Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

open access: yesAdvanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Wide-bandwidth mode-hop-free tuning of extended-cavity GaN diode lasers [PDF]

open access: yes, 2005
We present a new approach for extended-cavity diode-laser tuning to achieve wide mode-hop-free tuning ranges. By using a multiple piezoactuated grating mount, the cavity length and grating angle in the laser can be adjusted independently, allowing mode ...

Identification of apple scab and powdery mildew resistance genes in Czech apple (Malus × domestica) genetic resources by PCR molecular markers

open access: yesCzech Journal of Genetics and Plant Breeding, 2011
The presence of genes for resistance to scab (Venturia inaequalis) and powdery mildew (Podosphaera leucotricha) was studied using molecular markers in a sample of 279 apple cultivars from the Czech collection of apple genetic resources.

GeS as an Emerging OTS Material: Atomic Structure and Modeling of ON/OFF Switching

open access: yesAdvanced Functional Materials, EarlyView.
The structural puzzle of glassy GeS, an advanced memory‐selector material, has finally been disentangled, revealing a patchwork of mixed tetrahedral and trigonal species. Under a high electric field, over‐ and under‐coordinated Ge and S defects, together with three‐membered rings, form an interconnected network associated with localized and extended ...

Dirac Semimetallicity Enabled by Stripe Antiferromagnetism in Monolayer FeSe

open access: yesAdvanced Functional Materials, EarlyView.
In monolayer FeSe, stripe antiferromagnetic order selectively breaks mirror symmetry, enabling odd inter‐orbital hybridization between opposite‐parity Fe 3d states. This mechanism stabilizes symmetry‐protected Dirac nodes with nontrivial Wilson‐loop topology and edge states, accompanied by a strong orbital diamagnetic susceptibility as an experimental ...

Evaluation of variability in alpha and beta acid content in European hop varieties (Humulus lupulus L.)

open access: yesKvasný průmysl
Between 2009 and 2023, European hop varieties were evaluated within genetic resources in the Czech Republic. The objective of this paper was to determine the variability of hop alpha and beta acid contents in the monitored varieties at a single site over

Impact of source and application time of sulphur on the yield, oil content and protein content in winter oilseed rape

open access: yesActa Agriculturae Slovenica, 2008
At the experimental field of Slovenian Institute of Hop Research and Brewing at Žalec an experiment was conducted in 2006/07 to detect the impact of fertilization by K2SO4 and gypsum on the yield, oil content, oil yield, protein content, protein yield ...

Molecular Bridges for 2D Nanomaterials

open access: yesAdvanced Functional Materials, EarlyView.
Molecular cross‐linking provides a versatile strategy to engineer interfaces in 2D materials. By tuning the linker backbone, binding mode, and interflake spacing, molecular bridges can regulate charge transport, mechanical integrity, chemical functionality, and processing.

EVALUATION OF GENETIC VARIABILITY WITHIN SWEET CHERRY (Prunus avium L.) GENETIC RESOURCES BY MOLECULAR SSR MARKERS

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2019
Sweet cherry is a vegetatively propagated, perennial plant with high level of heterozygosity and ancient breeding history. Therefore, it is necessary to keep, conserve and evaluate known genetic resources for fu- ture breeding programs and fruit ...

Modulation of Surface‐Associated Transport in (Bi1‐xSbx)2Te3 via Battery‐ Inspired Solid‐State Iontronic Gating

open access: yesAdvanced Functional Materials, EarlyView.
Iontronic gating in a battery‐inspired device modulates the relative weight of surface‐associated and bulk‐like transport fingerprints in (Bi1‐xSbx)2Te3, resulting in phenomenological valve‐like transport behavior. The strongest WAL‐associated coherent transport signatures emerge near the transport‐defined carrier compensation regime at ultra‐low gate ...
