SRI, or socially responsible investment, is a relatively new concept used to describe an investment that considers social, ethical, and environmental concerns. The purpose of this study is to investigate if collectivism, concern for the environment, financial performance, and awareness of SRI influence an individual’s propensity to invest in socially responsible investments (SRI). Secondly, the study evaluates the influence of the TPB (Theory of Planned Behavior) model constructs, attitude, subjective norms, and perceived behavioral control on the SRI investment intention of individual investors. A structured questionnaire was used to collect data on 449 individual investors for this cross-sectional investigation. The data were then analyzed further with a two-step structural equation modeling technique performed in Smart PLS 3.2.9. The PLS-SEM analysis found that collectivism, environmental concerns, financial performance, and awareness of SRI all had significant positive effects on attitudes toward SRI, which, in turn, resulted in SRI investment intention. Further, subjective norms and perceived behavioral control had a significant impact on individuals’ intentions regarding SRI.

Global consumption trends point to rising demand for organic food as people become more health-conscious. The factors that people consider while making initial organic purchases have been discussed at length. However, the published research is scant about the factors that affect consumers’ propensity to repurchase organic goods. The present research fills this gap by focusing on what influences consumers’ decisions to repurchase organic grain. The Stimulus-Organism-Response (S-O-R) theory and the Theory of Planned Behaviour are the theoretical foundations of the present investigation. The consumer’s attitude toward organic grains and their desire to repurchase organic grains are influenced by health consciousness and previous experience. The repurchase intent was determined to be controlled by the buyer’s willingness to pay and their level of trust in the organic grain. This cross-sectional study collected the necessary data from five chosen urban centres in India. Smart PLS 3.2.9 was used to analyse the gathered data from 463 respondents. According to the findings, health consciousness and past experience favourably influence attitudes and repurchase intent. The trust that consumers have built up in organic grain as a result of past experiences is what drives their desire to make more purchases. Willingness to pay significantly controls and impacts the inclination to repurchase. The association between health consciousness and repurchase intention is partially mediated by attitude, as is the relationship between past experience and repurchase intention. The relationship between health consciousness and the desire to repurchase is partially mediated by the willingness to pay.

The incorporation of carboxyl functionalized multi-walled carbon nanotube (MWCNT- COOH) into a polymethyl methacrylate (PMMA) has been investigated. The resultant tensile and flexural mechanical properties have been determined. In this paper, a novel synthesis process for a MWCNT-reinforced polymer nanocomposite is proposed. The proposed method significantly eliminates the most challenging issues of the nano-dispersed phase, including agglomeration and non-homogeneous mixing within a given matrix material, and also resolves the issues occurring in conventional mixing processes. The results of scanning electron microscopy support these claims. This 3D-mixing process is followed by an extrusion process, using a twin-screw extruder for pristine MWCNT, and a compression molding process for COOH-MWCNT, to prepare test specimens for experimentally determining the mechanical properties. The test specimens are fabricated using 0.1, 0.5, and 1.0 wt.% MWCNT, with a remaining PMMA phase. The testing is conducted according to ASTM D3039 and ASTM D7264 standards. Significant improvements of 25.41%, 35.85%, and 31.75% in tensile properties and 18.27%, 48%, and 33.33% in flexural properties for 0.1, 0.5, and 1.0 wt.% COOH-MWCNT in PMMA, respectively, compared to non-functionalized MWCNTs, were demonstrated. The highest strength was recorded for the nanocomposite with 0.5 wt.% f-MWCNT content, indicating the best doping effect at a lower concentration of f-MWCNT. The proposed CNT-PMMA nanocomposite may be found suitable for use as a scaffold material in the domain of bone tissue engineering research. This type of research possesses a high strength requirement, which may be fulfilled using MWCNT. Furthermore, this analysis also shows a significant amount of enhancement in flexural strength, which is clinically required for fabricating denture bases.

Joining immiscible materials such as copper and stainless steel together is a significant concern due to distinct mechanical and metallurgical properties across the joint line, such as melting points, the coefficient of linear thermal expansion, and thermal conductivity. The joint properties of copper to stainless steel welds are in great demand for various mechanical components of the international thermonuclear experimental reactor, ultra-high vacuum system, plan wave linear-accelerator or linac structure, and heat exchanger. These dissimilar-metals joints offer excellent flexibility in design and production, leading to a robust structure for many cutting-edge applications. Hence, the present article reviews the copper to stainless steel joining mechanism under different solid-state processing conditions. The present understanding says that defect-free strong joints between the dissimilar metals are systematically possible. Apart from this understanding, the authors have identified and highlighted the gaps in the research exploration to date. Moreover, a sustainable methodology to achieve a desirable weld of copper to stainless steel depends on favorable processing conditions.
