Cu2O porous nanostructured films fabricated by positive bias sputtering deposition.

Nanotechnology 2018 Dec 11. Epub 2018 Dec 11.

Changzhou University, Changzhou, 213164, CHINA.

In this work, the authors fabricated Cu2O porous nanostructured films (PNFs) on glass slide substrates by the newly developed positive bias deposition approach in a balanced magnetron sputtering (MS) system. It was found that the surface morphology, crystal structure and optical property of the as-deposited products were greatly dependent on the applied positive substrate bias. In particular, when the substrate was biased at +50 V and +150 V, both of the as-prepared Cu2O PNFs exhibited a unique triangular pyramids-like structure with obvious edges and corners and little gluing, a preferred orientation of (111) and a blue shift of energy band gap at 2.

Mechanical loading releases osteoclastogenesis-modulating factors through stimulation of the P2X7 receptor in hematopoietic progenitor cells.

J Cell Physiol 2018 Dec 7. Epub 2018 Dec 7.

Department of Clinical and Experimental Medicine, Division of Cell Biology, Linköping University, Linköping, Sweden.

Mechanical instability of bone implants stimulate osteoclast differentiation and peri-implant bone loss, leading to prosthetic loosening. It is unclear which cells at the periprosthetic interface transduce mechanical signals into a biochemical response, and subsequently facilitate bone loss. We hypothesized that mechanical overloading of hematopoietic bone marrow progenitor cells, which are located near to the inserted bone implants, stimulates the release of osteoclast-inducing soluble factors.

Chemistry 2018 Dec 10. Epub 2018 Dec 10.

Latvian Institute of Organic Synthesis, LATVIA.

Aiming to develop all-organic bipolar semiconductors with high charge mobility and efficient E-type fluorescence (so-called TADF) as environmentally-friendly light-emitting materials for optoelectronic applications, four noble metals-free dyes with linear and V-shapes were designed using accepting pyridine-3,5-dicarbonitrile and donating carbazole units. Exploiting donor-acceptor design strategy and using moieties with different donating and accepting abilities, TADF emitters with wide variety of molecular weights were synthesized for getting optimum combination of charge-transporting and fluorescent properties in one TADF molecule. Depending on molecule structures, different TADF emitters capable of emitting in the range from 453 to 550 nm with photoluminescence quantum yields up to 98% for the solutions in oxygen-free toluene were obtained.

Bioinspired catecholamine/starch composites as superadsorbent for the environmental remediation.

Int J Biol Macromol 2018 Dec 4. Epub 2018 Dec 4.

Chemical Engineering Department, University of Mohaghegh Ardabili, P.O. Box 179, Ardabil, Iran.

Focusing on the encouraging properties of starch-based composite materials, starch‑g‑(acrylic acid‑co‑acrylamide) superabsorbent was synthesized using solution polymerization method, and then the catecholamine functional groups were introduced on to pore surface of the absorbent via oxidative polymerization of dopamine (DA). The adsorbent was optimized in terms of the monomers' mass ratio and synthesis conditions, and characterized by different characterization techniques. The polydopamine (PDA) coating thickness was estimated using transmission electron microscopy (TEM) image and it was found to be 83 nm. Read More

Effect of body length, trophic position and habitat use on mercury concentrations of sharks from contrasted ecosystems in the southwestern Indian Ocean.

Environ Res 2018 Nov 23;169:387-395. Epub 2018 Nov 23.

Blue Ventures, Level 2 Annex, Omnibus Business Centre, 39-41 North Road, London N7 9DP, United Kingdom.

The non-essential metal mercury (Hg) can have deleterious effects on health of organisms, and tends to bioaccumulate with age in long-lived organisms and to biomagnify along food webs. Because elasmobranchs are fished for human consumption and their Hg levels are frequently above the maximum Hg concentration recommended for fish consumption, understanding the drivers of Hg concentration is of considerable interest. Total Hg concentrations were analysed in muscle tissues of 14 shark and 2 batoid species (n = 339 individuals) sampled across multiple habitats (coastal, open ocean and bathyal) in the southwestern Indian Ocean.

Parrot Genomes and the Evolution of Heightened Longevity and Cognition.

Curr Biol 2018 Nov 28. Epub 2018 Nov 28.

Department of Behavioral Neuroscience, Oregon Health & Science University, Portland, OR 97239, USA. Electronic address:

Parrots are one of the most distinct and intriguing groups of birds, with highly expanded brains [1], highly developed cognitive [2] and vocal communication [3] skills, and a long lifespan compared to other similar-sized birds [4]. Yet the genetic basis of these traits remains largely unidentified. To address this question, we have generated a high-coverage, annotated assembly of the genome of the blue-fronted Amazon (Amazona aestiva) and carried out extensive comparative analyses with 30 other avian species, including 4 additional parrots.

Calcium lactate as an attractive compound to partly replace salt in blue-veined cheese.

J Dairy Sci 2018 Oct 24. Epub 2018 Oct 24.

VetAgro Sup, 89 Avenue de l'Europe, 63370 Lempdes, France; Université Clermont Auvergne, INRA, Mixed Research Unit on Cheese (UMRF), F-15000 Aurillac, France.

In addition to their high sodium content, cheeses are thought to induce an acid load to the body, which is associated with deleterious effects on consumers' health. Our objective was to explore the use of alkalinizing salts in partial substitution of NaCl to reduce both the sodium content and the acid-forming potential of cheese, without altering its sensory properties. Blue-veined cheeses were produced under industrial conditions, using brine salting followed by dry salting with a 4:1 (wt/wt) mixture of calcium lactate:NaCl or calcium citrate: NaCl. Read More
