Efficient green combustion production of pure nickel oxide (NiO) and silver-doped NiO nanoparticles using Aloe Vera gel extract: Its supercapacitors applications

This study employs the synthesis of pure NiO and Ag-doped NiO with varying concentrations (1, 3, 5, 7 and 9 mol%) of Ag2O nanoparticles by solution combustion method. The Structural and morphology of nanomaterials were elucidated by analytical spectroscopic methods. XRD revealed alterations in physical properties, such as crystallite size and lattice parameters, of NiO nanoparticles due to the presence of Ag2O. UV-Vis spectroscopy demonstrated a reduction in the bandgap from 3.41 eV (pure NiO) to 3.21 eV for 1, 3, 5, 7 and 9 mol% Ag2O-doped NiONPs. To assess their viability as active electrode materials in supercapacitors, the synthesized samples were subjected to analysis in a 0.1 M HCl electrolyte. Electrochemical studies done through various tests, including Electrochemical-Impedance, Cyclic-Voltammetry and Galvanic Charge-Discharge. Remarkably, the 5 mol% Ag2O-doped NiO in a 3-electrode system exhibited a notable capacitance value of 248 Fg−1 at a scan rate of 5 Ag−1. Additionally, it demonstrated robust cycling stability, maintaining over 90% of the original capacitance after 2000 cycles in GCD studies. The potential chemical interaction between nanoscale Ag2O and NiO could be responsible for the enhanced capacitance. These findings offer valuable insights for researchers exploring the development of novel electrode materials for energy-storage devices.

Effect of edible coating containing Aloe vera extracts on the oxidative stability and quality parameters of cooked ground chicken meat

This study investigated the impact of incorporating Aloe vera gel (AVG) and Aloe vera leaf skin (AVLS) extracts into edible coating (EC) on retarding lipid oxidation and enhancing the quality characteristics of cooked ground chicken meat during 14 days of storage at 4 °C. The results indicated that both AVG and AVLS extracts had a similar amount of total phenolic contents. EC application resulted in a decrease in pH values, and an increase in aw values. The addition of 2% AVG or AVLS extracts into EC formulation also decreased TBARS and ORP values. Although textural properties were not affected by EC application containing AVG or AVLS extracts, this application retarded L*, a*, and b* color values. The results indicated that Aloe vera extracts may be incorporated into EC by processors to improve lipid oxidation inhibition and maintain the quality characteristics of poultry meat products during refrigerated storage.

Efficacy of a novel combination of aloe vera gel and pineapple extracts in improving post-extraction pain and healing: A Randomized Controlled Trial.

Absorbable gelatin sponges are able to reduce the incidence of post-extraction complications when soaked with antimicrobial agents. However, the drawbacks associated with the injudicious use of antibiotics warrant the need to explore alternatives to the existing drugs. Aim: The present study aimed to evaluate the efficacy of an absorbable gelatin sponge soaked in a combination of aloe vera and pineapple extracts in reducing post-operative pain and improving the healing rate following dental extractions. Patients aged 18 to 60 years undergoing a single dental extraction of a posterior tooth were provided with either plain absorbable gelatin sponge (control group) or absorbable gelatin sponge soaked in freshly prepared solution of aloe vera gel and pineapple extracts. The pain levels were measured after one, three, seven, and fourteen days post-extraction. The socket healing status was evaluated by Landry Turnbull and Howley Index after one and two weeks post-extraction respectively. The mean pain was significantly less (p<0.05) for patients in the experimental group on the 1st, 3rd, and 7th postoperative days as compared to the patients in the control group. No significant differences (p>0.05) were observed in the healing status between the two groups at any time interval. The present study found the combination of aloe vera gel and pineapple extracts to be effective in reducing post-operative pain following dental extractions. While the improvement in the healing rate failed to reach statistical significance in the present study, generally less inflammation was observed in sockets treated with absorbable gelatin sponge soaked in the a combination of aloe vera and pineapple extracts. Key words:Post-extraction pain, Socket healing, Aloe Vera, Bromelain.

