Soil moisture is a key factor in ecosystems that profoundly affects carbon, nitrogen, and water cycles on land surfaces, vegetation growth, and climate change. Consequently, numerous scholars have researched and authored scientific literature on soil moisture and related topics. Using the Web of Science database, we conducted a bibliometric analysis of 60,581 papers published in the field of soil moisture between 2000 and 2022. The findings revealed the following trends. (1) The number of publications on soil moisture has consistently increased in the 21st century at an increasing rate. For instance, although the annual increase was only 94 publications in 2005, it surged to 321 publications in 2020. (2) The United States (US), China, and developed European countries emerged as primary research institutions and authors. The US occupies a leading position in soil moisture research, boasting the highest number of publications and total citations in the field, whereas China ranks second in both publications and total citations. (3) Regarding international collaboration, the US has established close partnerships with numerous international research institutions. However, China’s international cooperation in this field requires improvement. (4) The Journal of Hydrology holds the top position in terms of both the total number of published articles and citations. Research on water resources ranked first in terms of its H-index. (5) Keyword analysis highlighted several current research hotspots, including the coupled covariance effect of soil moisture and land surface environmental factors in the context of climate change, soil moisture utilization rate, crop yield, influence mechanism of soil moisture on soil ecosystem structure, and development of high-precision soil moisture data products. In conclusion, this study provides a systematic review of the research hotspots and trends in soil moisture studies in the 21st century. The objective is to offer a comprehensive reference to aid in understanding the evolutionary patterns of soil moisture research in multiple dimensions.

“…This aromatic substance, with deep-rooted cultural, religious, and traditional medicinal value, has witnessed an unprecedented rise in demand across various industries, ranging from perfumery to pharmaceutic (Tan et al, 2019;Thuy et al, 2019a; Wang et al, 2022). As an academician deeply engaged in exploring emerging trends, this bibliometric analysis seeks to comprehensively examine the trajectory of Agarwood Aquilaria oil studies within the scholarly landscape (Burhanudin et al, 2022). Agarwood's historical importance is underscored by its use in diverse cultural practices and traditional healing systems (Aqmarina Nasution et al, 2020; Mahabob, Fawwaz Mohd Amidon, et al, 2022;Sun et al, 2020).…”

This bibliometric article investigates the burgeoning research landscape surrounding Agarwood oil, derived from the Aquilaria tree species. The historical and cultural significance of Agarwood, coupled with its diverse applications in perfumery, traditional medicine, and religious practices, has fueled a surge in scientific interest. However, a comprehensive understanding of the current state of Agarwood oil research is lacking. This study addresses this gap through a systematic review and bibliometric analysis of scholarly databases. By employing techniques such as co-citation analysis and keyword co-occurrence, the research aims to quantify patterns, relationships, and collaborations within the literature. The methodology involves a focused exploration of a specified timeframe to capture recent developments, with the anticipation that the outcomes will include the identification of key contributors, thematic clusters, and emerging trends in Agarwood oil research. The study is poised to contribute valuable insights for researchers, policymakers, and industry stakeholders, offering a holistic perspective on the interconnectedness of Agarwood oil research and guiding future exploration in this dynamic field.

“…There are a few types of disturbances that drive geomagnetic storms, such as coronal mass ejection (CME), corotating interaction regions (CIRs), and interplanetary shocks [2,3]. The geomagnetic field variations create surface geoelectric electric fields and cause low frequency (0.001-1 Hz) geomagnetically induced currents (GICs) flow into grounded technological conductors [4,5] such as oil and gas pipelines, power networks, and railway [6], as illustrated in Fig. 1 FIGURE 1.…”

With the global commitment to achieving net zero carbon emissions by 2050, the importance of transitioning to clean and efficient energy sources has become increasingly crucial. On this note, Grid resiliency is crucial for sustainable energy supply because it ensures a reliable and uninterrupted flow of electricity from renewable sources to consumers. By withstanding and recovering quickly from disruptions, the grid can maintain stable energy supply, support the integration of intermittent renewable sources, and meet the increasing demand for clean energy. This study presents the detail case study of the extreme geomagnetic disturbance (GMD) impacts on high voltage (HV) power networks in Peninsular Malaysia. The GMD events arise from extreme conditions on the Sun due to solar activity and drive geomagnetically induced current (GIC) in power transmission lines and other technological conductor networks, causing half-cycle saturation of earthed transformers and leading to voltage-control problems or transformer failure. The power system model comprises 54 substations interconnected with 500 kV, 275 kV, and 132 kV transmission lines. The GIC was calculated through the system with respect to different extreme geoelectric field strengths and substation grounding resistance (GR) values using the nodal admittance matrix (NAM) method. The results showed that extreme GMD events could produce severe GIC values across the system, especially at substations located at the edge and middle of the power network, meaning that the Malaysian power grid is not immune to such events. The maximum GIC was obtained at substation 22 with a value of 896 A at field orientation 140°. Also, the results showed that when the GRs of the substations were decreased, the calculated GICs across the system increased.
