Scanning Acoustic Microscope

In the last decade, a variety of characterization techniques based on acoustic phenomena have come into widespread use. Characteristics of matter waves such as their ability to penetrate optically opaque solids and produce image contrast based on acoustic impedance differences have made these techniques attractive to semiconductor and integrated circuit (IC) packaging researchers.These techniques can be divided into two groups. The first group includes techniques primarily applied to IC package inspection which take advantage of the ability of ultrasound to penetrate deeply and nondestructively through optically opaque solids. C-mode Acoustic Microscopy (C-AM) is a recently developed hybrid technique which combines the narrow-band pulse-echo piezotransducers of conventional C-scan recording with the precision scanning and sophisticated signal analysis capabilities normally associated with the high frequency Scanning Acoustic Microscope (SAM). A single piezotransducer is scanned over the sample and both transmits acoustic pulses into the sample and receives acoustic echo signals from the sample.

Tetraphenylmethane has emerged as a recurrent building block for advanced porous materials such as COFs, PAFs and hypercrosslinked polymers. Guided by a similar design principle, we have previously synthesized shape-persistent dendrimers with tetraphenylmethane nodes and ethynylene linkers. Here we report the generality of our approach by describing new dendritic architectures built from tetraphenylmethane. First, we prepared expanded dendrimers where the tetrahedral units are bonded through larger rigid rod spacers. Among the different synthetic strategies tested, the convergent route, with alternating steps of Pd-catalyzed Sonogashira coupling and alkyne activation by removal of TMS masking groups, efficiently afforded the first- and second-generation dendrimers. A second type of compounds having a linear diyne at the core is also described. The dendrimers of generations 1-2 were also synthesized by a convergent approach, with the diyne being assembled in the last step of the synthesis by a Glaser oxidative homocoupling of the corresponding dendrons bearing a terminal alkyne at the focal point. A third-generation dendrimer was also successfully prepared by a double-phase strategy.<br>

ABSTRACTCostume, dress code, animation, comics, legends, and manga, are inseparable parts of the cosplay costume. Those parts give fantasy and digital world discourse through costume style. Its spiritual domain stands on Japanese culture by being cultured through clothing. One of them, cosplay ideo- logy, reflects the self-imaging through social communities, as an e?ort for group and self-existence. Cosplay entity bridges fantasy and real world, presents designers’ expressions through the costume designs to show. This writing will be analyzed by using the main theories based on Dewitt H. Parker point of view, in The Principles of Aesthetics, which divides principles of aesthetics into three, they are: Principle of Organic Unity, Principle of Dominant Element, and Principle of Balance. Principle of organic unity indicates that cosplay clothing is an accumulation of design elements, to refer and mark a figure. Principle of dominant element, is accentuation, or the center of interest of a cosplay clothing design. Principle of balance, see placement and setting ornamentation applied to cosplay clothing.Keywords: cosplay clothing, principles of aesthetics, costume style, YogyakartaABSTRAKPakaian, dress code, animasi, dan manga, merupakan unsur yang tidak terpisahkan dalam pakaian cosplay. Unsur-unsur tersebut merupakan wacana dunia digital dan fantasi pada dunia pakaian. Ranah spiritualnya berp?ak pada kebudayaan Jepang yang dibudayakan melalui pakaian. Ideologi cosplay salah satunya menggambarkan pencitraan diri komuni- tas sosial, sebagai usaha untuk aktualisasi diri. Entitas cosplay mampu menjembatani du- nia fantasi dan realita, yang membelenggu keinginan manusia untuk bergaya. Tulisan ini akan dianalisis dengan teori pokok berdasarkan pandangan Dewitt H. Parker, dalam The Principles of Aesthetics, yang membagi prinsip estetika menjadi tiga, yaitu: prinsip kesatu- an organik, prinsip unsur dominan, dan prinsip keseimbangan. Prinsip kesatuan organik menunjukkan, bahwa pakaian cosplay merupakan akumulasi dari unsur-unsur desain, un- tuk merujuk dan menandai tokoh. Prinsip unsur dominan, merupakan aksentuasi, atau pusat perhatian dari sebuah desain pakaian cosplay. Prinsip keseimbangan, melihat penem- patan dan pengaturan ornamentasi yang diaplikasikan pada pakaian cosplay.Kata kunci: pakaian cosplay, prinsip estetika, gaya pakaian, Yogyakarta
