Dynamically engineering the interfacial interaction of nanoparticles has emerged as a new approach for bottom-up fabrication of smart systems to tailor molecular diffusion and controlled release. Janus zwitterionic nanoplates are reported that can be switched between a locked and unlocked state at interfaces upon chan…
Abstract In recent years, ternary transition metal oxides (TTMOs), especially spinel type TTMOs have attracted widespread attention as promising candidates for electrode materials. Among all of the popular TTMOs, MgCo 2 O 4 is an outstanding one, owing to its superior theoretical capacitance. In this work, MgCo 2 O 4…
This work analyses the potential of hybrid solar thermoelectric photovoltaic generators (HSTEPVGs) through evaluating their efficiency in converting solar power into electricity for a system consisting of a PV cell placed directly on top of a thermoelectric generator. A theoretical model for terrestrial application wh…
We report the fabrication of a novel and highly active nanocatalyst system comprising electrospun carbon nanofiber (CNF)-supported ruthenium nanoparticles (NPs) (Ru@CNF), which can reproducibly be prepared by the ozone-assisted atomic layer deposition (ALD) of Ru NPs on electrospun CNFs. Polyacrylonitrile (PAN) was el…
Abstract The combination of lanthanoid nitrates with 18‐crown‐6 (18‐c‐6) and tetrahalocatecholate (X 4 Cat 2− , X=Cl, Br) ligands has afforded two compound series [Ln(18‐c‐6)(X 4 Cat)(NO 3 )] ⋅ MeCN (X=Cl, 1‐Ln ; X=Br, 2‐Ln ; Ln=La, Ce, Nd, Gd, Tb, Dy). The 18‐c‐6 ligands occupy equatorial positions of a distorted sph…
The metastable 1$T$ polymorph of NbSe${}_{2}$ was recently successfully synthesized in monolayer form. The observation of a superlattice and insulating behavior suggests an analogy with 1$T$-TaS${}_{2}$, an extensively investigated system known for its complex phase diagram that has recently been suggested to realize…
Abstract Over the centuries, scientists and engineers have been fascinated by the directional transport of water on the peristome of pitcher plant. Through experimental investigation and theoretical analysis, here we reveal the more complex picture of droplet transport on this peculiar natural surface. First, we demon…
Abstract This paper reports body heat harvesting and refrigeration effects based on a flexible thermoelectric (TE) system made of rigid inorganic bulk materials. The TE device itself is integrated with small segments that consist of Bakelite holders containing the inorganic bulk TE elements. These holders are connecte…
Asymmetric functionality and directional interactions, which are characteristic of noncentrosymmetric particles, such as Janus particles, present an opportunity to encode particles with properties, but also a great synthetic challenge. Here, we exploit the chemical anisotropy of proteins, and the versatile chemistry o…
Abstract Plasmon‐induced hot carriers have vast potential for light‐triggered high‐efficiency carrier generation and extraction, which can overcome the optical band gap limit of conventional semiconductor‐based optoelectronic devices. Here, it is demonstrated that Au/TiO 2 dumbbell nanostructures assembled on a thin A…
As a typical class of Zintl thermoelectrics, AB 2 C 2 (A = Eu, Yb, Ba, Ca, Mg; B = Zn, Cd, Mg, and C = Sb, Bi) compounds have shown a superior thermoelectric performance, largely stemming from the existence of multiple transporting bands in both conduction types. Being similar to many III–V and elemental semiconductor…
The mitigation of cold-start emissions involves the development of passive NOx adsorbers (PNA) systems that store NOx at low temperature, being designed to release the trapped NOx at higher temperatures, where downstream NOx reduction catalysts are efficient. Pd-based zeolites (BEA, SSZ-13) with different SAR (Si-to-A…
The development of protein-based hydrogels for tissue engineering applications is often limited by their mechanical properties. Herein, we present the facile fabrication of tough regenerated silk fibroin (RSF)/graphene oxide (GO) nanocomposite hydrogels by a photochemical cross-linking method. The RSF/GO composite hyd…
As a new atomically layered, two-dimensional material, tin (IV) diselenide (SnSe2) has attracted extensive attention due to its compelling application in electronics and optoelectronics. However, the great challenge of impurities and the preparation of high-quality ultrathin SnSe2 nanoflakes has hindered far-reaching…
Thermoelectric technology has the ability to convert heat directly into electricity and vice versa. With the rapid growth of portable and wearable electronics and miniature devices, the self-powered and maintenance of free thermoelectric energy harvester is highly desired as a potential power supply. Thin film thermoe…
We use spin-polarized scanning tunneling microscopy to demonstrate that Ho atoms on magnesium oxide exhibit a coercive field of more than 8 T and magnetic bistability for many minutes, both at 35 K. The first spontaneous magnetization reversal events are recorded at 45 K, for which the metastable state relaxes in an e…
In this work, the effect of flame spraying parameters on physical, structural and microstructural characteristics of Al2O3 - 13 wt.% TiO2 (AT-13) coatings were studied. NiCrAl and AT-13 feedstock powders were used for spraying a bond coat (BC) and a top coat (TC), respectively, onto a 7075 aluminum alloy substrate. Th…
A one-pot electrosynthesis platform is reported for fabrication of Y3+ doped iron oxide nanoparticles (Y-IONPs). In this procedure, Y-IONPs are electro-deposited from an additive-free aqueous solution of iron(III) nitrate, iron(II) chloride and yttrium chloride. The analysis data provided by X-ray diffraction (XRD), f…
Ion irradiation of KTaO3 has been performed to investigate the evolution of irradiation damage with and without significant electronic energy deposition. Damage accumulation under irradiation with 2 MeV Au ions follows a direct-impact/defect-stimulated model, and occurs more rapidly than in SrTiO3 under similar condit…
Analyses of a series of xYSZ materials, where x varies from 1 to 15%, have been carried out both in powder form and after sintering to functional materials, namely ion-conducting ceramics for use in SOFC fuel cells. XRD analyses showed that the particles were in the cubic structure confirming the stabilization of this…
