Phosphorus-containing hyperbranched aromatic-aliphatic polyamides are prepared via direct polymerization of triacid (B3) with different diamines (A2), which for improving the processability of aromatic polyamides while keeping exellent thermal and mechanical property. The triacid (B3), tris(2-carboxyethyl)phosphine ox…
A liquid marble is a droplet of liquid coated with microparticles or nanoparticles. A novel method of localized electrochemical deposition (LECD) using liquid marbles and the feasibility of application of this method in additive manufacturing/microrepair is studied. Controllability of the transportation of liquid marb…
Synchrotron-based techniques have had, over the last 30 years, a major and profound effect on the study of complex materials and on environmental science. Their ability to obtain accurate information at the atomic and molecular level on both local and long-range structures, together with the increasing ability to unde…
A new "offset" analogue of the classical [Mn6O2]-core oxime-bridged single-molecule magnets is introduced with a modified stacking arrangement of the [Mn3O] units. Studies of the magnetic properties reveal antiferromagnetic exchange interactions, a spin S = 4 ground state and population of low-lying excited states. Sl…
Research on semiconductor nanowires underlies the development of the miniaturization of laser devices with low cost and low energy consumption. In general, nanowire lasers are made of direct band gap semiconductors, e.g., GaN, ZnO and CdS, and their band-edge emissions are used to achieve optically pumped laser emissi…
In this work, we investigated the structural and magnetic properties of both as-deposited and post-annealed Cu-doped ZnO thin films for better understanding the possible mechanisms of room-temperature ferromagnetism (RT-FM) in ZnO-based diluted magnetic oxides. All of the films have a c-axis-oriented wurtzite structur…
Graphitic-like ZnO layers have been experimentally synthesized on metal substrates over the past few years. Nevertheless, the impact of metal substrates on the structural and electric properties of ZnO is still unclear. Utilizing first-principle calculations with van der Waals correction, we found that the phase trans…
N-(alkyl-substituted) maleimides (RMIs) were proposed as materials useful for the development of a zero-zero-birefringence polymer that exhibits no birefringence. We analyzed the optical and thermal properties of poly(RMI)s, such as the refractive index, birefringence, and glass transition temperature. The characteris…
It has been known that the iodide (I−) anions are necessary for the production of high-quality Au nanoprisms. Based on a previously reported seed-mediated synthesis of triangular gold nanoprisms, herein, we further optimised the synthesis process by varying the concentration of added NaI and seeds, respectively, to ge…
In many materials it remains a challenge to reveal the nature of magnetic correlations, including antiferromagnetism and spin disorder. Revealing the spin structure in magnetic nanoparticles is further complicated by the large incoherent neutron scattering cross section from water adsorbed at the particle surfaces and…
The preparation of nanoporous melamine‐formaldehyde resins by aqueous dispersion polycondensation under oxalic acid catalysis is presented. Multimodal porosity, including micro‐, meso‐, and macropores, is achieved by an interplay of hard‐templating of 12 nm sized silica nanoparticles and phase separation processes, re…
Two as-synthesized meso- and macro-porous siliceous materials (MPSMs), i.e., Al-MCM-41 and SBA-15, were mixed with tobacco to study their effect on tobacco smoke chemistry. A reference cigarette, 3R4F, and a commercial cigarette, Fortuna, containing different percentages of MPSM were smoked in a smoking machine, and t…
Transparent and flexible carbon doped ZnO (C:ZnO) field emission device was successfully fabricated on an arylite substrate. Excellent adhesion of deposited C:ZnO on the flexible substrate was achieved with low sputtering power and Ar flow rate. In the fabricated device, nanostructured C:ZnO and as-deposited thin film…
A dimensionality controlled metal insulator transition in epitaxial [LaNiO3 (d nm)/LaAlO3(2 nm)]10 (100) superlattices (thereafter [d/2]10 SLs) is demonstrated for decreasing LaNiO3 single layer thickness from 4 nm down to 1.2 nm. The [4/2]10 SL shows metallic behavior with positive resistivity temperature coefficient…
Poly(3-hydroxypropionate) (P3HP) is a biodegradable and biocompatible thermoplastic. Previous studies demonstrated that engineered Escherichia coli strains can produce P3HP with supplementation of expensive vitamin B12. The present study examined the production of P3HP from glycerol in the recombinant Klebsiella pneum…
Raman spectroscopy was used to characterize the microstructure of reaction bonded boron carbide ceramics. Compositional and structural gradation in the silicon-doped boron carbide phase (rim), which develops around the parent boron carbide region (core) due to the reaction between silicon and boron carbide, was evalua…
Abstract Single crystals of Pr 3 S 2 Cl 2 [AsS 3 ] were obtained by reacting praseodymium sesquisulfide and trichloride with arsenic and sulfur (molar ratio: 7:4:6:9) in torch‐sealed evacuated silica ampoules at 850 °C for a week and subsequent slow cooling to room temperature. The transparent, pale yellowish green pl…
Photochromic compounds have attracted attention as ophthalmic lenses because of their reversible color modulation upon irradiation with light. However, the efficiency of the photochromism is strongly affected by their surrounding because of the structural changes concomitant with the photochromism, which causes the de…
We report a large enhancement of the Hall mobility of a ZnO film (channel) by simultaneously application of an ultraviolet illumination along with a gate bias in an electric double layer field effect transistor configuration. The effect arises from a synergy between the illumination and the field effect (FE), leading…
Silicon nanocrystals embedded in SiC are studied by spectrophotometry and photoluminescence (PL) spectroscopy. Absorptivities are found to be affected by residual Fabry-Pérot interference arising from measurements of reflection and transmission at locations of different film thickness. Multiple computational and exper…
