Government-level ESG (environmental, social, and governance) institutionalization and active ESG activation in the private sector are being discussed for the first time this year in Korea, spurred by increased national interest since the COVID-19 pandemic crisis and the declaration of a carbon-neutral society by 2050, and ESG discussion in many fields is spreading rapidly. In addition, global awareness of the crisis caused by environmental pollution and natural disasters has highlighted the importance of green infrastructure (GI) as a new conceptual alternative to improve public value. Based on sustainability, which is a common goal of ESG and green infrastructure, this study aimed to examine the research targets and techniques of green infrastructure from the perspective of ESG. This study selected and analyzed 98 domestic and international academic journal papers published over the past 10 years in the Web of Science academic journal database literature collection. Focusing on the research subjects, the focus on green infrastructure, and research keywords, we examined the aspects of the green infrastructure plan that have been focused on from the ESG perspective and compared domestic and international research trends. In addition, implications for how each research topic is connected to the concept of ESG according to its function and purpose were derived. By examining the domestic and international research trends of green infrastructure from the ESG perspective, we identified the need for a wider range of research on the diversity and relationship between humans and the ecological environment; policies and systems; and technical research that does not focus only on a specific field. In this regard, we intend to increase the contribution to ESG management in the public sector through the establishment of green infrastructure plans and policies in the future, as they account for a large portion of public capital.

Vacant land presents many challenges for older financially distressed cities. Community engagement is a very important element to solve the urban vacant land problem and assist in long term regeneration. This paper reviews what plans, policies, implementation methods, and community engagement process were developed to overcome barriers and challenges to vacant land projects. Most studies reveal that the importance of community engagement process in terms of understanding the problems and potential value of vacant land, redevelopment process, financial support, regulation, and neighborhood organizations participation for vacant land projects. To encourage community engagement to repurpose vacant land, municipalities should have to provide adequate information about vacant land conditions and their potentials in terms of ecological and social value. Code enforcement and tax foreclosure are efficient ways to control vacant land and the abandoned building problem. Tax incentive systems, such as high taxation rates on land but a low rate or no tax at all on infill development on vacant land, tax credits on vacant land forest structure, and rehabilitation abatement on abandoned buildings can increase public investment in vacant land. Local governments should support such efforts by creating community involvement groups, such as neighborhood coordinators, civic leaders, CDCs (Community Development Corporations), and other community-based nonprofit organizations. Community engagement is not specific planning, but it is part of an ongoing process in planning strategies to urban regeneration and renewal vacant land.

We report the exfoliation of layered Na2Ti3O7, a promising anode material for Na-ion batteries, and restacking using HNO3and NaOH to form H-[Ti3O7] and Na(x)-[Ti3O7] compositions, respectively. The materials were characterized by a range of techniques (SEM, TEM, solid-state NMR, XRD, PDF). Although the formation of aggregated nanoparticles is favored under acidic restacking conditions, the use of basic conditions can lead to control over the adherence between the exfoliated layers. Pair distribution function (PDF) analysis confirms that the local TiO6connectivity of the pristine material is maintained. The lowest sodium-containing phase Na(1)-[Ti3O7], which is the stable product upon Na+leaching after consecutive washing steps, displays the best performance among the compositions studied, affording a stable reversible capacity of about 200 mAh·g-1for 20 cycles at a C/20 rate. Washing removes the excess of "free/reactive" Na+, which otherwise forms inactive Na2CO3in the insufficiently washed compositions. ; M.A.T, A.J.P, J.M.S, and R.N.K. acknowledge funding from the United States Department of Energy (DOE, funder reference: 7057154).
