Increasing phosphor layer thickness and concentration can enhance the lumen flux of white LED (W-LED). In this work, we found that increasing the phosphor layer thickness and concentration can increase its temperature, and there is also a maximum thickness and concentration beyond which their increase will not lead to lumen increase, but only temperature increase. Higher thickness and higher concentration also results in warm light instead of White light. The maximum thickness and concentration are found to be limited by the scattering of light rays with higher % decrease of blue light rays than the yellow light rays. The results obtained in this work can also be used to compute the temperature and thermo-mechanical stress distribution of an encapsulated LED, demonstrating its usefulness to the design of encapsulated LED packages. Simulation software like ANSYS and TracePro are used extensively to verify the root cause mechanisms.

Polarization-dependent hard X-ray excited optical luminescence (XEOL) was used to study not only the optical properties but also the crystallographic orientations of a non-polar a-plane ZnO wafer. In addition to a positive-edge jump and extra oscillations in the near-band-edge (NBE) XEOL yield, we observed a blue shift of the NBE emission peak that follows the polarization-dependent X-ray absorption near-edge structure (XANES) as the X-ray energy is tuned across the Zn K-edge. This NBE blue shift is caused by the larger X-ray absorption, generating higher free carriers to reduce the exciton-LO phonon coupling, which causes a decrease in the exciton activation energy. The extra oscillations in XANES and XEOL as the polarization is set parallel to the c-axis is attributed to simultaneous excitations of the Zn 4p - O 2p pi-bond along the c-axis and the bilayer sigma-bond, whereas only the sigma-bond is excited when the polarization is perpendicular to the c-axis. The polarization-dependent XEOL spectra can be used to determine the crystallographic orientations. (c) 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement

Electrically pumped GaAs-based photonic crystal surface emitting lasers were fabricated using a simple fabrication process by directly capping the indium-tin-oxide transparent conducting thin film as the top cladding layer upon a photonic crystal layer. Optimization of the separate-confinement heterostructures of a laser structure is crucial to improving characteristics by providing advantageous optical confinements. The turn-on voltage, series resistance, threshold current, and slope efficiency of the laser with a 100 x 100 mu m(2) photonic crystal area operated at room temperature were 1.3V, 1.5 Omega, 121mA, and 0.2W/A, respectively. Furthermore, we demonstrated a single-lobed lasing wavelength of 928.6 nm at 200mA and a wavelength redshift rate of 0.05 nm/K in temperature-dependent measurements. The device exhibited the maximum output power of approximately 400 mW at an injection current of 2 A; moreover, divergence angles of less than 1 degrees for the unpolarized circular-shaped laser beam were measured at various injection currents. Overall, the low threshold current, excellent beam quality, small divergence, high output power, and high-operating-temperature (up to 343K) of our devices indicate that they can potentially fill the requirements for next-generation light sources and optoelectronic devices.

Here we present the first Vacuum UltraViolet (VUV) photoabsorption spectra of ice analogues of Pluto and Charon ice mixtures. For Pluto the ice analogue is an icy mixture containing nitrogen (N-2), carbon monoxide (CO), methane (CH4) and water (H2O) prepared with a 100:1:1:3 ratio, respectively. Photoabsorption of icy mixtures with and without H2O were recorded and no significant changes in the spectra due to presence of H2O were observed. For Charon a VUV photoabsorption spectra of an ice analogue containing ammonia (NH3) and H2O prepared with a 1:1 ratio was recorded, a spectrum of ammonium hydroxide (NH4OH) was also recorded. These spectra may help to interpret the P-Alice data from New Horizons. (C) 2017 Elsevier B.V. All rights reserved.

p-Phenediamino-modified graphene (PDG) has been newly synthesized via a facile green one-step chemical route as a functionalized graphene-based additive to copolymerize with aniline for fabricating innovative PDG/polyaniline conducting polymer composites containing very special semi-interpenetrating networks (S-IPNs). The S-IPNs not only provide additional pathways by creating chemically bonded PDG and PANI for smoothly transporting carriers but greatly reduce the amount of graphene required to less than a few percent could effectively improve the overall electrical conductivity, Seebeck coefficient, and thus the thermoelectric (TE) performance. The found optimized TE figure of merit (ZT) of 0.74 approaches a practical high level which is comparable or much higher than previously reported ones for TE polymers.

