Abstract Bio-fortification is a potential technique to tackle micronutrient deficiencies that remain. Wheat grain bio-fortification has the ability to decrease malnutrition because it represents one of the most essential staple crops. Bio-fortification is cost-effective and evidence-based sustainable technique to address malnutrition in wheat varieties possessing additional micronutrient contents. Nano-biofortification is a novel approach, enriching crops with essential nutrients in order to supplement human diets with balanced diets. The current study was designed to explore the potential role of phytogenic iron nanoparticles (Fe-NPs) to enhance nutritional contents in wheat plants to fulfill the nutrient deficiency important for human and animal health. In the current study, Fe-NPs were fabricated by using the extract of Mentha arvensis L. that were irregular in shape with an approximate size range of 40–100 nm. Further, Fourier transform infrared (FT-IR) analyses were deployed to confirm the presence of t of various functional groups involved in the green and eco-friendly fabrication of Fe-NPs. The effects of phytogenic Fe-NPs were examined on various physiological and biochemical parameters such as total proline, total chlorophyll, carbohydrates, protein, crude fibers, and lipids contents. Moreover, wheat physiological and biochemical profiling was carried out, and it was noticed that Fe-NPs significantly altered the physico-biochemical profiling of wheat plants. Multiple methods of administration of Fe-NPs were used to fortify the wheat crop. However, the Fe-NPs assisted seed priming along with foliar applications at various concentrations (10, 20, and 30 mg·L−1) were found more suitable to enhance the contents of proline, Chlorophyll a, b, total chlorophyll, carbohydrate, proteins, fibers, and lipids (20.22%, 18.23%, 17.25%, 16.32%, 12.34%, 24.31%, 19.52%, and 11.97%, respectively) in wheat plants. Further, wheat flour was exposed to digestive enzymes, with the iron content gradually increased in a dose-dependent manner. The nutritional analysis of wheat zinc (Zn), molybdenum (Mo), magnesium (Mg), iron (Fe), yttrium (Y), and copper (Cu) and the fatty acid profile have demonstrated divergent patterns of behavior. Similarly, iron content was also increased significantly in response to the exposure to Fe-NPs.

Abstract This study assessed the protective effect of citrus flavanone, naringin (Nar), and its nanoformulation against di(2-ethylhexyl)phthalate (DEHP) toxicity in albino rats. Keeping green nanotechnology as the cornerstone, nanoparticles of Nar were synthesized and characterized using electron microscopy (transmission electron microscopy and scanning electron microscopy), particle size distribution, Fourier transform infrared spectroscopy, and X-ray diffraction. The synthesized nanoparticles were primarily spherical with an average size of 109 nm and a low polydispersity index of 0.175. Mature male albino rats were used for the exposure study. Group I was negative control. Groups II, III, and IV were exposed to (250 mg·kg b·wt−1) DEHP for 3 weeks. Group III was treated with bulk Nar (5 mg·kg b·wt−1), and group IV was treated with non-naringin (NNar) (5 mg·kg b·wt−1). Group V was exposed only to NNar. Exposure to DEHP significantly enhanced serum levels of pro-inflammatory cytokines, interleukin-1β, 6, 8 (IL-1β, IL-6, IL-8), and tumour necrosis factor (TNF-α). In addition, the repression of hepatic mRNA expression of nuclear factor-erythroid 2-related factor 2 was also observed. In addition, marked histopathological alterations were observed in the hepatic and renal tissues. Treatment with both Nar and NNar significantly alleviated the DEHP-induced oxidative stress/inflammatory response along with the associated histological alterations. However, therapeutic utility of NNar was more profound underlining its potential in nutraceutical therapeutics with high green credentials.

Abstract Mosquito vectors in the present universe cause a major problem due to the transmission of pathogens with high morbidity. The present research aimed to explore the larvicidal and adulticidal toxicity of the Cladostepus spongiosus extract and its fabricated AgNPs on key mosquito vectors. The synthesized AgNPs were confirmed by UV-Vis spectroscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectrophotometry, and X-ray diffraction analysis. In the mosquitocidal assay, the C. spongiosus extract has shown good larvicidal mortality against Aedes aegypti (88.9%), Anopheles stephensi (84.1%), and Culex. quinquefasciatus (81.6%). Further, adulticidal mortality percentages were 78.8%, 75.4%, and 67.6% against An. stephensi, Ae. Aegypti, and Cx. quinquefasciatus at 1,000 ppm. AgNPs revealed larvicidal mortality percentages of 94.8% against An. stephensi, 92.8% against Ae. Aegypti, and 90.6% against Cx. quinquefasciatus; the adulticidal potential was also revealed to be higher against An. stephensi (89.4%) followed by Ae. aegypti (86.8%) and Cx. quinquefasciatus (83.2%). Comparing the results achieved from the C. spongiosus extract and its derived AgNPs, promising activity was attained against key mosquito vectors at a minimal dose of 70 ppm of AgNPs. Thus, C. spongiosus-mediated AgNPs can be an alternative tool in controlling key mosquito vectors.

