The first complete genome sequence of Clostridium sporogenes DSM 795(T), a nontoxigenic surrogate for Clostridium botulinum, was determined in a single contig using the PacBio single-molecule real-time technology. The genome (4,142,990 bp; G+C content, 27.98%) included 86 sets of >1,000-bp identical sequence pairs and 380 tandem repeats.

Um composto de fórmula [ttf] 2 [Cu(opba)]·H 2 O, com ttf = tetrathiafulvaleno e opba = orto-fenilenobis(oxamato), foi preparado e caracterizado. O complexo foi obtido por reação de metátese entre (ttf) 3 (BF 4 ) 2 e (Bu 4 N) 2 [Cu(opba)] em acetonitrila à temperatura ambiente. O espectro UV-Vis-NIR mostra a presença do radical cátion em duas formas, (ttf ) e dímero (ttf ) 2 . As propriedades de...

The reactivity of the PGeP germylene 2,2’-bis(di-isopropylphosphanylmethyl)-5,5’-dimethyldipyrromethane-1,1’-diylgermanium(II), Ge(pyrmPiPr2)2CMe2, with late first-row transition metal (Fe-Zn) dichlorides has been investigated. All reactions led to pincer chloridogermyl complexes. FeCl2 and CoCl2 afforded paramagnetic square planar complexes formula [MCl{?3P,Ge,P-GeCl(pyrmPiPr2)2CMe2}] (M=Fe, C...

In industrial applications, most materials are exposed to wear and friction because multiple conditions are used. However, the tribological properties of these materials can be improved with different techniques. One such technique that improves the frictional property of a surface is the use of self-lubricating coatings. In this study, multicomponent coatings of nominal composition Cu-Ni3Al-Mo...

Abstract The development of a low temperature (−160 °C) NO adsorption technique is disclosed that avoids the chemical conversion probe molecule at room temperature. observed IR peaks for Cu + (NO) 2 and 2+ species can be used to quantify amount exchanged copper in broad range samples, including wash‐coated honeycomb. Calibration curves are determined loadings up 3.99 wt% with Silica‐to‐Alumina ...

We have investigated the spin-wave spectrum of copper metaborate, CuB 2 O 4 , by means of inelastic neutron scattering in the commensurate magnetic phase. We have found two branches of spin-wave excitations associated with the two magnetic sublattices Cu(A) and Cu(B), respectively. In the temperature regime 10K ≤ T ≤ 21K, where only the Cu(A) magnetic moments are ordered, the interaction betwee...

In this paper, the molecular dynamics (MD) method was used to study influence of factors bulk Cu material, such as effect number atoms (N) at temperature (T), T = 300 K, T, and annealing time (t) with Cu5324 on structure properties, phase transition, glass Tg material. The obtained results showed that transition (Tg) material 652 K; length link for Cu-Cu had a negligible change; r 2.475 Å; four...

There is an intricate interaction between iron (Fe) and copper (Cu) physiology in diatoms. However, strategies to cope with low Cu are largely unknown. This study unveils the comprehensive restructuring of the photosynthetic apparatus in the diatom Thalassiosira oceanica (CCMP1003) in response to low Cu, at the physiological and proteomic level. The restructuring results in a shift from light h...
