Application of nano-urea in conventional flood-irrigated Boro rice in Bangladesh and nitrogen losses investigation.

Bangladesh stands third in global rice production while complete modernization of rice production is not fully enforced. The boon of nano agriculture might circumvent the challenge of increasing the yield with minimal ecological damage. Nanofertilizer might be one of the solutions to address the problem of modern agriculture confronting environmental hazards owing to the excessive use of synthetic fertilizers by farmers in Bangladesh.

Lignin Nanoparticles as pH-responsive Nanocarriers for Gastric-Irritant Oral Drug Aspirin.

Introduction: Although lignin is one of the most naturally abundant biopolymers, the overall status of its utilization has long been subpar. The ability of Lignin to readily self-assemble into nanoparticles, along with its good biocompatibility and minimal toxicity, makes it a perfect agent for nanocarriers and drug delivery.

Method: Hence, in this study, we have attempted to examine lignin nanoparticles (LNPs) as an efficient pH-responsive nanocarrier for gastric-irritant oral NSAID, aspirin.

Synthesis, Activation, and Characterization of Carbon Fiber Precursor Derived from Jute Fiber.

Activated carbon (AC) fiber is a carbonaceous material with a porous structure that has a tremendous scope of application in different fields. Conventionally, AC is derived from fossil fuel-based raw materials like polyacrylonitrile (PAN) and pitch. In this work, AC was synthesized from eco-friendly, renewable, and ubiquitous jute fiber.

Performance evaluation of dextran-coated CaFeO/MnFeO exchange-spring composites for the self-heating properties at radio frequency field.

The CaFeO/MnFeO composites with the hard (CaFeO) and soft (MnFeO) magnetic phases, were prepared by chemical co-precipitation method. The prepared composites were calcined at three different temperatures to form different phases. The structural, morphological, and magnetic properties of composite were analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), room temperature vibrational sample magnetometer (VSM), and transmission electron microscopy (TEM).

Superior Cyclic Stability and Capacitive Performance of Cation- and Water Molecule-Preintercalated δ-MnO/h-WO Nanostructures as Supercapacitor Electrodes.

The large number of active sites in the layered structure of δ-MnO with considerable interlayer spacing makes it an excellent candidate for ion storage. Unfortunately, the δ-MnO-based electrode has not yet attained the exceptional storage potential that it should demonstrate because of disappointing structural deterioration during periodic charging and discharging. Here, we represent that stable Na ion storage in δ-MnO may be triggered by the preintercalation of K ions and water molecules.

Evaluation of chitosan-Ag/TiO nanocomposite for the enhancement of shelf life of chili and banana fruits.

Post-harvest losses of fruits and vegetables account for a large share of food waste in the world due to improper handling and packaging. By using the sol-gel method, Ag/TiO nanocomposite was prepared in this study from micro-sized commercial TiO powder and incorporated in a chitosan-cellulose matrix for the purpose of promising food packaging. The particle size and distribution of Ag nanoparticles (9.

Progeny Transfer Effects of Chitosan-Coated Cobalt Ferrite Nanoparticles.

Cobalt ferrite nanoparticles (CFNs) are promising materials for their enticing properties for different biomedical applications, including magnetic resonance imaging (MRI) contrast, drug carriers, biosensors, and many more. In our previous study, a chitosan-coated CFN (CCN) nanocomplex demonstrated potential as an MRI contrast dye by improving the biocompatibility of CFN. In this study, we report the progeny transfer effects of CCN following a single intravenous injection of CCN (20, 40, or 60 mg/kg) in pregnant albino Wistar rats.

Evaluation of a novel nanocrystalline hydroxyapatite powder and a solid hydroxyapatite/Chitosan-Gelatin bioceramic for scaffold preparation used as a bone substitute material.

Artificially fabricated hydroxyapatite (HAP) shows excellent biocompatibility with various kinds of cells and tissues which makes it an ideal candidate for a bone substitute material. In this study, hydroxyapatite nanoparticles have been prepared by using the wet chemical precipitation method using calcium nitrate tetra-hydrate [Ca(NO).4HO] and di-ammonium hydrogen phosphate [(NH) HPO] as precursors.

Manganese Ferrite Nanoparticles (MnFeO): Size Dependence for Hyperthermia and Negative/Positive Contrast Enhancement in MRI.

We synthesized manganese ferrite (MnFeO) nanoparticles of different sizes by varying pH during chemical co-precipitation procedure and modified their surfaces with polysaccharide chitosan (CS) to investigate characteristics of hyperthermia and magnetic resonance imaging (MRI). Structural features were analyzed by X-ray diffraction (XRD), high-resolution transmission electron microscopy (TEM), selected area diffraction (SAED) patterns, and Mössbauer spectroscopy to confirm the formation of superparamagnetic MnFeO nanoparticles with a size range of 5-15 nm for pH of 9-12. The hydrodynamic sizes of nanoparticles were less than 250 nm with a polydispersity index of 0.

Mesoporous electromagnetic composite particles: Electric current responsive release of biologically active molecules and antibacterial properties.

Electric current responsive magnetic composite particles are prepared in three steps. In the first step, spherical and mesoporous submicrometer-sized magnetic iron oxide (FeO) core particles are prepared by solvothermal method. Then magnetic FeO particles are functionalized with amine groups using glycine, where the COO- group of glycine formed a bridging bidentate interaction with the hydroxyl groups on FeO particle surface.

Mesoporous magnetic silica particles modified with stimuli-responsive P(NIPAM-DMA) valve for controlled loading and release of biologically active molecules.

Mesoporous magnetic silica particles bearing a stimuli-responsive polymer valve were prepared and their performance as a microcapsule was evaluated. In this study, first, mesoporous magnetic iron oxide (Fe3O4) particles were prepared by a solvothermal method. Then, the magnetic particles were coated with silica and functionalized with vinyl groups using 3-(trimethoxysilyl)-propyl methacrylate (MPS).
