The rapid recombination of photoinduced electron-holes and the low utilization of solar energy have become two disadvantages limiting the performance of current photocatalysts. In this work, a novel composite photocatalyst, in which the carbon quantum dots (CQDs) were supported on the NH2-MIL-12...

A sandwich-type amperometric immunosensor based on pH responsive sensitivity amplifiable route was elaborately designed for determination of carcinoma antigen 125 (CA 125). The sensitivity of amperometric immunosensor depends on a change of current response (ΔI) attributed to antigen to be test...

A novel, simple, sensitive, and precise spectrofluorometric assay of cancer antigen [CA 125] is described. This modality is based on monitoring the quenching of the luminescence intensity at 790 nm of the phthalocyanine fluorophore, in a nanocomposite comprising the fluorophore and cationic poly...

Sensitive and specific bioassays of tumor markers are critical for early cancer detection and treatment. In recent years, lanthanide (Ln3+) doped upconversion nanoparticles (UCNPs) have attracted wide attentions in tumor markers detection. Herein, we combined NaYF4:Yb,Tm and silver nanoparticles...

Controllable and efficient photo-catalyst is of particular importance not only for improving photo-catalytic activity of hydrogen evolution, but also for achieving more excellent performance of semiconductors in practical applications. Here two n-type semiconductors (cobalt phosphide (CoP) and M...

Metal nanoparticles (NPs) decorated MOFs for photocatalysis has drawn enormous attention in the past decade. Here, a series of M/Ti-MOFs (M = Pt and Au, Ti-MOFs = MIL-125-NH2 and MIL-125) has been synthesized through a facile post-synthetic method and the metal NPs highly dispersed on surface of...

Exploration of solid-state efficient red emissive carbon dots (CDs) phosphors is strongly desired for the development of high performance CDs-based white light-emitting diodes (WLEDs). In this work, enhanced red emissive CDs-based phosphors with photoluminescence quantum yields (PLQYs) of 25% we...

The rising levels of carbon dioxide in the atmosphere are responsible for fundamental changes occurring in seawater carbonate chemistry. The partial pressure of oceanic CO2 (pCO2) is one of the four measurable parameters defining the marine carbon system. For this reason, the pressing need of as...

Organic pigment permanent red F2R nanoparticles were prepared via surface modification to improve the surface charge and dispersion ability in organic medium.Their large surface chargeability is confirmed by ζ-potential value of −49.8 mV. The prepared particles exhibited average size of 105 nm ...

The dispersion phenomena in aquifers through experimental activities have been extensively studied in the past; recently the availability of digital images of the transport process made possible the development of new techniques for the evaluation of the dispersivity coefficients (Sànchez et al...

This work was part of an investigation aimed at characterizing the molecular and excited state properties of currently available disperse dyes developed to provide stability to extensive sunlight exposures when adsorbed on poly(ethylene terephthalate) (PET) fibers. Having completed the character...

The traces of hazardous chemicals used in oil spill response have harmed marine creatures with long-term cytoxic impacts, so, a greener alternative is to use biodegradable components in the dispersant formulation. This study demonstrates the efficiency of carboxymethylated and acylated chitosan ...

We report an ingenious strategy for fabrication of hollow orange fluorescent carbon nanoparticles (HFCNs) and demonstrate their applications for pH biosensing and fingerprint detection. HFCNs have been synthesized using 5-amino salicylic acid as carbon source via one-step hydrothermal treatment ...

The Fe–Ca catalysts in catalytic pyrolysis of brown coals were studied to investigate the catalytic activity of the Fe–Ca in a fixed-bed reactor. Experimental results showed the maximum yields of the light aromatic hydrocarbons (LAHs) were 5.90 wt% (0.88 wt% of benzene, toluene and xylene ‘BT...

The seminal discovery of browning of white adipose tissue (WAT) holds great promise for the treatment of obesity and metabolic syndrome. DJ-1 is evolutionarily conserved across species, and mutations in DJ-1 have been identified in Parkinson's disease. Higher levels of DJ-1 are associated w...

Highly dispersible, uniform size (∼7 nm) single-phase Cu2ZnSnS4 nanoparticles have been synthesized by hydrothermal method using non-toxic surfactant (oleic acid). High resolution transmission electron microscopy image indicates good crystallinity of the Cu2ZnSnS4 nanoparticles with the growth ...
