ENHANCED MECHANICAL STRENGTH OF SOYBEAN OIL-BASED NON-ISOCYANATE POLYURETHANE ADHESIVE FOR WOOD APPLICATION BY INTRODUCING NANOFILLERS
Get PDFPolyurethane (PU) is a versatile material that finds extensive use in various industries including bedding, construction, automotive, and packaging. Historically, this particular polymer relied significantly on petrochemical resources, a practice that was considered to have negative environmental impacts. The conventional method for preparing PU involves the use of isocyanate, which is a disadvantage due to its negative impact on the environment and human health. The resolution of this problem entails identifying an appropriate substitute for petroleum-derived products that minimize their impact on both the environment and human health. The researchers earlier utilized soybean oil, for the formulation of PUs in this replacement [1]. Hence, researchers are consistently conducting experiments on non-isocyanate polyurethane (NIPU).
This study focuses on the preparation of non-isocyanate polyurethane for using as a wood adhesive. The process involved epoxidation, followed by carbonation, to produce carbonated soybean oil. The synthesized carbonated soybean oil (CSBO) was then blended with ethylenediamine (EDA) to produce a NIPU adhesive network. To analyze the synthesized CSBO, various confirmatory tests such as Fourier transform infrared spectroscopy (FT-IR), gel permeation chromatography (GPC), viscosity, iodine value, and epoxy value were conducted. The synthesized NIPU adhesive was characterized using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Furthermore, to investigate improvements in the thermal and mechanical characteristics of the green polyurethane glue, silicon (Si) nanoparticles were included as a filler, with different particle sizes of 100 nm, 200-300 nm, and 500 nm. In addition, to investigate the tensile strength of the NIPU adhesive, a single lap joint specimen was subjected to testing using a tensile testing instrument. To cure the specimen, a manual clamping technique was used, and specimens were then kept in the oven at various temperatures & times to achieve the ideal sample for further testing with fillers. With the control NIPU sample, 8.81 MPa of shear strength was recorded. As expected, after incorporating fillers in NIPU adhesive, the highest shear strength was achieved at 9.85 MPa. Apart from this, a contact angle test was also performed to observe the hydrophobicity of the sample. This work brought a facile path to produce NIPU adhesive from soybean oil which could be further used as a wood adhesive
MICROPLATE-LIKE METAL PYROPHOSPHATE ENGINEERED ON NI-FOAM TOWARDS MULTIFUNCTIONAL ELECTRODE MATERIAL FOR ENERGY CONVERSION AND STORAGE
Get PDFHigh clean energy demand, dire need for sustainable development, and low carbon footprints are the few intuitive challenges, leading researchers to aim for research and development for high-performance energy devices. The development of materials used in energy devices is currently focused on enhancing the performance, electronic properties, and durability of devices. Tunning the attributes of transition metals using pyrophosphate (P2O7) ligand moieties can be a promising approach to meet the requirements of energy devices such as water electrolyzers and supercapacitors, although such a material’s configuration is rarely exposed for this purpose of study.
Herein, we grow Ni2P2O7, Co2P2O7, and Fe2P2O7 composites on conductive Ni-foam using a hydrothermal procedure. The results indicated that, among all the synthesized samples, Fe2P2O7 exhibited outstanding oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) with the least overpotential of 220 and 241 mV to draw a current density of 10 mA/cm2. Further, wastewater rich in urea from sanitary units and industries is subjected to produce green energy through waste water-splitting. Thus, urea oxidation reaction (UOR) is the most widely promoted. We employed synthesized composites towards UOR investigation and it was found that Fe2P2O7 exhibits splendid performance with the low onset potential of 1.317 V (vs RHE) at 10 mA/cm2 of current density. The low Tafel slope, high turnover frequency, low charge transfer resistance, greater ECSA, and roughness factor contribute to enriching the performance of Fe2P2O7 as an effective electrocatalyst towards OER, HER, and UOR. Theoretical studies indicate that the optimal electronic coupling of the Fe site with the pyrophosphate enhances the overall electronic properties of Fe2P2O7, thereby, showing its electrocatalytic performance concerning freshwater and waste water-splitting. Moreover, the composite materials showed the best capacitive properties for supercapacitor energy storage applications. The specific capacitance offered by composite materials ranges from 8000-3000 mF/cm2 at 1 mA/cm2. Additionally, it possessed high capacitance retention and coulombic efficiency up to 5,000 charge/discharge cycles.
Consequently, this work suggests how to use pyrophosphate moieties to fabricate non-noble metal-based electrode materials to achieve good performance in electrocatalytic splitting water as energy conversion and supercapacitors as energy storage applications
Creating a Gifted-Friendly Classroom
Get PDFThe goal of undergraduate teacher preparation programs is to equip future teachers to work with all learners. Gifted and talented learners are likely found in every classroom regardless of where they reside. According to Rinn et al. (2022), Kansas, Missouri, Oklahoma, Colorado, and Nebraska do not require undergraduate teacher candidates to take university coursework on gifted education. The goal of this presentation is to provide a general overview of gifted education specific to Kansas. This presentation aims to address myths and misconceptions about gifted education and gifted learners, characteristics of gifted learners, a basic overview of a general identification process, and strategies to create a gifted-friendly classroom.https://digitalcommons.pittstate.edu/oer-teaching/1001/thumbnail.jp
