Green Human Resource Management Bibliometric Analysis of the Published Literature from 2008 to 2022

Purpose:  The rising amount of research being done in the realm of environmental protection has resulted in the establishment of a new research paradigm in the field of human resource administration (HRA) called green human resource management" (GHRM). The current study was conducted to highlight the work been done in the field of GHRM and provide a pictorial view to the readers to understand the effectiveness of GHRM in various organizations.   Theoretical framework:  This paper provides an explanation of the development of literature and makes it possible to comprehend the topics that have been investigated in previous works of literature regarding GHRM.   Design/methodology/approach:  The Scopus core-collection and VOS-viewer were utilized in the writing of this paper. For the purpose of the study, each and every GHRM related document that will already exist within the database between 2008 till 2022 will be analyzed. The display of the data via graphical visualization incorporates both bibliographic coupling and co-citation features into the presentation.   Findings:  It was discovered that 418 documents on the GHRM scholarship were evaluated in this bibliometric investigation. The purpose of this study was to examine the volume, rising tendency, worldwide distribution, major journals, pioneer authors, dominant countries, and dominant industries in the field of global human resource management. With the use of logical operators, six different word combinations were combined to create the final product, “TITLE-ABS-KEY ("green human resource management" OR "green hr" OR "green human resource" OR " green human resource practices" OR "GHRM" OR "GHRMP")”, thus, the range grows wider. In the review, it was found that the GHRM is still a new idea. This review is meant to help modern researchers by giving them an overview of the current state of things.   Research, Practical & Social implications:  A more thorough and objective knowledge structure evolution framework for the period 2008 to 2022 is provided by this research, which is useful to the evolution of the Human Resource Management field.   Originality/value:  We have added a global perspective to our understanding of the concept's evolution across time by weaving together bibliographic information and network diagrams in this paper

Feasibility of elastomeric composites as alternative materials for marine applications: A compendious review on their properties and opportunities

© IMechE 2022. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1177/14750902221095321The term elastomer is a curtailment of two words, which are elastic and polymers. Accordingly, elastomers are polymer materials with elasticity. The significant challenges hindering the development of materials for naval applications, similar to other engineering sectors, include achieving a competitive light elastomeric structure. Marine structures are susceptible to various damage responses due to various loads throughout their service life. Being flexible, elastomer has a low modulus of elasticity, exhibits higher values of failure strain and yield strength. In these regards, elastomers are attractive materials for applications that require elasticity because they offer substantial advantages compared to traditional materials. However, the low fire resistance of these elastomeric materials jeopardizes their use in some critical applications. As a result, elastomeric blends and composites containing flame retardant (FR) additives are commonly used. On the other hand, elastomers possess (i) high strength-to-weight ratio, (ii) excellent impact properties, (iii) low infrared, magnetic, and radar signatures, (iv) excellent durability, and (v) high resilience to extreme loads. Hence, the scope of this study focuses on review and awareness regarding the feasibility of marine applications of elastomers/ elastomeric composites, their current scientific and technological drawbacks, and future outlooks or prospects to support several applications in the marine industry.Peer reviewe

Characterization of raw and alkali treated new natural cellulosic fibers from Tridax procumbens

The aim of this study is to investigate natural cellulosic fibers extracted from Tridax procumbens plants. The obtained fibers were alkali treated for their effective usage as reinforcement in composites. The physical, chemical, crystallinity, thermal, wettability and surface characteristics were analyzed for raw, and alkali treated Tridax procumbens fibers (TPFs). The test results conclude that there was an increase in cellulose content with a reduction in hemicellulose, lignin, and wax upon alkali treatment. This enhanced the thermal stability, tensile strength, crystallinity, and surface roughness characteristics. The contact angle was also lesser for treated TPFs which prove its better wettability with the liquid phase. The Weibull distribution analysis was adopted for the analysis of the fiber diameter and tensile properties. Thus the considerable improvement in the properties of alkali treated TPFs would be worth for developing high-performance polymer composites

Natural Fillers as Potential Modifying Agents for Epoxy Composition: A Review

Epoxy resins as important organic matrices, thanks to their chemical structure and the possibility of modification, have unique properties, which contribute to the fact that these materials have been used in many composite industries for many years. Epoxy resins are repeatedly used in exacting applications due to their exquisite mechanical properties, thermal stability, scratch resistance, and chemical resistance. Moreover, epoxy materials also have really strong resistance to solvents, chemical attacks, and climatic aging. The presented features confirm the fact that there is a constant interest of scientists in the modification of resins and understanding its mechanisms, as well as in the development of these materials to obtain systems with the required properties. Most of the recent studies in the literature are focused on green fillers such as post-agricultural waste powder (cashew nuts powder, coconut shell powder, rice husks, date seed), grass fiber (bamboo fibers), bast/leaf fiber (hemp fibers, banana bark fibers, pineapple leaf), and other natural fibers (waste tea fibers, palm ash) as reinforcement for epoxy resins rather than traditional non-biodegradable fillers due to their sustainability, low cost, wide availability, and the use of waste, which is environmentally friendly. Furthermore, the advantages of natural fillers over traditional fillers are acceptable specific strength and modulus, lightweight, and good biodegradability, which is very desirable nowadays. Therefore, the development and progress of “green products” based on epoxy resin and natural fillers as reinforcements have been increasing. Many uses of natural plant-derived fillers include many plant wastes, such as banana bark, coconut shell, and waste peanut shell, can be found in the literature. Partially biodegradable polymers obtained by using natural fillers and epoxy polymers can successfully reduce the undesirable epoxy and synthetic fiber waste. Additionally, partially biopolymers based on epoxy resins, which will be presented in the paper, are more useful than commercial polymers due to the low cost and improved good thermomechanical properties
