Resolving the Cu(bdc) Conundrum: Identifying Non‐Porous Packing of Prototypical Coordination‐Network Thin Films Combining Advanced Diffraction Techniques and Computational Modelling

Advanced Functional Materials, EarlyView.
Solution‐processed Cu(bdc) forms prototypical MOF thin films for which a multitude of not fully satisfactory structural models have been suggested. Combining rotating grazing‐incidence diffraction and X‐ray reflectivity on two complementary samples with density‐functional theory, we first discard the previously suggested models and then identify a non ...

On lattices of varieties of restriction semigroups

Semigroup Forum, 2012
In the abstract of the paper the author writes: ``The left restriction semigroups have arisen in a number of contexts, one being as the abstract characterization of semigroups of partial maps, another as the `weakly left E-ample' semigroups of the `York school', and, more recently as a variety of unary semigroups defined by a set of simple identities.''

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

Advanced 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.

Dolomite, drainage, organic manure, and natural phosphate utilization to mitigate the effect of iron and sulfide toxicity on rice productivity in irrigated rice fields: case of Burkina Faso

Discover Agriculture
Rice cultivation in Burkina Faso faces major constraints from iron and sulfide toxicities that reduce rice productivity. This study investigated strategies to mitigate these stresses through improved drainage, fertilization, and variety selection across ...

Screening of Bread Wheat (Triticium astivum L.) Genotypes Against Septoria Tritici Blotch (Mycosphaerella graminicola) in North Gondar, Ethiopia

Blue Nile Journal of Agricultural Research, 2022
Bread wheat is one of the most important cereal crops grown in different parts of Ethiopia. However, its production was affected by foliar diseases. Mycosphaerella graminicola is among the most important ones.

Unraveling the Electronic Structure of Silicon Vacancy Centers in 4H‐SiC

Advanced Functional Materials, EarlyView.
The electronic structure of the silicon vacancy in 4H‐SiC is probed via transient absorption spectroscopy, uncovering previously inaccessible excited states of the quartet and doublet spin channels, including the V2' transition. In combination with theoretical analysis, a comprehensive picture of the electronic structure is established.

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

The subregular variety to the variety of special lattices

Journal of Pure and Applied Algebra, 2011
Let \(k\) be the algebraic closure of a finite field of characteristic \(p\) and let \(\mathcal{O}\) be the \(k\)-points of the Witt vectors and \(K\) the fraction field of \(\mathcal{O}\). Let \(F=\mathcal{O}^n\subset K^n\) be the standard inclusion. A lattice \(L\) as usual will be a free \(\mathcal{O}\)-submodule of rank \(n\) of \(K^n\).

Toward Fast Proton Shuttling in Acidic Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
This review establishes proton transfer dynamics as a descriptor governing acidic OER activity, moving beyond the kinetic constraints derived from the proton coupled electron transfer. We discuss how deprotonation governs classical mechanisms, including adsorbate evolution mechanism (AEM), lattice oxygen mechanism (LOM) and oxide path mechanism (OPM ...
