Large-quantity free-standing ZnO nanowires (2003)

Large-quantity (grams) one-dimensional ZnO nanowires of different sizes have been synthesized by a simple thermal evaporation of ZnO powder in a tube furnace at a temperature controlled to 1000–1200 °C and pressure to 1–2 Torr air. A mixture of ZnO and graphite powder was used as the source. Fine graphite flakes were used to promote the growth. The graphite flakes are the key for large-quantity yield and were easily removed by oxidation in flowing O2 at about 700 °C for 1–3 h. The scanning- and transmission-electron-microscopic studies show that the diameter and length of the nanowires vary from 20 to 100 nm and 0.5 to 10 μm, respectively. Room temperature photoluminescence studies found that the luminescent intensity depends on the processing conditions. A reduced band edge ultraviolet (380 nm) and deep-band green (520 nm) emission have been observed for these nanowires. Most importantly, the method can be extended to any other oxide nanowires that will be the building block of future nanoscale devices.
fMRI connectivity of expressive language in young children and adolescents (2018)

Studies of language representation in development have shown a bilateral distributed pattern of activation that becomes increasingly left-lateralized and focal from young childhood to adulthood. However, the level by which canonical and extra-canonical regions, including subcortical and cerebellar regions, contribute to language during development has not been well-characterized. In this study, we employed fMRI connectivity analyses (fcMRI) to characterize the distributed network supporting expressive language in a group of young children (age 4-6) and adolescents (age 16-18). We conducted an fcMRI analysis using seed-to-voxel and seed-to-ROI (region of interest) strategies to investigate interactions of left pars triangularis with other brain areas. The analyses showed significant interhemispheric connectivity in young children, with a minimal connectivity of the left pars triangularis to subcortical and cerebellar regions. In contrast, adolescents showed significant connectivity between the left IFG seed and left perisylvian cortex, left caudate and putamen, and regions of the right cerebellum. Importantly, fcMRI analyses indicated significant differences between groups at 3 anatomical clusters, including left IFG, left supramarginal gyrus, and right cerebellar crura, suggesting a role in the functional development of language.

A low-cost multi-modal medical imaging system with fringe projection profilometry and 3D freehand ultrasound (2020)

The growing need to perform surgical procedures, monitoring, and intervention of greater precision have led to the development of multimodal medical imaging systems. Multimodal images are a strategy to overcome the limitations of medical imaging technologies by combining the strengths of individual modalities or technologies. In this work, we propose a low-cost multimodal system that combines 3D freehand ultrasound with fringe projection profilometry to obtain information from the external and the internal structure of an object of interest. Both modalities are referred to a single coordinate system defined in the calibration to avoid post-processing and registration of the acquired images. The freehand ultrasound calibration results are similar to those previously reported in the literature using more expensive infrared tracking systems. The calibration reproducibility at the center point of the ultrasound image was 0.6202 mm for 8 independent calibrations. We tested our system on a breast phantom with tumors. Encouraging results show the potential of the system for applications in intraoperative settings.

Manganese Catalysis in Water Pollutants Abatement by Ozone (1995)

Abstract The catalytic influence of the Mn(II)oxalic acid system on the abatement by ozone of different organic pollutants in water is investigated. Results of the ozonation experiments performed in semibatch conditions reveal that even refractory aromatic pollutants are quickly removed by catalytic ozonation. Catalysts may be rendered ineffective by either high intrinsic reactivity of the organic pollutant in radical initiation by ozone and/or by strong radical scavenging effects of reacting mixtures. An interesting feature of the investigated system is that catalytic Mn(II) concentrations are similar to those found in some natural waters.

