The infrared spectra of the formate, acetate, and oxalate ions have been obtained for both solid aqueous solution. Raman these with depolarization ratios in Vibrational assignments made which differ slightly acetate ion more markedly from earlier work. confirm Fonteyne’s assignment formate ion.
Molecular Fe azaphthalocyanine catalysts with diverse long-chain “dancing patterns” demonstrate variable oxygen reduction reaction performance for fuel cells, aligning well our pH-field coupled microkinetic model.
Zn–air batteries have only been used in limited applications, such as hearing aid batteries, due to their low power density and standard voltage of around 1.4 V. Therefore, use a drive source cutting-edge devices drones, it is essential improve the output density. Here, we propose with high potential (∼2.25 V) (∼318 mW/cm2) by using newly designed iron azaphthalocyanine unimolecular layer (AZUL) electrocatalyst tandem battery cell. The AZUL this new type cell had electrochemical stability...
In this report, we demonstrate that high-capacity hybrid supercapacitors can be realized by utilizing iron azaphthalocyanine (FeAzPc-4N) adsorbed activated carbons (ACs) as an electrode due to the combination of electric double layer carbon surfaces and redox reactions FeAzPc-4N molecules. By increasing mixing ratio with ACs, a maximum capacity 907 F/gAC is achieved, also enabling rapid charging discharging at 20 A/g. The revelation capacitor electrode's durability through 000 cycles...
This study describes the formation of macro-scale defects honeycomb-patterned polymer film and we discovered two types new line which differ from reported in past studies. We examined mechanisms clarified "Divergent" mode "Convergent" caused by "tectonics" water droplet arrays on solutions. The regions causing are made clear phase diagram represented radius density micro-scale droplets. In addition, results our calculations it possible to theoretically predict growth time for droplets grow...
The oxygen reduction reaction (ORR) at the cathode is one of critical bottlenecks in energy conversion process polymer electrolyte fuel cells (PEFCs) and metal–air batteries. An iron azaphthalocyanine unimolecular layer (Fe-AZUL) adsorbed onto a carbon substrate exhibited high ORR activity as an alternative Pt supported on black (Pt/C) electrocatalyst. We herein report synthesis various AzPc molecules with different peripheral structures complex metals, well measurements activities catalysts...

Abstract In this report, we elucidated the hydrogen evolution reaction (HER) catalytic activity of different metal-azaphthalocyanine unimolecular layer (AZUL) catalysts and compared overpotentials in alkaline electrolyte membrane water electrolysis (AEMWE). While are bit higher to Pt/C, system utilizing FeAzPc-4N with Sustainion ® showed a low overpotential 2.02 V at 1.0 A/cm 2 faraday efficiency 96.3% even among previous alternative catalysts. It is noteworthy that AZUL not using precious...
Background Small cell carcinoma of the endometrium is extremely rare. Aim We reported three cases this rare tumor and reviewed literature. Cases Case 1 was a 54-year-old woman case 3 58-year-old woman. Both patients presented with vaginal bleeding. 2, 53-year-old woman, had no symptoms vaginal-cervical smear suspicious for malignancy. All underwent surgery their tumors originated in endometrium. In all cases, pathological examination revealed small endometrium, immunohistochemical reactivity...
