Fluoropolymers are very important owing to their excellent application performances, especially in extreme conditions. On the other hand, preparation of porous fluoropolymers is a difficult task due unavailability suitable surfactants as well tedious synthesis steps. Here we prepared multifunctional fluoropolymer composite foams with simple process "high internal phase emulsion (HIPE)" by using humic acid modified iron oxide nanoparticles (HA-Fe3O4 NPs) and cationic fluorosurfactant (CFS)...
Phytohormones are key factors in plant responsiveness to abiotic and biotic stresses, maintaining hormone homeostasis is critically important during stress responses. Cut rose (Rosa hybrida) flowers experience dehydration postharvest handling, jasmonic acid (JA) levels change as a result of this stress. However, how JA involved tolerance remains unclear. We investigated the functions JA- dehydration-induced RhHB1 gene, which encodes homeodomain-leucine zipper I γ-clade transcription factor,...
Abstract Preparation of stable water‐in‐oil (W/O) high internal phase emulsion (HIPE) containing methyl methacrylate (MMA) monomer as oil is a difficult task due to the significant solubility MMA in water. Here, for first time fluorinated di‐block copolymer (FDBC) poly (2‐dimethylamino)ethylmethacrylate‐ b ‐poly (trifluoroethyl methacrylate) (PDMAEMA‐ ‐PTFEMA) proposed stabilize HIPEs without use any co‐stabilizer or thickening agent. Fluorinated segments FDBC anchored well at oil/water...
Titanium dioxide (TiO 2 ) and graphite (C g particles were co-deposited with nickel–phosphorous (Ni–P) coatings through electroless deposition process. Surface morphology of the was analysed by scanning electron microscope (SEM). X-ray diffraction (XRD) used to detect structure coatings. Microhardness Ni–P–C –TiO composite coating showed a moderate hardness between Ni–P–TiO coating. DSC thermograms indicated that thermostability Ni–P could not be affected TiO and/or C particles. Moreover,...
Efficient continuous-wave (CW) laser operation is demonstrated at room temperature with disordered Yb:Ca3(NbGa)2-xGa3O12 crystal by diode pumping 974 – 976 nm. With 2.0 W of pump power absorbed in a 1.5 mm thick crystal, CW output 0.62 generated, resulting an optical-to-optical efficiency 31%, while the slope amounts to 50%. Upon increasing high level, transient process takes place, which decreases continuously towards its stationary value.
Al doped ZnO (AZO) films were prepared on glass substrates by radio frequency (RF) magnetron sputtering technology.
