Abstract The nutritional quality of acid‐modified poultry manure biochar is unclear, so a better understanding its properties and agronomic potential needed. was modified with phosphoric acid (H 3 PO 4 ) nitric ( HNO combination the two, before after pyrolysis. After characterization samples determination total water‐soluble mineral element concentrations, biochars were applied to calcareous soil at rate 0.5% (w/w) find out their effects on nutrition growth maize. Treatment H + enriches...
Phosphorus (P) is one of the least available mineral nutrients to plants in calcareous and alkaline soils. In this study, we investigated synthesis, characterization use synthetic nano-hydroxyapatite (NHA), P uptake by as well its residual effects. Soluble source (H3PO4) was also included treatment for comparison. NHA prepared wet chemical techniques, characterized Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) elemental dispersive X-ray (EDX) analysis....
A sensitive and economical analytical method involving the solidification of floating organic drop microextraction technique with a dispersive solvent is utilized for extraction enrichment nickel in St. John's wort tea infusions. Bis-N,N′-(salicylidene)-1,3-propanediamine was used as complexing agent. The analyses were done slotted quartz tube-flame atomic absorption spectrometer (FAAS). experimental parameters preconcentration procedure optimized. developed provided 26.5-fold enhanced...
Abstract Giant barocaloric effects were recently reported for spin-crossover materials. The volume change in these materials suggests that the transition can be influenced by uniaxial stress, and give rise to giant elastocaloric properties. However, no measurements of properties compounds have been so far. Here, we demonstrated existence associated with transition. We dissolved particles ([Fe(L) 2 ](BF 4 ) , [L=2,6di(pyrazol-1-yl)pyridine]) into a polymeric matrix. showed application tensile...
Abstract Six species of lichens, such as Usnea florida, barbata, longissima, rigida, hirta and subflorida, were collected from different areas Anatolia (district Antalya, Karabük, Çankırı, Giresun Trabzon) in Turkey. Their usnic acid amounts acetone extracts determined by HPLC. In addition, antimicrobial activities these against Escherichia coli (ATCC 35218), Enterococcus faecalis (RSKK 508), Proteus mirabilis (Pasteur Ens. 235), Staphylococcus aureus, Bacillus subtilis megaterium. It was...
Spin crossover (SCO) complexes have been shown to exhibit giant mechanocaloric effects. Due the change of magnetization at spin transition, they are also expected show magnetocaloric However, experimental studies on properties in SCOs scarce. Here, we studied response SCO complex [Fe(L)2](BF4)2, [L = 2,6-di(pyrazol-1-yl)pyridine] using pulsed magnetic fields. We that applying a field can induce partial transformation from low high state. directly measure adiabatic temperature for different...
Pseudevernia furfuracea (L.) Zopf biosorption efficiency for zinc(II) was determined. The of Zn(II) onto P. significantly affected by the parameters pH, biomass concentration, stirring speed, contact time, and temperature. maximum 92% at 10 mg/L Zn(II), 5 g/L lichen dosage. ions better described Langmuir model pseudo-second-order kinetic. obtained thermodynamic from were feasible, exothermic, spontaneous. different desorbents used to perform desorption studies Zn(II)-loaded biomass.

Abstract In this study, poly(vinyl alcohol) were cross-linked with boron in varying concentrations and blend fibers obtained diameters ranging from 0.3 μ to 4.0 μm the use of electrospinning process. The resulting product was characterized by SEM, DSC, FT-IR techniques. There is no beading tendency either doped or undoped fibers. When amount boric acid PVA solutions increased conductivity polymer decreased. data indicated existence oxide polymeric structure formation B-O-C bond. SEM...
