Currently, treatment of chronically infected wounds still remains a big challenge; thus, a novel strategy with a highly efficient therapeutic effect is of urgent demand. In the present work, we demonstrated that combinational use of nitric oxide (NO) and deferoxamine (DFO) is a promising way for treating hard-to-heal wounds. As a proof of concept, DFO was first loaded in mesoporous polydopamine (mPDA)

Owing to their excellent mixed-ionic and electronic conductivity, fast oxygen kinetics, and cost efficiency, layered oxygen-deficient perovskite oxides hold great potential as highly efficient cathodes for solid oxide fuel cells and anodes for water oxidation. Under working conditions, cation ordering is believed to substantially enhance oxygen diffusion while maintaining structural stability owing

Since its inception in 2020, LatinXChem has been raising the profile of research from Latin American chemists located anywhere in the world through a yearly virtual poster session. The event is accompanied by workshops and webinars on a range of topics, being a particularly exciting online event connecting people globally in an era when travel has been restricted. In 2021, Germán E. Gomez and Galo

Two-dimensional (2D) materials and transition metal dichalcogenides (TMD) in particular are at the forefront of nanotechnology. To tailor their properties for engineering applications, alloying strategies─used successfully for bulk metals in the last century─need to be extended to this novel class of materials. Here we present a systematic analysis of the phase behavior of substitutional 2D alloys

Understanding the complex crystallization process of semiconducting polymers is key for the advance of organic electronic technologies as the optoelectronic properties of these materials are intimately connected to their solid-state microstructure. These polymers often have semirigid backbones and flexible side chains, which results in a strong tendency to organize/order in the liquid state. Therefore

A guideline for zeolite phase selection in inorganic synthesis media is proposed, based on a systematic exploration of synthesis from inorganic media using liquid Na+, K+, and Cs+ aluminosilicate. Although the Si/Al ratio of the zeolites is a continuous function of the synthesis conditions, boundaries between topologies are sharp. The here-derived phase selection criterion relates the obtained zeolite

“Giant” core/thick-shell quantum dot (QD) nanostructures are of interest due to their unusual optical properties and importance as components of more advanced heterostructures tailored to achieve increasingly complex optical functions. However, reliable one-step seeded growth of these structures poses a significant challenge: one must balance multiple competing reaction processes to find the growth

The solution-based colloidal synthesis of multinary semiconductor compositions has allowed the design of new inorganic materials impacting a large variety of applications. Yet there are certain compositions that have remained elusive─particularly quaternary structures of transition metal-based (e.g., Co, Zn, Ni, Fe, Mn, and Cr) copper antimony chalcogenides. These are widely sought for tuning the electrical

Lithium insertion materials are an essential class of mixed ionic and electronic conductors, and their electrochemical properties depend on the resistive and capacitive interplay of ions and electrons. However, complete sets of the corresponding elementary material parameters, that is, composition-dependent ionic and electronic conductivity, chemical capacitance, and charge-transfer resistance, are

Al1–xGdxN is one of a series of novel heterostructural alloys involving rare earth cations with potentially interesting properties for (opto)electronic, magnetic, and neutron detector applications. Using alloy models in conjunction with density functional theory, we explored the full composition range for Al1–xGdxN and found that wurtzite is the ground-state structure up to a critical composition of

Less than 10% of plastics are recycled worldwide, among which polyolefins, which form two-thirds of all produced polymers, are the most discarded ones. This stems from the nonpolar nature of polyolefins, which limits their degradation and recycling. As such, any approach that may promote the recycling of polyolefins can significantly shift the statistics of polymer recycling toward a more sustainable

Herein, we describe the synthesis of the first boron nitride-doped polyphenylenic material obtained through a [4 + 2] cycloaddition reaction between a triethynyl borazine unit and a biscyclopentadienone derivative, which undergoes organogel formation in chlorinated solvents (the critical jellification concentration is 4% w/w in CHCl3). The polymer has been characterized extensively by Fourier-transform

We designed porous polymers with a tungsten-calix[4]arene imido complex as the nitrosamine receptor for the efficient extraction of tobacco-specific nitrosamines (TSNAs) from water. The interaction between the metallocalix[4]arene and the TSNA, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (nicotine-derived nitrosamine ketone, NNK) was investigated. We found that the incorporation of the nitrosamine

Discovery of new high-entropy electrocatalysts requires testing of hundreds to thousands of possible compositions, which can be addressed most efficiently by high-throughput experimentation on thin-film material libraries. Since the conditions for high-throughput measurements (“screening”) differ from more standardized methods, it is frequently a concern whether the findings from screening can be transferred

Carbon-supported platinum–lanthanide alloy nanoparticles are promising fuel-cell-cathode catalysts with enhanced electrocatalytic performance, but synthetic challenges remain because of high O affinity and very negative reduction potential of lanthanide elements. Herein, we demonstrate an industrially relevant impregnation approach for the general synthesis of a carbon-supported intermetallic hexagonal

In Figure 2b,c and Figure 5c, in which we have presented the octahedral mismatches (Δμ), formation energies (Ef), and room-temperature vibrational anharmonic scores (σ(2)) as a function of the octahedral (μ̅) and tolerance (t) factors, respectively, for halide double perovskites, different markers were used aiming to differentiate the halide anions. This information was further presented in Figure

The present work proposes and establishes a universal strategy toward facilitating the development of desired structural types (viz., P-type vs O-type) of “layered” Na- transition metal (TM) oxides, with the desired Na-content and properties. In this regard, the structure type, allowable Na-content, and Na-layer/“inter-slab” spacing have been found to depend on the “charge:size” ratio of the TM-ions

Metal halide perovskites with quasi-2D crystal structures have shown excellent electroluminescent properties due to the inherently confined charge diffusion and efficient radiative recombination. But quasi-2D perovskite films can exhibit complex phase characteristics that need to be tailored for achieving high-performance light-emitting diodes (LEDs). Here, we report a unique quasi-2D perovskite thin

We present a group of seven new advanced symmetric iodonium salts bearing two benzylidene-based chromophores. This is the first example of the use of a double bond in the structure of a symmetric iodonium salt. Such an improvement ensures excellent absorbing properties in the UV-A and visible range, representing a significant advance over the commonly used diaryliodonium salts. New symmetric iodonium

A prerequisite for the realization of solid-state batteries is the development of highly conductive solid electrolytes. Li3PS4 is the archetypal member of the highly promising thiophosphate family of Li-ion conductors. Despite a multitude of investigations into this material, the underlying atomic-scale features governing the roles of and the relationships between cation and anion dynamics, in its

The understanding and control of colloidal nanocrystal syntheses are essential for discovery and optimization of desired properties and therefore play a key role in the applications of these materials. Typical one variable at a time (OVAT) methods limit the ability of researchers to achieve such goals by providing one-dimensional insight into a complex, multidimensional experimental domain, wasting
