Climate Change 2007: The Physical Science Basis.

Graphene’s success has shown that it is possible to create stable, single and few-atom-thick layers of van der Waals materials, and also that these materials can exhibit fascinating and technologically useful properties. Here we review the state-of-the-art of 2D materials beyond graphene. Initially, we will outline the different chemical classes of 2D materials and discuss the various strategies to prepare single-layer, few-layer, and multilayer assembly materials in solution, on substrates, and on the wafer scale. Additionally, we present an experimental guide for identifying and characterizing single-layer-thick materials, as well as outlining emerging techniques that yield both local and global information. We describe the differences that occur in the electronic structure between the bulk and the single layer and discuss various methods of tuning their electronic properties by manipulating the surface. Finally, we highlight the properties and advantages of single-, few-, and many-layer 2D materials in...

Progress, Challenges, and Opportunities in Two-Dimensional Materials Beyond Graphene

We tested the assumption, that individuals (N = 13 participants) would perform worse in a cycling endurance task and would invest less effort under ego depletion than with temporarily available self-control strength. Participants' self-control strength was experimentally manipulated (non-depletion vs ego depletion, order counterbalanced) in a within-subjects design (two points of measurement, 48 hours apart) before participants performed a 6 km time trial on an indoor track. Non-parametric bootstrapping revealed that ego depletion had the most obvious effect on power output and cycling times per lap at the beginning of the time-trial. The effect of ego depletion on revolutions per minute and heart rate was large in the early parts of the time-trial, faded somewhat during the middle, while it increased again towards the end of the time-trial. The current study suggests that it might be beneficial to develop strategies which help to replenish depleted self-control strength.

Can you go the extra mile? : the effect of ego depletion on endurance performance

Ultrafine‐grained Zn‐0.45Li alloys with high strength and ductility were fabricated by hot extrusion and multi‐pass drawing. Zn‐0.45Li alloys with enhancements in both strength and elongation have a corrosion rate and cytocompatibility similar to the values reported for biomedical implants.

As promising thermoelectric (TE) materials, Zintl-phase compounds exhibit relatively large power factor due to high mobility of charge carriers and possess very low lattice thermal conductivity κL that benefits from its complex crystal structure. Among all reported Zintl-phase thermoelectric materials, 1-2-2 layer Zintl compounds (e.g., CaZn2Sb2, Mg3Sb2, YbMg2Bi2, etc.) have been extensively studied. In this chapter, the thermoelectric properties of p-type 1-2-2 Zintl compounds will be summarized, and strategies in improving thermoelectric performance of Zintl materials will be discussed. Subsequently, recently discovered n-type Mg3Sb2-based Zintl materials will be discussed. In addition, theoretical calculation on the thermoelectric performance of other n-type 1-2-2 Zintl compounds will be presented.

Effects of tyrosine and its analogues on hCG-induced progesterone production by rat corpus luteum in vitro.

A multi-epitope antigen gene of hepatitis C virus(HCV) was fused to beta-galactosidase gene and introduced into attenuated Salmonella typhimurium SL3261 to construct HCV recombined live vaccine candidate SL3261 (pWR/PCX). when the oral live bacteria were used to immunize mice or rabbits, specific anti-GZ-PCX IgG was detected at week 6 and the strongest antibody responses happened at week 12 at a titer of 1:800 and 1:25,600 in mice and rabbits, respectively, which showed significant difference compared with those of SL3261 and blank controls. Anti-GZ-PCX sIgA in mice's intestine and anti-LPS antibody in sera were also detected. The oral live bacteria elicited obvious DTH reaction and proliferation response of peripheral lymphocytes by GZ-PCX antigen. The body weight of immunized mice slightly decreased but no other toxic effects was observed, which showed the safety of oral immunization. The study of oral live HCV multi-epitope vaccine might be able to provide a new route for the researches of HCV vaccines.
