Egyptian Journal of Remote Sensing and Space Sciences, 2010 Garin Hawal area, Kebbi State, NW Nigeria is part of the Neoproterozoic to Early Phanerozoic terrane separating the west African and Congo Cratons. Three main gold-bearing shear zones were detected in the study area from the processed Landsat ETM+ images

Radiospectroscopy of vein quartz of the subpolar ural deposits [PDF]
Acta Crystallographica Section A Foundations of Crystallography, 2006 Nano-crystalline calcium silicate hydrates (C-S-H gels) are formed upon hydration of Ca3SiO5 and β-Ca2SiO4, and are therefore the primary hydration products of Portland cements. Raman and IR spectra of a series of mechanochemically prepared C-S-H samples of type C-S-H(1) with Ca/Si ratios ranging from 0.4 to 1.5 reveal changes in structure dependent ...

Small, EarlyView.Interactions with biomolecules can alter the photoluminescence of Ag2S nanocrystals, undermining near‐infrared imaging and thermometry. Incorporation into dendritic silica minimizes these interactions and preserves emission intensity, spectral response, and lifetime in plasma and whole blood. This shielding enables more reliable imaging and temperature

Smart Molecules, EarlyView.A hydrogen‐bond‐donating NO donor was designed to interact specifically with the hydrogel network, thereby minimizing donor leakage and achieving prolonged NO release. Abstract Nitric oxide (NO)‐releasing materials have attracted considerable interest for their potential in diverse biomedical applications.

SusMat, EarlyView.This graphical ToC illustrates a tubular‐inspired detoxifier (SDCMs–DS) that halts acute kidney injury progression. Inspired by proximal tubular epithelial cells (PTECs), the biomimetic design combines dissociation‐adsorption clearance of protein‐bound uremic toxins (PBUTs) with antioxidant protection. During hemoperfusion, danshensu (DS) released from

“White and Clear” (WaC): A tunable hydrophilic tissue clearing strategy for multi‐species 3D imaging
VIEW, EarlyView.Optical tissue clearing methods help scientists make tissues transparent to image structures deep inside organs in 3D, but many existing techniques are limited in performance and difficulty. In this study, we developed an optimized clearing method called WaC (White and Clear), which improves upon existing techniques by combining efficient tissue ...

Applied SciencesThe Chuankou deposit is a super-large W deposit formed during the Indosinian collision event in South China, and its mineralization is suggested to be related to the Indosinian muscovite granite. However, two types of W mineralizations were discovered in

Archaeometry, EarlyView.ABSTRACT The hypotheses of Senonian flint to be a prime source of prehistoric “chalcedony” flint artefacts from the Negev Desert (Israel) was not investigated in detail thus far. By combining trace‐element profiling with statistical interpretation, ten flint items from Nahal Zahal, an Early Pre‐Pottery Neolithic B site in the northern Negev, were ...
