Há 9 horas · Tellurium is a chemical element; it has symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in its native form as elemental crystals. Tellurium is far more common in the Universe as a whole ...
Há 9 horas · The isotopes of titanium range in atomic weight from 39.002 u (39 Ti) to 63.999 u (64 Ti). The primary decay mode for isotopes lighter than 46 Ti is positron emission (with the exception of 44 Ti which undergoes electron capture ), leading to isotopes of scandium , and the primary mode for isotopes heavier than 50 Ti is beta emission , leading to isotopes of vanadium .
Há 1 dia · Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment, and jewelry. Palladium is a key component of fuel cells, in which hydrogen and oxygen react to produce electricity, heat, and water. Ore deposits of palladium and other PGMs are rare.
Há 9 horas · Eosinophils are myeloid effector cells whose main homing is the gastrointestinal tract. There, they take part in type I and type II immune responses. They also contribute to other non-immunological homeostatic functions like mucus production, tissue regeneration, and angiogenesis. In colorectal cancer (CRC), eosinophils locate in the center of the tumor and in the front of invasion and play an ...
Há 9 horas · The materials used in our study include beech ( Fagus orientalis ), lauric acid (LA) and borax (BX). Beech wood samples were selected from timber boards with a density of 0.66 g/cm3. The samples were cut entirely from the sapwood area and were used for burning experiments with dimensions of 5 (R) × 10 (T) × 100 (L) mm 3.
Há 9 horas · The following review focuses on the manufacturing and parameterizing of ocular drug delivery systems (DDS) using polymeric materials to create soft contact lenses. It discusses the types of drugs embedded into contact lenses, the various polymeric materials used in their production, methods for assessing the mechanical properties of polymers, and techniques for studying drug release kinetics ...
Há 9 horas · This study evaluates the viability of n-octanol as an alternative fuel in a direct-injection diesel engine, aiming to enhance sustainability and efficiency. Experiments fueled by different blends of n-octanol with pure diesel were conducted to analyze their impacts on engine performance and emissions. The methodology involved testing each blend in a single-cylinder engine, measuring engine ...
