A sudden nov...

The effect of the hyaluronic acid (HA) on the state and photoactivity of the cationic phthalocyanine photosensitizer in mixed solutions was studied by UV–vis absorption, fluorescence, FT-IR spectroscopy and dynamic light scattering methods. As a cationic photosensitizer, the Cholosens® (ChS) was...

High-efficiency interfacial separation of photoexcited electron-hole pairs and wide spectral response are the two major factors for photocatalytic performance improvement in a bismuth oxyhalide-based system. This research displayed a facile method to prepare an iron phthalocyanine/bismuth oxybro...

The interaction between tin phthalocyanine (SnPc) and polycrystalline iron has been studied with XPS and synchrotron radiation excited XPS. After incremental annealing of a thin film of SnPc on a polycrystalline iron substrate, a low binding energy component of the Sn 3d core level became increa...

Wide wavelength inverted organic solar cells (IOSCs) were fabricated and characterized by doping the active layer with long wavelength absorbing tin (II) phthalocyanine (SnPc). The hole-transporting layer (HTL) comprised Ag nanoparticles (NPs)-embedded poly(3,4-ethylene dioxythiophene):poly(styr...

Here, we demonstrate a facile strategy to enhance the efficiency and stability of perovskite solar cells (PKSCs) by modification the perovskite with a simple small molecule SnPc layer. A maximum PCE of 16.52% has been achieved in the modified PKSCs and it increases by 25% in compared with the pr...

The performance of organic solar cells (OSC) based on tin (II) phthalocyanine (SnPc)/C60 heterojunction was investigated by changing the thickness of SnPc. The effect of the film thickness of SnPc on the electrical characteristics of the device was systematically studies. Optical field distribut...

The electrosynthesis of ammonia from nitrogen and water is a topic of considerable interest in the quest for sustainable and decentralized NH3 production. Tin(II) phthalocyanine complexes have been proposed as electrocatalysts for nitrogen reduction to ammonia in aqueous solution, with Faradaic ...

The present study aimed to demonstrate the role of mepiquat chloride (MC) on the alleviation of the damaging effects of salinity on the germination of four cotton cultivars. Based on the ecophysiological data, CCRI44, CCRI49, and Z571 were less sensitive to salt stress and relied on a salt toler...

The growth regulator mepiquat chloride (MC) is globally used in cotton (Gossypium hirsutum L.) canopy manipulation to avoid excess growth and yield loss. However, little information is available as to whether the modification of plant architecture by MC is related to alterations in gibberellic a...

Our aim was to study the adsorption of the plant regulator mepiquat to montmorillonite and test the suitability of montmorilonite–mepiquat complexes in formulations to reduce leaching of the non-polar herbicide, acetochlor. Adsorption of the monovalent organic cation mepiquat to montmorillonite...

A simple, accurate and highly sensitive analytical method was developed in this study for determining the residues and dissipation dynamics of mepiquat chloride in soil and cotton crops (including plant and seed). The samples in this method were directly extracted with methanol–ammonium acetate...

Late planting of short-season cotton under high plant density and single fertilization after rapeseed harvest is a promising alternative to traditional relay intercropping of full-season cotton in the Yangtze River Valley of China. However, it is not clear if mepiquat chloride (MC) application i...

Incredible accomplishments have been achieved in agricultural production in China, but many demanding challenges for ensuring sustainable cotton production remain. An efficient cropping model characterized with late sowing, higher density and low fertilizer application is a promising alternative...

Mepiquat (N,N-dimethylpiperidinium) is a plant growth regulator registered for use as its chloride salt in many countries on cereals and other crops. Recent model system studies have shown that natural chemicals present in crop plants, such as pipecolic acid and pipecolic acid betaine, may furni...

Cotton production is challenged by high cost with multiple management and material inputs including mepiquat chloride (MC) application to avoid excess vegetative growth and yield losses. A competitive planting model has been practiced in recent years in Yangtze River Valley, China characterized ...

Lodging is a major adversity which limits maize grain yields and quality, especially under dense population. The present study was conducted to determine the efficacy of mepiquat chloride, a potential anti-gibberellic plant growth retardant on plant height, the physical strength of stem, lignin ...

Redox initiated free-radical polymerization of methyl methacrylate (MMA) with allyl alcohol 1,2-butoxylate-block-ethoxylate (AABE) was carried out using cerium(IV) ammonium nitrate/nitric acid (HNO3) redox system to yield AABE-b-PMMA copolymers.