Abstract Solanum nigrum and Mentha leaf extracts were used as reducing and stabilizing reagents in the green synthesis of silver oxide nanoparticles (AgO NPs), and their antibacterial efficacy was subsequently evaluated. The structure and morphology of AgO NPs were evaluated using X-ray diffraction and filed emission scanning electron microscope. High-resolution transmission electron microscopy images were used to analyze the characteristics of certain particles with clearly discernible atomic structures. The functional group and elemental composition of AgO NPs were investigated using fourier transform infrared spectroscopy and energy dispersive X-ray spectroscopy. Ultraviolet–visible spectroscopy was used to determine the energy band gap ( E g ) of the sample. The dielectric constant of both samples was found to be inversely proportional to frequency, whereas the dielectric loss was found to be directly proportional to temperature but directly proportional to frequency. This suggests that the space charge has an effect on the mechanism of charge transfer as well as polarizability. AC conductivity rises and is inversely proportional to temperature increases. AgO NPs had a size range of around 56 nm and were mostly spherical. The antibacterial potential of the synthesized AgO NPs using both extracts was compared by the well-diffusion method. AgO NPs at 50–100 µg·mL −1 concentration significantly inhibited the bacterial growth of Bacillus cereus , Staphylococcus aureus , Escherichia coli , and Klebsiella pneumonia .

Abstract Ce and F were added to MCM-48 molecular sieve by hydrothermal synthesis, and Pd/Ce(F)-MCM-48 metal acid bifunctional catalysts were prepared by impregnation method. The physical and chemical properties of Ce(F)-MCM-48 and Pd/Ce(F)-MCM-48 were characterized by X-ray diffraction, scanning electron microscope, NH 3 temperature programmed desorption instrument, Fourier infrared spectrometer, and X-ray photoelectronic spectrometer characterization methods. The results showed that when the molar ratio of the raw materials was n (Ce): n (TEOS) = 0.02 and n (NaF): n (TEOS) = 0.10, Ce(F)-MCM-48-0.10 molecular sieve had a high degree of order and large specific surface area and pore volume, the total acid content increased, and the acid strength also increased. And it had an acidic center and generated certain oxygen vacancies. The catalyst prepared after Pd impregnation had good dispersibility. 0.4% Pd/Ce(F)-MCM-48-0.10 catalyst still maintained the crystalline phase of MCM-48 molecular sieve. A micro-reaction device was used to examine the catalytic performance of n -heptane isomerization of Pd/Ce(F)-MCM-48-0.10 catalysts. When the hydrogen flow rate was 30 mL·min −1 , reduction temperature was 300°C, reduction time was 4 h, weight hourly space velocity was 7.6 h −1 , and reaction temperature was 280°C, 0.4% Pd/Ce(F)-MCM-48-0.10 catalyst was used in the heptane isomerization reaction, where the conversion of n -heptane was 67.3% and the selectivity of isoheptane was 96.5%.
摘要采用水热合成法将Ce和F加入到MCM-48分子筛中，采用浸渍法制备了Pd/Ce(F)-MCM-48金属酸双功能催化剂。采用x射线衍射、扫描电镜、nh3程序升温解吸仪、傅里叶红外光谱仪、x射线光电子能谱等表征方法对Ce(F)-MCM-48和Pd/Ce(F)-MCM-48的理化性质进行了表征。结果表明，当原料的摩尔比为n (Ce): n (TEOS) = 0.02和n (NaF): n (TEOS) = 0.10时，Ce(F)-MCM-48-0.10分子筛有序度高，比表面积和孔体积大，总酸含量增加，酸强度也有所提高。它有一个酸性中心并产生了一定的氧空位。钯浸渍后制备的催化剂具有良好的分散性。0.4% Pd/Ce(F)-MCM-48-0.10催化剂仍保持MCM-48分子筛的结晶相。采用微反应装置考察了Pd/Ce(F)-MCM-48-0.10催化剂对正庚烷异构化的催化性能。在氢流量为30 mL·min−1、还原温度为300℃、还原时间为4 h、失重时空速为7.6 h−1、反应温度为280℃的条件下，采用0.4% Pd/Ce(F)-MCM-48-0.10催化剂进行庚烷异构化反应，正庚烷转化率为67.3%，异庚烷选择性为96.5%。

