The recent studies of thermal transport in suspended, supported, and encased graphene just began to uncover the richness of two-dimensional phonon physics, which is relevant to the performance and reliability of graphene-based functional materials and devices. Among the outstanding questions are the exact causes of th…
We study the valley-dependent magnetic and transport properties of massive Dirac fermions in multivalley systems such as transition metal dichalcogenides. The asymmetry of the zeroth Landau level between valleys and the enhanced magnetic susceptibility can be attributed to the different orbital magnetic moment tied wi…
, 3d-4f and 4f compounds demonstrate an enormous variety in their structure and bonding. This review examines the synthetic strategies to these molecules and their magnetic properties, whilst trying to assess these ligands' suitability towards new SMMs and magnetic refrigerants.
Molecules exhibiting bistability have been proposed as elementary binary units (bits) for information storage, potentially enabling fast and efficient computing. In particular, transition metal complexes can display magnetic bistability via either spin-crossover or single-molecule magnet behavior. We now show that the…
With the emergence of flexible/stretchable electronic devices, flexible supercapacitors (SCs) have attracted widespread interest in developing lightweight, thin, elastic and efficient portable/wearable energy storage devices that show promising applications in hybrid electric vehicles, uninterruptible power supplies a…
Due to the promising applications in low-cost and high performance photovoltaic and thermoelectric devices, there has been a booming development of syntheses of colloidal I–III–VI2 and I2–II–IV–VI4 (I = Cu, Ag; II = Zn, Cd; III = Al, Ga, In; IV = Ge, Sn; VI = S, Se, Te) nanocrystals during the past ten years. In this…
Reactive dissolution and its effects on electrical conduction, morphological change and chemical transformation in thin films of Mg, AZ31B Mg alloy, Zn, Fe, W, and Mo in de‐ionized (DI) water and simulated body fluids (Hanks’ solution pH 5–8) are systematically studied, to assess the potential for use of these metals…
By embedding four-rod resonators inside double-split ring resonators superlattice, a planar composite metamaterial possessing tripod plasmonic resonances is fabricated. Double Fano resonances are observed where a common subradiant driven oscillator is coupled with two superradiant oscillators. As a classical analogue…

In the framework of the increasing need for metal‐doped polymer materials for inertial confinement fusion targets, we report the preparation of low‐density titanium‐containing materials. For this purpose, we developed a new monomer based on hydroxyl and oxime chelation: Ti3(5‐vinylsalicylaldoximato)2(Oi‐Pr)8. We repor…
New methods of producing small quantities of exotic alloys from immiscible metals (and elements in general) are described with two examples: An alloy of aluminium with silver and one of aluminium with tungsten. There is no limit to the number of components that can form special alloys by this method and their applicat…
Graphene electrodes provide a suitable alternative to metal contacts in molecular conduction nanojunctions. Here, we propose to use graphene electrodes as a platform for effective photon assisted tunneling through molecular conduction nanojunctions. We predict dramatic increasing currents evaluated at side-band energi…
The self-assembly and construction of specific Schiff base nickel complexes are important in the exploration of new functional materials. In the present work, in the presence of thiocyanate ligands, two mononuclear Schiff base nickel(II) complexes, [NiL1(NCS)] (1) and [Ni(L2)2] (2) (L1 = 2-bromo-6-[ (2-dimethylaminoet…
Pulmonary sclerosing hemangioma is an uncommon tumor, thought to be a benign neoplasm. Pericardial cysts are also uncommon benign abnormalities, most often found incidentally on chest radiography. We describe the case of a 51-year-old woman in whom both lesions were incidentially detected on a routine chest radiograph…
The commercial vehicle industry has seen regulations create new requirements over the last few years. Reductions to stopping distance, improvements to vehicle emissions, and the overall need for lighter weight vehicles has caused the commercial vehicle industry to look for new solutions to meet these needs. One such s…
We demonstrate a variety of gradient index (GRIN) devices for both freely propagating terahertz waves and terahertz surface waves. As a specific example of a static GRIN optics we experimentally investigated and measured the optical properties of a GRIN beam deflector. We measured a maximum deflection angle of 6 deg.…
The AISI 306L stainless steel implanted with nitrogen has been characterized by means of electrochemical and mechanical measurements. Implanted samples used saturation doses of 6×1015, 2.03×1016 and 1.6×1017 ions N2×cm-2 at an acceleration voltage of 3.6 MeV. Implanted and non-implanted samples were compared in order…
Solid oxide fuel cell (SOFC) systems are the most advanced power generation system with the highest thermal efficiency. The current trend of research on the SOFC systems is focused on multikilowatt scale systems, which require either internal reforming within the stack or a compact external reformer. Even if the inter…
In our earlier work1, we have developed an analytical current transport model of a p-channel Tunnel Field Effect Transistor (T-FET) made from 2D atomically thick Graphene Nanoribbon (GNR). Considering drain-source voltage (VDS), gate-source voltage (VGS), carrier mobility (μ) and top gate dielectric (tOX), the model d…
Graphene’s unique mechanical, electrical, and thermal properties have made it a very attractive material desired for use in future technologies. Over the recent years, there have been many breakthroughs in research on graphene. Recently, the focus of the latest research has shifted towards scaling graphene production…
