Turning Unpredictable Biomolecule Adsorption to Controlled Corona Formation: Focus on Carbon Nanomaterials

open access: yesAdvanced Materials, EarlyView.
Controlling the protein corona formation onto carbon nanomaterials (CNMs) enhances their functionalities as platforms for cancer theranostics. Here, we reviewed the effects of the intrinsic and acquired properties of CNMs on protein corona formation, the consequent biological and toxicological outcomes, and the strategies to reshape corona formation ...

Tuning chirality in photonic metamaterials with semiconductor quantum dots [PDF]

open access: yes, 2009
Recently we have shown that the classical phenomenon of optical activity, which is traditionally associated with chirality (helicity) of organic molecules, proteins and inorganic structures, can be observed in artificial planar media which exhibit ...

Oxidising agent and catalyst chirality effect on epoxidation of R-(+)-Limonene using Jacobsen-type catalysts

open access: yesIngeniería e Investigación, 2008
The oxidising agent effect on R-(+)-Limonene epoxide diastereoselectivity using chiral and achiral Jacobsen’s type catalysts is presented. The type of oxidising agent strongly influences diastereoselectivity.

Measuring the Hall Effect in Hysteretic Materials

open access: yesAdvanced Materials, EarlyView.
The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...
