Spectrally-constrained diffuse tomography is used to image endogenous and exogenous tissue chromophore concentrations with higher accuracy than when using individual wavelengths. Reconstructed images from simulated data demonstrate that concentrations of Lutetium Texaphyrin are readily recovered. ©2005 Optical Society of America OCIS codes: (170.3880) Medical and biological imaging; (170.6960) ...

The components of the impedance, impedance Lu x Mn 1-x S (x<0.2) solid solution in temperature range 80-500 K and frequency 100-10 6 Hz were studied. A change sign magnetoimpedance concentration is found. contribution reactive active to determined. correlation temperatures with maximum attenuation ultrasound electrosound has been established. dependences part are described Cole-Cole mode...

The paper by Dasenbrock-Gammon, et al. Nature, volume 615, pages 244–250 (2023), does not present evidence for true superconductivity at near ambient temperature in a N-doped lutetium hydride system.

Laser experiments on 1.5at.%, 5at.%, and 8at.% thulium-gadolinium-lutetium-yttrium co-doped, buried, ridgetype channel waveguides in a monoclinic potassium double tungstate demonstrate a maximum slope efficiency of 70% and output powers of 300 mW at ~1.9 μm.

UNLABELLED The incidence and prevalence of gastroenteropancreatic neuroendocrine tumors has been increasing over the past 3 decades. Because of high densities of somatostatin receptors (sstr)--mainly sstr-2--on the cell surface of these tumors, (111)In-diethylenetriaminepentaacetic acid-octreotide scintigraphy has become an important part of clinical management. (18)F-radiolabeled analogs with ...

Synthetic procedures to obtain size and shape-controlled microparticles hold great promise achieve structural control on the microscale of macroscopic ceramic- or composite-materials. Lutetium oxide is a material relevant for scintillation due its high density possibility dope with rare earth emitter ions. However, sesquioxides are challenging synthesise using bottom-up methods. Therefore, calc...

The first T(d)-symmetric lutetium metallofullerene, Lu(2)@C(76), has been synthesized, isolated, and characterized. Because of the charge transfer from the encapsulated Lu atoms to the T(d)-C(76) fullerene cage, the otherwise unstable T(d)-C(76) fullerene can be significantly stabilized as a Lu(2)@C(76) fullerene. Both STM and STS results are consistent with a charge state of (Lu(2))(6+)@C(76)(...