Qualitative Schulbuchanalyse zum Thema Linsenabbildung (2018)

Schulbucher bilden eine Brucke zwischen Lehrplan und Unterricht. An ihnen lassen sich lehrplankonforme und unterrichtstypische Zugange zu einem gegebenen Thema ablesen. Ziel der vorliegenden Untersuchung ist es, schulbuchgemase Zugange zur Linsenabbildung herauszuarbeiten. Es wird qualitativ analysiert, wie das Phanomen des Linsenbildes und das Modell des Strahls zueinander in Bezug gesetzt werden. Dementsprechend werden die Schritte der phanomenologischen Methode und der verallgemeinerten Modellmethode als Analyseraster auf die Strukturelemente der Schulbucher gelegt. Bei der Kategorisierung der nahegelegten Lernhandlungen und bei der diagrammatischen Darstellung der vorgesehenen Lernwege werden einige Schwachpunkte deutlich. Der schulbuchgemase Zugang zur Linsenabbildung sollte dementsprechend umstrukturiert, erganzt oder ersetzt werden.
Silicon Precipitation via Photoinduced Reaction Using Femtosecond Laser (2011)

Silicon precipitation inside a glass is an important technique for silicon photonics. We successfully precipitated silicon inside silicate glasses containing an Al metal film using femtosecond laser irradiation. First, the Al-inserted sandwiched glass was fabricated by the direct bonding method. The results of a tensile test indicated that the adhesive strength of the sandwich structure reached approximately 4 MPa. Next, femtosecond laser pulses were focused at the Al/glass interface in the sandwich structure. A transmission electron microscopy photograph at the focus of the laser showed that the Al particles were dispersed into the glass substrate to a depth of approximately 2 microm from the initial Al layer. In addition, Raman spectra indicated that silicon had formed at the interface between the glass and Al film after the laser irradiation. The morphology or the particle size of the precipitated silicon was successfully modified by changing the repetition rate or the pulse energy of the laser.
High-temperature electrical conductivity and thermal stability of FeCl3 doping in carbon nanotube tapes (2021)

Abstract We report on the development of high-conductivity carbon nanotube (CNT) tapes with high stability at elevated temperatures (220 °C) by a two-step FeCl 3 -doping process at ambient pressure. Raman spectroscopy, electron microcopy, and thermogravimetric analysis reveal that this robust behavior is ascribed to the retentiveness of the dopants in the CNTs. These results advance the development of CNT tapes for practical cable applications under harsh conditions.
Acetylcholinesterase Enzyme Inhibitory Effects of Amaryllidaceae Alkaloids (2004)

Twenty-three Amaryllidaceae alkaloids having several different ring types were evaluated for their acetylcholinesterase enzyme (AChE) inhibitory activity. The alkaloid 1- O-acetyllycorine (IC50 : 0.96 +/- 0.04) showed significant AChE inhibitory activity. In addition, crinine (IC50 : 461 +/- 14), crinamidine (IC50 : 300 +/- 27), epivittatine (IC50 : 239 +/- 9), 6-hydroxycrinamine (IC50 : 490 +/- 7), N-desmethyl-8alpha-ethoxypretazettine (IC50 : 234 +/- 13) N-desmethyl-8beta-ethoxypretazettine (IC50 : 419 +/- 8), lycorine (IC50 : 213 +/- 1), and 1,2-di- O-acetyllycorine (IC50 : 211 +/- 10) had weak activity. Lycorine-type alkaloids were the most active alkaloids with 1- O-acetyllycorine exhibiting inhibitory effects two-fold more potent than that of galanthamine.
High-valent manganese(v)–oxo porphyrin complexes in hydride transfer reactions (2008)

Hydride transfer from dihydronicotinamide adenine dinucleotide (NADH) analogues to trans-dioxomanganese(v) porphyrin complexes proceeds via proton-coupled electron transfer, followed by rapid electron transfer.
Macropod studies at Wallaby Creek. 4. Home range and movements of the red-necked wallaby (1987)

Red-necked wallabies were observed to live in small home ranges, the locations of which changed little from season to season and from year to year. Home ranges were situated in places where open areas, used for feeding, lay close to the cover offered by dense vegetation and gullies. The home ranges of medium-sized males tended to be peripheral to areas preferred by females, and by larger and smaller males. Females tended to shift their home ranges towards the edges of large beds of cover as their infants left the pouch. The home ranges of males were larger than those of females, and body size and homerange size were positively correlated among males. Females used larger home ranges in winter than in summer.
LocaLudo (2014)

