Effect of Different Doping Concentrations on the Properties of Fe:ZnSe and Fe, Cr:ZnSe Crystals Grown by the Chemical Vapor Transport Method.

The Fe:ZnSe crystal is an important material for 3-5 μm mid-infrared lasers. In this work, we have grown different doping concentrations of Fe:ZnSe and Fe, Cr:ZnSe by the chemical vapor transport method. The doped crystals have the same structure.

Crystal Growth, Characterization, and Properties of Nonlinear Optical Crystals of LiAgGaSe for Mid-Infrared Applications.

LiAgGaSe is a new series of solid solution crystals that has a large nonlinear optical (NLO) coefficient and laser-induced damage threshold (LIDT). It has great application prospects in mid-infrared laser frequency conversion. In this work, LiAgGaSe ( = 0, 0.

Na-Ions Diffusion Impacts Supercapacitor Performance for Amaryllis-like NiCoO Nanostructures.

NiCoO nanomaterials with exceptional electrochemical performances are synthesized via a simple and low-cost method. The synthesized nanostructures exhibit a high specific surface area of 121.52 m g and excellent specific capacitance of 2498.

Rapid Immobilization of Simulated Radioactive Soil Waste Using Self-Propagating Synthesized Gd₂Ti₂O₇ Pyrochlore Matrix.

A rapid and effective method is necessary in the disposal of severely radioactive contaminated soil waste. Simulated Ce-bearing radioactive soil waste was immobilized by self-propagating high-temperature synthesis (SHS) within 5 min in this study. The main work includes the rapid synthesis of soil waste forms, the analysis of phase composition, microstructure and chemical durability.

Evaluation on the stabilization of Zn/Ni/Cu in spinel forms: Low-cost red mud as an effective precursor.

Red mud, which is from the aluminum industry, is a potentially under-utilized resource. Technological processes for using low-cost red mud as an alternative precursor for detoxifying metal pollutants urgently need to be developed. In this study, we systematically investigated the feasibility of using red mud to detoxify metal-containing wastes (e.

Self-Propagating Synthesis and Characterization Studies of Gd-Bearing Hf-Zirconolite Ceramic Waste Forms.

Synroc is recognized as the second-generation waste matrice for nuclear waste disposal. Zirconolite is one of the most durable Synroc minerals. In this study, Gd and Hf were selected as the surrogates of trivalent and tetravalent actinide nuclides.

Heavy-ion irradiation effects on UO incorporated GdZrO waste forms.

In this research, the heavy-ion irradiation effects of U-bearing GdZrO ceramics were explored for nuclear waste immobilization. UO was designed to be incorporated into GdZrO from two different routes in the form of (GdU)(ZrU)O (x = 0.1, 0.

One-pot sonochemical synthesis of magnetite@reduced graphene oxide nanocomposite for high performance Li ion storage.

In this research, we introduce a one-pot sonochemical method for the fabrication of magnetite@reduced graphene oxide (FeO@rGO) nanocomposite as anode material for Li-ion batteries. FeO@rGO is synthesized under ultrasonic irradiations by using iron (II) salt and GO as raw materials. An in-situ oxidation-reduction occurs between GO and Fe during the ultrasonic chemical reaction process.

Growth mechanism of one-step self-masking reactive-ion-etching (RIE) broadband antireflective and superhydrophilic structures induced by metal nanodots on fused silica.

This work presents a low-cost, simple, convenient, advanced technology to prepare large-area defect-free subwavelength structures (SWSs). SWSs were obtained by a metal-induced one-step self-masking RIE process on a fused-silica surface, in which metal-fluoride (mainly ferrous-fluoride) nanodots were used to induce and gather stable fluorocarbon polymer etching inhibitors in the RIE polymers as masks. The SWS growth processes are visible with an increase in etching time and some exhibit prominent broadband antireflective properties from the visible to the near-infrared wavelength range.

[The longitude study on the mental development of congenital hearing-impaired infants and toddlers].

Objective: To explore the effect of chronological age and acoustic device in cognitive development of congenital hearing-impaired infants and toddlers, and analyze the correlation of abilities in cognitive development with other factors.

Methods: Depending on chronological age (1 year old group and 2 years old group) and acoustic device (hearing aids and cochlear implantation), locomotor, personal-social, hearing and speech, hand and eye co-ordination, performance tests in Griffith Cognitive Development Scale were used to assess the cognitive development of 80 hearing-impaired infants and toddlers aged 0-2 years, including before intervention (0 month), after intervention (6, 12 months). Datas were analyzed by Repeated Measurements and Pearson Correlation Test.
