Water electrolysis is by far the most appealing method to produce green hydrogen. Among possible technologies, Anion Exchange Membrane (AEM) water electrolyzers are promising in medium term, as they make it avoid critical and noble materials catalyst components. However, AEMs still lacking performance stability, which has become current research focus. Here, we report facile inexpensive chemica...

The title heteropolyoxidotungstate-based inorganic-organic hybrid material, (C(6)H(12)N(5)O)(3)[W(12)(PO(4))O(36)]·6H(2)O, consists of one α-Keggin-type [W(12)(PO(4))O(36)](3-) polyoxidometalate anion (POM), three crystallographically independent 4-[(2H-tetra-zol-5-yl)meth-yl]morpholinium cations and six water mol-ecules of crystallization. The morpholine ring of the cation adopts a chair confo...

Lewis acidic silicates are effective catalysts for the conversion of glucose to bio-molecules industrial interest, such as methyl lactate and vinyl glycolate. Although well studied in rec...

The effectiveness of photorespiration as a protective mechanism against photooxidative stress and as a necessary pathway for the dissipation of excess photochemical energy in vascular C3 plants has been established (Kozaki and Takeba 1996, Wingler et al. 2000). Evidence for and against a functional photorespiratory pathway in photosynthetic chromoalveolates such as diatoms has been extensively ...

Highly nanoporous TiO(2) (anatase) spheres with an excellent ability in environmental applications have been successfully prepared via in situ hydrolysis of titanium glycolate precursor spheres.

The chemokine receptors CXCR1/2 are involved in a variety of inflammatory diseases, including chronic obstructive pulmonary disease. Several classes of allosteric small-molecule CXCR1/2 antagonists have been developed. The data presented here describe the cellular pharmacology of the acid and ester forms of the nicotinamide glycolate pharmacophore, a potent antagonist of CXCR2 signaling by the ...

A long period of drought leads to stomata1 closure, thus depriving most of the green cells of CO,. Under these conditions glycolate is formed rapidly inside the chloroplasts, via phosphoglycolate, from ribulose 1,s-bisphosphate by the oxygenase reaction of ribulose1,s-bisphosphate carboxylase/ oxygenase [ l , 21. The resulting glycolate is transported out of the chloroplasts to be metabolized t...

The addition of glyoxylate to tobacco (Nicotiana tabacum) leaf discs inhibited glycolate synthesis and photorespiration and increased net photosynthetic (14)CO(2) fixation. This inhibition of photorespiration was investigated further by studying the effect of glyoxylate on the stimulation of photosynthesis that occurs when the atmospheric O(2) level was decreased from 21 to 3% (the Warburg effe...
