pH-mediated synthesis of monodisperse gold nanorods with quantitative yield and molecular level insight

Nano Research 2021年第4期14卷 1167-1174页

Although gold nanorods(GNRs)have been produced with different dimensions and aspect ratios,the current synthesis methods through seed-mediated growth are far from ideal,for instance,the quality(rod yield)and the quantity(gold conversion)cannot be simultaneously *** critically,there is no molecular level understanding of the growth ***,we solved the problem by employing the stoichiometric ratio of reactants and tuning the reactivity of the reductant through adjusting the initial pH value of the growth solution to achieve both good quality and high quantity *** also extended our strategy to other enols besides ascorbic acid,such as phenolic compounds,and found that the optimal pH for GNRs synthesis depends on the structure of the individual *** mechanistic insight greatly enriches the toolbox of reductants for GNRs growth and makes it possible to synthesize GNRs at both acidic and basic *** interesting phenomenon is that for most of the phenolic compounds we tested,the morphology of the final products follows the same sphere-rod-sphere trend as the initial pH value of the reaction increases,whether it is under acidic or basic conditions,which cannot be explained by any previously proposed *** effect of pH is mainly attributed to the regulation of the reduction potential of the reductants,and thus the reaction rate.A model has been proposed to explain the dependence of anisotropic growth of GNRs on the concentration gradient of reactants around the seeds,which is decided by both the reaction rate and diffusion rate.

Distal triceps injuries(including snapping triceps):A systematic review of the literature

引用

World Journal of Orthopedics 2017年第6期8卷 507-513页

作者： Kimberley Shuttlewood James beazley Christopher D Smith Royal Devon and Exeter Hospital

AIM To review current literature on types of distal triceps injuryand determine diagnosis and appropriate *** We performed a systematic review in PubM ed, Cochrane and EMBASE using the terms distal triceps tears and snapping triceps on the 10 th January 2017. We excluded all animal, review, foreign language and repeat papers. We reviewed all papers for relevance and of the papers left we were able to establish the types of distal triceps injury, how these injuries are diagnosed and investigated and the types of management of these injuries including surgical. The results are then presented in a review paper *** Three hundred and seventy-nine papers were identified of which 65 were relevant to distal triceps injuries. After exclusion we had 47 appropriate papers. The papers highlighted 2 main distal triceps injuries: Distal triceps tears and snapping triceps. Triceps tear are more common in males than females occurring in the 4th-5th decade of life and often due to a direct trauma but are also strongly associated with weightlifting and American football. The tears are diagnosed by history and clinically with a palpable gap. Diagnosis can be confirmed with the use of ultrasound(US) and magnetic resonance imaging. Treatment depends on type of tear. Partial tears can be treated conservatively with bracing and physio whereas acute tears need repair either open or arthroscopic using suture anchor or bone tunnel techniques with similar success. Chronic tears often need augmenting with tendon allograft or autograft. Snapping triceps are also seen more in men than women but at a mean age of 32 years. They are characterized by a snapping sensation mostly medially and can be associated with ulna nerve subluxation and ulna nerve symptoms. US is the diagnostic modality of choice due to its dynamic nature and to differentiate between snapping triceps tendon or ulna nerve. Treatment is conservative initially with activity avoidance and if that fails surgi

应该找到一种方法使电动汽车的声音和谐起来当交通信号灯变绿时,发动机加速的咆哮声,摩托车从车流中冲出的音浪,公共汽车呼啸而过——在任何一条繁忙的街道上,最无法忽视的便是车流的噪音。一个世纪以来,内燃机的声音成为城市生活的主要音响,但这正在全球范围内逐渐改变。澳大利亚正在制定电动汽车的噪音标准,可能会遵循欧盟或美国的类似规则。然而,电动汽车到底会有什么样的声音,是来源于汽车制造商的创造与设计,而每家公司都在做不同的事情。
