Graphene-based nanomaterial system: a boon in the era of smart nanocarriers
Jha Roopali,Singh Amit,Sharma Pramod Kumar,Porwal Omji,Fuloria Neeraj Kumar 한국약제학회 2021 Journal of Pharmaceutical Investigation Vol.51 No.3
Background Owing to its exceptional electronic, mechanical, thermal, as well as optoelectronic characteristics, graphene—a planar sheet with one-atom thickness and made of carbon atoms closely packed in quite a honeycomb crystal lattice—has already earned special consideration. The investigated characteristics or even applications of such a two-dimensional configuration of the structure of carbon have already created novel innovative opportunities in place of all of the future devices as well as nanosystems. Area covered These graphene systems have also been recognized as a potential drug-delivery carrier intended for target specific or even controlled drug delivery, which could be designed by utilizing various internal or external stimuli. Expert opinion This review predominantly focuses on graphene’s synthesis and derivative, design of stimuli-responsive nanosystems, and applications in various fields. It is highlighted that with remarkable progress in graphene-related research, graphene’s overall execution has a long road ahead to go.

Operational performance model for Indian container terminals using qualitative comparative analysis
Nanyam V.P.S. Nihar,Jha Kumar Neeraj 한국해운물류학회 2022 The Asian journal of shipping and Logistics Vol.38 No.4
Trend forecasting shows that Indian container terminals will handle 25 million twenty-foot equivalent units (TEUs) by 2025. However, improving operational performance is the best strategy to achieve this target. Many factors have adversely affected the Indian container terminal's operational performance despite the fact that the Indian government has undertaken several initiatives. This study identifies factors and interactive effects of the factors influencing the operational performance of Indian container terminals. A conceptual model is developed using fuzzy qualitative comparative analysis (QCA) encompassing the successful factors. The conceptual model developed through QCA includes the physical characteristics, driving factors, and challenges. This study reveals the combined and individual effects of the identified factors. The results show that the most common factors are the quay infrastructure, yard infrastructure, infrastructure up-gradation, system initiatives, reefer systems, and logistics advantage. This study adds to the existing literature regarding the Indian container terminals' performance and supports the decisionmakers in improving the operational performance of container terminals. © 2022 The Authors.

Critical Factors Affecting No-dispute Performance: A Case of Ethiopian Public Construction Projects
Sinesilassie, Ephrem Girma,Tabish, Syed Zafar Shahid,Jha, Kumar Neeraj Korea Institute of Construction Engineering and Ma 2016 Journal of construction engineering and project ma Vol.6 No.4
Disputes seem to be synonymous with large-scale construction projects in Ethiopia. The purpose of this study is to determine the factors responsible for impacting the performance of Ethiopian public construction projects. To this end, 35 success and failure attributes responsible for impacting the performance of the projects were identified and presented to Ethiopian construction professionals in the form of a structured questionnaire, and responses were collected. The factor analysis conducted on the success and failure attributes influencing no-dispute performance separately resulted in six success factors and five failure factors. Further analysis using stepwise multiple regression indicates that owner competence and interaction among project participants have a positive impact on no-dispute performance. However, conflict among project participants has a negative impact on the no-dispute performance of Ethiopian public construction projects. Although Ethiopia-specific, the results reflect construction management problems common to both developed and developing countries. The findings are expected to help researchers and practitioners gain a better understanding of critical success and failure factors and to help them take proactive measures to avoid disputes in public construction projects.

Modeling challenges affecting the performance of major ports of India
Nanyam V.P.S. Nihar,Kumar Jha Neeraj 한국해운물류학회 2023 The Asian journal of shipping and Logistics Vol.39 No.3
Despite several initiatives taken by government of India since 2013 to improve the performance of major ports, growth was not as anticipated. Hence, there is a need to understand the performance of these major ports during 2013–2020 and to identify the critical challenges that affect their performance. Design/methodology/approach: Performance analysis was conducted using Malmquist productivity index (MPI) and critical challenges were identified using interpretive structural modelling (ISM) technique as well as the cross-impact matrix multiplication (MICMAC). Findings: Ten major ports in terms of operational, 12 ports in terms of service quality, and six ports in terms of financial performance have been categorised as high performers, based on the MPI values. 19 challenges affecting the performance were identified in an eight layered ISM model. Research limitations: This research is limited to major ports of India and does not cover the non-major ports of India due to unavailability of data Practical implications: This study will enable the port decision-makers to identify the ports which are high performers in terms of operational, service quality, and financial performance, and thereby the best practices followed across can be replicated. Originality/value: This study explored the multi dimensions of performance of Major ports of India and there was no such study in the past. Despite the existence of performance studies in the literature, none of them explored the challenges faced by the major ports
