A Review of Macrocycles Applied in Electrochemical Energy Storge and Conversion.

Macrocycles composed of diverse aromatic or nonaromatic structures, such as cyclodextrins (CDs), calixarenes (CAs), cucurbiturils (CBs), and pillararenes (PAs), have garnered significant attention due to their inherent advantages of possessing cavity structures, unique functional groups, and facile modification. Due to these distinctive features enabling them to facilitate ion insertion and extraction, form crosslinked porous structures, offer multiple redox-active sites, and engage in host-guest interactions, macrocycles have made huge contributions to electrochemical energy storage and conversion (EES/EEC). Here, we have summarized the recent advancements and challenges in the utilization of CDs, CAs, CBs, and PAs as well as other novel macrocycles applied in EES/EEC devices.

Key Role Effect of Samarium in Realizing Zero Thermal Quenching and Achieving a Moisture-Resistant Reddish-Orange Emission in BaLaNbO:Sm.

The strategy to enhance phosphor stability against thermal quenching and moisture conditions will contribute to controlling the feature of phosphor-converted white-light-emitting diodes (pc-WLEDs). Herein, an effective strategy is achieved with the incorporation of Sm ions, and a robust reddish-orange emission (no thermal quenching up to 498 K) is obtained based on BaLaNbO as a host. In light of excitation by near-ultraviolet irradiation at 408 nm, BaLaNbO:Sm gives rise to a typical signal ascribed to the G → H ( = 5, 7, 9, and 11) transitions of Sm ions.

A New Co-Substitution Strategy as a Model to Study a Rare-Earth-Free Spinel-Type Phosphor with Red Emissions and Its Application in Light-Emitting Diodes.

The substitution of metal sites in MgTiO substrate leads to charge imbalance that will be closely related to a variety of changes including lattice structure, cell distortion, and photophysical properties. Herein, the co-substitution strategy of [Ga-Ga] for [Mg-Ti] and Sn for Ti achieves for the first time the novel MgGaSnO (MGS):Mn ( = 0-3%) phosphors with efficient red emissions. In terms of X-ray powder diffraction (XRD) and Rietveld refinement analysis, MGS:Mn possesses a structure isotypic of MgTiO in the cubic space group 3̅ (227).

Interpenetrated Binary Supramolecular Nanofibers for Sensitive Fluorescence Detection of Six Classes of Explosives.

In this work, we develop a sequential self-assembly approach to fabricate interpenetrated binary supramolecular nanofibers consisting of carbazole oligomer 1-cobalt(II) (1-Co) coordination nanofibers and oligomer 2 nanofibers for the sensitive detection of six classes of explosives. When exposed to peroxide explosives (e.g.

Discrimination of Five Classes of Explosives by a Fluorescence Array Sensor Composed of Two Tricarbazole-Nanostructures.

In this work, we report a two-member fluorescence array sensor for the effective discrimination of five classes of explosives. This smallest array sensor is composed of tricarbazole-based nanofibers (sensor member 1) and nanoribbons (sensor member 2) deposited as two film bands in a quartz tube. On the basis of a simple comparison of the resulting fluorescence quenching ratios between two sensor members and the response reversibility upon exposure to vaporized explosives, five classes of explosives can be sensitively detected and easily discriminated.

[Bacterial 16S rRNA genes and expression of IL-1β, TNF-α and IgA in prostate tissues].

Objective: To investigate the role of bacteria in the etiology of chronic prostatitis.

Methods: Complete prostate specimens were obtained at autopsy from 192 organ donors (aged 20 - 38 years old) during 2002 to 2008 who died of non-prostatic diseases. One tissue taken from the peripheral prostatic zone according to McNeal was divided into two pieces.

[Expressions of bacterial 16S rRNA, IL-1beta, TNF-alpha and NGF in prostate tissues].

Objective: To investigate the role of bacteria in the etiology of chronic prostatitis.

Methods: A total of 162 complete prostate specimens were obtained at autopsy from organ donors (aged 20 -38 yr) who died of non-prostatic diseases. Each of the samples from the peripheral zone of the prostate was divided into two parts, one for routine pathological examination and immunohistochemical studies of interleukin (IL)-1beta, tumor necrosis factor-alpha (TNF-alpha) and the nerve growth factor (NGF), and the other for PCR assay to detect the bacterial 16S rRNA gene (16S rDNA).

[Endothelin-1 expression and quantitative analysis in astrocytomas].

Background & Objective: It is demonstrated that endothelin-1 (ET-1) is synthesized by and released from certain malignant tumor cells, and it plays an important role in growth and development of tumor. This study was designed to investigate the expression of ET-1 in astrocytomas and the relationship between the ET-1 quantity and the grades of astrocytomas.

Method: ET-1 expression was determined in 70 astrocytoma specimens using Streptavidin-Peroxidase method and image analysis technology.