Graphene oxide (GO) has wide application potential owing to its 2D structure and diverse modification sites for various targeted uses. The introduction of magnetism into GO structures has further advanced the controllability of the application of GO materials. Herein, the concept of modular design and modeling was applied to tune the magnetism of GO. To obtain desirable magnetic properties, diradicalstructured GO patches were formed by the introduction of two functional groups to break the Kekule structure of the benzene ring. In these diradical GO patches, the energy of the triplet state was lower than those of the open-shell broken-symmetry singlet state and closed-shell singlet state. To create such multi-radical patches, a practical approach is to determine a substantial spatial separation of the alpha and beta spin densities in the molecule. Thus, systematic design strategies and tests were evaluated. The first strategy was extending the distance between the distribution center of the alpha and beta spin densities; the second was controlling the delocalization directions of the alpha and beta electrons; the third was controlling the delocalization extension of the alpha and beta electrons by oxidative modification, and finally introducing multi-radical structures into the molecular system and controlling the position of each radical. Herein, successful paves the way to explore ferromagnetic MGO guided by theoretical study, which may become reality soon.

We developed a naphthalimide-based, lysosome-targeting, and self-immolative fluorescent probe for H2S detection. Probe LS-1 comprises a 2-formylbenzoate derivative of the 1,8-naphthalimide fluorophore. H2S forms a thiohemiacetal intermediate by reacting with the formyl group of the 2-formylbenzoate derivative, which subsequently undergoes intramolecular cyclization with the ester moiety to generate a free naphthalimide fluorophore (FL-1). The UV-vis absorbance (lambda(abs)) value of probe LS-1 at 450 nm increased in the presence of H2S. Similarly, with increasing H2S concentrations, the emission band (lambda(em)) centered at 560 nm increased gradually. The probe was found to be highly sensitive and chemoselective towards H2S compared with other biological analytes. Probe LS-1 was nontoxic and very stable across the physiological pH range. The probe LS-1 enables the detection of intracellular endogenous H2S formation in HT29 cells in lysosomes.

Enzymes containing heme, nonheme iron, or copper active sites play an essential role in the dioxygen binding and activation for substrate oxidation. The conceptual challenges to the quantitative modeling of this primary catalytic step arise from (1) instrinsic electronic nonadiabaticity of the spin flip events of the triplet dioxygen molecule (O-3(2)), mediated by spin-orbit coupling and (2) possible heat dissipation channels, due to the high exothermicity of dioxygen binding processes. Herein, the spin-forbidden dioxygen binding dynamics of a reduced heme model was directly investigated in terms of the nonadiabatic trajectory surface-hopping dynamics, involving the coupled singlet, triplet and quintet states. This work reveals the complexity of this elemental reaction, and the binding/dissociation dynamics of iron peroxo species is important to interpret the subsequent H atom abstraction reaction step. Furthermore, we identify nonadiabatic dynamical effects that could not be observed through traditional calculations of static geometries.

The crossbar structure of resistive random access memory (RRAM) is the most promising technology for the development of ultrahigh-density devices for future nonvolatile memory. However, only a few studies have focused on the switching phenomenon of crossbar RRAM in detail. The main purpose of this study is to understand the formation and disruption of the conductive filament occurring at the crossbar center by real-time transmission electron microscope observation. Core-shell Ni/NiO nanowires are utilized to form a cross-structure, which restrict the position of the conductive filament to the crosscenter. A significant morphological change can be observed near the crossbar center, which results from the out-diffusion and backfill of oxygen ions. Energy dispersive spectroscopy and electron energy loss spectroscopy demonstrate that the movement of the oxygen ions leads to the evolution of the conductive filament, followed by redox reactions. Moreover, the distinct reliability of the crossbar device is measured via ex situ experiments. In this work, the switching mechanism of the crossbar core-shell nanowire structure is beneficial to overcome the problem of nanoscale minimization. The experimental method shows high potential to fabricate high-density RRAM devices, which can be applied to 3D stacked package technology and neuromorphic computing systems.

