Yet, they are also the most controversial because of the possibility of extrinsic effects attributable to dopant solubility and clustering, point defects, incorporation of unintentional impurities, etc. This has highlighted the central role of materials chemistry in rendering a specific microstate and property response. In this work, we provide a combined window of high-resolution scanning transmission electron microscopy and electron energy-loss spectrometry, X-ray absorption (XAS)/X-ray magnetic circular dichroism (XMCD), and magnetization measurements on epitaxial rutile CoxTi1-xO2 (x = 0-0.06) system (the first discovered oxide-DMS, which continues to be controversial) grown at low temperature (400 degrees C) under different ambient atmospheres. The study brings out a mixed-state scenario of ferromagnetism involving intrinsic DMS (uniform dopant distribution at low dopant concentration) and coupled cluster magnetism, involving cobalt associations within the matrix at higher concentrations. We also show that by matrix valence control during growth, it is possible to realize a uniform embedded cluster state and the related coupled cluster magnetism.</p>1 aOgale, Satishchandra, B.1 aKundaliya, Darshan1 aMehraeen, Shareghe1 aFu, Lian-feng1 aZhang, Shixiong1 aLussier, Alexandre1 aDvorak, Joe1 aBrowning, Nigel, D.1 aIdzerda, Yves1 aVenkatesan, Thirumalai  uhttps://library.ncl.res.in/content/chemical-inhomogeneity-and-mixed-state-ferromagnetism-diluted-magnetic-semiconductor-co-002727nas a2200253   4500008004100000022001400041245013800055210006900193260007100262300001200333490000700345520177100352100002502123700001902148700002202167700002602189700001802215700001902233700002402252700002302276700001802299700002902317856012702346       2008                        eng d  a0897-475600aCo : CdS diluted magnetic semiconductor nanoparticles: radiation synthesis, dopant-defect complex formation, and unexpected magnetism0 aCo CdS diluted magnetic semiconductor nanoparticles radiation sy  a1155 16TH ST, NW, WASHINGTON, DC 20036 USAbAMER CHEMICAL SOCcJAN  a440-4460 v203 a<p>Incorporating a dopant into a nanoparticle is a nontrivial proposition in view of the size dependent surface versus bulk energy considerations and the intrinsic proximity of the surface to the interior, which facilitates migration to the surface. If realized and controlled, however, it can open up new avenues to novel nanomaterials. Some previous studies have shown the dopability of nanosystems but only with specific surface functionalization. Here, we demonstrate the successful dopant incorporation via a new route of pulsed high energy electron induced synthesis. We choose a system Co:CdS (dilutely cobalt doped cadmium sulfide) in view of the well-known application-worthy properties of CdS and the potential possibility of its conversion to a diluted magnetic semiconductor of interest to spintronics. By using various techniques, we show that matrix incorporation and uniform distribution of cobalt are realized in US nanocrystals without the need for additional chemical or physical manipulation. Optical and photoluminescence properties also support dopant incorporation. Interestingly, although magnetism is realized, it is weak, and it decreases at higher cobalt concentration. First principle density functional calculations are performed to understand this counterintuitive behavior. These calculations suggest that the introduction of parent cation or anion vacancies lead to magnetic moment reduction, albeit marginally. However, with some Co impurity fraction in the octahedral interstitial site inside the wurtzite cage, the magnetic moment drops down drastically. This study reveals that defect states may have an interesting role in dopant stabilization in nanosystems, with interesting system dependent consequences for the properties.</p>1 aBogle, Kashinath, A.1 aGhosh, Saurabh1 aDhole, Sanjay, D.1 aBhoraskar, Vasant, N.1 aFu, Lian-feng1 aChi, Miao-Fang1 aBrowning, Nigel, D.1 aKundaliya, Darshan1 aDas, Gour, P.1 aOgale, Satishchandra, B.  uhttps://library.ncl.res.in/content/co-cds-diluted-magnetic-semiconductor-nanoparticles-radiation-synthesis-dopant-defect-001532nas a2200253   4500008004100000022001400041245012400055210006900179260007900248300001200327490000700339520059300346653002900939653002300968653001700991653001601008653002501024100001601049700001701065700002001082700002901102700001901131856012801150       2009                        eng d  a1388-248100aChemical bath deposition of CdS quantum dots on vertically aligned ZnO nanorods for quantum dots-sensitized solar cells0 aChemical bath deposition of CdS quantum dots on vertically align  a360 PARK AVE SOUTH, NEW YORK, NY 10010-1710 USAbELSEVIER SCIENCE INCcJAN  a103-1060 v113 a<p>Formation of US quantum dots (Q dots) on the vertically aligned ZnO nanorods electrode was carried out by chemical bath deposition.

MPA conjugates with NCO forming a metal-carboxylate linkage, with the MPA-MPA interaction occurring via formation of disulfide bonds, leaving another carboxyl end free for additional conjugation. The cytotoxicity studies on NCO-MPA show cell viability of similar to 100% up to a dosage of 40 mu g/mL on SiHa, MCF7, and B16F10 cell lines, and on mouse primary fibroblasts. Time-dependent cell viability studies done for a duration of 72 hours showed the cell lines' viability up to 80% for dosages as high as 80 mu g/mL. Negligible leaching (&lt;5 ppm) of ionic Co or Ni was noted into the delivery medium. Upon subjecting the NCO-MPA dispersion (0.1 mg/mL) to radiofrequency absorption, the nanoparticles were heated to 75 degrees C within 2 minutes, suggesting its promise as a magnetic hyperthermia agent. Furthermore, the amino acid lysine and the drug cephalexin were successfully adducted to the NCO system, suggesting its potential for drug delivery.

Because portable power source is an essential need of such wearable devices, currently there is considerable research emphasis on the development of planar interdigitated micro energy-torage devices by employing diverse precursor materials to obtain functional materials (functional carbon, oxides, etc.) with the desirable set of properties. Herein we report for the first time the use of metal organic framework (MOF) and zeolitic imidazolate framework (ZIF-67) for high-wavelength photothermal laser direct writing of metal-decorated, heteroatom-doped, porous few-layer graphene electrodes for microsupercapacitor application. We argue that the specific attributes of MOF as a precursor and the high-wavelength laser writing approach (which creates extremely high localized and transient temperature (>2500 degrees C) due to strong absorption by lattice vibrations) are together responsible for the peculiar interesting properties of the carbon material thus synthesized, thereby rendering extremely high cycling stability to the corresponding microsupercapacitor device. Our device exhibits near 100% retention after 200 000 cycles as well as stability under 150 degrees bending.1 aBasu, Aniruddha1 aRoy, Kingshuk1 aSharma, Neha1 aNandi, Shyamapada1 aVaidhyanathan, Ramanathan1 aRane, Sunit1 aRode, Chandrashekhar, V.1 aOgale, Satishchandra, B.  uhttps://library.ncl.res.in/content/co2-laser-direct-written-mof-based-metal-decorated-and-heteroatom-doped-porous-graphene
