Examining Urban Impervious Surface Distribution and Its Dynamic Change in Hangzhou Metropolis

Remote Sensing, 2016
Analysis of urban distribution and its expansion using remote sensing data has received increasing attention in the past three decades, but little research has examined spatial patterns of urban distribution and expansion with buffer zones in different ...

Improving uncertainty in forest carbon accounting for REDD+ mitigation efforts

Environmental Research Letters, 2020
Reductions in atmospheric concentrations of greenhouse gases are urgently needed to avoid the most catastrophic consequences of warming. Reducing deforestation and forest degradation presents a climate change mitigation opportunity critical to meeting ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Coniferous-to-broadleaved forest conversion in subtropical coastal sandy lands enhances soil component respiration: coupled driving effects and mechanisms for improved carbon sequestration stability

Frontiers in Plant Science
IntroductionConiferous_to_broadleaved forest conversion reshapes soil carbon cycling in coastal sandy ecosystems, yet its regulation on component soil respiration and thermal sensitivity remains poorly quantified.

Urbanization and fragmentation mediate temperate forest carbon cycle response to climate

Environmental Research Letters, 2020
Forest fragmentation is ubiquitous across urban and rural areas. While there is mounting evidence that forest fragmentation alters the terrestrial carbon cycle, the extent to which differences in ambient growing conditions between urban and rural ...

Microbial drought resistance is achieved at the expense of soil carbon loss

Nature Communications
Life history strategies of soil microbiomes may determine their environmental adaptability and influence soil carbon-climate feedbacks. Here, we investigate trade-offs among microbial high yield (Y), resource acquisition (A), and stress tolerance (S ...

Mixed Plantations Mitigate Negative Effects of Natural Forest Conversion on Soil Meso- and Micro-Faunal Communities in Zhangguangcailing Mountains, Northeast China

Biology
Soil meso- and micro-fauna are key components of forest soil ecosystems, but the effects of converting natural forests to monoculture or mixed plantations on their communities remain unclear.

Unexpectedly efficient ion desorption of graphene-based materials

Nature Communications, 2022
Desorption of ions from sorbents generally involves high acid or base concentrations and long desorption times, especially for multivalent ions. Here the authors report a rapid and efficient desorption of Co2+, Mn2+, and Sr2+ adsorbed on magnetite ...
