To investigate the mechanical behaviour of laminated glass with the elasto-viscoplastic ionomer interlayer SentryGlas® by DuPont, an experimental program was executed on full-scale glass laminates. The results of this research improved the insight in the complex mechanical behaviour of this stiff interlayer. More spec…
The effect of ultraviolet (UV) curing on film properties of porogen based porous SiOC (P-SiOC) film was investigated. The P-SiOC films were prepared by plasma-enhanced chemical vapor deposition (PECVD) using alkoxysilane and porogen (hydrocarbon). UV curing time was changed from 0 s to 1000 s. The variation of the k v…
Bilayers of Ru (7 nm)/WN x (8 nm) prepared by sputtering were investigated as diffusion barriers between Cu and Si, and their performances were compared as a function of N 2 flow rate during the deposition of WN x . The Ru/WN x bilayer diffusion barriers were stable upon annealing at up to at least 650 °C for 30 min w…
To investigate the long-lasting green afterglow from Ho added CaGa 2 S 4 :Eu compounds, photoluminescence (PL) and photoluminescence excitation (PLE) spectra are measured as a function of Ho concentration by keeping Eu one at 0.1 and 0.5 mol %. As Ho concentration increases, PL intensity of Eu decreases. PL from Ho at…
The first-principles calculations of the lattice dynamics of the TlGaSe 2 ternary semiconductor compound are presented in this paper. Calculations were performed using open-source code ABINIT on the basis of the density functional perturbation theory within the plane-wave pseudopotential approach. Results on the frequ…
A low-friction seal developed by Bal Seal Engineering Inc is helping design engineers meet strict weight, wear and performance requirements in gimbal-type units or “pods” used on aircraft.
The bald disappearance of barrier metal had been observed on the wafer after Cu chemical mechanical planarization (CMP) processing. It was speculated that this phenomenon occurs because the excessively oxidized Ta by electrochemical reaction with Cu ion was removed more easily than the normal Ta oxide around it. The i…
There were different heat treatments to Cu-Zn-Al shape memory alloy. Cement-based smart lost-circulation control material was prepared by the method of rolling agglomeration. And indoor simulation experiment was carried out. The results show that the heat treatment temperature is 800°C, the quenching medium is the boi…
Antireflection (AR) coating systems are very important technology for optoelectronic devices. The optical characteristics of the system can be regulated by external electric or thermal field, and designed broadband ultra low reflection coating systems. It is investigated optical properties of multilayer AR coatings ba…
As radiation levels around the crippled Fukushima Dai-ichi nuclear plant in Japan increase, the Japanese people as well as individuals around the world have expressed fear of radiation that some experts say could be more unhealthy than the levels of leaked radioactive contamination. This article addresses why individu…

235 Objectives To quantitatively evaluate the biodistribution of novel CdTeSe/109CdZnSe radio quantum dots (rQDs). These rQDs are novel and would mimic the biodistribution of native QDs because the radioisotope is incorporated into the QD’s structure, as opposed to being chemically chelated. Methods We synthesized nea…
A recently developed precursor, AbaCus, has been evaluated for use in ultra-low temperature copper deposition by PEALD. Film adhesion, platability and process window evaluation demonstrate a strong capability of this precursor to overcome current metallization challenges.
The minority carrier diffusion length has been identified as one of the most important parameters that governs the performance of a solar cell device. In this work thin films of SnS have been grown by the thermal evaporation of high purity tin sulphide onto cadmium sulphide/indium tin oxide/ glass substrates to fabric…
The objective of the present article is to examine whether current regulations at the European level are capable of adequately controlling the risks associated with engineered nanomaterials of anthropogenic origin (ENM) in food products. In this context it is crucial to examine closely the Novel Food Regulation (EC) 2…
Bernard O'Donoghue's poem 'What's the Time, Mr Wolf?' in his collection Gunpowder (1995) opens with a snatch of hearsay about the amorphous inorganic material that casts its lustre on our lives: Glass, someone once told me, is a liquid Of such density that its sluggish Downward seep takes centuries to work, So medieva…
Application of microwave radiation for the treatment of two different series of prepared hexagonal barium ferrite was done. The treated hexagonal barium ferrite was prepared by sol gel autocombusion technique. The first series was calcinated at 850°C for 4 hours while the other was calcinated at 950°C for 5 hours. Bot…
At first, an unsaturated monomer bearing luminescence group, acryloylfluorescein was synthesized from fluorescein and acryloyl chloride by simple method and was identified by IR, MS and (1)H NMR spectra. The homopolymer of monomer was obtained with solution polymerization and the average molecular weights obtained was…
In this paper, the morphological transformations in Hibiscus sabdariffa (Roselle) stem fibre on graft copolymerisation with acrylonitrile (AN) as principal monomer and its binary mixture with 2–vinyl pyridine (2–VP), styrene (Sty), and butyl acrylate (BA), using a ceric ammonium nitrate–nitric acid initiator system, a…
오늘날 폐기물문제는 국내외적으로 중요한 국가과제로 자리매김하고 있다. 이와 같은 폐기물문제의 근원은 대량생산ㆍ대량소비ㆍ대량폐기형의 경제활동에 의해 질ㆍ양 양면에 걸쳐서 환경부하가 증대하고 있는 것에 있다고 할 수 있을 것이다. 따라서 「대량생산ㆍ대량소비ㆍ대량폐기형의 사회에서 순환형사회로의 전환」은 이제 피할 수 없는 시대적 요청이 되고 있다. 한편, 일본에서는 2000년 6월에 「순환형사회형성추진기본법」이 제정되어 순환형사회의 형성에 향한 움직임이 구체화하게 되었다. 특히 폐기물처리법과 관련하여서는 그동안의 문제점을 근거로 하여 2010년 5월 19일 개정된 법률이…
