Bio-inspired synthesis of N-doped TiO/C nanocrystals using jellyfish mucus with high visible-light photocatalytic efficiency.

Non-metal doping of titanium dioxide (TiO) has been widely investigated, because it can facilely improve the optical response of TiO under visible light excitation in environmental pollution treatments. In the ongoing efforts, however, little consideration has been given to the use of harmful marine organisms as dopants. Here, we employed the natural mucus proteins of the large harmful jellyfish and , which have frequently bloomed in East Asian marginal seas in recent decades, to synthesize mesoporous nitrogen-doped TiO nanocrystals modified with carbon (N-TiO/C) by a simple hydrothermal method.

[Application of high-speed counter current chromatography in extraction and separation of alkaloids in natural products].

Alkaloids, widespread in plants, have a series of pharmacological activities and have been widely used to treat various diseases. Because alkaloids are usually presented in multicomponent mixtures and are deeply low in content, they are very difficult to extract and separate by traditional methods. High-speed counter current chromatography(HSCCC) is a kind of liquid-liquid chromatography without solid support phase, which has the advantages of large injection volume, low cost, and no irreversible adsorption.

The pressure sensor was fabricated to work under low voltage conditions by using a high mobility amorphous indium-gallium-zinc oxide (a-IGZO) thin-film transistor (TFT) and a stretched polyvinylidene fluoride (PVDF) film. To prepare a stable sensor suitable for practical use, we designed a device structure that shields ambient noise by grounding the control gate.

Ionic liquid-based liposome for selective SERS detection.

An ionic liquid (IL)-based liposome was utilized as a substrate to construct a SERS platform. The isotropy of the IL outer surface together with its ion-exchange property led to the array-like growth of Au nanoparticles (NPs), generating hot-spots and resulting in anionic probes being present on the hot-spot regions. The simultaneous strategy of enrichment and localization endowed the platform with ability to detect trace amounts of anionic probes.

Different reaction models were constructed to fit the adsorption kinetics and adsorption isotherms of DCFP on GO, in order to further explore the underlying adsorption mechanism.

Synthesis of a 2D Cu@TiO composite the design of a 1D Cu-based coordination polymer precursor for efficient and selective photodegradation of dyes.

A 2D Cu@TiO composite with a porous and crystalline structure was successfully synthesized one-step and low-temperature calcination of a 1D Cu-based coordination polymer (Cu-CP), namely [Cu(3-dpha)(1,4-NDC)(HO)] (3-dpha = ,'-bis(3-pyridyl)adipamide and 1,4-HNDC = 1,4-naphthalenedicarboxylic acid). Moreover, the Cu@TiO membrane was fabricated by a simple filtration of the as-grown Cu@TiO composite. Compared with the benchmark TiO photocatalyst, the Cu@TiO composite material with high specific surface area and reduced photogenerated electron-hole ratio exhibited good photodegradation activity and durability for gentian violet (GV), which could be attributed to the combined effect of co-doping of Cu and TiO structure.

A P/N type silicon semiconductor loaded with silver nanoparticles used as a SERS substrate to selectively drive the coupling reaction induced by surface plasmons.

Semiconductor materials are favoured in the field of photocatalysis due to their unique optoelectronic properties. When a semiconductor is excited by external energy, electrons will transition through the band gap, providing electrons or holes for the reaction. This is similar to the chemical enhancement mode of a catalytic reaction initiated by the rough noble metal on the surface excited by plasmon resonance.

The obtained polymers were characterized and evaluated by FT-IR, H NMR, DSC and TGA. PAE-azo-CoPc exhibited higher glass transition temperature and better thermal stability than PAE-azo-DCN because of the introduction of cobalt phthalocyanine groups.
