Clonal diversity of the glutamate dehydrogenase gene in Giardia duodenalis from Thai Isolates: evidence of genetic exchange or Mixed Infections?

open access: yes, 2011
Background: The glutamate dehydrogenase gene (gdh) is one of the most popular and useful genetic markers for the genotypic analysis of Giardia duodenalis (syn. G. lamblia, G. intestinalis), the protozoan that widely causes enteric disease in humans.

Nanoparticle Shape Dictates Catalytic Performance in Selective Hydrogenation of Butadiene Over Au‐Pd Core‐Shell Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Controlling the exposed crystal facet of shape‐controlled Au‐Pd core‐shell catalysts though colloidal synthesis enhances their catalytic performance in the industrially relevant selective hydrogenation of butadiene. ABSTRACT Selective hydrogenation of butadiene is a critical step in purification of alkene feedstocks for polymer production and is ...

A molecular cytogenetic study of intergenomic recombination and introgression of chromosomal segments in lilies (Lilium)

open access: yes, 2009
Lilies (Lilium L.) are one of the most important ornamental bulbous crops for cut flower industry grown extensively in The Netherlands for last few decades. The genus Lilium consists of seven different sections with about 80 species. The species within

Polarity‐Reversible Photoresponse–Driven Autonomous Wavelength Discrimination in Quantum Dot–Tellurium Thin‐Film Photodetectors via Engineered Energy‐Band Alignment

open access: yesAdvanced Functional Materials, EarlyView.
A quantum dot–tellurium thin‐film photodetector autonomously discriminates visible and infrared wavelengths through polarity‐reversible photoresponses. Engineered carrier separation and gain modulation enable filter‐free multispectral sensing within a single‐device architecture.

Efficient gene targeting and foreign DNA removal by homologous recombination in the picoeukaryote Ostreococcus [PDF]

open access: yes, 2014
With fewer than 8000 genes and a minimalist cellular organization, the green picoalga Ostreococcus tauri is one of the simplest photosynthetic eukaryotes. Ostreococcus tauri contains many plant-specific genes but exhibits a very low gene redundancy.

Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

open access: yesAdvanced Functional Materials, EarlyView.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.

Fregene: Simulation of realistic sequence-level data in populations and ascertained samples [PDF]

open access: yes, 2008
Background: FREGENE simulates sequence-level data over large genomic regions in large populations. Because, unlike coalescent simulators, it works forwards through time, it allows complex scenarios of selection, demography, and recombination to be ...

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

open access: yesAdvanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...
