TeO2-nanostructured sensors are seldom reported compared to other metal oxide semiconductor materials such as ZnO, In2O3, TiO2, Ga2O3, etc. TeO2/CuO core-shell nanorods were fabricated by thermal evaporation of Te powder followed by sputter deposition of CuO. Scanning electron microscopy and X-ray diffraction showed t…
The purpose of this review is to gather the current background in materials development and provide the reader with an accurate image of today’s knowledge regarding the stability of dye-sensitized solar cells. This contribution highlights the literature from the 1970s to the present day on nanostructured TiO2, dye, Pt…
This perspective proposes principles to identify nanohybrids with novel properties relevant to nano EHS research, and discusses specific challenges for EHS research on these materials.
Sodium-ion batteries have attracted considerable interest as an alternative to lithium-ion batteries for electric storage applications because of the low cost and natural abundance of sodium resources. The materials with an open framework are highly desired for Na-ion insertion/extraction. Here we report on the first…
We report high-quality GaN crystals grown directly on graphene layers without a buffer layer by metal–organic chemical vapour deposition.
This paper presents the control system design for a piezoelectric actuator (PEA) for a high-speed trajectory scanning application. First nonlinear hysteresis is compensated for by using the Maxwell resistive capacitor model. Then the linear dynamics of the hysteresis-compensated piezoelectric actuator are identified.…
Mesoporous γ-Al 2 O 3 with high surface area (159 m 2 /g) is prepared via a precipitation method. The as-synthesized Al 2 O 3 exhibits optical absorption ability in the ultraviolet region and is used as the active component to be combined with g-C 3 N 4 to form effective heterostructured photocatalysts. This heterojun…
The present work is a short review of our recent studies on PhotoFuelCells, that is, photoelectrochemical cells which consume a fuel to produce electricity or hydrogen, and presents some unpublished data concerning both electricity and hydrogen production. PhotoFuelCells have been constructed using nanoparticulate tit…

A mechanistic investigation of the efficient cleavage of C–O bond of diphenyl ether by hydrogenolysis and hydrolysis was attempted via theoretical calculations in association with experimental analysis.
Interconnected or crossed magnetic nanowire networks have been fabricated by electrodeposition into a polycarbonate template with crossed cylindrical nanopores oriented ±30° with respect to the surface normal. Tailor-made nanoporous polymer membranes have been designed by performing a double energetic heavy ion irradi…
Abstract. Mineral dust supplied to remote ocean regions stimulates phytoplankton growth through delivery of micronutrients, notably iron (Fe). Although attention is usually paid to Fe (hydr)oxides as major sources of available Fe, Fe-bearing clay minerals are typically the dominant phase in mineral dust. The mineralog…
Protection of metal nanoparticles from agglomeration is critical for their functions and applications. The conventional method for enhancing their stability is to cover them with passivation layers to prevent direct contact. However, the presence of a protective shell blocks exposure of the metal species to reactants,…
The modification of bandgap of TiO2 was intensively studied for decades to improve its visible light absorbance efficiency. The practical application potential of TiO2 as photocatalysts for water splitting and water purification has motivated enduring experimental and theoretical research of the doping effects in bulk…
Hierarchical ZSM-5 catalysts were prepared by desilication with different NaOH concentrations. Their structure and acidity were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), N 2 adsorption and desorption, ammonia temperature-programmed desorption (NH 3 -TPD), pyridine Fourier transf…
The phase diagram of the Li–Mn–Ni-oxide pseudoternary system 1 was used as a starting point to understand the influence of transition metal composition and lithium content on the structures and electrochemistry of materials with compositions: Li 1+ x (Ni y Mn 1– y ) 1– x O 2 ( y = 0.2, 0.33, 0.4, 0.5, 0.6, and 0.7, 0…
A low scaling quantum chemistry program, called LSQC, is described in this article. This version includes two linear scaling methods, generalized energy‐based fragmentation (GEBF) approach and cluster‐in‐molecule (CIM) approach. In the GEBF approach, a variety of electron structure methods (including ab initio and den…
Oxidative damage to DNA and hole transport between nucleobases in oxidized DNA are important processes in lesion formation for which surprisingly poor thermodynamic data exist, the relative ease of oxidizing the four nucleobases being one such example. Theoretical simulations of radiation damage and charge transport i…
This review aims to provide an update on the development involving dielectric/organic semiconductor (OSC) interfaces for the realization of biofunctional organic field-effect transistors (OFETs). Specific focus is given on biointerfaces and recent technological approaches where biological materials serve as interlayer…
Recently, a new family of lithium-rich antiperovskites, Li 3 OA (A = halogen), which presents superionic conductivity, emerged as a promising both safe and commercially applicable solid electrolyte for lithium ion batteries. In this paper we employed classical atomistic quasi-static calculations to obtain the concentr…
