The adsorption of sulfur and halogen containing materials on nickel studied by X-ray photoelectron spectroscopy and thermal desorption spectroscopy
… methyl bromide, methyl iodide, methyl sulfide, dimethyl sulfide, dimethyl disulfide, and bis(trifluoromethyl) disulfide on clean, polycrystalline nickel surface (at 25°C) were investigated using an X-ray photoelectron spectrometer (XPS) and a thermal desorption system with mass spectrometric …

In operando SEM for the accelerated exploration of nanomaterials and their scalable device integration
… remain: 1D silicon nanowires and 2D tungsten disulfide. For the former, in situ vacuum annealing is performed to visualise the growth dynamics of nickel-silicide phases into silicon nanowires (`silicidation'), a candidate method for establishing high-quality electrical contacts. However, …

Effect of shelf-life and light exposure on acetaldehyde concentration in milk packaged in HDPE and PETE bottles
… compounds studied (acetaldehyde, pentanal, dimethyl disulfide, and hexanal) were increased in light-exposed milk samples. Amber PETE showed the least amount of oxidation off-flavor, while clear PETE with UV block showed significantly less oxidation off-flavor than glass, clear PETE or HDPE …

Studies of Sulfur-based Cathode Materials for Rechargeable Lithium Batteries
… we use a small organotrisulfide compound, e.g. dimethyl trisulfide, to be a high capacity and high specific energy organosulfide cathode material for rechargeable lithium batteries. Based on XRD, XPS, SEM, and GC-MS analysis, we investigated the cell reaction mechanism. The redox reaction of …

Laboratory studies of atmospheric photochemistry in indoor and outdoor environments
… First, this thesis examines the oxidation of dimethyl sulfide (DMS), which represents a large natural source of sulfur to the atmosphere and affects the climate. Using varied chemical conditions across numerous environmental chamber experiments, we characterize aerosol formation from the …

Analysis of the volatile organic compounds produced by the decomposition of pig carcasses and human remains
… acid, octanal, indole, phenol, benzaldehyde, dimethyl disulfide and trisulfide, which represent potential target compounds of decomposition odour. Currently there is a demand for improved canine training aids and pig carcasses have been proposed as an alternative due to their acceptance as …

Sensorial characteristics of odour active compounds from raw natural rubber
… within rubber emissions were methyl mercaptan, dimethyl sulfide, dimethyl disulfide, and dimethyl trisulfide. Due to their low Odour Threshold Value (OTV), all identified VSCs potentially contribute to the overall sensorial profile of the rubber odour. While Volatile Organic Compounds (VOCs) …

Managing Weeds and Soilborne Pests with Fumigant and Non-Fumigant Alternatives to Methyl Bromide
… mulch, and grafting. Methyl iodide (MeI) and dimethyl disulfide (DMDS) were tested as fumigant alternatives to MBr for the control of yellow nutsedge and soilborne pathogens of tomato. Virtually impermeable film (VIF) and totally impermeable film (TIF) were tested for fumigant retention and …

Anticarcinogenic, Antitumor, and Antifungal Properties of Allium Sativum (Garlic)
… burst.</p> <p>The cytotoxic effects of diallyl disulfide (DADS, 5-200 /xg/ml), DAS (200 /ig/ml), dimethyl disulfide (DMDS, 5-400 /xg/ml) and allyl methyl sulfide (AMS, 5-400 /xg/ml), were determined with in vitro cultures of MBT-2, R3327, HL-60 and K562 tumor cells. DADS exhibited toxicity …

Very accurate gas-phase thermochemistry through photoelectron photoion coincidence (PEPICO) spectroscopy
… The last project involves measurements on dimethyl disulfide (DMDS) and dimethyl diselenide, which are the simplest models that can be used to study disulfide and diselenide linkages. There are several discrepancies in the thermochemistry of DMDS, whereas ours is the first experimental …

Exploring the Genomic, Plant Growth Promoting, and Biocontrol Potential of a novum species 'Candidatus Pseudomonas auctus' JDE115 with its description
… and volatile organic compounds (VOCs) such as dimethyl disulfide (DMDS) and 1-undecene. Greenhouse experiments confirmed that JDE115-treated soybean plants remained disease-free, while untreated controls succumbed to infection. Further evaluations demonstrated that JDE115 effectively suppresses …
