An electromagnetic pulse (EMP) explodes in real-time and causes critical damage within a short period to not only electric devices, but also to national infrastructures. In terms of EMP shielding rooms, metal plate has been used due to its excellent shielding effectiveness (SE). However, it has difficulties in manufacturing, as the fabrication of welded parts of metal plates and the cost of con...

Development of nontoxic, tumor-targetable, and potent in vivo RNA delivery systems remains an arduous challenge for clinical application of RNAi therapeutics. Herein, we report a versatile RNAi nanoplatform based on tumor-targeted and pH-responsive nanoformulas (NFs). The NF was engineered by combination of an artificial RNA receptor, Zn(II)-DPA, with a tumor-targetable and drug-loadable hyalur...

grasspea (lathyrus sativus) is a protein-rich forage legume that contains a neurotoxin (beta-odap) that causes severe malformation of the body’s extremities when eaten in large quantities. various low-toxin lines of grasspea have been developed to reduce the toxin’s concentration in the grain, i.e. to below the 0.2% critical value, but there are indications that zinc (zn) can also reduce the to...

A facile strategy is reported here for synthesis of Zn-Cu-In-S/ZnS (ZCIS/ZnS) core/shell QDs to address the synthetic issues that the unexpected blue-shift of CuInS(2)-based nanocrystals. In this strategy, Zn(2+) ions are intentionally employed for the synthesis of alloyed ZCIS core QDs before ZnS shell coating, which contributes to the reduced blue-shift in photoluminescence (PL) emission. The...

Much of the information we are seeing at this symposium revolves around the utility of Zn rich coatings. Marine Environmental Research (MER) has been examining these coatings as the material component in a surface protective system applicable to both marine and land based needs. The nonmaterial component of this system is electrical. The way these two components interact and the surprising resu...

Female reproductive tissues such as mammary glands, ovaries, uterus, and placenta are phenotypically dynamic, requiring tight integration of bioenergetic and apoptotic mechanisms. Mitochondrial zinc (Zn) pools have emerged as a central player in regulating bioenergetics and apoptosis. Zn must first be imported into mitochondria to modulate mitochondrion-specific functions; however, mitochondria...

P. Pokorny, J. Kolisko, L. Balik – Czech Technical University – Klokner Institute, Prague, Czech Republic P. Novak – Institute of Chemical Technology, Prague, Czech Republic This review article mainly describes the composition of intermetallic Fe Zn, i.e. zeta (ζ), delta (δ1k + δ1p), gamma1 (Γ1) and gamma (Γ) on galvanized steel during low temperature galvanization (t ~ 450 °C). It gives detail...

Cooling rates of 10 -3 K/yr. permit naturally occurring Mn-Zn ferrites (franklinltes) to be in thermodynamic equilibrium at ambient temperatures with respect to both electrostatic and elastic energies. The elastic strain energy resulting from the occupancy of the A sites by ions of differing sizes is minimized by clustering of.Mn and Zn in different regions of a D/ crystal. Using Fe NGR, these ...

Chemical-mechanical separation of pig slurry into a solid fraction rich in dry matter, P, Cu and Zn and a liquid fraction rich in inorganic N but poor in dry matter may allow farmers to manage surplus slurry by exporting the solid fraction to regions with no nutrient surplus. Pig slurry can be applied to arable land only in certain periods during the year, so it is commonly stored prior to fiel...

The aqueous corrosion resistances of galvalume (FeAl+Zn) and steel galvanized (Fe-Zn) alloys, passivated by immersion in chromating solution with different immersion times (0, 10, 30 y 60 s) are compared. The electrochemical behaviour of various chromated and non-chromated coatings was investigated in 3 wt-% NaCl solution using polarization techniques. For comparison, AISI 1010 carbon steel sub...
