Study of the Hole Transport Processes in Solution‐Processed Layers of the Wide Bandgap Semiconductor Copper(I) Thiocyanate (CuSCN)
Authors: Pattanasattayavong Pichaya , Mottram Alexander D. , Yan Feng , Anthopoulos Thomas D.
Published: October 2015

Wide bandgap hole‐transporting semiconductor copper(I) thiocyanate (CuSCN) has recently shown promise both as a transparent p‐type channel material for thin‐film transistors and as a hole‐transporting layer in organic light‐emitting diodes and organic photovoltaics. Herein, the hole‐transport properties of solution‐processed CuSCN layers are investigated. Metal–insulator–semiconductor capacitors are employed to determine key material parameters including: dielectric constant [5.1 (±1.0)], flat‐band voltage [−0.7 (±0.1) V], and unintentional hole doping concentration [7.2 (±1.4) × 1017 cm−3]. The density of localized hole states in the mobility gap is analyzed using electrical field‐effect measurements; the distribution can be approximated invoking an exponential function with a characteristic energy of 42.4 (±0.1) meV. Further investigation using temperature‐dependent mobility measurements in the range 78–318 K reveals the existence of three transport regimes. The first two regimes observed at high (303–228 K) and intermediate (228–123 K) temperatures are described with multiple trapping and release and variable range hopping processes, respectively. The third regime observed at low temperatures (123–78 K) exhibits weak temperature dependence and is attributed to a field‐assisted hopping process. The transitions between the mechanisms are discussed based on the temperature dependence of the transport energy.

Published: October 2015

A detailed atomic scale description of the interfaces between cerium oxide and metals is necessary for a clear understanding of interfacial interactions, and it may open the way to the optimization of the properties of the combined material in view of its applications. In this study the interface between cerium oxide epitaxial films and the (111) surface of platinum is studied by aberration‐corrected scanning transmission electron microscopy and by ab initio density functional theory calculations. Local modifications of the registry between the cerium oxide and platinum lattices and the occurrence of nanometric platinum islands at the interface are detected by high‐angle annular dark field imaging. Moreover, the preferential adsorption sites of Ce and O atoms at the interface are determined by a comparison of the images acquired in annular bright‐field mode and the results of density functional theory calculations. The presence of a non‐negligible concentration of Ce3+ ions at the interface is detected by electron energy loss spectroscopy and it is rationalized in terms of interfacial charge transfer as evidenced by the calculations. This work provides an insight into the atomic and electronic structure of the technologically relevant CeO2/Pt interface and it helps to clarify the properties of the combined material.
One‐Step Hydrothermal Tailoring of NiCo2S4 Nanostructures on Conducting Oxide Substrates as an Efficient Counter Electrode in Dye‐Sensitized Solar Cells
Authors: Khoo Si Yun , Miao Jianwei , Yang Hong Bin , He Ziming , Leong Kam Chew , Liu Bin , Tan Timothy Thatt Yang
Published: October 2015

A one‐step in situ tailoring of NiCo2S4 nanostructures is demonstrated on fluorine‐doped tin oxide (FTO) as Pt‐free counter electrodes (CEs) for dye‐sensitized solar cells (DSSCs) with performance surpassing that of a conventional Pt‐sputtered CE. An interconnected NiCo2S4 nanosheet network is successfully constructed on the FTO glass via a hydrothermal method, attributed to the synergistic effect of structure‐directing hexamethylenetetramine and L‐cysteine. A growth mechanism is proposed, and the effects of nanostructures and sulfur atomic percentages on the electrocatalytic performance are discussed in depth. A DSSC with the optimized interconnected NiCo2S4 nanosheet CE exhibits higher power conversion efficiency (7.22%) compared to that with a conventional Pt‐sputtered CE (6.87%) due to excellent charge transport properties and enhanced electrocatalytic activity of the NiCo2S4 nanostructures. This work showcases the strong potential of nanostructured ternary chalcogenides, which are composed of earth‐abundant elements and prepared through a single‐step hydrothermal process without tedious posttreatments, to reduce the dependence of platinum in DSSCs and other electrochemical devices.

