Excited states in $^{38,40,42}\mathrm{Si}$ nuclei have been studied via in-beam $\ensuremath{\gamma}$-ray spectroscopy with multinucleon removal reactions. Intense radioactive beams of $^{40}\mathrm{S}$ and $^{44}\mathrm{S}$ provided at the new facility of the RIKEN Radioactive Isotope Beam Factory enabled $\ensuremat…
This study reports the novel dry activation for preparing activated carbon with a high specific surface area from rice husks using solid NaOH. Materials were characterized by N 2 adsorption, X-ray diffraction, infrared spectroscopy, and scanning electron microscopy. The effects of mass ratio (1–4) and the activation p…
Nowadays, there is a great interest in the economic success of direct-ethanol fuel cells; however, our atomistic understanding of the designing of stable and low-cost catalysts for the steam reforming of ethanol is still far from satisfactory, in particular due to the large number of undesirable intermediates. In this…
Abstract Grafting six fluorene units to a benzene ring generates a new highly twisted core of hexakis(fluoren‐2‐yl)benzene. Based on the new core, six‐arm star‐shaped oligofluorenes from the first generation T1 to third generation T3 are constructed. Their thermal, photophysical, and electrochemical properties are stu…
The synthesis and characterisation of the Mn-based analogue of the MIL-100 framework is reported. The title compound is synthesised from a methanolic solution of trimesic acid and manganese(II) nitrate in very short reaction times. During the reaction, the Mn2+ ions are oxidized in situ to Mn3+ ions. The obtained MOF…
Abstract Nanocatalysis has been a growing field over the past few decades with significant developments in understanding the surface properties of nanocatalysts. With recent advances in synthetic methods, size, shape and composition of the nanoparticles can be controlled in a well defined manner which facilitates achi…
The design of bioactive materials allows tailored studies probing cell-biomaterial interactions, however, relatively few studies have examined the effects of ligand density and material stiffness on neurite growth in three-dimensions. Elastin-like proteins (ELPs) have been designed with modular bioactive and structura…

We report the discovery of a pressure-induced heavy fermion superconductivity in a nonmagnetic orbital ordering state in the cubic compound PrTi(2)Al(20). In particular, we found that the transition temperature and the effective mass associated with the superconductivity are dramatically enhanced as the system approac…
A new polymeric semiconductor, PDPPDTSE, is reported which is composed of a diketopyrrolopyrrole moiety and selenophenylene vinylene selenophene, with a high field-effect mobility achieved through intermolecular donor-acceptor interactions. The field-effect mobility of OFET devices based on PDPPDTSE by spin-casting is…
Recent genome-wide association studies indicate that a simple alteration of Leucine-rich repeat kinase 2 (LRRK2) gene expression may contribute to the etiology of sporadic Parkinson's disease (PD). However, the expression and regulation of LRRK2 protein in the sporadic PD brains remain to be determined. Here, we found…
The metal-organic coordination polymers at the nanoscale have emerged as attractive nanomaterials due to their tunable nature. In this work, we for the first time prepared an adenine-based lanthanide coordination polymer nanoparticle (CPNP) with fluorescence sensing function. This kind of CPNP was composed of adenine,…
A reduction of the bandgap and an enhancement of the charge transport properties of a LBG polymer (PBDTT-DPP) can be achieved simultaneously by changing the sulfur atoms on the DPP unit to selenium atoms. The newly designed polymer, PBDTT-SeDPP (Eg = 1.38 eV), shows excellent photovoltaic performance in single junctio…
In this tutorial review we highlight fundamental aspects of the physics underpinning the science of photonic crystals, provide insight into building-block assembly routes to the fabrication of different photonic crystal structures and compositions, discuss their properties and describe how these relate to function, an…
We report a ratiometric fluorescent sensor based on monochlorinated BODIPY for highly selective detection of glutathione (GSH) over cysteine (Cys)/homocysteine (Hcy). The chlorine of the monochlorinated BODIPY can be rapidly replaced by thiolates of biothiols through thiol-halogen nucleophilic substitution. The amino…

BACKGROUND: Many efforts have been recently devoted to design, investigate and synthesize biocompatible, biodegradable polymers for applications in medicine for either the fabrication of biodegradable devices or as drug delivery systems. Many of them consist of condensation of polymers having incorporated peptide link…
Nano popcorn: a new formation mechanism for the synthesis of hollow metal oxide nanoparticles through a melt fracture mechanism. The hollow nanoparticles are formed via brittle fracture following the generation of tensile stresses arising due to liquid-phase thermal expansion of a low melting point core metal. The pro…
A novel type of calcium phosphate and iron(III) scale inhibitor acrylic acid‐allylpolyethoxy carboxylate AA‐APELn (ALn) was synthesized. The observation shows that the adsorption of the ALn copolymer on the crystal surface caused deformation of calcium phosphate crystal morphology. Furthermore, both calcium phosphate…
