نانوخوشه های دوفلزی به دلیل مفید بودنشان در کاتالیست ها وحسگرها مورد توجه هستند. شبیه سازی¬های دینامیک ملکولی با استفاده از پتانسیل کوانتوم ساتن-چن برای مطالعه ساختاری، رفتار ذوب، انرژی سطح و ضریب خودنفوذی نانوکلاستر طلا-مس در ترکیبهای مختلف از طلا-مس با 55 اتم انجام شد. محاسبات نشان می¬دهد که انرژی سطح در نانوکلاستر طلا- مس با کسر مولی اتم های مس افزایش و با دما کاهش می¬یابد. برای نانو کلاستره...

It has been well established that nitrogen coordinated transition metal, TM-N4-C (TM = Fe and Co) moieties, are responsible for the higher catalytic activity electrochemical oxygen reduction reaction. However, results obtained using density functional theory calculations vary from one to another, which can lead controversy. Herein, we assess accuracy of theoretical approach different class exch...

A basic result in graph theory says that any n-vertex tournament with in- and out-degrees larger than n−24 contains a Hamilton cycle, this is tight. In 1990, Bollobás Häggkvist significantly extended by showing for fixed k ε>0, sufficiently large n, all tournaments degrees at least n4+εn contain the k-th power of cycle. Up until now, there has not been progress on determining more accurate erro...

We present a detailed analysis of the genome architecture, structural proteome and infection-related properties of three Pseudomonas phages, designated LUZ7, LIT1 and PEV2. These podoviruses encapsulate 72.5 to 74.9 kb genomes and lyse their host after 25 min aerobic infection. PEV2 can successfully infect under anaerobic conditions, but its latent period is tripled, the lysis proceeds far slow...

Here N2 is the number of triangles in the simplicial manifold consisting of N4 four-simplices and the topology is chosen to be that of S. (For more details see [1].) We recall that the system has two phases, a crumpled phase at low 2 and an elongated phase at high 2. The model is supposed to represent the quantum gravitational path integral over euclidean spacetimes weighted with the Regge-Eins...

Introduction: Children are one of the most vulnerable groups to sub-optimal nutritional intake in most societies. We have investigated some of the potential determinants of malnutrition in children of 2-5 years of age.   Methods and Materials: A cross sectional study was conducted to determine the relationship between nutritional status (weight for age, height for age and weight for height) and...

A cyclometalated complex of Ir(III) is covalently tethered to DNA oligonucleotides and serves as both a photooxidant and photoreductant in the study of DNA-mediated hole transport (HT) and electron transport (ET). Spectroscopic and melting temperature studies support intercalation of the tethered complex into the DNA duplex through the functionalized dppz ligand. Using these tethered assemblies...
