Tuning Bro̷nsted Acidity by up to 12 p Units in a Redox-Active Nanopore Lined with Multifunctional Metal Sites.

Electrostatic interactions, hydrogen bonding, and solvation effects can alter the free energies of ionizable functional groups in proteins and other nanoporous architectures, allowing such structures to tune acid-base chemistry to support specific functions. Herein, we expand on this theme to examine how metal sites ( = H, Zn, Co, Co) affect the p of benzoic acid guests bound in discrete porphyrin nanoprisms () in CDCN. These host-guest systems were chosen to model how porous metalloporphyrin electrocatalysts might influence H transfer processes that are needed to support important electrochemical reactions (e.

Herbivore effects increase with latitude across the extent of a foundational seagrass.

Climate change is altering the functioning of foundational ecosystems. While the direct effects of warming are expected to influence individual species, the indirect effects of warming on species interactions remain poorly understood. In marine systems, as tropical herbivores undergo poleward range expansion, they may change food web structure and alter the functioning of key habitats.

Cage Match: Comparing the Anion Binding Ability of Isostructural Versus Isofunctional Pairs of Metal-Organic Nanocages.

Affinities of six anions (mesylate, acetate, trifluoroacetate, p-toluenecarboxylate, p-toluenesulfonate, and perfluorooctanoate) for three related Pt -linked porphyrin nanocages were measured to probe the influence of different noncovalent recognition motifs (e. g., hydrogen bonding, electrostatics, π bonding) on anion binding.

No impaired integration in psychopathy: Evidence from an illusory conjunction paradigm.

Progress in psychopathy research has been hampered by ongoing contention about its fundamental cause. The Impaired Integration theory of psychopathy provides an attention-based account of information integration abnormalities. We set out to evaluate the suggested mechanism via an innovative application of the well-established illusory conjunction paradigm.
