Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Energy-optimal steering of transitions through a fractal basin boundary. [PDF]

open access: yes, 2004
We study fluctuational transitions in a discrete dy- namical system having two co-existing attractors in phase space, separated by a fractal basin boundary. It is shown that transitions occur via a unique ac- cessible point on the boundary.

Local and Tele‐Coupling Coordination Relationships Between Urban Resilience and Ecosystem Health in the Beijing‐Tianjin‐Hebei Region and Analysis of Their Influencing Factors

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Urban resilience and ecosystem health are essential foundations for regional sustainable development, yet their coupled and coordinated relationships remain insufficiently explored at the urban‐agglomeration scale. Taking the 13 prefecture‐level cities in the Beijing‐Tianjin‐Hebei urban agglomeration as the study area and using panel data for ...

A New Fractal Derivative and Its Integral Transform Methods for Economic Models

open access: yes
In this paper, we introduce the RLC-fractal derivative along with the fractal Laplace and fractal Sumudu transforms of it. Then we apply these transformations to solve economic models involving the RLC-fractal derivative.

Asymmetric Responses of Ecosystem Health to Urbanization in a Typical Karst City: Spatiotemporal Patterns and Driving Mechanisms in Guilin, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Urban expansion can substantially reshape ecosystem structure and functioning, especially in ecologically fragile Karst landscapes. Clarifying how ecosystem health (EH) responds to urbanization and identifying the factors that drive spatial variation in EH are important for regional sustainability.

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...

Linking Ecosystem Risk, Health, Services to Ecological Security Assessment in the Yellow River Basin: Spatiotemporal Dynamics and Nonlinear Driving Characteristics

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT A scientific assessment of ecological security (ES) and its nonlinear mechanism for key driving factors in the Yellow River Basin (YRB) is of great significance for ecological protection and sustainable development. This study proposes an ES assessment framework, which links ecosystem risk (ER), ecosystem health (EH), and ecosystem services ...

Ultrastable Water‐in‐Water Emulsions by Addition of Polyion Complex Micelles

open access: yesMacromolecular Rapid Communications, EarlyView.
Water‐in‐water emulsions from mixtures of dextran and poly(ethylene oxide) (PEO) prepared in the presence of polyion complex micelles display an increase of stability from few hours to several months. Both dextran‐in‐PEO and PEO‐in‐dextran were stable against coalescence over this period of time.

A Sequential One‐Pot Block Copolymer Synthesis: Toward Mesoporous Carbon Materials for Selective CO2 Adsorption

open access: yesMacromolecular Rapid Communications, EarlyView.
A sequential one‐pot photo‐iniferter RAFT method greatly simplifies the synthesis of PAN‐based block copolymers, offering quick access to hierarchically porous, N‐doped carbon membranes. This scalable and reliable process allows for easy fabrication of functional materials important for carbon capture applications.
