Our group is interested in applying supramolecular host systems as catalysts for challenging transformations. Although a variety of supramolecular containers has been described in literature, their use as reaction chambers is still underexplored. We herein describe our first steps in this exciting interdisciplinary fi…
Synthesis and characterization of X-ray shielding thermoplastic polyurethane elastomers which are capable of blocking harmful radiation emitted by various sources are reported. X-ray shielding capability was generated in the polymer by covalently binding iodine atoms in a monomer and polymerizing it with other monomer…
This article gives a brief overview of the development of vanadium alloys as structural materials for fast and fusion reactors in future. The most important properties of vanadium alloys are considered with respect to the properties of austenitic and ferritic-martensitic steels. Vanadium is sufficiently spread in natu…
The photoelectrochemical properties of (In,Ga)N nanowire photoanodes are investigated using H 2 O 2 as a hole scavenger to prevent photocorrosion. Under simulated solar illumination, In 0.16 Ga 0.84 N nanowires grown by plasma-assisted molecular beam epitaxy show a high photocurrent of 2.7 mA/cm 2 at 1.2 V vs reversib…
In this work we study the diffusion–adsorption process in porous media and analyze the effect that the irregular geometry of the pores has on the efficiency of two types of adsorption processes: (a) when there is a net flux along the pore and (b) when the pore is completely saturated. In the first case, we measured th…
The effects of increasing the driving forces for a 1-D assembly of nanoparticles onto a surface are investigated with experimental results and models. Modifications, which take into account not only the particle-particle interactions but also particle-surface interactions, to previously established extended random seq…
The influence of pressure on the structural and elastic properties of ScM ([Formula: see text], Cu, Ag, Hg) compounds has been investigated by using ab initio approach pseudopotential plane-wave method based on the density functional theory within the generalized gradient approximation (GGA). The optical properties ha…
Background: Dehydrozingerone is a biosynthetic intermediate and structural analog of curcumin. It is a flavoring ingredient and has antioxidant and antimutagenic properties. Dehydrozingerone can be efficiently synthesized from vanillin and acetone by cross-aldol (or Claisen-Schmidt) condensation using heterogeneous ba…
Advanced THz setups require high performance optical elements with large numerical apertures and small focal lengths. This is due to the high absorption of humid air and relatively low efficiency of commercially available detectors. Here, we propose a new type of double-sided sub-THz diffractive optical element with s…
We investigated the effect of Ar ion sputtering on the surface electronic structure of indium tin oxide (ITO) using X-ray and ultraviolet photoelectron spectroscopy (XPS and UPS) measurements with increasing Ar ion sputtering time. XPS measurements revealed that surface contamination on ITO was rapidly removed by Ar i…
Electric vehicles are set to become a most attractive alternative transportation mode due to their high efficiency and low emission. Electric vehicles require an efficient energy storage system, e.g. a supercapacitor. Coconut shells have high lignocellulosic content and are not being fully utilized in Indonesia. The l…
The effects of the debinding atmosphere on the properties of sintered reaction-bonded Si 3 N 4 (SRBSN) ceramics prepared by tape casting method were investigated. Si green tape was produced from Si slurry of Si powder, using 11.5 wt% polyvinyl butyral as the organic binder and 35 wt% dioctyl phthalate as the plasticiz…
Density functional theory and nonequilibrium Green's function-based first principle calculations have been performed for an in-depth analysis of infinitely long boron-groupV (N, P, As, and Sb) linear atomic chains (LACs) under tensile stress. The analysis revealed the presence of dative bond among the atoms of LAC, an…
Indonesia has abundant resources of lateritic nickel ore and coal. However, this resource has not been considered as a main raw material in the Indonesian steel industry . Therefore, this study are aimed to investigate several aspects of lateritic nickel intrinsic propertiesand its potency through heat treatment proce…
In the present study, nano-sized cuboid-shaped particles in Mg-Nd-Y are studied by means of Cs-corrected atomic-scale high-angle annular dark-field scanning transmission electron microscopy. The structure of the cuboid-shaped phase is identified to be yttrium (major component) and neodymium atoms in face-centered cubi…
Background: In this review, we summarized the relevance of anisotropic morphologies in the synthesis and applications of metal nanoparticles, including Janus nanoparticles. In recent years, the control over the shape of metal particles has successfully achieved. Non-spherical gold nanoparticles such as rods, wires, cu…
Stenosis of the critical blood vessels, which occurs in a variety of cardiovascular and cerebrovascular diseases, is one of leading causes of death in the world. Vascular stenosis will significantly alter the hemodynamic features in the vessel. Hemodynamic shear stress, one of the most important physical parameters of…
Cellulose nanocrystal-reinforced poly(vinyl alcohol)/silica glass hybrid scaffolds were fabricated using the freeze-drying method. In this study, we develop molecular-level-based hybrid scaffolds with possible bioactivity behavior by adding silica sol–gel. The results showed a highly porous structure and a significant…
This work is a preliminary study with the purpose to find some information about the effectiveness of Ceraflava (CF) extract as inhibitor in 3.5 %NaCl, CF or yellow bees wax from honey farm used as corrosion inhibitor. In particular the purpose of this study is to determine the ability of CF in inhibiting the corrosio…
To precisely model the size dependencies in nanostructures, the surface effect and bulk effect are incorporated. From the physical point of view, size dependencies stem from not only the surface, but also the bulk. The surface energy theory and strain gradient elasticity theory are introduced to characterize the surfa…