In this paper, we describe the design and outcomes of LocaLudo, a playful and card-based workshop that aims to involve families in the design of interactive architecture. Family members, both children and adults, were invited to build upon local experiences for informing the design of concepts that allow interaction between the house, its residents, and the neighborhood. While the creation of such concepts proved challenging, we found that an open and playful approach, and suggesting the possible use of technologies aided participants in this process. Several recurring themes were identified in the generated concepts: stimulating social contact, spreading information, reacting to negative events, and solving practical problems.
SiC Epitaxial Reactor Cleaning by ClF<sub>3</sub> Gas with the Help of Reaction Heat (2020)

A silicon carbide epitaxial reactor cleaning process was designed accounting for the exothermic reaction heat between silicon carbide and chlorine trifluoride gas. To avoid the peeling of the susceptor surface coating film, the spontaneous temperature increase due to the exothermic reaction heat was moderated by adding the nitrogen gas. The particle-type silicon carbide deposition could be effectively removed without causing any damage of susceptor.
CMOS data output buffer for integrated memories (1992)

A data output buffer for CMOS integrated memories is presented. Output presetting techniques together with a suitable driving of the final transistors are used. The switching noise on supply lines is minimised while high operation speed is preserved. A buffer for a 0.8 μm EPROM process has been designed using the proposed approach.
Analyzing Java software by combining metrics and program visualization (2002)

Shimba, a prototype reverse engineering environment, has been built to support the understanding of Java software. Shimba uses Rigi and SCED to analyze, visualize, and explore the static and dynamic aspects, respectively, of the subject system. The static software artifacts and their dependencies are extracted from Java byte code and viewed as directed graphs using the Rigi reverse engineering environment. The static dependency graphs of a subject system can be annotated with attributes, such as software quality measures, and then be analyzed and visualised using scripts through the end user programmable interface. Shimba has recently been extended with the Chidamber and Kemerer suite of object oriented metrics. The metrics measure properties of the classes, the inheritance hierarchy, and the interaction among classes of a subject system. Since Shimba is primarily intended for the analysis and exploration of Java software, the metrics have been tailored to measure properties of software systems using a reverse engineering environment. The static dependency graphs of the system under investigation are decorated with measures obtained by applying the object oriented metrics to selected software components. Shimba provides tools to examine these measures, to find software artifacts that have values that are in a given range, and to detect correlations among different measures. The object oriented analysis of the subject Java system can be investigated further by exporting the measures to a spreadsheet.
Effect of Reaction Solvent on the Hydrogenation of Isophthalonitrile for Meta‐Xylylendiamine Preparation (2007)

Abstract This study focused on the effects of reaction solvent on the hydrogenation of isophthalonitrile (IPN) to produce m‐Xylylenediamine (MXDA) over Ni‐based commercial catalyst. The hydrogenation was carried out using various reaction solvents such as 1‐methylimidazole, mesitylene, benzyl ether and isopropanol under various reaction conditions. It was observed that 1‐methylimiazole outperformed the other reaction solvent, exhibiting a high MXDA yield and producing a low concentration of undesirable products.
Hot-Spot Detection System with Correction of Operating Point for PV Generation System (2017)

Currently, the production and the number of installations of PV (photovoltaic) modules have been increasing rapidly because of a feed-in tariff in Japan. Accordingly, the number of failures has also increased. Many failures are a result of the Hot-Spot phenomenon in which defective cell becomes hot when shadow occurs on the cell. On the other hand, if shadow occurs on normal cell, there are cases that P&O method that is MPPT (maximum power point tracking) control method incorporated in conventional PV system cannot track maximum power point and generated power decreases. The correspondence is required rapidly if these trouble occur. However, conventional PV system monitors generated power, correspondence is impossible by monitoring generated power. Previously, the authors developed real time Hot-Spot detection system that incorporates into PCS (power conditioning system). Thus, the authors developed plug-in type Hot-Spot monitoring system that includes "PV peak shift method" and confirmed effectiveness of the system in this time. "PV peak shift method" loads "Scan method" that is MPPT control method and measures I-V (current-voltage) characteristic by changing voltage of module from open to short by "Scan method" on a regular basis. The developed Hot-Spot monitoring system uses slope of I-V characteristic of PV module. Inserting developed system into already installed PV system, Hot-Spot can be easily monitored in real time and PV system can be operated at maximum power point.
Adsorption of arsenic to magnetite nanoparticles: Effect of particle concentration, pH, ionic strength, and temperature (2008)

