Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.

Kin discrimination in tadpoles of Hylarana temporalis (Anura: Ranidae) and Sphaerotheca breviceps (Anura: Dicroglossidae) hydroperiod and social habits

open access: yesPhyllomedusa: Journal of Herpetology, 2014
Kin discrimination ability was studied in tadpoles of Hylarana temporalis and Sphaerotheca breviceps, which live in two distinctly different habitats; the former shows social aggregation and the latter live scattered. Early in development, tadpoles of H.

Unraveling Quantitative Sensing Mechanism and Predictive Molecular Metrics for High‐Performance OFET Amine Sensors

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a novel chloro boron subphthalocyanine/polymer blend OFET sensor achieving 0.005 ppb limit of detection for ammonia at room temperature and high selectivity against similar amines. An original theoretical framework is proposed to describe the sensing mechanism, relating analyte molecular volume and Lewis basicity to sensor ...

Influence of Habitat on the Impact of Non-Native Fishes on Native Ichthyofauna in a Group of Lakes of the Lower Doce River, Espírito Santo, Southeastern Brazil

open access: yesDiversity
The Doce River basin is the largest river system in southeastern Brazil. Over the last century, the Doce River has been undergoing a serious process of degradation, culminating in a huge environmental disaster due to Fundão tailing dam bursting in ...

New meteor showers identified in the CAMS and SonotaCo meteoroid orbit surveys

open access: yes, 2013
A cluster analysis was applied to the combined meteoroid orbit database derived from low-light level video observations by the SonotaCo consortium in Japan (64,650 meteors observed between 2007 and 2009) and by the Cameras for All-sky Meteor Surveillance

One Bad Apple Spoils the Bunch: Exploiting P2P Applications to Trace and Profile Tor Users [PDF]

open access: yes, 2011
Tor is a popular low-latency anonymity network. However, Tor does not protect against the exploitation of an insecure application to reveal the IP address of, or trace, a TCP stream.

Dual‐Layer Living Hydrogel Enables On‐Demand Delivery of Phages and Probiotics for Synergistic Wound Infection Therapy

open access: yesAdvanced Functional Materials, EarlyView.
A dual‐layer living hydrogel, ProΦGel, integrates bacteriophages and probiotics for synergistic wound infection therapy. The outer gelatin‐based matrix releases phages on demand in response to P. aeruginosa infections, while inner alginate beads sustain probiotic delivery.

Potential Health Implications of Heavy Metal Contamination of Streams Near Quarry Sites in Akamkpa, Cross River State, Nigeria

open access: yesStudia Ecologiae et Bioethicae
This study examined the potential health implications of heavy metal contamination of streams near quarry sites in Akamkpa, Cross River State. Three rural communities were selected (Awi, Nsan, Old Netim) and three streams near operating quarries were ...

Bioinspired Polypeptide Dendrimer‐Modified Thin‐Film Composite Membranes for Selective Lithium‐Magnesium Separation with DFT Insights

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated a biomimetic dendrimer‐modified thin‐film nanocomposite membrane with a coordination‐assisted ion‐selective interface. pH‐responsive polypeptide sites preferentially bind Mg2+ and promote Li+ permeation, as predicted by density functional theory calculations of metal‐ligand interactions.
