Complete classification of surfaces with a canonical principal direction in the Euclidean space \mathbb{E} 3

In the present paper we classify all surfaces in $ \mathbb{E} $ \mathbb{E} ³ with a canonical principal direction. Examples of this type of surfaces are constructed. We prove that the only minimal surface with a canonical principal direction in the Euclidean space $ \mathbb{E} $ \mathbb{E} ³ is the catenoid.

Magnetic Trajectories in an Almost Contact Metric Manifold $${\mathbb{R}^{2N+1}}$$

In this paper we classify magnetic trajectories γ in \({{\mathbb{R}}^{2N+1}}\) endowed with a canonical quasi-Sasakian structure, corresponding to a magnetic field proportional to the fundamental 2-form. We prove that they are helices of order 5 and we show that there exists a totally geodesic \({{\mathbb{R}}^5}\) in \({\mathbb{R}^{2N+1}}\) such that γ lies in \({{\mathbb{R}}^5}\). Moreover, the quasi-Sasakian structure of \({{\mathbb{R}}^5}\) is that induced from the ambient manifold.     

Direct electron transfer between heme-containing enzymes and electrodes as basis for third generation biosensors

Direct electron transfer (DET) between redox enzymes and electrodes found the basis for third generation biosensors. Recent investigations in the authors’ laboratories on the bioelectrochemistry of heme-containing proteins and enzymes, primarily peroxidases, but also cellobiose dehydrogenase, will be reviewed.
