Graphene, an innovative nanocarbon, has been discovered as a significant technological material. Increasing utilization of graphene has moved research towards the development of sustainable green techniques to synthesize graphene and related nanomaterials. This review article is basically designed to highlight the significant sustainability aspects of graphene. Consequently, the sustainability vision is presented for graphene and graphene nanocomposites. Environmentally sustainable production of graphene and ensuing nanomaterials has been studied. The formation of graphene, graphene oxide, reduced graphene oxide, and other derivatives has been synthesized using ecological carbon and green sources, green solvents, non-toxic reagents, and green routes. Furthermore, the utilization of graphene for the conversion of industrial polymers to sustainable recycled polymers has been studied. In addition, the recycled polymers have also been used to form graphene as a sustainable method. The implication of graphene in the sustainable energy systems has been investigated. Specifically, high specific capacitance and capacitance retention were observed for graphene-based supercapacitor systems. Subsequently, graphene may act as a multi-functional, high performance, green nanomaterial with low weight, low price, and environmental friendliness for sustainable engineering and green energy storage applications. However, existing challenges regarding advanced material design, processing, recyclability, and commercial scale production need to be overcome to unveil the true sustainability aspects of graphene in the environmental and energy sectors.

The transfer of knowledge and the preservation of traditions is passed down from generation to generation. The main objective of this study was to explore people’s knowledge of the gastronomic heritage of the Kisalföld regions through an analysis of the county’s (attendance to, decision-making and willingness to spend on food and beverages) taking place in the county, such as the Flavours of Szigetköz, the County Wines Festival, the Flavours of Rábaköz or Eszterházy Baroque Food Festival at Fertőd. A quantitative research was used to analyse the topic (N = 666), the sample is not representative and the selection of respondents was random. Data were collected between 1 September 2023 and 31 October 2023 using electronic questionnaires shared on Google Drive. Data were processed using SPSS 25.0 and MS Office Excel in addition to the descriptive statistical data (modus, median, standard deviation), correlation, and crosstabulation analyses. Important research questions of the study were whether the respondents’ place of respondents influences gastronomic awareness whether age determines willingness to travel to attend a gastronomy event, The most popular gastronomic event in the county was the Vegetables of Hanság Region (mean 3.35), and the least popular was the Szigetköz Flavours of Szigetköz festival (mean 3.01). The key finding of the study is that an essential aspect of sustainability for decision-makers is to know the characteristics of tourists (middle-aged female target group), to select and maximize the different program packages in the marketing of the offer, to distribute the traffic and to avoid mass tourism.

High-quality implementation of cross-border mergers and acquisitions (cross-border M&As) is an important pathway for emerging-market multinational enterprises (EMNEs) to enhance their international competitiveness. However, in comparison to developed countries, cross-border M&As by EMNEs are often prohibited by the liability of origin caused by negative political coverage. How and why negative political coverage affect the completion of cross-border M&As by EMNEs? What are the contextual constraints that moderate the impact of negative political coverage on cross-border M&As completion? Based on the “liability of origin” theory, this paper addresses these questions using data from the Zephyr database on cross-border M&As by EMNEs in the United States from 2016 to June 2021 and employing a logit model for estimation. The research findings are as follows: (1) Negative political coverage leads to negative perceptions of emerging market countries by host country stakeholders, creating the liability of origin and stigmatizing the corporate nationality, thereby reducing the success rate of cross-border M&As by EMNEs. (2) Increasing geographical distance leads to information asymmetry, reinforcing the negative impact of negative political coverage on the completion of cross-border M&As by EMNEs. (3) Relevant mergers and acquisitions exacerbate the negative effect of negative political coverage on the success rate of cross-border M&As by EMNEs. (4) Being a publicly traded firm and having successful experience in cross-border M&As both intensify the negative impact of negative political coverage on the success rate of cross-border M&As by EMNEs.

The process of internationalization and innovation (IPI) in the urban road passenger transport (URPT) sector is driven by the need to provide cities with efficient and sustainable mobility solutions. The objective of this study is to understand the perceptions of URPT employees in relation to PII, based on a comprehensive case study. By exploring how these two concepts interrelate and influence each other, the study seeks to provide valuable information that can help improve strategic planning and policy formulation in the urban transport sector. The research, based on semi-structured interviews with 20 employees, reveals significant gaps in internal communication, with only about half of the participants aware of ongoing national and international projects. Information was often limited to those directly involved, indicating a need for improved dissemination strategies. Despite these communication issues, employees positively view the company’s presence at international events and recognize the importance of involvement in European organizations, particularly for knowledge acquisition and networking. Challenges identified include inadequate internal communication and insufficient investment in international projects. However, there was strong agreement on the value of internationalization and innovation process (IIP) for both professional development and organizational growth. To enhance the company’s international presence and return on investment (ROI), the study recommends better coordination, improved information sharing, and strategic planning. These findings emphasize the critical role of effective communication and active participation in international initiatives for the sustainable growth of the organization.

The Sustainable Development Goals (SDGs) can be viewed as the aftermath of the Millennial Development Goals (MDGs). This is due to the fact that the seventeen (17) SDGs are designed to continue the work expected to have been done by the MDGs. In other words, the failure of the MDGs to eradicate poverty birthed the SDGs. However, the SDGs seem not to be achieving the desired result. This has led to the projection for the need for a decade of action. In the African context, the questions of why the MDGs failed and the SDGs tend to be failing are yet to be asked. By projection, if the questions are not asked and answers are not provided, the projection of the decade of action may also fail. Hence, the reason for this conceptual paper which was targeted at exploring the possibility of considering the Africanization of the SDGs as remedy to ensuring sustainable development in the African continent. Different relevant sources were identified, reviewed and analysed. The findings from the reviewed and analysed sources showed among others that for Africanization of the SDGs to be a reality and practicable, glocalization must be embraced. Meanwhile, there will be need to question the use of Eurocentric curricula in African institutions of learning.
