Boron neutron capture therapy (BNCT) is a biochemically targeted form of radiotherapy for cancer. In BNCT, a compound labeled with the stable isotope boron-10 is systemically administered, and tumor cells selectively uptake the boron-10 containing compound at higher concentrations than normal cells. A general problem with the tumor seeking compounds is that drug delivery is dependent upon suffi...

The empty p z -orbital of a three-coordinate organoboron compound leads to its electron-deficient properties, which make it an excellent π-acceptor in conjugated organic chromophores. The empty p-orbital in such Lewis acids can be attacked by nucleophiles, so bulky groups are often employed to provide air-stable materials. However, many of these can still bind fluoride and cyanide anions leadin...

In dual workfunction gate technologies it can be observed, that p+ poly gates of pMOSFETs tend to lose boron doping. This work presents a model for the transport of Si and B in the TiSi~/polysilicon bilayer system that can explain the saturation of the B dose loss.

The effects of different boron doses (boron-free, pure boron, diluted in 1/2 and1/8 ratios) on the ratio and quality essential oil medicinal sage (Salvia officinalis L.) during years 2016 2017 were investigated. Field trials conducted with randomized block design triplicates. S. L. was obtained by gas chromatography/mass spectrometry (GC–MS) flame ionization detection (FID). required measuremen...

Various biological functions of Boron (B) compounds are known (Blevins & Lukaszewski, 1994; Tariq & Mott, 2007; Nielsen, 2008). Boron is found in nuts, vegetables, dried/fresh fruits and red wine (Brown & Shelp, 1997). Boron is also present in bacterial antibiotics, such as tartrolon, borophycin, boromycin and aplasmomycin (Rezanka & Sigler, 2008); in the bacterial quorum sensing molecule auto-...

Purpose Boron neutron capture therapy is a cellular-scale particle exploiting boron reactions in compounds distributed tumour cells. Its therapeutic effect depends on both the accumulation of cells and fluence. Autoradiography used to visualise micro-distribution compounds. Methods Here, we present an equation for relationship between concentration pit density solid-state nuclear track detector...

Boron/carbon/nitrogen (B/C/N) materials and boron/carbon (B/C) having graphite-like layered structures were synthesized by using a chemical vapor deposition (CVD) method. Calcium (Ca) was intercalated into the B/C reaction of Ca with host film to form an intercalation compound second stage structure as main product. also co-intercalated lithium (Li) B/C/N liquid-alloy method compound. These are...

During the last years the interest in silicon and boron carbonitrides developed remarkably. This interest is mainly based on the extraordinary properties, expected from theoretical considerations. In this time significant improvements were made in the synthesis of silicon carbonitride SiCxNy and boron carbonitride BCxNy films by both physical and chemical methods. In the Si–C–N and B-C-N ternar...
