Methane hydrate (MH) has attracted considerable attention as a safe and efficient method for storing transporting natural gas. Its rapid formation high storage capacity are key factors in gas transportation technology. Given this background, study aimed to improve the kinetics of MH investigated synergistic effect carbon nanotubes (MCNTs) lecithin (PC) loofah supports promote MH. It was found that induction time shortened by 92.40 94.30% when concentration MCNTs dynamic system increased from 0.005 0.025 wt % compared pure water system, maximum could reach up 142.83 V/V, with 0.015 having greatest effect. On basis, static constructed coupling loofah, significantly accelerated 93.60%, 23.03% alone. Furthermore, introduction PC 50% promoted wall climbing growth MH, although impact on volume water-to-hydrate conversion rate smaller. Finally, based enhancement efficiency cost-effectiveness evaluation, we coupled MCNTs, PC, excellently economically green. This offers an efficient, economical, environmentally friendly new approach methane transport

Space–Time Dynamics of Mortality and Recruitment of Stems and Trees in a Seasonally Dry Tropical Forest: Effect of the 2012–2021 Droughts

Remote Sensing, Год журнала: 2025, Номер 17(9), С. 1491 - 1491

Опубликована: Апрель 23, 2025

Seasonally dry tropical forests (SDTFs) represent about 41.5% of the planet’s forests. The objective this study was to characterize annual mortality and recruitment patterns stems trees between years 2012–2021 in a Caatinga remnant state Pernambuco, Brazil, through geostatistical modeling, associate drought events recorded region with vegetation dynamics. Mortality were monitored 80 permanent plots located an SDTF remnant, counted year by 2012 2021. standardized precipitation index (SPI) calculated quantify deficit or excess rainfall evaluated period. data then subjected analysis based on calculation classical semivariances. As result, there loss 68.33% 61.93% forest community during 2012–2021, which associated water caused SPI for region. Gaussian semivariogram model better represented spatial variability trees. An accumulative effect droughts increasing rates reducing period observed. relationship tree stem highlights impact vegetation, emphasizing importance considering extreme climatic proper management natural resources.

Agricultural structure management based on water–energy–food and carbon sink scenarios in typical fuel ethanol raw material planting areas—a case study of the Hulan River Basin, Northeast China

Frontiers in Environmental Science, Год журнала: 2025, Номер 12

Опубликована: Янв. 30, 2025

The implementation of Chinese policies promoting fuel ethanol has significantly influenced the land use structure, water resources, and soil environment in raw material planting areas. This paper focuses on Hulan River Basin, a benchmark region for maize cultivation, to investigate specific crop allocation issues relation impact changes quality. study projects an environmentally economically sustainable structure cultivation materials using CLUE-S model multiple linear programming. Additionally, carbon sequestration potential is assessed under different scenarios. Throughout period, net ecosystem productivity (NEP) Basin demonstrated variability, evidenced by decrease 33.96 gC·m −2 ·a −1 from 2010 2015 subsequent augmentation 55.64 2020. Furthermore, three scenarios (Grain Crop Priority Policy, Fuel Ethanol Carbon Storage Policy) effectively addressed requirements use/cover types enhanced within area. Consequently, outcomes provide conceptual foundation regional policymakers, providing insights into refinement zones fostering advancement industry, thus undergirding prospective strategies water, energy, food, perspectives.
