We investigated dibenzo[a,h]thianthrene molecules adsorbed on ultrathin layers of NaCl using a combined low-temperature scanning tunneling and atomic force microscope. Two stable configurations exist corresponding to different isomers free nonplanar molecules. By means excitations from inelastic electron we can switch between both configurations. Atomic microscopy with submolecular resolution allows unambiguous determination the molecular geometry, pathway interconversion isomers. Our...
Abstract Octahedral molecular sieves (OMS) are built of transition metal-oxygen octahedra that delimit sub-nanoscale cavities. Compared to other microporous solids, OMS exhibit larger versatility in properties, provided by various redox states and magnetic behaviors metals. Hence, offer opportunities electrochemical energy harnessing devices, including batteries, capacitors electrochromic systems, two conditions met: fast exchange ions the micropores stability upon exchange. Here we unveil a...
Two 2,6-bispyrazolylpyridine ligands (bpp) were functionalized with pyrene moieties through linkers of different lengths. In the ligand 2,6-di(1H-pyrazol-1-yl)-4-(pyren-1-yl)pyridine (L1) group is directly connected to bpp moiety via a C–C single bond, while in 4-(2,6-di(1H-pyrazol-1-yl)pyridin-4-yl)benzyl-4-(pyren-1-yl)butanoate (L2) it separated by benzyl ester involving flexible butanoic chain. Subsequent complexation Fe(II) salts revealed dramatic influence nature substitution on...
To evaluate, among alcohol specialists belonging to the Société Française d'Alcoologie (SFA), i.e., French Alcohol Society, proportion of physicians who prescribed off-label baclofen for use disorders (AUDs). The secondary objective was depict features individual prescribing and monitoring practices.On-line survey 484 specialists. Physicians were asked whether they AUDs. If did not, reasons this choice investigated. did, physician's practice explored, including number patients treated, mean...
The functionalisation of a Si(100) silicon wafer allows for the oriented grafting monolayer Mn12 nanomagnets using two-step procedure.
Abstract Superparamagnetic nanoparticles are promising objects for data storage or medical applications. In the smallest—and more attractive—systems, properties governed by magnetic anisotropy. Here we report a molecule-based synthetic strategy to enhance this anisotropy in sub-10-nm nanoparticles. It consists of fabrication composite materials where anisotropic molecular complexes coordinated surface Reacting 5 nm γ-Fe 2 O 3 with [Co II (TPMA)Cl ] complex (TPMA: tris(2-pyridylmethyl)amine)...
Two types of factors can theoretically modulate alcohol metabolism toward increased acetaldehyde production. These are the following: (a) individual, genetically determined isoenzymes with distinct catalytic properties, and (b) modifications enzyme activity induced by itself or liver damage. To investigate respective roles these in white individuals, we studied dehydrogenase phenotype, together aldehyde activities, 161 patients. Patients alcoholic cirrhosis (n = 31) were compared three...
Comparison of alcohol dehydrogenase polymorphism at the loci ADH 2 and 3 is made in France between 46 alcoholic cirrhotic patients 39 controls, by genotyping technique using polymerase chain reaction on blood microsample collected blotting paper. The genotype distributions are similar, with low frequency 22 allele. Polymorphism locus not a genetic factor for cirrhosis France.
Inducing chirality in semiconductor nanoparticles is a recent trend motivated by the possible applications circularly polarized light emission, spintronics, or stereoselective synthesis. However, previous reports on CdSe nanoplatelets (NPLs) exclusively rely cysteine its derivatives as chiral ligands to induce optical activity. Here, we show strong induction of with tartaric acid obtained single-step The ligand exchange procedure organic solvent was optimized for five-monolayer (5 ML) NPLs...
Organizing magnetic nanoparticles into long-range and dynamic assemblies would not only provide new insights physical phenomena but also open opportunities for a wide spectrum of applications. In particular, major challenge consists the development nanoparticle-based materials which remnant magnetization coercive field can be controlled at room temperature. Our approach promoting self-organization in liquid crystals (LCs). Using as organizing templates allows us to envision design tunable...
Nickel(II) β-azido-meso-tetraphenylporphyrin was successfully anchored on silicon using a bifunctional linker that bears two terminal alkyne functions by the sequence (i) hydrosilylation of CC triple bond surface Si–H groups and (ii) 1,3-Huisgen cycloaddition between alkyne-terminated azidoporphyrin derivative.
Aims: To estimate the prevalence of pathological gambling (pG) in people addicted to alcohol and drugs, particularly those with use disorders (AUDs), including new forms such as video on-line games; update socio-demographic profile suffering from both AUD pG. Method: A cross-sectional survey was conducted 1 week 2009 55 French addiction treatment centres, all consecutive patients attending that centre, using an anonymous questionnaire which included a tool specific for pG screening, DEBA-jeu...
This study aims to identify the prevalence and at-risk situations of alcohol use disorders among patients examined in emergency department compare scales commonly used disorders. We CAGE AUDIT questionnaires a structured interview, MINI. Of presenting patients, 9.5% met DSM-IV criteria for The questionnaire was less sensitive (75%) more specific (92%) than (87 80%, respectively). typical alcohol-dependent patient is young man who unemployed brought by police. During past 24 h, he has...
Recently, we reported on the bistable configurational switching of dibenzo[a,h]thianthrene (DBTH) molecules adsorbed NaCl using combined low‐temperature scanning tunneling and atomic force microscopy (STM/AFM). Here, discuss intra‐molecular contrast in AFM images as a function tip–molecule distance. Our experiments show that ridges frequency shift do not necessarily correlate with chemical bonds this case non‐planar molecule. To explain finding compare acquired at different distances to...
The grafting of a monolayer 6 nm superparamagnetic cyanide-bridged CsNiCr nanoparticles was achieved on Ni(II)-functionalized Si(100) substrate; magnetic studies reveals that the grafted are nearly magnetically isolated within monolayer.
Moderate alcohol consumption is associated with lower cardiovascular mortality. The effect of moderate intake during 5 weeks on lipoproteins, especially the high density lipoprotein (HDL) cholesterol total (of which levels are inversely predictive coronary heart disease) and apoproteins A, A1 B, was studied in 7 normal men. HDL appreciated by heparin manganese precipitation method phosphortungstate magnesium increased (p < 0.01) consumption. composition modified consumption: increase...
Controlling the elaboration of Coordination Networks (CoNet) on surfaces at nanoscale remains a challenge. One suitable technique is Sequential Growth in Solution (SGS), which has advantage to be simple, cheap and fast. We addressed two issues this article: i) controlled synthesis ultra thin films CoNet (thickness lower than 10 nm), ii) investigation influence precursors' concentration growth process. Si(100) was used because it possible prepare atomically flat Si-H surfaces, necessary for...
