Greenhouse gas cycling is an important component of earth system models that are used to project our future climate. Major physical, chemical and biological processes and controls of greenhouse gas cycling are often incorporated into biogeochemistry models of these gases. In particular, the hydrological cycle has long been linked to these models. However, more adequate hydrological models are s...

Defects are important features in two-dimensional (2D) materials that have a strong influence on their chemical and physical properties. Through the enhanced chemical reactivity at defect sites (point defects, line defects, etc.), one can selectively functionalize 2D materials via chemical reactions and thereby tune their physical properties. We demonstrate the selective atomic layer deposition...

Jean-Louis BIGOURDAN and James M. REILLY Image Permanence Institute Rochester Institute of Technology Rochester, New York, USA ABSTRACT The effect of changing environments on paper stability was studied using three types of paper (acid-processed 100% cotton, acid-processed groundwood, and buffered groundwood). The study was based upon three cycling situations. The effect of humidity cycling alo...

Point-of-care testing (POCT) of biomarkers in clinical samples is of great importance for rapid and cost-effective diagnosis. However, it is extremely challenging to develop an electrochemical POCT technique retaining both ultrasensitivity and simplicity. We report an interference-free electrochemical lateral-flow immunoassay that enables one-step ultrasensitive detection with serum. The electr...

the aim of this study was to evaluate the effect of cyclic loading on the bond strength of quartz fiber posts to root canal dentin after different surface treatments of different regions of root canal dentin.forty-eight single-rooted human teeth were selected. post spaces were prepared and then the teeth were divided into four groups: g1: no treatment (control); g2: irrigation with a chemical s...

Decomposition is a critical source of plant nutrients, and drives the largest flux of terrestrial C to the atmosphere. Decomposing soil organic matter typically contains litter from multiple plant species, yet we lack a mechanistic understanding of how species diversity influences decomposition processes. Here, we show that soil C and N cycling during decomposition are controlled by the composi...