Little work has been conducted on the adsorption of arsenic to the mixed iron [Fe(II)/(III)] oxide magnetite and the effect that environmental parameters, such as pH, ionic strength, and temperature, have on adsorption. Magnetite nanoparticles are unique because of their affinity for both arsenate and arsenite and increased adsorption capacity from their bulk counterparts. This article shows the effect of various magnetite nanoparticle concentrations on arsenic adsorption kinetics. The adsorption data show the ability of the magnetite nanoparticles to remove arsenate and arsenite from solution in both synthetic and natural waters, and the data fit a first-order rate equation. Because of the increased surface area of these particles, less than 1 g/L of magnetite nanoparticles was needed. The results suggest that arsenic adsorption to the nanoparticles was not significantly affected by the pH, ionic strength and temperature in the ranges tested, which are typical of most potable water sources.
Antimicrobial Activity of the Essential Oil Obtained from Roots and Chemical Composition of the Volatile Constituents from the Roots, Stems, and Leaves of Ballota nigra from Serbia (2009)

The chemical composition of essential oils obtained from the roots, stems, and leaves of Ballota nigra, growing in Serbia, was investigated by gas chromatography/mass spectrometry analyses. Kovats indices, mass spectra, and standard compounds were used to identify a total of 115 individual compounds. The plant produces two types of essential oils. Oils derived from stems and leaves were sesquiterpene rich (78.17% and 88.40%, respectively), containing principally beta-caryophyllene, germacrene D, and alpha-humulene, present in appreciable amounts. In contrast, oil derived from the root was dominated by p-vinylguiacol (9.24%), borneol (7.51%), myrtenol (7.13%), trans-pinocarveol (5.22%), pinocarvone (4.37%), 2-methyl-3-phenylpropanal (4.32%), and p-cymen-8-ol (4.30%). Essential oil obtained from the roots was evaluated for the antimicrobial activity against seven bacterial species and one fungi.

Isolation and Some Properties of the Genes Coding for Histone Proteins (1974)

The DNA coding for histone proteins, together with the intervening spacer DNA, has been isolated from the sea urchin, Psammechinus miliaris, by repeated centrifugation on CsCl-asctinomycin gradients. The biophysical data show that a major portion of the spacer is 37% G+C and very divergent in sequence, while the DNA segments coding for histone proteins are high in G+C and have diverged to a lesser extent within the species.
Doping-evolution of the superconducting gap in single crystals of (Ca1−xLax)10(Pt3As8)(Fe2As2)5superconductor from London penetration depth measurements (2014)

The doping-evolution of the superconducting gap structure in iron-based superconductor (CaLa x )10(Pt3As8)(Fe2As2)5 (x = 0.04, 0.06, 0.09, 0.11, and 0.18) was probed by high—resolution measurements of the London penetration depth, . The samples spanned compositions from underdoped to slightly overdoped with superconducting critical temperatures, T c , from 12.7 K (x = 0.04) through (optimal) 23.3 K (x = 0.11) to 21.9 K (x = 0.18). The low-temperature variation (up to 0.3 T c ) of was analysed using a power-law function, . For compositions close to the optimal doping, (x = 0.09, 0.11, and 0.18), characterized by , shows a tendency to saturation, indicative of a full gap on the Fermi surface. Fitting over the lowest temperature range () gives n = 2.6. This value is well outside the range expected for the line-nodal superconductor. The exponent n decreased to in the two most underdoped compositions x = 0.04 (T c = 12.7 K) and 0.06 (T c = 18.2 K), implying the development of a notable gap anisotropy revealed by the enhanced influence of pair-breaking scattering. This decrease is accompanied by a significant increase of the total variation of the penetration depth in a fixed temperature interval (e.g., ). Both the decrease of the exponent and the increase of the absolute value of in the underdoped regime are similar to the observations in other charge-doped iron-based superconductors, such as doped BaFe2As2 and NaFeAs, suggesting a universal behavior in iron-based superconductors.