Published: October 2015

Transient ischemic attack (TIA) can be difficult to diagnose. Episodes of acute atypical or nonfocal neurological symptoms, referred to as transient neurological attack (TNA), are as prevalent as TIAs. Diffusion‐weighted imaging (DWI) provides evidence of acute cerebral ischemia in a third of TIA patients. We now report that DWI shows acute ischemia in 23% of patients clinically diagnosed as TNA by experienced stroke neurologists. This questions the accuracy of clinically diagnosing TIA and suggests added value for early magnetic resonance imaging after an episode of acute onset atypical or nonfocal neurological symptoms.

Published: October 2015

Objective

In the present report, the correlations between ex vivo high‐resolution imaging and specific histological and ultrastructural patterns in type II focal cortical dysplasia (FCD) have been studied to explain the differences in the magnetic resonance imaging (MRI) detection of dysplasia and to contribute to the presurgical imaging evaluation of this pathology.

Methods

Surgical specimens from 13 patients with FCD IIa/b were submitted to 7T MRI scanning, and then analyzed histologically and ultrastructurally to compare the results with the MRI findings. Region of interest (ROI)‐based measures on T2‐weighted images (T2wi) were quantitatively evaluated in the lesion and in adjacent perilesional gray and white matter.

Results

Matched histological sections and 7T T2wi showed that the core of the lesion was characterized by patchy aggregates of abnormal cells and fiber disorganization related to inhomogeneity of intracortical signal intensity. The quantitative approach on T2wi can help to distinguish the lesions and perilesional areas even in a clinical MRI‐negative case. The ultrastructural study showed that the strong signal hyperintensity in the white matter of FCD IIb was related to a dysmyelination process associated with severe fiber loss and abnormal cells. Less severe histopathological features were found in FCD IIa, thus reflecting their less evident MRI alterations.

Interpretation

We suggest that white matter abnormalities in type IIb FCD are due to defects of the myelination processes and maturation, impaired by the presence of balloon cells. To reveal the presence and the border of type II cortical dysplasia on MRI, a quantitative ROI‐based analysis (coefficient of variation) is also proposed. ANN NEUROL 2016;79:42–58
From N‐Nitro to N‐Nitroamino: Preparation of High‐Performance Energetic Materials by Introducing Nitrogen‐Containing Ions
Authors: Yin Ping , Shreeve Jean'ne M.
Published: October 2015

In the design of energetic materials, high energetic performance and good molecular stability are two main goals. Energetic functionalization which strives for maximum energy often results in unstable chemical bonds and causes safety problems in practical production and storage operations. In this work, N‐nitro‐ and N‐nitroamino‐functionalized mono‐ and bis(1,2,4‐triazoles) were synthesized and characterized by infrared, and multinuclear NMR spectra, and elemental analyses. The N‐nitroamino‐functionalization strategy was employed for bis(imidazole), leading to high density compound 14 (2.007 g cm−3 at 100 K; 1.94 g cm−3 at room temperature) and energetic salt 15. While N‐nitro‐functionalized products are thermally unstable and highly moisture sensitive, N‐nitroamino‐functionalized energetic salts, which are comprised of additional nitrogen‐containing ions, exhibit good density, moderate to excellent structural stabilities, and high performance.

Published: October 2015

Fluorescent proteins are transformative tools; thus, any brightness increase is a welcome improvement. We invented the “vGFP strategy” based on structural analysis of GFP bound to a single‐domain antibody, predicting tunable dimerization, enhanced brightness (ca. 50 %), and improved pH resistance. We verified all of these predictions using biochemistry, crystallography, and single‐molecule studies. We applied the vsfGFP proteins in three diverse scenarios: single‐step immunofluorescence in vitro (3× brighter due to dimerization); expression in bacteria and human cells in vivo (1.5× brighter); and protein fusions showing better pH resistance in human cells in vivo. The vGFP strategy thus allows upgrading of existing applications, is applicable to other fluorescent proteins, and suggests a method for tuning dimerization of arbitrary proteins and optimizing protein properties in general.

