon is endothermic, almost instantaneous, and physical in nature.

The diabetes is a disease that can become a serious disorder for a lifetime. It kills more than a million people every year. This disease can affect anyone. Diabetes occurs when the body is unable to process all the sugar (glucose) in the bloodstream; its complications can move to heart issues, caress, vision loss, and kidney stoppage and leg amputation problems. Many people with diabetes inject their body daily and feel that their work is done. Diabetes is an incurable disease because of poor health. The diabetes be able to be divided keen on2 types. The type-1 diabetes is hereditary. It is not easy to cure. People with type 2 diabetes can greatly reduce their risk of developing diabetes by following a proper, proper lifestyle. In addition it helps reduce the risk of diabetes. The proposed model of managing diabetics explains this disease as a specific lifestyle. The existence of an effective system for the treatment of diabetes, according to the tasks currently set out, provides for the achievement of goals. The proposed edge based machine learning approach was achieved 85% of results compared with the Blood glucose level prediction, Adaptive multivariable closed-loop control, neural model of blood glucose level and Detecting Undiagnosed Diabetes.

In this study, use of low-cost nutraceutical industrial coriander seed spent (NICSS) for removing Acid Blue 113 (AB113) from aqueous solution has been explored. Biosorption studies were done under varying conditions of initial pH, initial dye concentration, adsorbent dosage, particle size of the adsorbent and temperature to assess the adsorption capacity, kinetics and equilibrium thermodynamics. Optimal adsorption took place at acidic pH. A two-level fractional factorial experimental design (FFED) and analysis of variance (ANOVA) showed that a maximum adsorption value of 90.00 mg/mL was possible. The influence of each parameter and combination of parameters on the final adsorption capacity of the system was studied. The dye uptake followed a pseudo-second order kinetic paradigm and was best described by the Langmuir isotherm. Intra-particle diffusion showed that the adsorption mechanism was more governed by external mass transfer. AB113 adsorption on NICSS was endothermic and almost spontaneous. The NICSS has a highly fibrous matrix with hierarchical porous structure as evidenced by SEM images. Analysis of the spent showed that it possesses cellulosic and ligno-cellulosic materials having both hydrophilic and hydrophobic properties. The results proved that NICSS efficiently removes AB113 from water and textile industrial effluents.

First-ever study on the adsorption of Acid Violet 49 (AV49) dye, onto nutraceutical industrial chillies stalk waste (NICSW) is reported. A two-level fractional factorial experiment design and analysis of variance (ANOVA) were adopted to study how initial concentration of the dye, adsorbent dosage, duration of adsorption process, speed of agitation, pH of the reaction mixture and temperature affect the adsorption process. The adsorption capacity of NICSW at equilibrium was analyzed using Langmuir, Freundlich, Jovanovic, Temkin, Dubinin–Radushkevich and Harkins–Jura isotherms. The pseudo-first-order and pseudo-second-order models were considered for kinetic studies. Maximum adsorption capacity of 45.40 mg/g was obtained by Langmuir isotherm as against the experimental value of 29.00 mg/g, with correlation coefficient of 0.979 at near neutral pH. NICSW was characterized by Fourier transform infrared spectroscopy, Brunauer–Emmett–Teller, scanning electron microscope and energy dispersive X-ray spectroscopy. Elemental (C, H, N, S) analyses of the adsorbent were conducted. Along with thermodynamic parameter evaluation such as Gibb’s free energy, enthalpy and entropy and results of the surface characterization showed that the dye adsorption onto the biosorbent has taken place such as a physical process. These results proved that NICSW is a fast and effective adsorbent to remove AV49 from water and textile industrial effluent.

Cellulose is a very widely available biomass found in nature. Cellulose can be isolated from regular filaments; its dynamic and structural association enables various types of nanostructured celluloses called nanocrystalline cellulose or microstructure cellulose. More recently, literature survey reveals that cellulose nanoparticles have been separated and utilised for a few applications in various fields. Thus, there is a growing interest among the scientific research community to understand nanocrystalline cellulose and tap it for its usage in diverse scientific fields. The vast majority of the examinations in the course of the most recent couple of years have demonstrated that nanocrystalline cellulose can be utilised as filler materials to improve the mechanical and barrier properties of biocomposites. Their importance of nanocrystalline to enhance the mechanical properties is being investigated; with extensive research being focussed to discover inventive answers for effective and manageable frame works. This paper plans to give an unmistakable outline of nanocrystalline cellulose of 44 references by depicting their readiness, portrayal, behaviour, importance and applications.

Everything around us is made up of atoms and molecules. The properties of quantum atoms are sought to understand the behavior of a particular object. But with the advent of research, it was discovered that there is a quantity smaller than the molecular size. The nanoscale measures a fraction of a billionth of a meter. The atom of an object measures 0.1 nm. Since atoms are the building blocks of matter, at the nanoscale one can combine these atoms to create new materials. The proposed model displays the properties of these nano-scale elements in modern medical applications. The nano-scale research of matter is fascinating because it is the basic phase in which atoms are held together. Therefore, by manipulating material at this level, one can create many different types of objects. This proposed model calculates the operation requirements and expects the results. Based on the operational requirements, the proposed model provides the suggestions. This will be helpful for the medical researchers to identify the proper medical treatments based on the microbiological requirements.

The present study reports about the use of fenugreek seed spent as a new and efficient biosorbent for the removal of acid blue 113 dye from aqueous media and textile industrial effluent. The spent is a low-cost by-product of nutraceutical industry. The effects of various process parameters of adsorption, such as pH, initial dye concentration, adsorbent dose, adsorbent particle size, contact time and temperature onto nutraceutical industrial fenugreek seed spent (NIFGS) have been studied. Four numbers of two-parameter and six numbers of three-parameter isotherm models were used in the analysis of adsorption equilibrium data. Kinetic studies data conformed to pseudo-second-order model. Molecular diffusion studies were carried out using Weber–Morris, Dumwald–Wagner and film diffusion models. Change in enthalpy (ΔH°), entropy change (ΔS°) and Gibbs free energy change (ΔG°) of adsorption system indicated that the process is physisorption. Scanning electron microscopy, Fourier transform infrared spectroscopy and point of zero charge were used in characterizing the adsorbent. Fractional factorial experimental design and analysis of variance along with statistically developed model for adsorption helped to predict for a maximum adsorption of 661.5 mg g−1using NIFGS. Application of NIFGS to textile industrial effluent and scaling up of the experimental process by three orders gave encouraging results.