Metal/metal oxides have attracted extensive research interest because of their combination of functional properties and compatibility with industry. Diffusion and thermal reliability have become essential issues that require detailed study to develop atomic-scaled functional devices. In this work, the diffusional reaction behavior that transforms piezoelectric ZnO into magnetic Fe3O4 is investigated at the atomic scale. The growth kinetics of metal oxides are systematically studied through macro- and microanalyses. The growth rates are evaluated by morphology changes, which determine whether the growth behavior was a diffusion- or reaction-controlled process. Furthermore, atom attachment on the kink step is observed at the atomic scale, which has important implications for the thermodynamics of functional metal oxides. Faster growth planes simultaneously decrease, which result in the predominance of low surface energy planes. These results directly reveal the atomic formation process of metal oxide via solid-state diffusion. In addition, the nanofabricated method provides a novel approach to investigate metal oxide evolution and sheds light on diffusional reaction behavior. More importantly, the results and phenomena of this study provide considerable inspiration to enhance the material stability and reliability of metal/oxide-based devices.

The photoelectrochemical (PEC) water splitting activity of Nb and Ta-doped hematite (alpha-Fe2O3) nanorods was investigated with reference to electronic structures by in situ synchrotron x-ray absorption spectroscopy (XAS). Current density-potential measurements demonstrate that the PEC activity of alpha-Fe2O3 nanorods depends strongly on the species and concentrations of dopants. The doping of alpha-Fe2O3 nanorods with a low level of Nb or Ta can improve their electrical conductivity and thereby facilitate charge transport and reduced electron-hole recombination therein. The photoconversion effects of Nb and Ta-doped alpha-Fe2O3 by in situ XAS in the dark and under illumination revealed opposite evolutions of the spectral intensities of the Fe L-edge and Nb/Ta L-edge, indicating that charge transfer and a conduction pathway are involved in the photoconversion. Analytic in situ XAS results reveal that the alpha-Fe2O3 that is doped with a low level of Nb has a greater photoconversion efficiency than that doped with Ta because Nb sites are more active than Ta sites in alpha-Fe2O3. The correlation between PEC activity and the electronic structure of Nb/Ta-doped alpha-Fe2O3 is examined in detail using in situ XAS and helps to elucidate the mechanism of PEC water splitting in terms of the electronic structure.
發現不曾知道的美好──登山社期末大山初體驗

一直以來，對於登山的印象就是折磨自己，但是忘記是在什麼樣的瞬間，這學期決定去嘗試看看這個一直敬而遠之的活動。第一天就在忐忑不安中，搭了半天的車到達了登山口紮營。就在太陽下山的剎那，大地瞬間被黑暗吞沒，伸手不見五指，我們立刻拿出頭燈，就著微弱的燈光吃著熱騰騰的麵，而後回到帳篷收拾了一下明天的裝備後，就休息了。那時還不到8點，完完全全體會到所謂的「日落而息」。第二天背著重裝，我們啟程走向13公里外的天池山莊。起初，吹拂到我們臉上的風還是冷冰冰的，但越走身體越熱，本來穿著的保暖衣物全都收到了背包中。一路上，我們沒有說太多的話，專心注意著腳下的碎石路，也不忘抬頭看遠方山頭層巒疊嶂的美景。六個小時後，我們終於抵達了目的地。大家卸下了肩上的重擔，開始幫忙準備晚餐。我忙裡偷閒地到外頭欣賞美麗的日落──山，真的很奇妙，每時每刻都呈現出不同的樣子，美得讓人捨不得眨眼。行前心裡其實非常的緊張，畢竟是從沒有接觸過的活動。但現在想想，好像很多時候人總是要有一個不小心腦衝的瞬間，才會走出自己的舒適圈，發現從來不曾知道的美好。隔天我們趕在太陽升起前，往奇萊南峰的路上邁進。我們行進速度極為緩慢，因為在一個晚上的低溫下，地上結了冰，不方便行走。在山巒之間的空隙，我們還看到了花蓮的燈火在黑夜之中閃耀，遠遠地看著它們的靜謐，彷彿可以聽見人們睡夢中的呼吸一樣，安詳得美麗。登上奇萊南峰前的陡坡，痛苦得讓人想放棄。走了兩天的碎石路已不在，只剩草原和堅硬的石頭聳立在峭壁上，大家每一步都走得艱辛，每一步都要死命抓著周圍的雜草，才可以穩住自己往上走。對有點懼高的我來說，這種幾近瀕死的感覺讓我簡直快要窒息，但是我沒有退路，沒有可以退縮的選擇，只能前進。

