Abstract Mineral preservation and microbial residue production are vital for the accumulation of mineral‐associated organic carbon (MAOC) in soils. However, their relative importance interactive effects remain unclear. Here MAOC content composition analyzed tandem with soil mineral attributes along a weathering gradient on volcanic sequence. We find that increases increasing states, accompanied by contribution to MAOC. rather than physiological traits strongly related contents, suggesting...
Abstract Metal‐bound organic carbon (OC) is vital for the persistence of soil (SOC). However, its relative importance in different land types (e.g., upland vs. wetland) remains unclear. Here by analyzing metal‐bound OC classic citrate‐bicarbonate‐dithionite method (OC CBD ) from 62 soils contrasting environments, we find that constitutes an equally important proportion SOC %) wetlands as uplands. Land‐use type and calcium (Ca) content are best predictors %, likely owing to contribution...
Toxic gas monitoring at room temperature (RT) is of great concern to public health and safety, where ultrathin silicon nanowires (SiNWs), with diameter <80 nm, are ideal one-dimensional candidates achieve high-performance field-effect sensing. However, a precise integration the tiny SiNWs as active sensor channels has not been possible except for use expensive inefficient electron beam lithography etching. In this work, we demonstrate an integratable fabrication sensors based on orderly SiNW...

Abstract While lignin geochemistry has been extensively investigated in the Amazon River, little is known about distribution and dynamics within deep, stratified river channels or its transformations soils prior to delivery rivers. We characterized phenols soils, particulate organic matter (POM), dissolved (DOM) across a 4 km elevation gradient Madre de Dios River system, Peru, as well marine sediments investigate source‐to‐sink evolution of lignin. In we found more oxidized horizons...
Quasi-1D silicon nanowires (SiNWs) field effect transistors (FETs) integrated upon large-area elastomers are advantageous candidates for developing various high-performance stretchable electronics and displays. In this work, it is demonstrated that an orderly array of slim SiNW channels, with a diameter <80 nm, can be precisely grown into desired locations via in-plane solid-liquid-solid (IPSLS) mechanism, reliably batch-transferred onto large area polydimethylsiloxane (PDMS) elastomers....
Abstract Mineral binding of organic carbon (OC) is one the key mechanisms promoting soil (SOC) persistence, which vital for long‐term sequestration atmospheric dioxide into soils. However, relative importance two main types minerals ‐ metal oxides and silicate clay—in SOC protection remains unclear, hampering our ability to predict protect this important pool persistent SOC. Here, we analyzed OC bound (OC ) versus clay in soils from contrasting environments (i.e., wetlands uplands) using...
Abstract Flexible near‐infrared (NIR) photodetectors (PDs) are desired for accurate heart rate monitoring, based directly on arterial‐blood‐volume‐change detection, instead of indirect oximetry technology. In this work, a robust 3D construction flexible a‐SiGe:H p ‐ i n radial junction (RJ) PDs is explored upon soft Al foils, working at NIR wavelength 800 nm, which has the highest skin transparency and least absorption difference from oxyhemoglobin deoxyhemoglobin variation. The RJ‐PDs...

Abstract. Respiration and leaching are two main processes responsible for soil carbon loss. While the former has received considerable research attention, studies examining limited, especially in semiarid grasslands due to low precipitation. Climate change may increase extreme precipitation event (EPE) frequency arid regions, potentially enhancing loss through respiration. Here we incubated columns of three typical grassland soils from Inner Mongolia Qinghai–Tibetan Plateau examined effect...
Abstract Chinese grasslands hold a third of the national soil organic carbon (OC) stocks but remain poorly investigated in terms molecular components and their distribution patterns. Such information is important for understanding mechanisms governing grassland OC dynamics its response to global changes. Here employing solvent‐extractable compounds as group widely used biomarkers, we present large‐scale study on different (including plant‐ microbial‐derived carbohydrates aliphatic cyclic...
