Resumen

This paper reviews the use of optical sum frequency generation (SFG) and second harmonic generation (SHG) microscopy under ultra-high vacuum (UHV) conditions to observe the dynamics of a hydrogen terminated Si(111)1 × 1 surface. First, we took SFG and SHG microscopic images of the surface after IR light pulse irradiation and found that the SHG and nonresonant SFG signals were enhanced, probably due to the formation of dangling bonds after hydrogen desorption. Second, we observed time-resolved SFG intensity images of a H–Si(111)1 × 1 surface. After visible pump light irradiation, the nonresonan

Resumen

The title compound, C2H3N3OS, is a monoclinic (P21/c) polymorph of the previously reported triclinic structure [Kanget al.(2012).Acta Cryst.E68, o1198]. The asymmetric unit contains two independent molecules which are essentially planar, with r.m.s. deviations of 0.001 and 0.032 Å from the mean plane defined by the seven non-H atoms. In the crystal, N—H...N and N—H...O hydrogen bonds link the molecules into a sheet parallel to (111).

Resumen

X-ray diffraction (XRD) results indicate that the NiFe thin films had a face-centered cubic (FCC) structure. Post-annealing treatment increased the crystallinity of NiFe films over those at room temperature (RT), suggesting that NiFe crystallization yields FCC (111) texturing. Post-annealing treatments increase crystallinity over that obtained at RT. This paper focuses on the maximum alternative-current magnetic susceptibility(χac)value of NiFe thin films with resonance frequency(fres)at low frequencies from 10 Hz to 25000 Hz. These results demonstrate that theχacof NiFe thin films increased w

Resumen

The R&D of highly active and durable cathode catalysts for the oxygen reduction reaction (ORR: O2 + 4H+ + 4e−→2H2O) is very important for polymer electrolyte fuel cells (PEFCs). Bimetallic alloys of Pt such as Pt−Co exhibit higher ORR activities than that of pure Pt. It was found for polycrystalline Pt alloy electrodes that the dissolution of the surface was followed by a rearrangement of the Pt atoms, resulting in a Pt-skin layer, which can protect the underlying bulk alloy.1, 2 It was also shown that a modified electronic structure at the Pt-skin layer induced enhanced ORR activity.1, 2

We investigated the association between KCNH2 polymorphisms and QTc intervals among Malay opioid-dependent methadone maintenance treatment (MMT) recipients. A cross-sectional study was conducted involving 111 patients with stable methadone dosage for at least 6 months attending several methadone clinics in Kelantan, Malaysia between March 2011 and October 2012. Those with cardiac structural defects, recipients of other QTc-prolonging pharmacotherap

Resumen

Knowledge about clean and healthy life in children needs to be given early to shape behavior in everyday life. Knowledge about healthy living can be provided at school through various learning programs. This study aims to find the effectiveness of health promotion programs (JUMSIH) to increase children's knowledge about clean and healthy living. The research method is a pre-experimental one-shot case study design. The respondents of this study were 68 students aged 7-8 years.

Resumen

BL13-XALOC is currently the only macromolecular crystallography beamline at the 3 GeV ALBA synchrotron near Barcelona, Spain. The optics design is based on an in-vacuum undulator, a Si(111) channel-cut crystal monochromator and a pair of KB mirrors. It allows three main operation modes: a focused configuration, where both mirrors can focus the beam at the sample position to 52 µm × 5.5 µm FWHM (H × V); a defocused configuration that can match the size of the beam to the dimensions of the crystals or to focus the beam at the detector; and an unfocused configuration, where one or both mirrors ar

We synthesized silver nanoparticles of different sizes and forms as function of the molar masses of AgNO3, in two different solvent mediums (ethanol, methanol). We carried out the synthesis according to standard chemical route with major modifications. The spectroscopic characterization showed the presence of two distinct absorption bands; the first band at 300 nm and the second shifted to 440 nm. We found a multipolar phenomenon depending on the temperature. The shape and size predicted by the numerical model are conform to the experimental results.

Ionic liquids (ILs) are a unique class of electrolytes, which characteristics make them suitable for use in solar cells, supercapacitors, and fuel cells1. Due to the appealing properties such as good electrochemical stability, low vapour pressure, high concentration of ions and the lack of solvent, they have been under intense study since the early 2000s. Although numerous theoretical2,3, computational4,5, and experimental studies6,7 have shed light on the interfacial properties of ILs, which differ noticeably from the aqueous electrolytes, multiple open questions remain.

Resumen

Cellulose is the main raw material for the production of paper. Companies that produce it present in their production line the cutting of the cellulose sheet. This failure is sporadic and has a high economic impact since it paralyzes the production line for several hours, incurring unproductive hours and a large deployment of human and financial resources. In this research, the use of Data Mining is proposed to define a machine learning algorithm that allows predicting the cutting of the cellulose sheet in a production line of a cellulose plant in Chile.

We showed safe induction of antibody (ab) responses to 5 of the 7 vaccine AGs. Data has shown that tumor vaccine efficacy may be enhanced through disruption of angiogenesis thus providing a rationale for combining BEV with the polyvalent vaccine.

Resumen

Atomic diffusion bonding (ADB) of wafers using thin films is a promising process to achieve room-temperature wafer bonding [1]. For ADB processing, thin oxide [2] and nitride [3] films are useful for bonding, as are thin metal films [1]. For blade testing, a conventional method to examine the surface free energy at the bonded interface γ, the debonding length L is measured after a thin blade is inserted between the bonded wafers. The value of γ is calculated using L values. For a bonded interface such as Si/SiO2 or SiO2/SiO2, stress corrosion caused by oxygen and water gases in air is well-kno

Laurel wilt, caused by Raffaelea lauricola, a fungal symbiont of the redbay ambrosia beetle, Xyleborus glabratus, is responsible for extensive mortality of native redbays (Persea borbonia and P. palustris) in the coastal plains of the southeastern United States (1). The wilt also affects the more widespread sassafras, Sassafras albidum, particularly in areas where diseased redbays are common and populations of X. glabratus are high. Because sassafras stems were thought to lack chemicals that are attractive to the beetle, and sassafras tends to be widely scattered in forests, it was believed th
