Fiber Optic Detectors• Both photodiode and integrating sphere designs available • 818-xx-L-FC/DB Series are new low cost fiber optic photodiode detectors• 818-IS-1 and 918D-IS Series utilize integrating spheres,enabling accurate and polarization independent measurements• Lower calibration uncertainty than competitionNew! 818-xx-L-FC/DB Photodiode Fiber Optic Detectors are a low costalternative to the 818-IS or 918D-IS Series.The detectors are based on the industry standard 818 Series detectors with a new 884-FC fiber optic adapter mounted on it. UV Silicon, Silicon, Germanium, and InGaAs versions are introduced. FC/APC and SMAconnectors can easily accommodated by replacing the 884-FC with 884-FCA and 884-SMA,respectively.Model 818-IS-1 and 918D-IS-1 Universal Fiber Optic Sensors use a 1" symmetricalintegrating sphere to ensure the most accurate calibration possible, regardless of the fiber type measured. The integrating sphere uses a dual detector design, with special optics that improve temperature sensitivity markedly from ordinary detectors, with the wavelength range of 400–1650 nm. The 918D-IS-IG uses a single InGaAS detector (800-1650 nm) while the 918D-IS-SL uses a single Si detector (400-1100nm). The calibration data is encoded in a calibration module integral to the electrical connector. The 818-IS-1 is compatible with Newport's legacy power meters utilizing calibration modules, while the 918D-IS versions have an integral DB15 connector and are compatible with Newport's new power meters.A variety of adapters for connector-terminated fibers are provided, and plug into the detector’s front port. The rear port is designed to measure light from straight and angle cleaved bare fibers, using Newport’s FP3-FH1 bare fiber holder. A complete kit of adapters is included with each detector, together with a rugged carrying case.To maintain accuracy and guarantee performance Newport recommends annualrecalibration. Newport offers calibration service, including the new ANSI Z450.3 compliant calibration.Which Connector Type to Choose?An example of the DB15 (left) and the 8-pin DIN (right) style calibration module, respectively.The 918D-IS series models come with the DB15 calibration module permanently attached to the cable. The 818-xx-L-FC/DB models with /DB suffix come with a detachable BNC/DB15 calibration module that provides direct compatibility with Newport's active power meters. The 818-IS-1 model comes with a round 8-pin mini-DIN calibration module that provides compatibility with legacy Newport power meters. In both cases, the adapters contain the detector calibration data, model number,serial number and calibration date for seamless operation with thepower meter.

Noble metal nanocatalysts, renowned for their exceptional catalytic activity and stability, play a crucial role in DMFCs. Among these catalysts, Pt- and Pd-based nanocatalysts are widely recognized as the most effective catalysts for the electrochemical methanol oxidation reaction (MOR), which is the key half-cell reaction in DMFCs. However, due to the high cost of Pt- and Pd-based materials, there is a strong desire to further enhance their catalytic performance. One of the most promising approaches for it is to develop noble metal-based alloy nanocatalysts, which have shown great potential in improvingelectrocatalytic activity. Notably, advancements in phase engineering of nanomaterials (PEN) have revealed that noble metal-based nanomaterials with unconventional phases exhibit superior catalytic properties in various catalytic reactions compared to their counterparts with conventional phases. To obtain noble metal-based nanocatalysts with unconventional crystal phases, wet-chemical epitaxial growth has been employed as a facile and effective method, utilizing unconventional-phase noble metal nanocrystals as templates. Nevertheless, epitaxially growing bimetallic alloy nanostructures withunconventional crystal phases remains a challenge, impeding further exploration of their catalytic performance in electrochemical reactions such as MOR. In this study, we utilize 4H hexagonal phase Au (4H-Au) nanoribbons as templates for the epitaxial growth of unconventional 4H hexagonal PdFe, PdIr, and PdRu, resulting in the formation of 4H-Au@PdM (M = Fe, Ir, and Ru) core-shell nanoribbons. As a proof-of-concept application, we investigate the electrocatalytic activity of the synthesized 4H-Au@PdFe nanoribbons towards MOR, which exhibit a mass activity of 3.69 A·mg Pd−1, i.e., 10.5 and 2.4 times that of Pd black and Pt/C, respectively, placing it among the best Pd- and Pt-based MOR electrocatalysts. Our strategy opens up an avenue for the rational construction of unconventional-phase multimetallic nanostructures to explore their phase-dependent properties in various applications.Key Words: Phase engineering of nanomaterials; Crystal phase; 4H phase; Pd-based alloy;Methanol oxidation reaction在4H晶相Au纳米带上外延生长非常规晶相4H-Pd基合金纳米结构用于高效甲醇电催化氧化汪婕1,2,†，刘贵高2,7,†，韵勤柏3，周希琛3，刘效治6，陈也8，程洪飞2，葛一瑶3，黄京韬2，胡兆宁2，陈博3，范战西3,4,5，谷林9，张华3,4,5,*1西华大学材料科学与工程学院，流体与动力机械教育部重点实验室，成都 6100392南洋理工大学材料科学与工程学院可编程材料中心，新加坡 639798，新加坡3香港城市大学化学系，香港4香港城市大学，国家贵金属材料工程研究中心香港分中心，香港5香港城市大学深圳研究院，广东深圳 5180576中国科学院物理研究所，北京凝聚态物理国家实验室，北京 1001907南京理工大学化学化工学院，国家特种超细粉体工程研究中心，南京 2100948香港中文大学化学系，香港9清华大学材料科学与工程系，北京国家电子显微镜中心与先进材料实验室，北京 100084摘要：Pd基合金纳米材料通常具有传统的面心立方(fcc)晶相。
