A Host‐Guest, Zeolite/Organocation Material With Isotropic Zero Thermal Expansion

Advanced Functional Materials, EarlyView.
The use of selected organic structure directing agents for the hydrothermal synthesis of targeted zeolites exhibiting negative thermal expansion provides a straightforward strategy to obtain a new class of host‐guest, nanostructured, crystalline zero thermal expansion materials made of light and abundant elements.

MXene/PEDOT Functional Coatings on Flexible Microelectrode Arrays for Multianalyte In Vivo Neurochemical Sensing and Electrophysiology

Advanced Functional Materials, EarlyView.
A MXene/PEDOT coating enables multimodal functionality and dual‐analyte detection of dopamine and serotonin in flexible microelectrode arrays while enhancing electrophysiological recording quality. The anti‐fouling, low‐impedance interface overcomes key limitations of conventional coatings, providing a robust and versatile platform to investigate the ...

How the Carrier Mobility and Seebeck Coefficient of Doped Semiconducting Polymers Are Controlled by Counterion Interactions and Mesoscale Order

Advanced Functional Materials, EarlyView.
Conventional doping of P3HT with F4TCNQ results in poor charge transport. However, when F4TCNQ is exchanged with LiTFSI, the transport characteristics are greatly enhanced. We find the increase in charge transport is directly related to an increase in the mesoscale ordering of P3HT, resulting in longer and better‐connected transport pathways.

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Memristor‐Driven Active‐Matrix Organic Light‐Emitting Diode for Energy Efficient and High‐Resolution Displays

Advanced Functional Materials, EarlyView.
This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).

Bacterial Insertion Sequences

1996
While DNA has a property of being fundamentally stable as invariable genetic information, studies on gene expression and gene organization have revealed that the genome is often subject to dynamic changes. Some of these changes are brought about by mobile genetic elements which have been found in prokaryotic and eukaryotic genomes so far studied ...

Structural analysis of insertion sequence IS5

Nature, 1982
Among the transposable DNA elements that have been detected in bacterial genomes and plasmids1–3, the small insertion sequence (IS) elements have been recognized as a class of autonomous, basic units of transposition. IS elements are not only fully competent of transposition and able to cause several other related chromosomal aberrations such as ...

Insertion sequence elements in Lactococcus garvieae

Gene, 2015
Insertion sequences are the simplest intracellular Mobile Genetic Elements which can occur in very high numbers in prokaryotic genomes, where they play an important evolutionary role by promoting genome plasticity. As such, the studies on the diversity and distribution of insertion sequences in genomes not yet investigated can contribute to improve the

IS200: A salmonella-specific insertion sequence

Cell, 1983
A new IS element (IS200) has been identified in Salmonella. The sequence was identified as an IS element by the following criteria: its insertion caused the mutation hisD984; six copies of the sequence are present in strain LT2 of S. typhimurium; and transposition of the sequence has been observed on several occasions.
