Engineering aluminum hydroxyphosphate nanoparticles with well-controlled surface property to enhance humoral immune responses as vaccine adjuvants。
MicroRNAs (miRNAs) play important roles in response of plants to biotic and abiotic stresses. Aluminum (Al) toxicity is a major factor limiting plant growth in acidic soils. However, there has been li...
Both phosphorus (P) deficiency and aluminum (Al) toxicity induce root exudation of carboxylates, but the relationship between these two effects is not fully understood.Here, carboxylate exudation indu...
Inhibition of root elongation by toxic aluminum (Al3+) occurs rapidly and is one of the most distinct and earliest symptoms of Al toxicity. To elucidate mechanism underlying Al3+-induced inhibition of...
Aluminum (Al) is toxic to plants when solubilized into Al3+ in acidic soils, and becomes a major factor limiting plant growth. However, the primary cause for Al toxicity remains unknown.Nitric oxide (...
The trace metals aluminum (Al) and manganese (Mn) were studied in the Weddell Sea in March 2008.Concentrations of dissolved Al ([Al]) were slightly elevated (0.23–0.35 nmol L21) in the surface layer c...
We demonstrate wideband integrated photonic circuits in sputter-deposited aluminum nitride (AlN) thin films. At both near-infrared and visible wavelengths, we achieve low propagation loss in integrate...
We demonstrate high optical quality factors in aluminum nitride (AlN) photonic crystal nanobeam cavities. Suspended AlN photonic crystal nanobeams are fabricated in sputter-deposited AlN-on-insulator ...
Weathering products formed on the surface of K-feldspar in Yakushima Island, Japan were investigated by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron micros...
Terminal phenolic hydroxyl triazine dendrimer (HTHP) was prepared by putting cyanuryl chloride and 1,3,5-benzenetriol into acetone and then adding K2CO3 into the mixture as deacid reagent, which is ca...
The presence of elements heavier than helium in white dwarf atmospheres is often a signpost for the existence of rocky objects that currently or previously orbited these stars. We have measured the ab...
we investigated the magneto-electroluminescence (MEL) in tri-(8-hydroxyquinoline)-aluminum based organic light-emitting diodes (OLEDs) through the steady-state and transient method simultaneously. The...
A novel azo derivative, 2,3,4,6'-tetrahydroxy-3'-sulfoazobenzene (THSA), was synthesized by using pyrogallol. The acid dissociation constants, or Ka values, of THSA were determined by the UV-visible s...
Meteoritic data, especially regarding chondrules and calcium-rich, aluminumrich inclusions (CAIs), and isotopic evidence for short-lived radionuclides (SLRs)in the solar nebula, potentially can constr...
We shall analyze here the transmission of microwave-frequency electrical pulses through a \bimetallic" wire consisting of superconducting aluminum (Al) wire covered with a thick, nonsuperconducting co...
