We show that a vanadium-chromium Prussian blue analogue, which is a room-temperature molecule-based magnet, displays a fast magnetic response on a femtosecond timescale that is attributed to the super-exchange interaction between the metal ions. These dynamics are obtained from femtosecond Faraday magneto-optical (MO) measurements, performed at 50 and 300 K. Exciting at the ligand-to-metal char...

Detailed understanding of the nature of the active centers in non-precious-metal-based electrocatalyst, and their role in oxygen reduction reaction (ORR) mechanistic pathways will have a profound effect on successful commercialization of emission-free energy devices such as fuel cells. Recently, using pyrolyzed model structures of iron porphyrins, we have demonstrated that a covalent integratio...

The two-echelon location routing problem (2E-LRP) arises in freight distribution when goods available at different origins are delivered to their respective destinations via intermediate facilities. literature concerning the 2E-LRP considers capacities of vehicles be scalars, while customer demands additive volumes individual items. However, ignoring real dimensions items and can lead infeasibl...

The mol-ecule of the title compound, C14H13N3O, adopts an E conformation with respect to the azomethine C=N bond, and is roughly planar, with an r.m.s. deviation of the non-H atoms from the least-squares plane of 0.100 (2) Å and a dihedral angle between the terminal benzene rings of 5.74 (12)°. An intramolecular N-H⋯N hydrogen bond closes an S(6) ring. In the crystal, mol-ecules are linked by t...

In the title compound, C(8)H(8)FN(3)O, the semicarbazide group is close to being planar, with a maximum deviation of 0.020 (1) Å, and subtends a dihedral angle of 16.63 (9)° with its attached fluoro-benzene ring. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming layers lying parallel to the bc plane.

Quenched autoligation (QUAL) probes are a class of self-reacting nucleic acid probes that give strong fluorescence signal in the presence of fully complementary RNAs and selectivity against single nucleotide differences in solution. Here, we describe experiments designed to test whether QUAL probes can discriminate between bacterial species by the detection of small differences in their 16S rRN...

Despite the need to better understand how customers of Software-as-a-Service (SaaS) solutions perceive the quality of these software services and how these perceptions influence SaaS adoption and use, there is no extant measure that comprehensively captures service quality evaluations in SaaS. Based on previous SERVQUAL and SaaS literature, field interviews and focus groups, a card-sorting exer...

Purpose: To synthesize Mannich base imidazole derivatives, and evaluate their antimicrobial, nematicidal and larvicidal properties . Methods: Compounds 1a-g and 2a-g were prepared using a Mannich condensation method. The chemical structures of compounds 2a-g were confirmed by Fourier transform infrared spectroscopy (IR), proton nuclear magnetic resonance (H-NMR), carbon nuclear magnetic resonan...