Abstract An efficient one-pot route leading to bis-indolizine symmetric compounds has been developed via a new approach from the dipyridinium heterocyclic compound, reactive halogenated derivative, and activated alkyne through biocatalysis. A set of local plants was evaluated for its catalytic potential in “one-pot” biocatalysis of these valuable fluorescent compound synthesis reactions. Most of these biocatalysts containing enzymes from the oxidoreductase class (peroxidase: 0.56–1.08 mmol purpurogallin‧g −1 fresh weight‧min −1 , polyphenol oxidase (PPO) : 27.19–48.95 PPO units‧mg tissue −1 , CAT: 3.27–21.71 µmol O 2 ‧g −1 fresh weight‧min −1 ), were used as green catalysts in the multi-component cycloaddition reaction, in an aqueous buffer solution, for the production of bis-indolizine compounds in moderate to excellent yields (45–85%). The horseradish root ( Armoracia rusticana ) has been selected as the most promising biocatalyst source among the evaluated plants, and the obtained yields were greater than in the conventional synthesis method. The structures of indolizine derivatives were confirmed by nuclear magnetic resonance spectra, elemental analyses, as well as Fourier transform-infrared spectra. The cytotoxicity of the latter obtained indolizine compounds on the growth of the model microorganism, Saccharomyces cerevisiae MIUG 3.6 yeast strain, was also evaluated. Various parameters (number of generations, growth rate, generation time, dry matter yield, the degree of the budding yeast cells, and the degree of yeast autolysis, fermentation intensity), which describe the yeast growth, suggest that the nutrient broth supplemented with different concentrations of bis-indolizine compounds (10 and 1 µM) had no toxic effect on the yeast strain growth, under submerged cultivation conditions.

Abstract Kitchen waste contains high contents of organic matter and moisture, and it is prone to biodegrade and decompose to give odors. If not collected and transported promptly or treated improperly, it is highly likely to pollute the environment and spread diseases. Because the lipid content in kitchen waste is high and a portion of organic matter is not subject to hydrolysis, the development of anaerobic digestion technology has been greatly limited. Kitchen waste was pretreated with NaOH, KOH, and Ca(OH) 2 with different concentrations, and 50 days sequencing batch mesophilic anaerobic digestion experiments were conducted. This study sheds light on the pollution reduction and energy generation of kitchen waste. The results are as follows: (1) The lipid content of kitchen waste could be reduced, and the concentration of dissolved organic matter could be increased by pretreating with alkali. The degradation rate of kitchen waste lipid reached a maximum of 50.51%, if 3% NaOH was added, and the soluble chemical oxygen demand concentration was increased by 235.3%. (2) The cumulative methane (CH 4 ) output and biogas production efficiency were improved in the anaerobic digestion process with kitchen waste pretreated with alkali. The maximum daily gas output of kitchen waste pretreated with NaOH and KOH took place on the 11th to 12th day, with the biogas production efficiency of 40.4 and 45.2 mL·g·VS −1 . The cumulative CH 4 output was increased from 370.2 mL·g·VS −1 (untreated) to 393.1 and 434.1 mL·g·VS −1 , respectively. In addition, the concentration of CH 4 in biogas was increased from 54.8% (untreated) to 59.1% and 61.7%, respectively. (3) The Chao1 and Ace values of bacteria were increased first and then decreased. On the 10th day, the diversity of bacteria reached the highest value, and on the 20th day, the diversity of archaea reached its maximum.

If not collected and transported promptly or treated improperly, it is highly likely to pollute the environment and spread diseases. Because the lipid content in kitchen waste is high and a portion of organic matter is not subject to hydrolysis, the development of anaerobic digestion technology has been greatly limited. Kitchen waste was pretreated with NaOH, KOH, and Ca(OH) 2 with different concentrations, and 50 days sequencing batch mesophilic anaerobic digestion experiments were conducted. This study sheds light on the pollution reduction and energy generation of kitchen waste. The results are as follows: (1) The lipid content of kitchen waste could be reduced, and the concentration of dissolved organic matter could be increased by pretreating with alkali. The degradation rate of kitchen waste lipid reached a maximum of 50.51%, if 3% NaOH was added, and the soluble chemical oxygen demand concentration was increased by 235.3%. (2) The cumulative methane (CH 4 ) output and biogas production efficiency were improved in the anaerobic digestion process with kitchen waste pretreated with alkali. The maximum daily gas output of kitchen waste pretreated with NaOH and KOH took place on the 11th to 12th day, with the biogas production efficiency of 40.4 and 45.2 mL·g·VS −1 . The cumulative CH 4 output was increased from 370.2 mL·g·VS −1 (untreated) to 393.1 and 434.1 mL·g·VS −1 , respectively. In addition, the concentration of CH 4 in biogas was increased from 54.8% (untreated) to 59.1% and 61.7%, respectively.

