This work is related to the removal of tritiated water and radioactive iodine from off-gases released during spent nuclear fuel reprocessing. Specifically, it is focused on the adsorption equilibrium of water on reduced silver mordenite (Ag 0 Z), which is the state-of-art solid adsorbent for iodine retention in the of…
We address the issue of achieving high oxide ion conductivity at low temperatures $(\ensuremath{\le}500{\phantom{\rule{0.16em}{0ex}}}^{\ensuremath{\circ}}\mathrm{C})$ in stable electrolytes for solid oxide fuel cell (SOFC) techonology. We report here a high oxide ion conductivity $(\ensuremath{\sim}{10}^{\ensuremath{-…
The objective of this study is to compare the spinnability, morphology, structure, mechanical properties, and cell compatibility of the silk fibroin nanofiber nonwoven electrospun fabrics using aqueous (AQ) solution and formic acid (FA) solution. The lower limit concentration was 5 wt% and 3 wt% of AQ solution and FA…
Molybdenum disulfide (MoS2) is a promising potential replacement for Si in future microelectronic devices. Integration in electronic devices will likely involve the growth or transfer of large-area MoS2 films onto substrates and subsequent isolation of devices. In this paper, the effect of ion implantation on the elec…
This paper presents an extensive study of the structural, magnetic, and thermodynamic properties of the heterometallic ludwigite ${\mathrm{Co}}_{4.76}{\mathrm{Al}}_{1.24}{({\mathrm{O}}_{2}{\mathrm{BO}}_{3})}_{2}$. This material orders ferrimagnetically at 57 K. Despite the fact that, in ${\mathrm{Co}}_{4.76}{\mathrm{A…
Abstract The use of first order magnetocaloric materials (FOM’s) in magnetic cycles is of interest for the development of efficient magnetic heat pumps. FOM’s present promising magnetocaloric properties; however, hysteresis reduces the reversible adiabatic temperature change ( <mml:math xmlns:mml="http://www.w3.org/19…
A series of novel BODIPY dyes has been prepared through the introduction of an N-bridged annulated meso-phenyl ring at one of the β-positions of the BODIPY core. An unusual blueshift of the main spectral bands is observed, since the fusion of a meso-substituent results in a marked relative destabilization of the LUMO.…
Transparent anodes are indispensable components for optoelectronic devices. Two-dimensional (2D) materials are attracting increasing research interest due to their unique properties and promising applications. In order to design novel transparent anodes, we investigated the electronic, optical, and electrical properti…
Antimony(III) alkoxide cages were designed as building blocks for predictable supramolecular self-assembly. Supramolecular synthons featuring two Sb···O secondary bonding interactions (SBIs), each SBI stronger than 30 kJ/mol, were used to drive the formation of the supramolecular architectures. Judicious choice of pen…
ABSTRACT Thermoplastic polydimethylsiloxane (PDMS) containing l ‐phenylalanine was synthesized by the liquid‐phase synthesis method with an Fmoc‐protected amino acid and by the condensation polymerization. In order to investigate the mechanical and the thermoplastic properties of the PDMS with l ‐phenylalanine, the te…
The potential energy balance of the sawing logs for Eucalyptus lumber production was determined. Eucalyptus grandis logs (n = 10) were sawn with a band saw, and the planks were re-sawed with a circular saw. The sawing yield was calculated with the volumes of logs, lumbers, and wastes. The consumption of electric energ…
Scalable fabrication of two-dimensional materials-based devices with consistent characteristics remains a significant impediment in the field. Here, we report on as-grown monolayer MoS2 metal-semiconductor-metal photodetectors produced using a CVD process which results in self-contacted two-dimensional material-based…
Microfibrillated cellulose (MFC) and nanofibrillated cellulose (NFC) isolated from cotton linters were evaluated as a strength additive in unbleached kraft paper and compared with semi-empirical and mechanistic models. The z-directional tensile strength was enhanced due to NFC and MFC. The tensile energy absorption (T…
Highly sensitive labeled detection of Echinococcus granulosus using colloidal quantum dots (QDs) based on a porous silicon Bragg mirror sensor are demonstrated. Rabbit anti-p38 labeled CdSe/ZnS QDs was infiltrated in porous silicon pores immobilized Egp38 antigen. QD-antibodies are specifically bound to antigens linke…
Spider silk proteins comprise a repetitive core domain with polyalanine and glycine/proline-rich stretches flanked by highly conserved nonrepetitive N- and C-terminal domains. The termini are responsive to assembly triggers, sensing changes in the ionic (H +, phosphate) and mechanical (shear stress) environment along…
The annealing behavior of poly(propylene glycol) (PPG, M w = 4000 g/mol) incorporated into the nanoporous aluminum oxide (AAO) membranes of different pore diameter was investigated by broadband dielectric spectroscopy (BDS) and differential scanning calorimetry (DSC). The presence of two subsets of molecules of differ…
Co-oligomers composed of two 3,4-ethylenedioxythiophene (EDOT) units and two or three 3,4-propylenedioxythiophene (ProDOT) units, i.e., 2E2P Et and 2E3P Et, were newly synthesized together with the ProDOT trimer 3P Me . On the basis of cyclic voltammetry, the gaps between the first and second oxidation potentials (Δ E…
Abstract Ln 2 Ti 2 O 7 (Ln=Y and Gd) pyrochlore glass‐ceramics have been fabricated successfully via internal crystallization. Subsequently, the phase evolution from Ln 2 Ti 2 O 7 pyrochlores to Ln 0.5 U 0.5 Ti 2 O 6 brannerites in glass with uranium (U) substitutions on the Ln‐site of Ln 2 Ti 2 O 7 has been investiga…
In the present work, we report the hydrothermal synthesis of NiCo2O4/Single walled carbon nanotubes (SWNTs) nanocomposites for supercapacitor applications. The SWNTs provided the conductive network and favored the growth of NiCo2O4 nanoparticles on its surface to facilitate the collection and transportation of electro…
Paraffin-based actuators can deliver large actuation strokes and high actuation stress, but often suffer from a low response rate and leaking problems. Here, we report a new paraffin/metal hybrid actuator, which was fabricated by infiltrating nanoporous gold with paraffin. It exhibits a fast actuation rate owing to th…
