阅读全文Catalyst fabrication The catalyst has been fabricated in a stepwise manner through successive surface modifications of h-BN nanosheets, as displayed in Fig. 2. In the initial step, hydroxyl functional...
阅读全文Materials All the reagents including Tributylphosphate (TBP), acetonitrile (ACN), ethyl acetate, hexane, toluene, zirconyl chloride octahydrate (ZrOCl2. 8H2O), NaOH were purchased from Sigma Aldrich, ...
阅读全文TORAY日前開發出一款可應用於食品製造與生質領域之精製、濃縮工程用高耐久性中空纖維超濾膜模組,並已展開商樣供應。新製品將可有助於大幅度減少製造過程中產生的二氧化碳。 中空纖維膜因高面積利用效率,也就是分離...
阅读全文從廢舊電子設備或家用電器中取出有用金屬並予以再利用的「都市礦山」因東京奧運的獎牌而受到矚目。若是利用微生物回收金屬的話,或將能更順利地進行再利用。而日本廣島大學即展開研究,欲透過細菌收集混入海水或工廠...
阅读全文Lasers concentrate light into extremely bright beams that are useful in a variety of domains, such as broadband communication and medical diagnostics devices. About ten years ago, extremely small and ...
阅读全文The device would also be useful for studying electrical activity inside neurons. This is a direction that the team is looking to explore next. Down the line, the researchers plan to use their device t...
阅读全文As proof of concept, the team integrated ultra-thin organic photovoltaic and LED-light modules that were printed on separate films and connected by five additional polymer films. The devices withstood...
阅读全文More than 70 years ago, Soviet physicists Leonid Mandelstam and Igor Tamm deduced theoretically this minimum time for transforming the wave function. Physicists at the University of Bonn and the Techn...
阅读全文The new concept for seeing where the tweezers are reaching is to analyze the defocused laser-scattered light on a fast camera behind the object, which serves as a feedback signal. The more asymmetrica...
阅读全文"We aimed to design materials that allowed for the introduction of a large number of interstitial oxygens into their structure and showed high conductivity at intermediate and low temperatures. Additi...
阅读全文Peter Bøggild emphasises that these three problems have not been solved with the new method alone: “We have taken a very significant step. We have converted a laminating machine into a so-called rol...
阅读全文Ge thin films can be grown using the solid-phase crystallization technique. These thin films are polycrystalline, meaning they are made up of many Ge crystals. In general, larger crystals lead to grea...
阅读全文"It is well known that the carrier density in graphene is highly sensitive to external perturbations. Such change in carrier density is reflected in the drain current. Although there was some attempt ...
