The present study was designed to exploit optimum lipophilicity and high water-exchange rate (k(ex)) on low molecular weight Gd(III) complexes to generate high bound relaxivity (r(1)(b)), upon binding to the lipophilic site of human serum albumin (HSA). Two new carbon backbone modified TTDA (3,6,10-tri(carboxymethyl)-…
BULLETIN OF CHEMICAL REACTION ENGINEERING & CATALYSIS journal is an international electronic journal published by Department of Chemical Engineering, Diponegoro University and Masyarakat Katalis Indonesia - Indonesian Catalyst Society (MKICS).
Transparent conducting films were prepared by using non-functionalized, non-oxidized graphene nanoribbons. Two different dispersion methods were compared. The produced films show sheet resistance as low as 800 Ω/sq when the transmittance at 550 nm is 78%. The performance of the films were close to the entry level for…
Different amine-functionalized mesoporous zirconia were prepared by a co-condensation method using silane [aminopropyltrimethoxysilane (APTES), N -(2 amino ethyl)-3-amino propyl trimethoxy silane (AAPTMS), and 3-[2-(2-amino ethyl amino) ethyl amino] propyl trimethoxy silane (AEPTMS)] and zirconium butoxide. The materi…
Periodic local M\o{}ller-Plesset second-order perturbation theory (MP2) is applied to investigate the structural and energetic properties of the cubic and hexagonal polymorphs of boron nitride. While the Hartree-Fock (HF) solution significantly underbinds both systems and energetically favors $h$-BN, the post-HF corre…

Paramagnetic chemical exchange saturation transfer (PARACEST) contrast agents are under development for biological target identification by magnetic resonance imaging. Image contrast associated with PARACEST agents can be generated by radiofrequency irradiation of the chemically shifted protons bound to a PARACEST con…
A binary gene expression system using the yeast GAL4 DNA-binding protein and the upstream activating sequence (UAS) of galactose-driven yeast genes is an established and powerful tool for the analysis of gene function. However, in the domesticated silkworm, Bombyx mori, this system has been limited in its utility by t…
The wavelength dependent scattering cross sections of self-assembled silver nanoparticle clusters of known size (n) were measured on five different wavelength channels between 427 and 510 nm through correlation of multispectral imaging and scanning electron microscopy. A multivariate statistical analysis of the spectr…
Abstract Well‐defined amphiphilic PLA ‐b‐ PMPC diblock copolymers were synthesized. Bimimetic micelles were prepared and applied for release of anti‐cancer drugs (DOX). TEM and DLS analysis revealed a regular spherical shape with small diameter (less than 50 nm) of the micelle. The biocompatibility of PLA ‐b‐ PMPC mic…
In this work, the use of a ZnO-nanowire (NW)-based heterojunction array structure for application to UV sensors is proposed. Nano-heterojunction arrays (NHAs) were formed via the oblique-angle sputtering deposition of p-type tin monoxide onto vertically aligned ZnO-NWs grown by hydrothermal growth (HTG). The current d…
One-dimensional nanostructures are ideal building blocks for functional nanoscale assembly. Peptide-based nanofibers have great potential in building smart hierarchical structures due to their tunable structures at the single residue level and their ability to reconfigure themselves in response to environmental stimul…
A new, fast, and efficient computational protocol for the accurate calculation of singlet-triplet magnetic splittings in organic diradicals is tested and validated. This procedure essentially consists of three steps: the adoption of modified virtual orbitals (MVO) and a mixed variational-perturbational approach (CSPA)…
The present study examines the role of conductive polymer poly( o -phenylenediamine) in corrosion inhibition and its antibacterial activity against bacterial biofilm ( Bacillus cereus ACE4) on aluminum 2024 aeronautical alloy (AA 2024). Poly( o -phenylenediamine) (PoPD) was successfully electropolymerized by cyclic vo…
We report a detailed study of ultrafast exciton dephasing processes in semiconducting single-walled carbon nanotubes employing a sample highly enriched in a single tube species, the (6,5) tube. Systematic measurements of femtosecond pump-probe, two-pulse photon echo, and three-pulse photon echo peak shift over a broad…
The purpose of this paper is to review recent work on composite materials based on recycled thermoplastics and glass fibres (GFs). The high collection and separation cost of plastics waste, and the legislative push to increase recycling rates, require the inclusion of increasing proportions of low‐quality plastic wast…
A highly sensitive (metal/nanostructure silicon /metal) photodiode has been fabricated from rapid thermal oxidation (RTO) and rapid thermal annealing (RTA) processes,Of nanostructures porous silicon prepared by laser assisted etching . Photoresponse was investigated in the wavelength rang of (400-850nm) . A responsivi…
One of the major questions in a catalytically enhanced NaAlH 4 system used for hydrogen storage that remains is where catalysts like Ti/Ce reside and present as what form improving the kinetics and reversible hydrogen storage performance. In the present study, by directly introducing Ce−Al species with a structure of…
PII proteins are one of the most widely distributed signal transduction proteins in Nature, being ubiquitous in bacteria, archaea and plants. They act by protein-protein interaction to control the activities of a wide range of enzymes, transcription factors and transport proteins, the great majority of which are invol…
This paper reports the texturing behavior of hexagonal boron nitride ( h ‐BN) ceramics prepared by slip casting, followed by spark plasma sintering, using either irregularly shaped or plate‐like h ‐BN as the starting materials. In this study, well‐dispersed h ‐BN ethanol‐based suspensions with 30 vol% solid loading we…
