Spin-glass behavior and zero-field-cooled exchange bias in a Cr-based antiperovskite compound PdNCr 3
The nature of spin-glass behavior and zero-field-cooled exchange bias of antiperovskite PdNCr 3 has been confirmed via the combination of experiment measurements and theoretical calculations.
Insight into the strong aggregation-induced emission of low-conjugated racemic C6-unsubstituted tetrahydropyrimidines through crystal-structure–property relationship of polymorphs
Racemic low-conjugated non-emissive THPs 1–3 can form highly emissive RS - and RR / SS -packing polymorphs with mixed through-bond and through-space conjugation.
Rose Bengal incorporated in mesostructured silica nanoparticles: structural characterization, theoretical modeling and singlet oxygen delivery
Rose Bengal (RB), a xanthene dye, incorporated into mesostructured silica nanoparticles (MSNs) exhibits efficient singlet oxygen ((1)O2) generation when illuminated with 540 nm green light which is particularly promising for PDT applications. Several systems with different RB loadings were synthesized and fully charac…
Apigenin mediated gold nanoparticle synthesis and their anti-cancer effect on human epidermoid carcinoma (A431) cells
Apigenin reduces Au 3+ to Au 0 to form ap-AuNPs at RT. ap-AuNPs are biocompatible towards HaCat cells. They show anti-cancer activity towards A431 cells by inducing apoptosis.
New Ni( ii ) 1,2-bis(diphenylphosphino)ethane dithiolates: crystallographic, computational and Hirshfeld surface analyses
Three new Ni( ii ) dppe dithiolates have been synthesized and the nature of weak interactions have been addressed using computational and Hirshfeld surface analyses.
Atmospheric plasma-sprayed La 0.8 Sr 0.2 Ga 0.8 Mg 0.2 O 3 electrolyte membranes for intermediate-temperature solid oxide fuel cells
La 0.8 Sr 0.2 Ga 0.8 Mg 0.2 O 3 (LSGM) is considered a promising electrolyte material for intermediate-temperature solid oxide fuel cells (IT-SOFCs) because of its high ionic conductivity.
Construction of Zinc Oxide into Different Morphological Structures to Be Utilized as Antimicrobial Agent against Multidrug Resistant Bacteria
Nano-ZnO has been successfully implemented in particles, rods, and tubes nanostructures via sol-gel and hydrothermal techniques. The variation of the different preparation parameters such as reaction temperature, time, and stabilizer agents was optimized to attain different morphological structures. The influence of t…
Structural and dielectric anomalies near the MPB region of Na 0.5 Bi 0.5 TiO 3 –SrTiO 3 solid solution
In the present attempt, (1 − x )NBT(Na 0.5 Bi 0.5 TiO 3 )– x ST(SrTiO 3 ) ( x = 0.24–0.28) solid solutions are studied near the MPB region to investigate short-range structural and dielectric anomalies.
Quick synthesis of zeolitic imidazolate framework microflowers with enhanced supercapacitor and electrocatalytic performances
Novel zeolitic imidazolate framework-67 (ZIF-67) microflowers were synthesized by a quick and simple method without using any template or surfactant.
Europium( iii )–β-diketonate complex-containing nanohybrid luminescent pH detector
In this work, by loading an Eu(3+)-β-diketonate complex into LAPONITE®, we report an organic-inorganic hybrid pH detection system Eu(3+)(TTA)n@Lap that is valid under acid conditions, which can serve as highly robust, reliable, rapid responsive and sensitive fluorescent pH detector. In addition, this hybrid pH detecto…

We report the front-illuminated ultraviolet photodetectors based on TiO 2 nanotube arrays with efficient photodetecting activities.
SOFC Stack and System Development at Forschungszentrum Jülich
Long-term stable and robust stack technology is a pre-requisite for a successful implementation of SOFC in the market and so it is one of the main issues in SOFC development. Also bigger stacks are desirable for systems with increased power output. Progress in stack and systems development is illustrated. Enhanced the…

Coupling of chromophores with exactly opposite luminescence behaviours in mesostructured organosilicas for high-efficiency multicolour emission
RhB), which enables fine-tuning of ACQ@AIE-PMO emissions over the entire visible spectrum in the solid and film states. Significantly, high-quality white light is achieved with CIE coordinates of (0.32, 0.33) and a quantum yield of up to 49.6%. Because of their high stability and solution processability, the ACQ@AIE-P…
Making a commercial carbon fiber cloth having comparable capacitances to carbon nanotubes and graphene in supercapacitors through a “top-down” approach
A "top-down" and scalable approach for processing carbon fiber cloth (CFC) into flexible and all-carbon electrodes with remarkable areal capacity and cyclic stability was developed. CFC is commercially available in large quantities but its use as an electrode material in supercapacitors is not satisfactory. The approa…
Role of lattice oxygen in oxidative steam reforming of toluene as a tar model compound over Ni/La 0.8 Sr 0.2 AlO 3 catalyst
High catalytic performance of Ni/La 0.8 Sr 0.2 AlO 3 catalyst due to high amount of mobile lattice oxygen which favors direct partial oxidation of toluene while gas-phase oxygen favors complete oxidation. Both oxygen species actively oxidize coke deposited on catalyst surface, conferring coking resistance.
