The Muon g−2g-2 experiment at Fermilab

The current $\sim3.5\sigma$ discrepancy between the experimental measurement and theoretical prediction of the muon magnetic anomaly, $a_{\mu}$, stands as a potential indication of the existence of new physics. The Muon $g-2$ experiment at Fermilab is set to measure $a_{\mu}$ with a four-fold improvement in the uncertainty with respect to previous experiment, with an aim to determine whether the $g-2$ discrepancy is well established. The experiment recently completed its first physics run and a summer programme of essential upgrades, before continuing on with its experimental programme. The Run-1 data alone are expected to yield a statistical uncertainty of 350 ppb and the publication of the first result is expected in late-2019.Comment: International Workshop on e+e- collisions from Phi to Psi (PhiPsi19), C19-02-25, FERMILAB-CONF-19-180-E-PP

A new conducting polymer with exceptional visible-light photocatalytic activity derived from varbituric acid polycondensation

Abstract A novel covalent, metal-free, photocatalytic material is prepared by thermal polymerization of barbituric acid (BA). The structure of the photocatalyst is analyzed by using scanning electron microscopy, X-ray diffraction, and infrared, UV?visible, and 1H solution and 13C solid-state NMR spectroscopy. The photodegradation efficiency of BA thermally polymerized at different temperatures is tested by photocatalytic degradation of aquatic rhodamine B (RhB) dye under visible-light irradiation. It is shown that heating BA at an optimized temperature of 300 °C, that is, still in the range that polymer-like polycondensation takes place, results in a photocatalyst that can remove RhB with 96% photodegradation efficiency after 70 min exposure to visible light. The polycondensation reaction of BA is identified to process through precipitation of trimer units as primary building blocks. Reference experiments such as addition of scavengers and saturation with oxygen are studied to understand the photodegradation process. It is shown that the presence of triethanolamine, and excess of oxygen and p-benzoquinone in the solution of RhB and photocatalyst (BA300) is not beneficial, but decreases the photodegradation efficiency

A survey of islamic clergy & community leaders regarding muslim mental health first responder training

There are significant behavioral healthcare disparities for North American Muslims including limited accessibility to mental healthcare services offered with an Islamic context. Thus, American Muslims typically turn to Islamic clergy and religious community settings to address their mental health needs prior to seeking professional care. In order to improve accessibility to Islamically oriented mental health supports, the Khalil Center, an Islamically oriented Muslim mental health center, constructed an 8--hour Muslim Mental Health First Responder Training (FRT) administered across the United States and Canada to 498 community leaders and Islamic clergy. Post--training survey data found that although most of the 128 respondents were involved in settings that necessitated responding to mental health issues in their communities, 70 % had never received any previous mental health training. The overwhelming majority (80 %) of participants emphasized their appreciation of an Islamically integrated approach to the training, reporting that it changed their perceptions, attitudes, and beliefs about mental health and 92 % stated they would recommend the training to other colleagues. The majority of participants (61.7 %) in the FRT were teachers, imams/scholars, and counselors. These positions in the community have a high interpersonal impact on the community and can be considered for many people, the first line of defense against mental health-related disorders. This survey illustrated the importance of addressing mental health from a faith-based perspective in the American Muslim community and the inclusion of Islamic clergy and community leaders in order to facilitate a collaborative care approach to closing the gaps of mental health needs for the American Muslim community.Q4WOS:00061751580000

Effects of Synthesis Methods on the Physicochemical Properties of Micro- and Nano-Sized Zinc Oxide

Zinc oxide is an important semiconductor material, which is useful in various applications such as photo-electric devices electronic devices, surface acoustic wave, devices field emitters sensors, ultraviolet lasers and solar cells. With a wurtzite hexagonal phase, ZnO have a direct band gap of 3.37 eV with the larger exciton binding energy (60 meV), possesses a wide range of technological applications including flat panel displays, UV lasers and chemical and biological sensors. Till now, many methods have been developed to synthesize zinc oxide nanocrystals including vapor phase growth, ultrasonic irradiation, hydrothermal, pulsed lased deposition, vapor–liquid–solid process, soft chemical method, electrophoretic deposition, sol–gel process. Depending on the adopted synthesis method, zinc oxide nanocrystals would show various morphologies under different formation mechanisms.In this work, we studied preparation of ultra fine and nano sized ZnO by four important methods. ZnO nanoparticle, nanorod, nanowire have been successfully synthesized by facile methods like ultrasonic irradiation, sol-gel method, decomposition of Zn substrate and hydrothermal methods. In our work, three anionic surfactants Cetyl trimethylammonium bromide (CTAB), Tetrabutylammonium bromide (TBAB) and Sodium dodecyl sulfate (SDS) have been used as capping agent in the hydrothermal process. The results demonstrated that structure of the surfactant and its carbonyl chain group is important to crystal growth of the products. SEM and TEM micrograph revealed that nano fiber and ultrafine spherical ZnO prepared in the presence of CTAB and TBAB, but in the presence of SDS, sheet form of ZnO was prepared. The effect of ultrasonic irradiation was studied on preparation of ZnO. Nanoparticle of ZnO was synthesized after precipitation of zinc nitrate by urea at 90°C with irradiation of waves into the reaction flask for 2h. After heat treat at 350°C, sample was characterized with FT-IR, XRD, SEM, TEM and UV-vis. The results shows the nanoparticles of ZnO are in size range of 50-120nm. The effect of solvent was studied in this work, too. Ethanol, ethylene glycol and isopropanol were used as solvent in the reaction. In the other hand, characterization of products was shown that morphology and particle size of products was very different and depended to the dielectric constant of the solvents
