The aim of this investigation was to understand the bioaccumulation, cell and tissue distribution and biological effects of disodium laureth sulfosuccinate (DSLS)-stabilised TiO2 nanoparticles (NPs) in marine mussels, Mytilus galloprovincialis. Mussels were exposed in vivo to 0.1, 1 and 10 mg Ti/L either as TiO2 NPs (…
Accurate determination of molecular distances is fundamental to understanding the structure, dynamics, and conformational ensembles of biological macromolecules. Here we present a method to determine the full distance distribution between small (∼7 Å radius) gold labels attached to macromolecules with very high-precis…
Two novel polyoxometalate (POM)-based coordination polymers, namely, [Co(bpz)(Hbpz)][Co(SO4 )0.5 (H2 O)2 (bpz)]4 [PMo(VI) 8 Mo(V) 4 V(IV) 4 O42 ]⋅13 H2 O (NENU-530) and [Ni2 (bpz)(Hbpz)3 (H2 O)2 ][PMo(VI) 8 Mo(V) 4 V(IV) 4 O44 ]⋅8 H2 O (NENU-531) (H2 bpz=3,3',5,5'-tetramethyl-4,4'-bipyrazole), were isolated by hydroth…
Biocompatible composites play a critical role as scaffolds in tissue engineering. Novel biocomposites made from poly(3-hydroxybutyrate) (PHB), polyhydroxyalkanoate (PHA) and bacterial cellulose (BC) in different concentrations were prepared by solution casting and their thermal and mechanical behavior as well as bioco…
BACKGROUND: In a recently discovered microorganism, Halomonas boliviensis, polyhydroxybutyrate production was extensive and in contrast to other PHB producers, contained a set of alleles for the enzymes of this pathway. Also the monomer, (R)-3-hydroxybutyrate (3HB), possesses features that are interesting for commerci…
In cells of all domains of life, reversible lysine acetylation modulates the function of proteins involved in central cellular processes such as metabolism. In this study, we demonstrate that the nitrogen regulator GlnR of the actinomycete Saccharopolyspora erythraea directly regulates transcription of the acuA gene (…
As a sustainable alternative to conventional petrochemical-based polymers, biobased and biodegradable poly( l -lactide) (PLLA) exhibits tremendous application potential in the textile industry due to its attractive elastic recovery, moisture regain, and flammability. However, the commercial adoption of PLLA textile fi…
Short in vivo circulation is a major hindrance to the widespread adoption of protein therapeutics. Protein nanocapsules generated by encapsulating proteins with a thin layer of phosphorylcholine-based polymer via a two-step encapsulation process exhibited significantly prolonged plasma half-life. Furthermore, by const…
We present a theoretical framework for understanding the wave functions and spectrum of an extensively studied paradigm for quasiperiodic systems, namely the Fibonacci chain. Our analytical results, which are obtained in the limit of strong modulation of the hopping amplitudes, are in good agreement with published num…
The morphology, microstructure, chemistry, electronic properties, and electrochemical behavior of a boron-doped nanocrystalline diamond (BDD) thin film grown on quartz were evaluated. Diamond optically transparent electrodes (OTEs) are useful for transmission spectroelectrochemical measurements, offering excellent sta…
This paper investigated the effect of carbon nanotubes (CNTs) on the electromagnetic interference shielding of carbon fiber reinforced polymer (CFRP) composites. The CNT/CFRP composites were fabricated by dry spray deposition of CNT on surfaces of carbon fiber prepregs and then out‐of‐autoclave curing process. The int…
Through resistivity measurements of an organic crystal hosting massless Dirac fermions with a charge-ordering instability, we reveal the effect of interactions among massless Dirac fermions on the charge transport. A low-temperature resistivity upturn appears robustly irrespective of the pressure and is enhanced while…
The unique atomic positions in quasicrystals lead to peculiar self-similarity and fractal-like structural morphology. Accordingly, many of the material properties are supposed to manifest exceptional characteristics. In this Rapid Communication, we explain through numerical simulations the fundamental and peculiar asp…
C 60 and single-layer MoS 2 nanocomposites were facilely prepared via a combined solvent transfer and surface deposition (STSD) method by templating C 60 aggregates on 2D MoS 2 nanosheets to construct hybrid van der Waals heterojunctions. The electronic property of the hybrid nanomaterials was investigated in a direct…
Hierarchical CuO colloidosomes (hollow spheres) constructed by subunit of open-mouthed hollow spheres that consist of 2D nanoleaves are synthesized via a Pickering emulsion strategy. Cu 2 O particles were served as emulsifier particles to form the Pickering emulsions. Self-oxidation of Cu 2 O gave rise to the formatio…
In this study, the free vibration analysis of edge cracked cantilever microscale beams composed of functionally graded material (FGM) is investigated based on the modified couple stress theory (MCST). The material properties of the beam are assumed to change in the height direction according to the exponential distrib…
In this study, the flexural behavior of sandwich composite beams made of fiber-reinforced polymer (FRP) skins and light-weight cores are studied. The focus is on the comparison of natural and synthetic fiber and core materials. Two types of fiber materials, namely glass and flax fibers, as well as two types of core ma…
Aiming to mimic a blood vessel structurally, morphologically, and mechanically, a sequential electrospinning technique using a small diameter mandrel collector was performed and a three-layered tubular scaffold composed of nanofibers of polycaprolactone, collagen, and poly(l-lactic acid) as inner, intermediate, and ou…
In the current research enterprise, behavior of novel bio-composites incorporating Aloe Vera fibers in biopolymer matrix (polylactic acid) has been experimentally examined in comparison to Sisal fiber reinforced bio-composites. These bio-composites were melt blended using single screw extruder prior to injection moldi…
Robust electrical contact of bulk conductors to two-dimensional (2D) material, such as graphene, is critical to the use of these 2D materials in practical electronic devices. Typical metallic contacts to graphene, whether edge or areal, yield a resistivity of no better than 100 Ω μm but are typically >10 kΩ μm. In thi…
