Responses of Soil Microbial Community to Rocky Desertification Succession and Their Relationships With Plant Functional Diversity in Southwest China Karst Ecosystem

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
During the succession of karst rocky desertification, soil bacterial diversity was directly influenced by both plant functional diversity and soil physicochemical properties. In contrast, soil fungal diversity was directly regulated by soil physicochemical properties and indirectly affected by plant functional diversity via the mediation of soil ...

Low-Energy Electron Potentiometry: Contactless Imaging of Charge Transport on the Nanoscale

open access: yesScientific Reports, 2015
Charge transport measurements form an essential tool in condensed matter physics. The usual approach is to contact a sample by two or four probes, measure the resistance and derive the resistivity, assuming homogeneity within the sample.

Potassium-based algorithm allows correction for the hematocrit bias in quantitative analysis of caffeine and its major metabolite in dried blood spots [PDF]

open access: yes, 2014
Although dried blood spot (DBS) sampling is increasingly receiving interest as a potential alternative to traditional blood sampling, the impact of hematocrit (Hct) on DBS results is limiting its final breakthrough in routine bioanalysis.

Concentration-dependent mobility in organic field-effect transistors probed by infrared spectromicroscopy of the charge density profile

open access: yes, 2007
We show that infrared imaging of the charge density profile in organic field-effect transistors (FETs) can probe transport characteristics which are difficult to access by conventional contact-based measurements.
