Strong dependence of fluorescence quenching on the transition metal in layered transition metal dichalcogenide nanoflakes for nucleic acid detection
In recent years, the application of transition metal dichalcogenides for the development of biosensors has been receiving widespread attention from researchers, as demonstrated by the surge in studies present in the field. While different transition metal dichalcogenide materials have been employed for the fabrication…
Effect of Water and [Emim][OAc] as Plasticizer on Gelatinization of Starch
As the depletion of petroleum source and environmental concerns been arises, a new polymer defined as biodegradable material had been extensively study in order to replace the synthetic one. Starch is one of natural materials that been used for producing biodegradable materials. Through gelatinization process, native…
The determination of cystatin C in serum based on label-free and near-infrared light emitted PbS@BSA QDs
In this paper, near infrared light emitting PbS@BSA QDs were synthesized and applied to the biosensing of cystatin C. Furthermore, PbS@BSA QDs could serve as an "optical window" for the bioimaging of cystatin C with high selectivity in the solution containing 50% serum samples.
Preparation, Characterization and in Vitro Evaluation of the Antitumor Activity of the Biologically Synthesized Silver Nanoparticles
This study was concentrated on the biosynthesis of silver nanoparticles from Penicillium aurantiogresium (IMI 89372) with a focus on its cytotoxicity in MCF-7 and MCT cancer cell lines as well as Vero (normal) cell line that was assessed by crystal violet assay after treatment with various concentrations (0.44 – 145 μ…
The microwave-assisted solvothermal synthesis of a novel β-ketoenamine-linked conjugated microporous polymer for supercapacitors
A novel β-ketoenamine-linked conjugated microporous polymer was synthesized via a facile microwave-assisted condensation, which showed high capacitance (252 F g −1 at 1 A g −1 ), excellent cycling stability and long cycle life for energy storages.
Elucidating dominant pathways of the nano-particle self-assembly process
Self-assembly processes play a key role in the fabrication of functional nano-structures with widespread application in drug delivery and micro-reactors. In addition to the thermodynamics, the kinetics of the self-assembled nano-structures also play an important role in determining the formed structures. However, as t…

Polymeric aromatic frameworks (PAFs), easily obtained from organic platforms, as excellent supports to yield robust well-defined organometallic heterogenized catalysts.
Ligand exchange as a tool to improve quantum dot miscibility in polymer composite layers used as luminescent down-shifting layers for photovoltaic applications
UV cured luminescent CuInS 2 /ZnS quantum dot–polymer composites are prepared, their ligands are exchanged with oligomeric ligands and these composites are evaluated as down-shifting layers.
CuO/cryptomelane catalyst for preferential oxidation of CO in the presence of H 2 : deactivation and regeneration
Cryptomelane and CuO/cryptomelane catalysts have been tested in the preferential oxidation of CO in the presence of H 2 (CO-PROX reaction), paying special attention to deactivation and regeneration issues.
Enhanced piezoelectric properties and constricted hysteresis behaviour in PZT ceramics induced by Li+–Al3+ ionic pairs
Co-doping (Li+–Al3+) is a preferable approach for the piezoelectric property enhancement of ABO3-type perovskite ferroelectric ceramics.
Orthogonal strategy for the synthesis of dual-functionalised β 3 -peptide based hydrogels
We have described a new class of hydrogelator based on helical β(3)-peptides carrying a bioactive payload. The β(3)-peptides self-assemble in aqueous solution to form a nanofibrous mesh resulting in a stable hydrogel. The simple design provides the versatility for attaching different functional payloads to the β(3)-pe…
Passive tumour targeting and extravasation of cylindrical polymer brushes in mouse xenografts
The shape-persistent nature and conformation of cylindrical polymer brushes (CPBs) present opportunities to explore the properties of anisotropic (i.e. non spherical) nanomaterials in biological settings. This study shows that CPBs with lengths of up to 1 μm are able to passively target tumours via the enhanced permea…

The random packing density of nearly spherical particles
Obtaining general relations between macroscopic properties of random assemblies, such as density, and the microscopic properties of their constituent particles, such as shape, is a foundational challenge in the study of amorphous materials. By leveraging existing understanding of the random packing of spherical partic…
Competing antiferromagnetic orders in the double perovskite Mn 2 MnReO 6 (Mn 3 ReO 6 )
The new double perovskite Mn2MnReO6 has been synthesised at high pressure. Mn(2+) and Re(6+) spins order antiferromagnetically through two successive transitions that are coupled by magnetoelastic effects, as order of the Mn spins at 109 K leads to lattice distortions that reduce frustration prompting Re order at 99 K.
