An In Situ Oxidation Strategy for Ti3C2@TiO2 Heterojunction: Narrow‐Band Photodetection and Trace Chromium Ion Determination

open access: yesAdvanced Functional Materials, EarlyView.
A Ti3C2@TiO2 heterostructure has been successfully fabricated by an in situ oxidation approach. The as‐fabricated Ti3C2@TiO2‐based photodetector exhibits narrow‐spectrum response with excellent stability. It also realizes sensitive Cr(VI) detection in a large concentration range of 10−12–10−6 M with an ultra‐low detection limit of 7.6 × 10−12 M ...

Statistics in soil science

open access: yes, 2005
Key points • Soil varies from place to place; statistics is a technology for describing that variation quantitatively and separating signal from noise. • Replicate sampling is required to estimate the variation in experimental material and geographic regions. • Randomization is needed to estimate mean values and their variances, and to place confidence

Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal

open access: yesAdvanced Functional Materials, EarlyView.
Using depth‐resolved, field‐ and pressure‐dependent μSR$\umu{\rm SR}$ measurements, we show that disorder in Ta‐doped KV3Sb5 drives a crossover from nodal to nodeless superconductivity while strongly modifying the normal‐state magnetic response. Our results reveal that disorder affects superconductivity and magnetism in fundamentally different ways ...

Remote sensing is a viable tool for mapping soil salinity in agricultural lands

open access: yesCalifornia Agriculture, 2017
Soil salinity negatively impacts the productivity and profitability of western San Joaquin Valley (WSJV) farmland. Many factors, including drought, climate change, reduced water allocations, and land-use changes could worsen salinity conditions there ...
