Room-temperature thermoelectric materials are important for converting heat into electrical energy.As a widebandgap semiconductor material,CuI has the characteristics of non-toxicity,low cost,and environmental friendliness.In this work,CuI powder was synthesized by a wet chemical method,then CuI film was formed by vacuum assisted filtration of the CuI powder on a porous nylon membrane,followed by hot pressing.The film exhibits a large Seebeck coefficient of 600μV·K^(-1)at room temperature.In addition,the film also shows good flexibility(~95%retention of the electrical conductivity after being bent along a rod with a radius of 4 mm for 1000 times).A finger touch test on a single-leg TE module indicates that a voltage of 0.9 mV was immediately generated within 0.5 s from a temperature difference of 4 K between a finger and the environment,suggesting the potential application in wearable thermal sensors.

nylon 66 has been widely used for numerous mechanical applications but its sliding wear mechanisms are not fully understood.In particular,limited attention has been paid to the generation of fatigue surface cracks under constant and cyclic load conditions.The present work focuses on the effect of load frequency on the wear behavior of a polymer with surface defects in dry sliding conditions.The defects were imposed vertical deep cracks perpendicular to the direction of sliding.Wear studies were conducted against a steel counterface at constant loads,and in cyclic loads at different frequencies.Artificial neural network(ANN)models were examined to identify one that optimally simulates wear under the applied load parameters.Surface cracks were found to have a remarkable adverse effect on the wear behavior of the polymer.The wear rates were influenced by the number of cracks as well as the type of applied load.Furthermore,results suggest that the presence of surface cracks is attributable to the section B wear regime.Finally,acceptable predicted wear rate values were obtained by introducing the ANN wear model.

nylon-6 has been modified by polyorganosiloxane. It was realized by radical addition of caprolactam to the vinyl group of silicone and anionic polymerization of the monomer in the presence of the silicone macromer. The mechanical properties of the modified plastics are not far from that of the unmodified one whereas its frictional properties are significantly improved.

Barbed surgical sutures have attracted worldwide attention in recent years. The plurality of barbs projecting out and penetrating into surrounding tissue eliminates the need for tying a knot. In the current study,nylon and polypropylene( PP) barbed sutures with two different barb geometries designed to anchor in porcine skin and tendon tissues were fabricated by a specially designed mechanical cutting machine. The tensile properties were compared between the barbed and unbarbed control sutures. The in vitro tissue anchoring ability was measured by two tissue /suture pullout tests,one for skin and the other for tendon tissue. Regardless of the type of tissue,the PP barbed suture with its higher modulus had a superior anchoring ability. Given the same suture material,improved anchoring performance was shown in tendon tissue.

The luminescent fibers have a good application prospect.The feature of this paper is that efficient luminescent nylon 6(PA6)composite nanofibers are successfully prepared by electrospinning.The luminescent PA6 composite nanofibers composed of PA6,Eu(BA)3Phen and Tb(BAO)3Phen(BA=P-methylbenzoic acid,BAO=P-methoxybenzoic acid,and Phen=1,10-phenanthroline).The structure and properties were characterized by scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FT-IR),fluorescence spectroscopy,and thermogravimetriy(TG)analysis.The correspondence between polymer matrix and as-prepared composite nanofibers properties has also been studied in detail.Through using hexafluoroisopropanol(HFIP)as solvent,Eu(BA)3Phen/PA6 and Tb(BAO)3Phen/PA6 composite nanofibers exhibit good luminescence properties.It is noted that only 5%rare earth luminescent materials are added to Tb(BAO)3Phen/PA6 composite nanofibers,and the luminescence intensity of the as-prepared nanofibers reaches half that of the pure rare earth luminescent materials.Furthermore,uniform dispersion of pure rare earth luminescent materials in the as-prepared nanofibers gives the composite nanofibers good mechanical properties and thermal stability.These results provide an important basis for the preparation and wide application of new PA6 luminescent fibers.

Here we report the use of plastics by Chrysomus ruficapillus(Vieillot,1819)(Passeriformes:Icteridae),popularly known as“Garibaldi”,in its nesting activities.The phenomenon was registered on October 17,2020 near Furnas reservoir,upper Parana River Basin,in Minas Gerais,southeastern Brazil.We also discuss the possible negative effects-e.g.,asphyxiation,entanglement-for C.ruficapillus using plastic materials in nesting activities.Finally,we call attention to the need for further investigations about similar events in other Brazilian watersheds.

The kineties of non-isothermal crystallization of nylon-1010 has been investigated by using differential scanning calorimetry(DSC), DSC curves were obtained under cooling rate(R): 2. 5, 5, 10, 20, 40K/min. Applying Mandelkern and Ziabicki theories, the values of the Z kinetic parameter and G the kinetic crystalllzab- ility have been determined. Expenents of Avrami obtained in this work decrease with increase of cooling rate and then level off. The experimental results show disagreements with the Ozawa equation.
