Effects of Gold Nanorods on Nonlinear Properties of Graphene Films Using Z-Scan Technique

Two dimensional nanomaterials, specifically graphene, can play a significant role in various photonic and electronic devices. This is especially true in handling the enormous heat in high density electronics and in nonlinear optics when using high power lasers. To model these systems it is important to know the thermal-optical properties of graphene. In this paper, we report on the thermal and optical linear and nonlinear properties of graphene materials using Z-scan system. In particular, we explore the thermo-optical properties of graphene, with and without gold nanorods （AuNRs）. The obtained results illustrate that the addition of gold nanorods causes a significant change in thermal nonlinear refractive index coefficients of graphene, due to the plasmonic enhancements.

What Would Vitruvius Do？ Re-thinking Architecture Education for the 21st Century University

In the 1996 AIA （American Institute of Architecture） Convention in Minneapolis, the governing bodies in the education and professionalization of architects in the US （namely, the American Institute of Architecture, American Institute of Architecture Students, National Council of Architectural Registration Boards, National Architecture Accrediting Board and the Association of Collegiate Schools of Architecture） released the Boyer Report, subsequently published as Building Community： A New Future for Architecture Education and Practice. The report was named in honor of Ernest Boyer, an educational theorist who also participated in writing the text. Less comprehensive than the canonical texts by Marcus Vitruvius Pollio and his interlocutors, it is nonetheless a mirror of our current assumptions about the education of the architect. This paper looks at the epistemology inherited from Vitruvius as it shapes pedagogy up and through the Boyer Report and into the 21 st century. Using a method of comparative analysis applied to past and current architecture programs, our argument is that historical divisions between professional or applied knowledge and liberal or theoretical knowledge inherited from the past limit our capacity within architecture education to integrate new strategies for knowledge creation and dissemination. It is concluded that any serious revision of architecture education means a systematic reconsideration of the basis of architecture knowledge. What of the （persistent） Vitruvian model is relevant in our post-modern condition？ What do we learn from the image of our profession projected through the lens of the Boyer Report and it is like？ In other words, what would Vitruvius do？

Atomic Layer Deposition of High-Capacity Anodes for Next-Generation Lithium-Ion Batteries and Beyond

Electrification has great impacts on our modern society.To electrify future transportation,state-of-the-art lithium-ion batteries(LIBs)are still not sufficient in multiple aspects including cost,energy density,lifespan,and safety.To this end,next-generation high-energy LIBs and beyond are highly regarded.In this regard,high-capacity anodes are undergoing intensive investigation,such as silicon,SnO_(2),and lithium metal.However,such anode materials are commonly experiencing large volume changes and related issues,which are reflected on mechanical degradation,capacity fading,low efficiency,and unsatisfactory lifetime.To address these challenges,many technical strategies have been investigated.In the past decade,atomic layer deposition(ALD)has emerged as a new promising technique enabling atomic-scale surface modification and nanoscale design of high-capacity anodes for high performance.In this review,recent ALD studies on developing high-capacity anodes for LIBs and beyond are thoroughly summarized.In addition,ALD strategies and their effectiveness in pursing high-energy LIBs and beyond are discussed.Particularly,we highlighted the latest advances of ALD for addressing the notorious issues associated with Li metal anodes.It is expected that this work will promote the applications of ALD in new battery systems.

Tribological behavior of polydopamine/polytetrafluoroethylene coating on laser textured stainless steel with Hilbert curves

Shallow Hilbert curve patterns with easily programmable texture density were selected for laser texturing of stainless steel substrates.Two different texture path segment lengths(12 and 24 μm)and four different laser power percentages(5%,10%,15%,and 20%)were investigated.The textured and smooth substrates were coated with thin polydopamine/polytetrafluoroethylene(PDA/PTFE)coatings for tribological property assessment.The effects of texture density(texture area coverage)and laser power on the durability and friction of the coated surfaces were studied.Laser texturing the substrates improved the coating durability up to 25 times,reduced the friction coefficient,and prevented coating global delamination.The textures fabricated with a laser power of 15%and a texture path segment length of 12 μm yielded the best coating durability.The textures provided the interlocking for the PTFE coating and thus prevented its global delamination.Furthermore,the PTFE inside the texture grooves replenished the solid lubricant worn away in the wear track and prolonged the coating wear life.

p-RWBO:a novel low-collision and QoS-supported MAC for wireless ad hoc networks

QoS supported MAC mechanism is a key issue for supporting QoS in wireless ad hoc networks. A new backoff algorithm, named RWBO＋BEB, was proposed previ- ously to decrease the packet collision probability significantly. In this paper, it is explored how to make RWBO＋BEB support service differentiation in wireless ad hoc networks, and a novel proportional service differentiation algorithm, named p-RWBO, is proposed to allocate the wireless bandwidth according to the band- width ratio of each station. In p-RWBO, station n＇s walking probability （Pw,n） is selected according to its allocated bandwidth ratio. An analytical model is proposed to analyze how to choose Pw, n according to the bandwidth ratios of station n. The simulation results indicate that p-RWBO can differentiate services in terms of both bandwidth and delay.
