On the shores of Lake Turkana in east Africa, about 5,000 to 4,000 years ago, pastoralists buried their dead in communal cemeteries that were marked by stone circles and pillars. The north-west Kenya "pillar sites" were built ...
Conventional techniques of generating alkylbenzene, a key input in the production of detergents, produce toxic halogen byproducts, but researchers have devised a new technique that offers a more efficient, cheaper and cleaner ...
Organic N-alkyl amines are important chemical products and intermediate with wide applications in the fields of daily chemicals, pesticides, pharmaceuticals, surfactants, and life sciences. The C–N bonds formed by alkylating ...
RUDN University agronomists have shown that the hormone melatonin and the mineral zeolite mitigate the dangerous effects of heavy metals on plants. The first protects cells from destruction by cadmium, and the second increases ...
Non-precious metal catalysts (NPMC) have strong potential in energy conversion devices due to their excellent oxygen reduction reaction (ORR) performance in fuel cells. Since in most NPMC materials, the accessible active ...
According to a new paper, ancient Maya reservoirs, which used aquatic plants to filter and clean the water, "can serve as archetypes for natural, sustainable water systems to address future water needs."
A centuries-old technique for constructing arched stone windows has inspired a new way to form tailored nanoscale windows in porous functional materials called metal-organic frameworks (MOFs).
The fuels used today depend heavily on petroleum. As the demand grows, scientists are looking for ways to produce fuels that do not require petroleum. A research team set out to examine the role of zeolites in the conversion ...
A molecular switch, or molecule that changes in response to varying environmental stimuli, has successfully modified the acidity of a zeolite catalyst to improve the yield of paraxylene from methanol in heterogeneous catalysis, ...
Metal-organic frameworks (MOFs) are a class of materials that contain nano-sized pores. These pores give MOFs record-breaking internal surface areas, which make them extremely versatile for a number of applications: separating ...
