With reduction of oil resource, biodegradable polymers have attracted more and more attention due to their biodegradability. Poly(L-lactic acid) (PLLA) is one of the most important biodegradable polymers and have been used in more and more field such as materials 1 , medicine 2 , chemistry 3 , etc. However, PLLA has s…
Hollow copper(I) oxide microspheres were prepared by using polyoxyethylene (9) nonylphenyl ether (PONPE-9) as a shape controlling agent. Copper(II) sulphate and ascorbic acid were used as the starting and reducing agents, respectively. The reaction was conducted under sonication without rigid templates at a controlled…
Ultrafast electron diffraction is used to probe the photo-induced structural dynamics of single crystal (EDO-TTF)2PF6 with femtosecond time resolution. Structure factor phases at key time points are solved ab initio using the charge-flipping method.
Flat Pattern and Sloper For functional dress in contemporary daily life, most consumers pick their favorite clothes from ready-to-wear fashions. This departure from the European tradition of couture has occurred because production of an individual order requires a lot of time and money. Every piece
We demonstrate a non-thermal metallization of VO2 induced by a non-resonant excitation at frequencies around 25 THz. An ultrafast switching time of 80 fs comprises only two cycles of the driving multi-THz field.
A thermally conductive silicone, developed for high-performance potting, encapsulation and sealing applications, and that meets the UL 94 V-0 specification for flame retardancy, is available from Master Bond Inc of Hackensack, New Jersey, USA.
Covering the metal surface of blood-contacting cardiovascular implants (stents, ventricular assist devices) with functional endothelium may reduce the incidence of clotting and restenosis complications and also reduce the need for risky anticoagulation therapy following implantation of such devices. We developed a nov…
Tijdens de glazuurontwikkeling kunnen in de anorganische component van het glazuur ernstige verkleuringen ontstaan. Direct na doorbraak van de tanden is dan al sprake van een esthetisch probleem. Microabrasie van glazuur is een minimaalinvasieve] techniek voor esthetische behandeling van deze oppervlakkige defecten.
The purpose of this project was to create a functional yet stylish outfit for plus-sized individuals, appropriate for outdoor activities. The clothes are intended to promote an active lifestyle. The outfit was designed around the fabric choice of cotton and jersey knit to provide the wearer with functional comfort, wh…
When giving your presentations, you will likely be using a projector and a laptop. It’s best to make sure both your laptop and projector are turned off before you start. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm i…
A frequency selective surface (FSS) is a periodic structure in either one or two dimensions that perform a spectral and spatial filter operation on plane electromagnetic waves. Typically, an FSS will demonstrate different reflection and transmission coefficients as a function of frequency, polarisation and angle-of-pl…
A novel nickel(II) complex [Ni(phen)2(N3)2] has been synthesized, with the 1,10-phenanthroline (phen) and the nitrine (N3-) as ligands and characterized by IR spectra and single-crystal X-ray diffraction measurements. The crystal is triclinic, space group P-1 with cell dimensions of a = 8.2079(7) Å, b = 11.0042(10) Å,…
In the UK, Elga Process Water has supplied a laboratory water system to Dalton Cumbrian Facility, a nuclear research complex on the Westlakes Science & Technology Park in West Cumbria.
Nitrogen oxides are the main component of air pollution.At present, the main NOx elimination technologies are to use flue gas denitrification method.Within them selective catalytic reduction (SCR) is the most widely used manner due to its high efficiency and high selectivity.The catalyst can be divided into three type…
Cuprous oxide (Cu2O) films were electrodeposited by potentiostatic method on the indium tin oxide conductive glass substrate. The films were characterized by XRD and SEM. The electrodeposition process conditions for the preparation of Cu2O films with preferred orientations of ( According to the result of experiments,…
Silicon heterojunction metal wrap through solar cells have the potential for high efficiencies in a simple process flow. However, the non-conformal deposition of the hydrogenated amorphous silicon emitter causes specific loss mechanisms of this cell concept. The emitter does not fully cover the inner via surface. As a…
The 11th IEEE International Conference on Solid Dielectrics (ICSD) was held in Bologna, June 30 to July 4, 2013. A total of 245 registrants, and 27 accompanying persons, attended the conference. Of the registrants, 66% were from academia, and the remainder from industry and research centers. Of the registrants, 33% (8…
We applied ultrafast time-resolved near-field optical microscopy to spatio-temporal observation of plasmon dynamics in a gold nanorod. We found prominent changes of transient near-field images as time evolves, indicating coherent excitation of multiple plasmon modes.
Significance and Use 5.1 Embrittlement is a form of intercrystalline cracking that is associated with the exposure of boiler steel to a combination of physical and chemical factors. For embrittlement of boiler metal to occur, the metal must be under stres
In the realm of thermoelectric materials, Mg2Si based thermoelectric materials have gained considerable attention from researchers in recent years due to their advantages of being non-toxic, eco-friendly and the fact that their elements are relatively abundant in nature. Oxidation and volatilization were effectively a…
