High quantum yields mean that minim... | https://en.wikipedia.org/wiki?curid=33177861 |
Core–shell semiconductor nanocrystal The most popular core/shell pair used is CdSe core with ZnS or CdS shell, which improves the quantum yield and protects against photobleaching compared to that of the core material alone. The size of the CSSNC is directly correlated to the color of fluorescence, so being able to con... | https://en.wikipedia.org/wiki?curid=33177861 |
Core–shell semiconductor nanocrystal Also, it has been shown that five different toxins can be detected using five different CSSNCs simultaneously. In a move toward environmentally friendlier and less toxic CSSNCs, Si quantum dots with various shells have been developed. Si is 10 times safer than Cd and current work is... | https://en.wikipedia.org/wiki?curid=33177861 |
Core–shell semiconductor nanocrystal The main disadvantage of using CSSNCs for in vivo imaging is the lack of information about their excretion and toxicity. The typical cores used show DNA damage and toxicity toward liver cells, but using shells seems to diminish this effect. The use of other substances in the core, s... | https://en.wikipedia.org/wiki?curid=33177861 |
Core–shell semiconductor nanocrystal Specifically, the core–shell motif is desirable for use in LEDs because of their electroluminescence and photoluminescence quantum efficiencies and their ability to be processed into devices easily. Current aims for LED displays include developing materials with wavelength emissions... | https://en.wikipedia.org/wiki?curid=33177861 |
Core–shell semiconductor nanocrystal Type II CSSNCs separate the electrons and holes of the exciton pair, which leads to a strong electric field and thus, reducing absorption losses. By combining the modularity of CSSNCs and stability of organic polymer, a broad range of colors of phosphors were developed. CdSe core/Zn... | https://en.wikipedia.org/wiki?curid=33177861 |
Fossil stellar magnetic field Fossil stellar magnetic fields or "fossil fields" are proposed as possible interstellar magnetic fields that became locked into certain stars. | https://en.wikipedia.org/wiki?curid=33196287 |
Sculptor Wall The is a superstructure of galaxies ("wall of galaxies") relatively near to the Milky Way Galaxy (redshift of approximately z=0.03), also known as the Sculptor superclusters. The superstructure is also called "Southern Great Wall", "Great Southern Wall", "Southern Wall", in reference to the Northern Great... | https://en.wikipedia.org/wiki?curid=33196876 |

L-Ribonucleic acid aptamer An -ribonucleic acid aptamer (-RNA aptamer, trade name Spiegelmer) is an RNA-like molecule built from -ribose units. It is an artificial oligonucleotide named for being a mirror image of natural oligonucleotides. -RNA aptamers are a form of aptamers. Due to their -nucleotides, they are highly... | https://en.wikipedia.org/wiki?curid=33233736 |
L-Ribonucleic acid aptamer Unlike other aptamers, -RNA aptamers are not directly made using systematic evolution of ligands by exponential enrichment (SELEX), as -nucleic acids are not amenable to enzymatic methods, such as polymerase chain reaction (PCR), used in SELEX. Therefore, the selection is done with mirrored t... | https://en.wikipedia.org/wiki?curid=33233736 |
Tensiometer (soil science) A tensiometer in soil science is a measuring instrument used to determine the matric water potential (formula_1) (soil moisture tension) in the vadose zone. This device typically consists of a glass or plastic tube with a porous ceramic cup and is filled with water. The top of the tube has ei... | https://en.wikipedia.org/wiki?curid=33238388 |
Robert Smolańczuk (born in Olecko, Poland) is a Polish theoretical physicist. He received his doctorate from the Soltan Institute for Nuclear Studies in 1996. He later visited Lawrence Berkeley National Laboratory as a Fulbright Fellow between 1998-2000. He predicted in late 1998 that a lead-and-krypton collision techn... | https://en.wikipedia.org/wiki?curid=33241633 |
