TL;DR: Increasing pH apparently facilitated deprotonation of the acidic functional groups (-COOH, -OH) of CNTs, which promoted the pi-electron-donor ability of the graphene surface, therefore enhancing pi-pi electron- Donor-acceptor (EDA) interactions of the two nitroaromatics (pi-Electron acceptors).
Abstract: We systematically studied effects of pH, ionic strength, and presence of Cu2+ (50 mg/L) or a dissolved humic acid (HA, Fluka) (50 mg/L) on adsorption of three nonionic aromatic compounds, naphthalene, 1,3-dinitrobenzene, and 1,3,5-trinitrobenzene to single-walled carbon nanotubes. Presence of Cu2+ or variance in the ionic strength between 0.02 and 0.1 M (NaNO3) only slightly affected adsorption affinities. Presence of HA reduced adsorption of the three compounds by 29−57% for CNTs, as measured by change in distribution coefficient (Kd), and by 80−95% for graphite. In contrast to nonporous graphite, whose surface area was completely accessible in adsorption, CNTs formed aggregates with microporous interstices in aqueous solution, which blocked large HA molecules from competing with the surface area. Changing the pH from 2 to 11 did not affect adsorption of naphthalene, while it increased adsorption of 1,3-dinitrobenzene and 1,3,5-trinitrobenzene by 2−3 times. Increasing pH apparently facilitated deprotonat...

TL;DR: The Yellow River is noted for its small water discharge and huge sediment load, which amounts to about11 × 108 tons every year, contributing 17% of the world's fluvial sediment discharge to the ocean as mentioned in this paper.

TL;DR: Results not only pave the way for applications of Bi₅TiO₃-based piezoceramics, but also have great impact on the understanding of the mechanism of depolarization so as to provide a new design to optimize the performance of lead-free piezoelectrics.
Abstract: Piezoelectric materials are used as sensors or actuators in many devices. Here, the authors demonstrate that semiconducting ZnO particles embedded into a Bi0.5Na0.5TiO3-based matrix improve its piezoelectric properties, promising an alternative to presently used lead-based materials.

TL;DR: In this article, a hybrid inversion method was developed to estimate the LAI values of crops based on PROSAIL simulation datasets, 43 hyperspectral vegetation indices (VIs), including the optimized soil-adjusted vegetation index (OSVAI) and modified triangular vegetation index(MTVI2), were analyzed to identify optimal VIs for estimating LAI.

30 Jul 2005TL;DR: Experiments show that COREG can effectively exploit unlabeled data to improve regression estimates and is proposed as a co-training style semi-supervised regression algorithm.
Abstract: In many practical machine learning and data mining applications, unlabeled training examples are readily available but labeled ones are fairly expensive to obtain. Therefore, semi-supervised learning algorithms such as co-training have attracted much attention. Previous research mainly focuses on semi-supervised classification. In this paper, a co-training style semi-supervised regression algorithm, i.e. COREG, is proposed. This algorithm uses two k-nearest neighbor regressors with different distance metrics, each of which labels the unlabeled data for the other regressor where the labeling confidence is estimated through consulting the influence of the labeling of unlabeled examples on the labeled ones. Experiments show that COREG can effectively exploit unlabeled data to improve regression estimates.