Abstract The purpose of the study was to determine whether lake sediments could be a potential raw material for the plastics industry. The examined samples were obtained in a complex process of sediment collection from Lake Swarzędzkie located in the region of Wielkopolska, Poland, followed by granulometric analysis by sieving and quartz grain shape analysis, with preparation of geotechnical sheets. The works involved the examination of physico-chemical characteristics of carbonate lake sediments and the analysis of impact of the sediments’ depth extraction on their chemical composition and physico-chemical properties. The lake sediment consists mainly of calcium carbonate (CaCO3) and can be a potential filler for plastics. Tests were carried out to determine chemical composition of the sediments and their thermal stability. The thermogravimetric analysis showed the three stages of the thermal decomposition. Sediments in deeper layers of the lake are characterised by the presence of not only CaCO3 and silica, but also other chemical compounds, including aluminosilicates. In addition, as the depth increases, the average size of sediment particles changes, with the main fraction particle size being the smallest for the material from the 6–12 m depth. Additionally, carbon content systematically decreases with increasing depth.

Abstract In the present work, the disk-shaped zinc oxide (ZnO) nanoparticles were synthesized and functionalized with β-cyclodextrin (β-CD) and nicotinic acid (vitamin B3) using the wet co-precipitation method. The functionalized ZnO/β-CD/nicotinic acid nanocomposite materials were characterized using UV-visible spectroscopy (UV-Vis), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), field emission electron microscopy (FESEM), and band-gap energy analysis. The band gap value (E g) was 4.3 eV. The average XRD crystallite size was determined using the Scherrer formula and was found to be 50 nm. The ZnO/β-CD/nicotinic acid nanocomposite material showed a photocatalytic effect for dye-polluted wastewater. It also showed an antibacterial effect against the Gram-positive bacterial strain Streptococcus aureus (S. aureus) but did not show any antibacterial activity with Gram-negative Escherichia coli (E. coli). The ZnO/β-CD/nicotinic acid nanocomposite also showed antifungal activity with Aspergillus niger (A. niger). It was noticed that ZnO/β-CD/nicotinic acid nanocomposite showed efficient anticancer activity with IC50 = 14.95 µg·mL−1 in MCF-7 cell lines. Because of the formation of singlet oxygen (O2˙−) and hydrogen oxide radical (–OH˙), the composite material showed a photodegradation reaction against aq. solution of methylene blue dye. After 190 min, the blue colour of aq. solution methylene blue was decolourized at 6 pH at a constant time interval.

Abstract Worldwide, epilepsy is the second most prevalent neurological disorder. Disappointingly, various adverse effects are being observed with currently used antiepileptic drugs. Nanomedicine represents an effective strategy to overcome these limitations with a better central drug delivery. Hence, our work aimed to unravel the antiepileptic efficacy of rutin (Rut) loaded with selenium nanoparticles (SeNPs) against pentylenetetrazole (PTZ)-challenged mice. Ten days before PTZ (60 mg·kg−1) intraperitoneal injection, mice were orally administered Rut (100 mg·kg−1), sodium selenite (0.5 mg·kg−1), SeNPs (100 mg·kg−1), or sodium valproate (reference drug, 200 mg·kg−1). Remarkably, administration of Rut-loaded SeNPs (Rut-SeNPs) to epileptic mice markedly increased the latency time and decreased the severity and duration of seizures. Remarkable increases were also noticed in acetylcholinesterase, brain-derived neurotrophic factor, dopamine, and norepinephrine levels in epileptic mice treated with Rut-SeNPs. Furthermore, Rut-SeNPs boosted the cellular antioxidant defense by increasing superoxide dismutase, catalase, GSH, Nrf2, and HO-1, along with decreased malondialdehyde and nitric oxide levels. In addition, the nanotherapy successfully mitigated the inflammatory mediators (tumor necrosis factor-α, interleukin-6, cyclooxygenase-2, and nuclear factor kappa B) in mice hippocampus. Rut-SeNPs antagonized neuronal apoptosis by decreasing Bax and caspase-3 and increasing the levels of Bcl-2. Conclusively, the present work suggests Rut-loaded SeNPs as an effective antiepileptic therapy through correction of disturbed neurotransmitters, oxidative status, neuroinflammation, and apoptosis.
