Scientists have successfully created a novel class of metal nitrides made from noble metals, exhibiting unusual or unique properties. These new compounds may prove to be even more durable than current titanium nitrides used in the semiconductor industry.
Catalytic converters in US vehicles emit toxic pollutants when they fail, putting public health at risk. Researchers detected these pollutants using advanced analytical techniques.
Researchers found a single layer of water on a platinum surface is hydrophobic, repelling subsequent layers, contrary to previous assumptions about water molecule attachment points. The discovery challenges current theories and has implications for technological applications such as catalysis and corrosion.
Student researcher Christopher Kovalchick used a low-cost technique to test tiny samples of four metal alloys and found that combining platinum with chromium resulted in the greatest strength. The findings are important because pure platinum is too soft for use in durable jewelry, but adding chromium improves its mechanical properties.
Researchers at Ames Laboratory have developed a new thermal barrier coating technology that enhances engine operation in high-temperature environments. The new coating, which uses nickel-aluminum-platinum alloy samples, offers significant improvements in oxidation resistance and reduces the risk of failure in gas turbines.
Researchers at Emory University have successfully created a unique metallic molecule, breaking the record for stable metal-oxo species. The breakthrough enables new insights into improving existing technology, particularly in automobile catalytic converters and fuel cells.
The Cornell Institute for Fuel Cell Development aims to create more efficient and affordable fuel cells by discovering new materials, potentially using alternative fuels like methanol and ethanol. Researchers hope to find compounds that can overcome the limitations of current fuel cell technology.
Researchers have developed a new catalyst that can produce hydrogen at lower temperatures and with reduced greenhouse gas emissions compared to traditional methods. The catalyst, based on nickel, tin, and aluminum, has the potential to be used in industrial applications such as fertilizers production and petroleum products processing.
A study of 800 women with relapsing ovarian cancer found that combination chemotherapy showed a modest survival benefit compared to platinum-based chemotherapy alone. Women assigned combination therapy survived for an average of five months more than those given platinum therapy.
Scientists at Fritz-Haber Institute find mechanical oscillations in catalytic foil during chemical reactions, leading to precise measurement of heat created. Mathematical models and computer simulations reveal delicate interplay between thermo-chemistry and thermo-mechanics.
BioNumerik reports success with its engineered cancer agents, demonstrating reduced toxicity while preserving antitumor activity. The company plans to initiate Phase 3 trials for BNP7787 and expand clinical trials for Karenitecin BNP1350.
BioNumerik Pharmaceuticals has discovered a new non-toxic platinum protecting agent, BNP7787, which substantially reduces the toxicity of platinum-type anticancer drugs. Preclinical studies show that BNP7787 increases cisplatin's antitumor activity while protecting against kidney toxicity, vomiting, and bone marrow toxicities.
