The development in the manufacturing of micro-truss structures has demonstrated the effectiveness of brazing for assembling these sandwiches, which opens new opportunities for cost-effective and high-quality truss manufacturing. An evolving idea in micro-truss manufacturing is the possibility of forming these structures in different shapes with the aid of elevated temperature. This work investigates the formability and elongation of aluminum alloy sheets typically used for micro-truss manufacturing, namely AA5083 and AA3003. Tensile tests were performed at a temperature in the range of 25-500 ○C and strain rate in the range of 2x10-4 -10-2 s-1. The results showed that the clad layer in AA3003 exhibited an insignificant effect on the formability and elongation of AA3003. The formability of the two alloys was improved significantly with values of m as high as 0.4 and 0.13 for AA5083 and AA3003 at 500 °C. While the elongation of both AA5083 and AA3003 was improved at a higher temperature, the elongation of AA5083 was inversely related to strain rate. It was concluded that the higher the temperature is the better the formability and elongation of the two alloys but at the expense of work hardening. This suggests a trade-off situation between formability and strength.

Abstract Background Trainees may not always be comfortable providing frank feedback or constructive criticism to their Program Director (PD) due to fears of negative repercussions. PDs likewise may lack the means to obtain high quality feedback from trainees, particularly among smaller training programs, e.g. fellowships. An ombudsperson is defined as an independent appointee whose task is to investigate and attempt to resolve complaints and problems. Methods The PDs from Infectious Disease (ID) and Endocrinology fellowships partnered to meet with fellows from the opposite program. Meetings were held with fellows in December and June of the academic year. Each PD started their meeting with 2 questions on a 1-10 scale: How do you rate the fellowship program? How do you rate the job the PD and program leadership are doing? Additional questions covered the fellow evaluation process, faculty feedback, education vs. service balance, and gaps in training. Additional time was allotted for fellow-raised concerns. Meeting notes were summarized anonymously and returned to the PD of the other program. Fellows were asked to complete a brief questionnaire about their experience. Results A total of 15 fellows completed the survey (6 Endocrinology, 9 ID; Table). All 15 fellows agreed that the goal of the ombudsperson review meeting (i.e. to address fellow concerns in a more confidential setting) was achieved and were comfortable sharing concerns and feedback to the ombudsperson. The majority of fellows (53%) was more comfortable sharing concerns regarding the fellowship to the ombudsperson than directly to the PD. Thirteen (87%) agreed that concerns raised during the first ombudsperson meeting were addressed by the Program in subsequent months. All fellows (100%) found it helpful that the ombudsperson was another PD and recommended that the ombudsperson review meetings should continue in the fellowship. Table. Characteristics of participants and outcomes of questions about fellowship ombudsperson program Conclusion The fellowship PD ombudsperson meeting is a novel means for soliciting constructive feedback from trainees at small training programs. Fellows were comfortable with the ombudsperson arrangement, felt the meetings achieved their goal, and recommended that the meetings continue in the future.

AbstractElectro-absorption (EA) waveguide-coupled modulators are essential building blocks for on-chip optical communications. Compared to state-of-the-art silicon (Si) devices, graphene-based EA modulators promise smaller footprints, larger temperature stability, cost-effective integration and high speeds. However, combining high speed and large modulation efficiencies in a single graphene-based device has remained elusive so far. In this work, we overcome this fundamental trade-off by demonstrating the 2D-3D dielectric integration in a high-quality encapsulated graphene device. We integrated hafnium oxide (HfO2) and two-dimensional hexagonal boron nitride (hBN) within the insulating section of a double-layer (DL) graphene EA modulator. This combination of materials allows for a high-quality modulator device with high performances: a ~39 GHz bandwidth (BW) with a three-fold increase in modulation efficiency compared to previously reported high-speed modulators. This 2D-3D dielectric integration paves the way to a plethora of electronic and opto-electronic devices with enhanced performance and stability, while expanding the freedom for new device designs.

Different Populations

Crowdsourced content creation like articles or slogans can be powered by crowds of volunteers or workers from paid task markets. Volunteers often have expertise and are intrinsically motivated, but are a limited resource, and are not always reliably available. On the other hand, paid crowd workers are reliably available, can be guided to produce high-quality content, but cost money. How can these different populations of crowd workers be leveraged together to power cost-effective yet high-quality crowd-powered content-creation systems? To answer this question, we need to understand the strengths and weaknesses of each. We conducted an online study where we hired paid crowd workers and recruited volunteers from social media to complete three content creation tasks for three real-world non-profit organizations that focus on empowering women. These tasks ranged in complexity from simply generating keywords or slogans to creating a draft biographical article. Our results show that paid crowds completed work and structured content following editorial guidelines more effectively. However, volunteer crowds provide content that is more original. Based on the findings, we suggest that crowd-powered content-creation systems could gain the best of both worlds by leveraging volunteers to scaffold the direction that original content should take; while having paid crowd workers structure content and prepare it for real world use.

Green Approach

Wide band gap semiconductors are very attractive because of their broad applications as electronics and optoelectronics materials − GaN-based materials being by far the most promising. For the production of such nitride-based optical and power devices, metal-organic chemical vapour deposition (MOCVD) is routinely used. However, this has disadvantages, such as the large consumption of ammonia gas, and the need for high growth temperature. To go beyond such a limit, in this study we successfully developed a remote plasma assisted MOCVD (RPA-MOCVD) approach for the epitaxial growth of high-quality GaN/AlGaN heterostructures on 4H-SiC substrates. Our RPA-MOCVD has the advantages of lower growth temperature (750 °C) compared to conventional MOCVD route, and the use of a remote N2/H2 plasma instead of ammonia for nitrides growth, generating in situ the NHx (x = 0−3) species needed for the growth. As assessed by structural, morphological, optical and electrical characterisation, the proposed strategy provides an overall cost-effective and green approach for high-quality GaN/AlGaN heteroepitaxy, suitable for high electron mobility transistors (HEMT) technology.
