A mixture of two triamines, one diamine, 2-formylpyridine and a Zn(II) salt was found to self-sort, cleanly producing a mixture of three different tetrahedral cages. Each cage bound one of three guests selectively. These guests could be released in a specific sequence following the addition of 4-methoxyaniline, which…
Abstract This is a review of the elastic behaviour and pressure (P)-induced structural evolution of zeolites and presents a comparative analysis of the deformation mechanisms of the Si/Al-framework and the rearrangement of the extra-framework species in response to applied pressure. The interaction betweenP-transmitti…
The rise of plasmonic metamaterials in recent years has unveiled the possibility of revolutionizing the entire field of optics and photonics, challenging well-established technological limitations and paving the way to innovations at an unprecedented level. To capitalize the disruptive potential of this rising field o…
Photonic and phononic crystals are metamaterials with repeating unit cells that result in internal resonances leading to a range of wave guiding and filtering properties and are opening up new applications such as hyperlenses and superabsorbers. Here we show the first, to our knowledge, 3D colloidal phononic crystal t…
A facile ligand exchange method for dispersing Cu2ZnSnS4 (CZTS) nanocrystals (NCs) in environmentally benign polar solvents, such as ethanol or n-propanol, at high concentrations (up to 200 mg/mL) is demonstrated. This approach has been applied to CZTS nanocrystals synthesized via scalable, noninjection methods to for…
Vertically aligned, free-standing p-Si nanowire arrays of varying lengths are grown on p-Si wafers and coupled with Sn nanoparticles for solar CO2 conversion. These heterojunction wire/Sn arrays increase the production of formate dramatically, by more than 10 and 5 times compared to planar p-Si and wire arrays, respec…
Field confinement at the junction between a biased scanning probe microscope's tip and solid surface enables local probing of various bias-induced transformations, such as polarization switching, ionic motion, and electrochemical reactions. The nanoscale size of the biased region, smaller or comparable to that of feat…
The traditional role of lipids in the generation of lipid-based supramolecular structures has predominantly been to serve as building blocks to support the delivery or stabilization of a molecule or structure. With an introduction to the synthesis of porphyrin-lipid, a porphyrin conjugated to a phospholipid, and the d…
The necessity to externally validate QSAR models is highlighted with example of models stable by cross-validation but not predictive for new chemicals
It is well established that laser cutting or mechanical cutting of nonoriented electrical steel causes structural changes at the cutting edge, which finally affect the magnetic properties. During mechanical cutting, plastic deformation appears in the zone near the cutting edge. On the contrary, laser cutting induces t…
This investigation, studies the dry sliding wear behavior of aluminum (Al) matrix hybrid composites reinforced with rice husk ash (RHA) and silicon carbide (SiC) particulates up to 8% (in equal proportions) fabricated by vortex method. Pin-on disk wear test was carried out for both unreinforced alloy and hybrid compos…
Construction of multifunctional stimuli‐responsive nanosystems intelligently responsive to inner physiological and/or external irradiations based on nanobiotechnology can enable the on‐demand drug release and improved diagnostic imaging to mitigate the side‐effects of anticancer drugs and enhance the diagnostic/therap…
Molecular ferroelectric thin films are highly desirable for their easy and environmentally friendly processing, light weight, and mechanical flexibility. A thin film of imidazolium perchlorate processed from aqueous solution is an excellent molecular ferroelectric with high spontaneous polarization, high Curie tempera…
In this paper, a plasmonic nano-transceiver for wireless communication in the Terahertz Band (0.1-10 THz) is proposed, modeled and analyzed. The nano-transceiver is based on a High Electron Mobility Transistor (HEMT) built with a III-V semiconductor and enhanced with graphene. In transmission, when a voltage is applie…
This study aimed to identify biological contaminants of banana in vitro cultures. We also tested the effect of Zn or ZnO nanoparticles on elimination of some bacterial and fungal contaminants and their influence regeneration. Nine strains of bacterial contaminants (Cellulomonas uda, Cellulomonas flarigena, Corynebacte…
Controlled degradation and transiency of materials is of significant importance in the design and fabrication of degradable and transient biomedical and electronic devices and platforms. Here, the synthesis of programmable biodegradable and transient insulating polymer films is reported, which have sufficient physical…
Noble metal nanocrystals (NCs) enclosed with high-index facets hold a high catalytic activity thanks to the high density of low-coordinated step atoms that they exposed on their surface. Shape-control synthesis of the metal NCs with high-index facets presents a big challenge owing to the high surface energy of the NCs…
The field of thin-film photovoltaics has been recently enriched by the introduction of lead halide perovskites as absorber materials, which allow low-cost synthesis of solar cells with efficiencies exceeding 16%. The exact impact of the perovskite crystal structure and composition on the optoelectronic properties of t…
Nonoxidative cathodically induced graphene (CIG) here incorporates conductive agents for Li4Ti5O12 (LTO) anode materials. The tailored LTO/CIG composite is fabricated by controlled hydrolysis of tetrabutyl titanate in the presence of nonoxidative defect‐free cathodically induced graphene (CIG) and oxalic acid in a mix…
Inhibition of amyloid fibrillation and clearance of amyloid fibrils/plaques are essential for the prevention and treatment of various neurodegenerative disorders involving protein aggregation.
