Oxygen evolution mediated by co-based thin film electrocatalysts
… of action, and mechanism of formation at intermediate pH are elaborated. The catalyst is obtained as an electronically conductive, porous thin film by electrolysis of Co2 in aqueous phosphate, methylphosphonate, or borate electrolyte. Catalyst films prepared from phosphate are comprised of …

Antibody Purification from Tobacco by Protein A Affinity Chromatography
Antibodies represent the largest group of biopharmaceuticals. Due to the nature of their clinical applications, they often need to be produced in large quantities. Plants have distinct advantages of producing large quantities of recombinant proteins, and tobacco is arguably the most promising plant …

FROM TURF TO TURF: FUNGAL INVASION OF ASCOCORYNE TURFICOLA IN A NORTHERN MICHIGAN BOG
… were <em>Rhynchospora alba </em>and <em>Eriophorum virginicum</em>. Although not indicator species, ericaceous shrubs were present in 100% of plots with <em>A. turifcola</em>, suggesting a possible ericoid mycorrhizal relationship (ERM), which is especially common among fungi in the …

Acid-base regulation in the sea urchin Parechinus angulosus during CO₂-induced seawater acidification
… is predicted to have adverse effects on the physiologies of marine organisms, particularly those that produce calcified structures. Extracellular homeostasis is considered to be critical to mediating the effects of ocean acidification. Due to their low metabolic rates and weak ability to …

The Biological Basis for Toughness in Beef
… at -1.5°C for up to 28 days post mortem. High (pH ≥ 6.2) and low (≤ 5.79) ultimate pH (pHu) at were acceptably tender within 1 and 7 days post mortem, respectively. Tenderness in these pHu groups is attributed to the extensive degradation of titin, nebulin, filamin and desmin by endogenous …

Characteristics and mechanisms of atrazine sorption to biochar for land remediation
… overall sorption for all other biochars. pH was shown to significantly influence the occurrence of various sorption mechanisms. At low pH values, most biochars showed evidence of electrostatic repulsion between positive atrazine species and the positively charged biochar surface. At …

DEVELOPMENT AND OPTMIZATION OF POLYELECTROLYTE POLYMER BRUSHES FOR THE FRACTIONATION OF PEPTIDE AND PROTEIN MIXTURES PRIOR TO MALDI MASS SPECTROMETRY ANALYSIS
… the most effective fractionation occurred at intermediate pH values, while poor separation occurred when fractionation was carried out at higher or lower pH. Lastly, to probe the potential greater capacity of the anionic polymer brush for uptake of peptides, two approaches were employed to …

Synthesis and rheology of pH-responsive particles with shape anisotropy
… produce large quantities of shape anisotropic, amphoteric particles in a size range of about 1 µm. Two different kinds of shape anisotropic particles are prepared for comparison to study the effects of incorporating pH-responsive groups on the properties of suspensions containing shape anisotropic …

Star-shaped Polyelectrolytes
… PDMAEMA were investigated. PDMAEMA is both pH-sensitive as temperature-sensitive, showing a miscibility gap at higher temperatures (LCST behavior). PDMAEMA shows a typical Flory-Huggins behavior irrespective to polymers architecture at high pH (in buffer), where it is virtually uncharged. …
