Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

Advanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Africa's hotspots of biodiversity redefined

, 2004
A key problem for conservation is the coincidence of regions of high biodiversity with regions of high human impact. Twenty-five of the most threatened centers of plant diversity were identified by Myers et al., and these “hotspots” play a crucial role ...

Toroidal-poloidal partitioning of plate motions since 120 MA [PDF]

, 1993
Changes in plate motions and plate configurations during the Cenozoic and Mesozoic have been investigated extensively, but most geodynamical models have concentrated on present-day plate motions.

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

Advanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

A Pedigree-Based Map of Recombination in the Domestic Dog Genome

G3: Genes, Genomes, Genetics, 2016
Meiotic recombination in mammals has been shown to largely cluster into hotspots, which are targeted by the chromatin modifier PRDM9. The canid family, including wolves and dogs, has undergone a series of disrupting mutations in this gene, rendering ...

Graded Metallopolymer Structures with Shape‐Memory Abilities via DLP‐Based 3D‐Printing

Advanced Functional Materials, EarlyView.
This study presents the digital light processing (DLP) based 3D printing of graded metallopolymers featuring shape‐memory abilities. The permanent shape can be recovered in two distinct steps with excellent rates. The obtained graded prints range from simple rod‐like structures to complex hollow materials.

Stereometric Molecular Engineering for Ultra‐Stable Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
Stereochemical configuration of molecular additives greatly influences interfacial adsorption at the Zn surface. The optimal tilted dual‐anchored adsorption geometry of myo‐inositol constructs a water‐deficient interface and regulates the solvation structure.

Engineering a Fluorinated AlPO4 Interface: Toward High Initial Coulombic Efficiency and Stable Oxygen Redox in Li‐Rich Layered Oxide Cathodes

Advanced Functional Materials, EarlyView.
We report a chemically incorporated fluorinated AlPO4 (AlPO4‐F) architecture that functions as a multifunctional “interfacial fortress” for Li‐rich layered oxides (LLOs). By modulating the surface potential to –32.16 mV, this architecture enriches Li+ concentration and repels detrimental electrolyte anions.

¿La crisis de la biodiversidad es la crisis de la taxonomía?

Botan‪ical Sciences, 2015
El compromiso de integrar una lista florística que plasme el conocimiento de la diversidad vegetal a corto plazo, solamente será alcanzado con un cuerpo sólido de taxónomos especialistas, el cual, en lugar de fortalecerse, más bien parece estar en ...
