Berkelium is a soft, silvery-white, radioactive actinide metal

Understanding of waves and their interactions with matter has been used to design technologies and instruments that greatly extend the range of phenomena that can be investigated by science (e.g., telescopes, microscopes) and have many useful applications in the modern world.

. Multiple technologies based on the understanding of waves and their interactions with matter are part of everyday experiences in the modern world (e.g., medical imaging, communications, scanners) and in scientific research. They are essential tools for producing, transmitting, and capturing signals and for storing and interpreting the information contained in them.

06/11/2013 · Sarina, Sarina (2013) New catalysts for organic synthesis driven by light and efficient sorbents for removal of radioactive ions from water.

The body of the thesis contained two separate elements which made an original contribution to fundamental understanding in the areas of photocatalysis, chemical synthesis and water treatment. Research on chemical reactions catalyzed by noble metal nanoparticles (such as gold) or surface complex grafted metal oxides which can be driven by sunlight at ambient temperature and the second element on radioactive cesium (137Cs+) cations and iodine (125I-) anions recovery by the unique structural features of titanate nanostructures for firmly capture and safe storage; the works has been all published in journals that are rated at the top of their respective fields.

The patient is then irradiated with neutrons which are strongly absorbed by the boron, to produce high-energy alpha particles which kill the cancer.

For targeted alpha therapy (TAT), actinium-225 is readily available now, from which the daughter Bi-213 can be obtained (via 3 alpha decays) to label targeting molecules.

Considerable medical research is being conducted worldwide into the use of radionuclides attached to highly specific biological chemicals such as immunoglobulin molecules (monoclonal antibodies).

Irène and Frédéric were indeed awarded the 1935 Nobel Prize in Chemistry, “in recognition of their synthesis of new radioactive elements

In some cases radiation can be used to treat diseased organs, or tumors.

In developed countries (26% of world population) the frequency of diagnostic nuclear medicine is 1.9% per year, and the frequency of therapy with radioisotopes is about one tenth of this.

Nuclear medicine was developed in the 1950s by physicians with an endocrine emphasis, initially using iodine-131 to diagnose and then treat thyroid disease.

According to the NCBJ release, a cyclotron capable to accelerate protons (to the energy of 30 MeV), deuterons (to 15 MeV) and alpha particles (to 30 MeV) will be the heart of the CERAD centre. Such energies are sufficient to produce radioactive isotopes needed in nuclear medicine; such isotopes are produced that way only in very few institutions in the world. In addition, some isotopes will be produced by means of irradiating suitable targets with beams of neutrons produced by the MARIA reactor in Świerk. The new centre building will house labs equipped with hot chambers necessary to safely manipulate radioactive materials, analytical labs and biology labs.

The artificial creation of radio-elements opens a new field to the science of radioactivity and so provides an extension of the work of Pierre and Marie Curie.

Chemistry Nobel in 1935 for creating new radioactive elements, ..

The dependence of the reactioncross-section (HI, 5-6n) on the atomic number of the compound nucleus indifferent target-ion combinations points to the possibility ofsynthesizing new elements in hot fusion reactions.

Discovery and Assignment of Elements with Atomic …

The substructure of atoms determines how they combine and rearrange to form all of the world’s substances. Electrical attractions and repulsions between charged particles (i.e., atomic nuclei and electrons) in matter explain the structure of atoms and the forces between atoms that cause them to form molecules (via chemical bonds), which range in size from two to thousands of atoms (e.g., in biological molecules such as proteins). Atoms also combine due to these forces to form extended structures, such as crystals or metals. The varied properties (e.g., hardness, conductivity) of the materials one encounters, both natural and manufactured, can be understood in terms of the atomic and molecular constituents present and the forces within and between them.