Electro-chemical studies of Zn doped nickel oxide nanoparticles synthesized via solution combustion method using green and chemical fuels.

This study presents a new green solution combustion method (aloe vera gel extract as fuel) and chemical method (glucose as fuel) to synthesise Zn-doped nickel oxide nanoparticles (Zn:NiO NPs). The face centered cubic crystal structure (FCC) phase was validated by PXRD, while the produced samples' spongy, spherical, agglomerated, and porous characteristics were shown by electron microscopy. The energy band gap values of 4.21 eV and 4.09 eV, respectively, were deduced for green and chemically synthesized Zn:NiO NPs. The reversibility was demonstrated by cyclic voltammetry with a lower EO-ER value for the green-Zn:NiO electrode. The studies on electrochemical impedance confirmed strong conductivity for the NPs by demonstrating a low charge transfer resistance. The Zn:NiO NPs are easily convertible into a stable electrode material that may be used in supercapacitors. According to the findings, Zn:NiO is an economical and promising material for use in supercapacitors in the future.

Enhancing effects of Aloe vera gel extracts on the humoral and cellular immune response and growth performance in broiler chickens.

The experiment evaluated how Aloe vera gel (AVG) extract supplementation affected immune responses and physiological performances in broiler chickens. 90-day-old Cobb 500 broiler chicks were reared for 38 days without the addition of antibiotics, either through feed or water. At 10 days, chicks were allocated into three groups: A, B, and C (n = 30). Group A served as non-supplemented control. Groups B and C were administered aqueous extracts of AVG at 1.0% and 2.0%, respectively, with drinking water. The supplementation of AVG potentiated the chicken immune response to Newcastle disease-vaccinated birds and sheep red blood cell-treated birds, which detected the highest antibody titers against Newcastle disease virus and sRBC. The cellular immune response evaluated through a cutaneous basophilic hypersensitivity test using phytohemagglutinin-P demonstrated a significant increase in skin thickness in AVG-supplemented birds. The relative sizes of lymphoid organs (bursa, spleen, and thymus) were significantly enhanced (p < 0.05) among the groups. Broilers given AVG-1 and AVG-2 exhibited significantly greater (p < 0.01) live body weight, dressing percentages, and serum protein and serum albumin levels. The supplemented groups experienced a significant reduction in total serum cholesterol, triglycerides, and low-density lipoprotein-cholesterol values, while the levels of high-density lipoprotein-cholesterol remained unchanged. The dietary aqueous extracts of AVG are effective in enhancing innate and specific immunity. This work strengthens the perspective of the use of AVG as an immune stimulant to facilitate recovery from immune suppression states, enhance innate and specific immunity, and improve broiler growth performance.

In silico docking studies of alpha-amylase inhibitors from the methanol extract of Aloe vera

In the current study, potent inhibitors of a-amylase, one of the significant regulating enzymes in diabetes, were identified from the methanolic extract of Aloe barbadensis miller (Aloe vera), an indigenous herbal plant used to treat carbohydrate absorption problems such as diabetes and obesity. The Aloe vera gel extract was dried, ground, macerated with methanol and subjected to phytochemical screening, which was characterized by gas chromatography. Since there is a rapid increase in computational methods to predict the association between two molecules, molecular docking studies assessed the effect of AVM (Aloe vera methanol) extract in inhibiting the enzyme alpha-amylase. The molecules derived from GC-MS analysis were employed as ligands for the receptor α-amylase in molecular docking experiments. The protein target used in this study was the human pancreatic α-amylase with PDB-ID -2QV4. The protein target and ligand structures were obtained from PDB and Pubchem databases respectively and docking studies were performed using PyRx. In this study, we intended to find distinct phytochemical substances from the Aloe vera plant as α-amylase inhibitors with an objective that the molecular docking studies provided in this study might result in the discovery of effective α-amylase inhibitors for diabetic management.
