Bismuth telluride-based thermoelectric (TE) materials are historically recognized as the best p-type (ZT = 1.8) TE at room temperature. However, poor performance of n-type (ZT≈1.0) counterparts seriously reduces efficiency device. Such imbalance severely impedes its applications either in electrical generation or refrigeration. Here, a strategy to boost Bi
To elucidate low-dimensional effects on thermoelectric materials, bismuth telluride film and nanowires array were fabricated by potentiostatically electrodeposition. Both materials are slightly Te-rich, n-type Bi2Te3, exhibiting preferred orientation in rhombohedral strcture. For both the Seebeck coefficient S ≈ −70 μV/K at 300 K decreases linearly with decreasing temperature, showing a diffusive nature of current flow. The temperature dependence resistivity (=1/σ) obtained from data...
The strategy for shape control of alloy FePt nanocrystal was studied systematically. By the careful adjustments reaction parameters in a solution reaction, surfactant−facet bindings on growth seed were controlled delicately. octapod, cuboctahedron, truncated cube, and nanocube successfully prepared from cuboctahedral examined by high-resolution transmission electron microscopy. formations nanostructures mainly attributed to differences rate between {111} {100} planes seeds. magnetic...
Low-cost and large-area electronic applications require the deposition of active materials in simple inexpensive techniques at room temperature; properties usually associated with polymer films. In this study, we demonstrate a simple, low-cost environmentally friendly method for high-yield production two dimensional nanosheets semiconducting transition metal disulfides, integrated route towards solution-processed MoS2 WS2 thin The resulting high purity no contamination or distortion their...
A new multiferroic material, CuBr2, is reported for the first time. CuBr2 has not only a high transition temperature (close to liquid nitrogen temperature) but also low dielectric loss and strong magnetoelectric coupling. These findings reveal importance of anion effects, in search multiferroics materials among these low-dimensional spin systems.
Narrow-band green-emitting phosphor β-SiAlON:Eu has been widely used in advanced wide-gamut backlighting devices. However, the origins for unusual sharp lines photoluminescence emission at room temperature and tunable narrow-band-emission tailored by reducing Al–O are still unclear. Here, presence of sharp-line fine structure spectra is mainly due to purely electronic transitions (zero phonon lines), their vibronic repetitions resulting from multimicroenvironment around Eu2+ ions that...
A record high zT of 2.2 at 740 K is reported in Ge0.92Sb0.08Te single crystals, with an optimal hole carrier concentration ≈4 × 1020 cm-3 that simultaneously maximizes the power factor (PF) ≈56 µW cm-1 K-2 and minimizes thermal conductivity ≈1.9 Wm-1 K-1. In addition to presence herringbone domains stacking faults, exhibits significant modification phonon dispersion extra excitation around ≈5-6 meV Γ point Brillouin zone as confirmed through inelastic neutron scattering (INS) measurements....
Abstract Background: Adult intussusception is a rare clinical entity. The presentations and optimal management of adult in Asians have seldom been reported. purpose this study was to determine the causes Taiwan. Methods: A retrospective review performed at four medical centers Taiwan identified 46 patients, least 18 years old, with diagnosis intestinal from January 1992 December 2005. Data related presentations, diagnosis, treatment, pathology were analyzed. Results: There 28 men women mean...
Demethoxycurcumin (DMC), curcumin (Cur), and bisdemethoxycurcumin (BDMC) are major forms of curcuminoids found in the rhizomes turmeric. This study examined effects three curcuminoid analogues on breast cancer cells. The results revealed that DMC demonstrated most potent cytotoxic MDA-MB-231 Compared with estrogen receptor (ER)-positive or HER2-overexpressing cells, efficient triple-negative (TNBC) However, nonmalignant MCF-10A cells were unaffected by treatment. showed activated AMPK TNBC...

Abstract Intrahepatic bile duct (IHBD) dilatations are a rare disease and can lead to the formation of intrahepatic stones, cholangitis, even cholangiocarcinoma. Surgical resection affected segments has traditionally been considered only effective approach in symptomatic patients. Here, we present successful chemical ablation IHBD using ethanol through percutaneous transhepatic cholangial drainage an 82-year-old patient who is at high risk for surgery.
In this investigation, detection dogs are trained and used in identifying red imported fire ants, Solenopsis invicta Buren, their nests. The methodology could assist reducing the frequency scope of chemical treatments for ant management thus reduce labor costs use as well improve control quarantine efficiency. Three previously customs were retrained to detect scents ants. After passing tests involving different numbers live ants three other species--Crematogaster rogenhoferi Mayr,...

We hypothesized that sorafenib plus transarterial chemoembolization (TACE) would confer survival benefits over alone for advanced hepatocellular carcinoma (aHCC). investigated this while using the population-based All-Cancer Dataset to assemble a cohort (n = 3674; median age, 60; 83% men) of patients receiving aHCC (Child-Pugh A) with macro-vascular invasion or nodal/distant metastases. The were classified into sorafenib-TACE group 426) propensity score-matched sorafenib-alone 1686). All...
In recent years, ultrasound attenuation imaging (ATI) has emerged as a new method to detect liver steatosis. However, thus far, no studies have confirmed the clinical utility of this technology. Using retrospective database analysis 28 patients with chronic disease who underwent biopsy and ATI, we compared presence degree steatosis measured by ATI results obtained through biopsy. The area under receiver operating characteristic curve (AUROC) for differentiating between normal hepatic was...
