Elektrokemi är ett område där kemiska reaktioner sker genom ett utbyte av elektroner. Vissa elektrokemiska reaktioner sker naturligt medan andra kan drivas genom att ström förs genom systemet. Ett elektrokemiskt system består av elektroder som är de ytor där elektroner lämnas eller hämtas. Elektroderna är sedan placerade i en gas eller vätska som för elektronerna mellan dem. Elektrokemiska reaktioThere is a great interest in studying detailed changes at electrode surfaces during electrochemical processes to better understand the electrochemical reactions at the electrode surface-liquid interface and improve the electrode efficiency. The Au(110) surface has a known (1$\times$2) missing row reconstruction in vacuum conditions, which can change into higher-order (1$\times$3), (1$\times$5), an

Cyclometalated ruthenium(II) complexes, [Ru II(C~N)(N~N) 2]PF 6 [HC~N=2-phenylpyridine (Hphpy) or 2-(4'-tolyl)pyridine; N~N=2,2'-bipyridine, 1,10-phenanthroline, or 4,4'-dimethyl-2,2'-bipyridine], are rapidly oxidized by H 2O 2 catalyzed by plant peroxidases to the corresponding Ru III species. The commercial isoenzyme C of horseradish peroxidase (HRP-C) and two recently purified peroxidases from

An overview of the new field of Gas in Scattering Media Absorption Spectroscopy (GASMAS) is presented. The technique investigates sharp gas spectral signatures, typically 10000 times sharper than those of the host material, in which the gas is trapped in pores or cavities. The presence of pores causes strong multiple scattering. GASMAS combines narrow-band diode-laser spectroscopy, developed for a

Popular Abstract in Swedish Kemi finns överallt omkring oss, både i vår omgivning såväl som inuti oss. Vi kanske inte alltid tänker på det, men kemiska processer påverkar oss dagligen och är en förutsättning för vår existens. Det kanske därför inte är så konstigt att människan alltid varit intresserad och fascinerad av just kemi. Ämnet kemi används dock inte bara för att förstå kemiska processer iA considerable part of all chemistry in nature and in industry occurs in solvents. Sol- vents affect both the interactions and the reactions of the particles immersed in them. The work in this thesis concerns the properties of ionic and polar solvents, as well as the interactions between solutes and/or dispersed particles. Molecular simulations and simple approximate theories were used to study th

The use of radio-labeled somatostatin analogs, such as 177Lu-labelled DOTATATE, in PRRT, has based on the studies performed until now, shown to be promising for RNT disseminated neuroendocrine tumors [1]. In this regard, the aim of treatment is to assure the delivery of the highest possible absorbed dose to the tumor cells, while saving the normal tissues [1], meaning, to achieve a higher activity

The growing importance of achieving high productivity in the manufacturing industry leads to the necessity for applying high machining parameters and cutting speeds. However, the presence of self-excited vibrations of the tool shaft and workpiece under these conditions would result in undesirable surface roughness and surface integrity of the product. Thus, it is vital to study the damping mechani

House dust mites are animals of a size less than 0.5 mm that can live in beds, carpets and furniture feeding on skin scales. They are a common source of allergy in, e.g., Scandinavia, where their major habitat is in beds. Previous studies show that in drier environments the house dust mite occurrence is lower, and persons with dust mite allergy have fewer symptoms during the winter when the indoor

Due to the COVID-19 outbreak, industries have gained a thrust on contactless processing for computing technologies and industrial automation. Cloud of Things (CoT) is one of the emerging computing technologies for such applications. CoT combines the most emerging cloud computing and the Internet of Things. The development in industrial automation made them highly interdependent because the cloud c