Published: October 2015

An unusual iron transfer and carbon–carbon coupling take place in gas‐phase ionized mixtures containing ferrocene and dichloromethane. Ferrous chloride and the protonated benzenium ion are eventually formed by a thermal and efficient reaction, through stable intermediates that undergo a remarkable reorganization. The mechanism of the concerted iron extrusion, carbon–chlorine bond activation and carbon–carbon bond formation is elucidated by electronic structure calculations that show the crucial role of iron.
SECRETION OF LIPASES IN THE DIGESTIVE TRACT OF THE CRICKET Gryllus bimaculatus
Authors: Weidlich Sandy , Hoffmann Klaus H. , Woodring Joseph
Published: October 2015

Little is known concerning the sites and the ratios of the lipase secretions in insects, therefore we undertook an examination of the lipase secretion of fed and unfed adult female Gryllus bimaculatus. The ratio of triacylglyceride lipase, diacylglyceride lipase, and phosphatidylcholine lipase secreted by fed females in the caecum and ventriculus is 1:1.4:0.4. These activities decrease in the caecum by 30–40% in unfed females. The total lipase activity (TLA) in the caecum is about 10 times that in the ventriculus. Minimal lipase secretion occurs before and during the final moult, and remains at this level in unfed crickets, indicating a basal secretion rate. In 2‐day‐old fed females, about 10% of the TLA in the entire gut is found in the crop, about 70% in the caecum, 20% in the ventriculus, and 3% in the ileum. Lipases in the ventriculus are recycled back to the caecum and little is lost in the feces. Oleic acid stimulated in vitro lipase secretion, but lipids did not. Feeding stimulated lipase secretion, starvation reduced lipase secretion, but this does not prove a direct prandal regulation of secretion, because feeding also induced a size and volume increase of the caecum.
Randomized clinical trial of perioperative nerve block and continuous local anaesthetic infiltration via wound catheter versus epidural analgesia in open liver resection (LIVER 2 trial)
Authors: Hughes M J , Harrison E M , Peel N J , Stutchfield B , McNally S , Beattie C , Wigmore S J
Published: October 2015

Background

Analgesia after liver surgery remains controversial. A previous randomized trial of continuous wound infiltration (CWI) versus thoracic epidural analgesia (TEA) after liver surgery (LIVER trial) showed a faster recovery time in the wound infiltration group but better early postoperative pain scores in the TEA group. High-level evidence is, however, limited and opinion remains divided. The aim was to determine whether there is a difference in functional recovery time between patients having CWI plus abdominal nerve blocks versus TEA after liver resection.

Methods

A randomized unblinded clinical trial of patients undergoing open liver resection was commenced in December 2012, with follow-up to August 2014. Patients were randomized to receive either wound catheter and nerve block (CWI group) or TEA for 48 h after surgery. The primary outcome measure was functional recovery time. Secondary outcomes were pain scores, complication rates, inflammatory response and central venous pressure (CVP) during transection.

Results

Of 50 patients randomized initially to each group, 44 received TEA and 49 CWI. Median (i.q.r.) recovery time was 6·5 (5–9·75) and 5·75 (4–7) days in the TEA and CWI groups respectively (P = 0·036). Pain scores were not significantly different between the two groups, and there were no differences in morbidity, inflammatory response or CVP during transection.

Conclusion

Wound infiltration is associated with a reduced time to recovery after open liver resection compared with epidural analgesia. TEA does not offer an advantage over CWI in terms of attenuation of the inflammatory response or pain scores. Registration number: NCT01747122 (http://www.clinicaltrials.gov).
Interventional ductoscopy in patients with pathological nipple discharge
Authors: Waaijer L , van Diest P J , Verkooijen H M , Dijkstra N -E , van der Pol C C , Borel Rinkes I H M , Witkamp A J
Published: October 2015

Background

Surgery is the intervention of choice for definitive diagnosis and treatment in women with pathological nipple discharge (PND). Ductoscopy has been reported to improve diagnosis, but as an interventional procedure it may also reduce the need for surgery. This study evaluated interventional ductoscopy in patients with PND.

