Improving the radiance retrieval accuracy in limb sounding by utilizing a similarity model correcting the internal thermal radiation for an infrared radiometer.

For commercially available infrared radiometers with a small volume and a light weight and without an independent cooling system for the optical structure, thermal sensitivity is a key constraint for their application to high-precision limb observations. In this research, the response law of a medium wave (3.7-4.

Interaction of composite fume suppression and odor elimination agents with crumb rubber modified asphalt: Inhibition behavior of volatile organic compounds (VOCs) and inorganic fume.

The production and construction of crumb rubber modified asphalt (RMA) at high temperatures can produce a large amount of toxic fume, which is detrimental to human health and environment. In this study, a series of composite fume suppression and odor elimination agents (CSEAs) with both physical adsorption and chemical capture functions were adopted to reduce the emissions of volatile organic compounds (VOCs) and hydrogen sulfide (HS). The material composition, microstructure, and specific surface area of CSEA were analyzed by using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and N adsorption-desorption isotherm (BET).

Diversity of Fungal Endophytes in American Ginseng Seeds.

Seeds play a critical role in the production of American ginseng. Seeds are also one of the most important media for the long-distant dissemination and the crucial way for pathogen survival. Figuring out the pathogens carried by seeds is the basis for effective management of seedborne diseases.

Engineering Unique Ball-In-Ball Structured (NiCo)S@C Nanospheres for Advanced Sodium Storage.

Constructing hollow architectures based on metal sulfides is of great interest for high-performance electrode materials for sodium-ion batteries because of their intriguing properties and various applications. However, the relatively low volumetric density and high fragile structure are the obstacles blocking the development of hollow-structured electrode materials. In this work, ball-in-ball structured (NiCo)S@C nanospheres have been synthesized by using NiCo-glycerate as the precursor via solvothermal reaction, which was followed by a carbon coating treatment.

SnS@C Hollow Nanospheres with Robust Structural Stability as High-Performance Anodes for Sodium Ion Batteries.

Constructing unique and highly stable structures with plenty of electroactive sites in sodium storage materials is a key factor for achieving improved electrochemical properties through favorable sodium ion diffusion kinetics. An SnS@carbon hollow nanospheres (SnS@C) has been designed and fabricated via a facile solvothermal route, followed by an annealing treatment. The SnS@C hybrid possesses an ideal hollow structure, rich active sites, a large electrode/electrolyte interface, a shortened ion transport pathway, and, importantly, a buffer space for volume change, generated from the repeated insertion/extraction of sodium ions.

Electrochemical sensor based on a three dimensional nanostructured MoS nanosphere-PANI/reduced graphene oxide composite for simultaneous detection of ascorbic acid, dopamine, and uric acid.

A three dimensional (3D) nanostructured composite based on the self-assembly of MoS nanospheres and polyaniline (PANI) loaded on reduced graphene oxide (denoted by 3D MoS-PANI/rGO) was prepared a feasible one-pot hydrothermal process. The 3D MoS-PANI/rGO nanocomposite not only exhibits good functionality and bioaffinity but also displays high electrochemical catalytic activity. As such, the developed 3D MoS-PANI/rGO nanocomposite can be employed as the sensing platform for simultaneously detecting small biomolecules, , ascorbic acid (AA), dopamine (DA), and uric acid (UA).

Heterophase-structured nanocrystals as superior supports for Ru-based catalysts in selective hydrogenation of benzene.

ZrO heterophase structure nanocrystals (HSNCs) were synthesized with tunable ratios of monoclinic ZrO (m-ZrO) to tetragonal ZrO (t-ZrO). The phase mole ratio of m-ZrO versus t-ZrO in ZrO HSNCs was tuned from 40% to 100%. The concentration of the surface hydroxyl groups on m-ZrO is higher than that on t-ZrO.