《我就要你好好的》（Me Before You）
(國立陽明大學, 2018-02-09)
黃柏威
電影《我就要你好好的》（Me Before You），改編自美國暢銷作家Jojo Moyes的同名小說《Me Befoe You》，故事描述一個失業的英國小鎮姑娘Lou，到富豪人家擔任看護，照顧因車禍而四肢癱瘓的Will。一開始，傻里傻氣的Lou在這裡顯得格格不入，但在Will敞開心扉之後，兩人的互動與陪伴漸漸改變了彼此。特別是Lou，原是她想要改變Will意志消沉的生命態度，但最後反而是Will改變了她，幫助她離開原先的生命困局，開啟人生新的可能。電影一開始，Lou在咖啡廳裡工作，工作認真、態度親切的她深得顧客喜愛，但她個人的努力卻也難敵小鎮蕭條的經濟。咖啡廳關門後，她失去了工作。她想去念大學，但得要照顧父母的她，卻沒有條件離開家鄉小鎮，只能在這片貧土上繼續尋找機會。 Lou的個性樂觀率真，尤其自由奔放的穿衣風格更引人醒目，雖然那在別人眼裡看來是毫無美感的怪異與不搭，但Lou不改其性，並沒那麼在乎別人眼光。她不追隨時尚潮流，因為美醜都是主觀經驗，而她知道那是屬於自己的快樂，她珍惜這些快樂。而這或許也是Will從Lou身上看到的珍貴特質，Lou和那些在派對上想接近他的金髮妹子不同，Lou沒有矯情做作，Lou也沒有假裝成不是自己的樣子。相較於Lou，Wil則是活在不同世界的人，他的家世彷彿富可敵國，而他就像是童話裡的白馬王子，英俊帥氣、人品又佳，既是運動好手又是商界明星。他什麼也不缺，直到車禍奪走了他的行動力，他只能坐在輪椅上。雖然他享有完善的照顧，但當知道自己無法恢復時，他漸漸失去了生存意志；他困在過去的自我形象裡，難以走向未來。就像他曾對Lou說的，他看過最美的風景是巴黎街頭的咖啡館，但他不願以現在的形象重訪，他想要用「健康」的自己造訪。這都訴說著他難以接納現在的自己。雖然Lou的逗趣讓Will重拾笑容，而Lou也努力想藉著「最終清單」幫助Will走出封閉的自我。但原來這也是Will幫助Lou的方式。遇見Lou之後，Will被她的天真打動，他給了Lou資源與機會，幫她走出原先受限的環境；他打開了Lou的視野，最終讓Lou有機會追求自己的夢想。或許故事想避開老掉牙的勵志情節，沒有要讓Will透過Lou的幫助，扭轉生命態度，嘗試去接納不一樣的自己。但這安排反倒變成另種困境，讓Will所謂的熱愛生命，似乎只是愛著過去自我的全能或完美姿態，而不是愛著美好與缺憾共存的此時此刻。 Will的選擇，也與片中不斷提到的電影《我的左腳》（My Left Foot）主角的精神背道而馳。《我的左腳》的主角患有腦性麻痺，只剩左腳可動，但他在自己受限的生命裡奮力綻出光芒。Will在片中也會模仿史蒂芬霍金，但霍金的人生是不向身體限制屈服的故事。相較起來，Will的決定就少了點動人的力量與說服力，反倒給了觀影者更多的遺憾。另外Will帶Lou體驗人生，讓Lou經驗過去從未享受過的生活，但那些用財富堆砌的生活與夢想，卻也讓人感覺有著距離。電影或許企圖打破傳統助人者與受助者之間的界線與框架，讓Will成為Lou的幫助者，這設計很好，但偏偏Will的財富就像原罪似的，讓故事落入另一種傳統框架：一個富家子弟改變了小鎮姑娘，反倒沒有新意了。不過，Will與Lou兩人的互動有趣、充滿火花，是觀影的享受。若是相較Lou與男友的互動，更可看出Will對Lou的在意與關心。Lou的男友雖然對Will充滿妒忌，但他在親密關係中的表現，只有「自我中心」四字可以形容。比如：他安排的情侶之旅，是配合自己的比賽行程；送給對方項鍊當生日禮物，上頭刻的卻只是自己的名字。這點Will就做得好太多了，他記得Lou說過的故事，他聽見Lou的期待與失落，他送了對Lou而言意義非凡的東西。這位千萬富翁送的禮物並不貴重，但卻是送到對方的心裡，那代表他對Lou的用心，代表他接納Lou的真實情感，以及他看見那繽紛色彩背後、女孩擁有的真性情。只是，我一直難放下的是，他看見了Lou未來的無限可能，卻沒看見自己的可能……