Methods

A prospective study on ductoscopy was conducted in consecutive patients with PND, but without a suspected malignancy on routine diagnostic evaluation. Intraductal lesions were removed by ductoscopic extraction. Surgery was undertaken if there were suspicious ductoscopic findings or at the patient's request. Therapeutic efficacy was determined by cannulation success, detection and removal rates, symptom resolution and avoided surgery.

Results

Ductoscope introduction was successful in 71 (87 per cent) of 82 patients, with abnormalities visualized in 53 (65 per cent); these were mostly polypoid lesions (29 patients). The lesion was removed in 27 of 34 attempted ductoscopic extractions. Twenty-six (32 per cent) of the 82 patients underwent surgery, whereas surgery was avoided in 56 (68 per cent). After a median follow-up of 17 (range 3–45) months, 40 patients (49 per cent) no longer experienced symptoms of PND, 13 of 34 patients experienced an insufficient therapeutic effect after attempted ductoscopic extraction, and the outcome was unknown in two (2 per cent). Malignancy was diagnosed in four patients (5 per cent); two had been missed at ductoscopy and two at initial surgery after ductoscopy.

Conclusion

Interventional ductoscopy is technically feasible and may help to avoid surgery in the majority of patients. As endoscopic removal of intraductal lesions is not always possible and malignancy can be the underlying cause of PND, ductoscopic instruments should be further optimized to allow definitive histological diagnosis.

Published: October 2015

Cyclo‐oligo‐(1→6)‐β‐D‐glucosamines functionalized with hydrophobic tails are reported as a new class of transmembrane ion‐transport system. These macrocycles with hydrophilic cavities were introduced as an alternative to cyclodextrins, which are supramolecular systems with hydrophobic cavities. The transport activities of these glycoconjugates were manipulated by altering the oligomericity of the macrocycles, as well as the length and number of attached tails. Hydrophobic tails of 3 different sizes were synthesized and coupled with each glucosamine scaffold through the amide linkage to obtain 18 derivatives. The ion‐transport activity increased from di‐ to tetrameric glucosamine macrocycles, but decreased further when flexible pentameric glucosamine was introduced. The ion‐transport activity also increased with increasing length of attached linkers. For a fixed length of linkers, the transport activity decreased when the number of such tails was reduced. All glycoconjugates displayed a uniform anion‐selectivity sequence: Cl−>Br−>I−. From theoretical studies, hydrogen bonding between the macrocycle backbone and the anion bridged through water molecules was observed.

Investigation of the Aggregation Properties of a Chiral Porphyrin Bearing Citronellal Meso Substituent Groups
Authors: Castriciano Maria Angela , Zagami Roberto , Trapani Mariachiara , Romeo Andrea , Patanè Salvatore , Monsù Scolaro Luigi
Published: October 2015

A new porphyrin bearing four R or S hydrogenated citronellal units directly bound to the meso positions of the porphyrin ring was synthesized and fully characterized through MALDI‐TOF, NMR, UV/Vis absorption, and fluorescence emission spectroscopies. Both enantiomers exhibit a monomeric nature in a series of organic solvents. Acting on the polarity of the solvent, i.e., increasing the amount of water in mixture with acetone, aggregation occurs, as revealed by UV/Vis absorption, fluorescence emission, and resonance light scattering. The occurrence of both H‐ and J‐type aggregates was suggested by fluorescence lifetime measurements. In contrast to the monomeric species, these aggregates exhibit CD spectra reflecting the chirality of the building blocks. AFM microscopy shows that micrometer ribbon‐like structures form by the casting solution of these porphyrins in acetone/water onto a glass surface.

State of the Art in Steel Mill Dust Recycling
Authors: Antrekowitsch Jürgen , Rösler Gernot , Steinacker Stephan
Published: October 2015

The Waelz technology still represents the main process for treating electric arc furnace dust (EAFD). Interesting developments within this process and some new approaches transform the product into a competitor for the primary metallurgical industry by producing high grade zinc from the Waelz oxide. Another progress constitutes the utilization of the slag, which turns the Waelz technology into a zero‐waste process. An outlook regarding the future role of low zinc‐containing EAFD from basic oxygen furnaces and an overview concerning the world‐wide generation of EAFD and possible future solutions are described as well.
