Conclusions and outlook. 330 $aThis book highlights the origin of low external quantum efficiency for deep ultraviolet light-emitting diodes (DUV LEDs). In addition, it puts forward solutions for increasing the internal quantum efficiency and the light extraction efficiency of DUV LEDs. The book chiefly concentrates on approaches that can be used to improve the crystalline quality, increase carrier injection, reduce the polarization-induced electric field within multiple quantum wells, suppress the TM polarization emission, and enhance the light escape from the semiconductor layer. It also demonstrates insightful device physics for DUV LEDs, which will greatly benefit the optoelectronic community. 410 0$aNanoscience and Nanotechnology,$x2196-1670 606 $aOptical materials 606 $aMicrowaves 606 $aOptical and Electronic Materials$3http://scigraph.springernature.com/things/product-market-codes/Z12000 606 $aMicrowaves, RF and Optical Engineering$3http://scigraph.springernature.com/things/product-market-codes/T24019 606 $aOptics, Lasers, Photonics, Optical Devices$3http://scigraph.springernature.com/things/product-market-codes/P31030 606 $aSignal, Image and Speech Processing$3http://scigraph.springernature.com/things/product-market-codes/T24051 615 0$aOptical materials. 615 0$aMicrowaves. 615 14$aOptical and Electronic Materials. 615 24$aMicrowaves, RF and Optical Engineering. 615 24$aOptics, Lasers, Photonics, Optical Devices. 615 24$aSignal, Image and Speech Processing. 676 $a620.11295 676 $a620.11297 700 $aZhang$b Zi-Hui$4aut$4http://id.loc.gov/vocabulary/relators/aut$0875253 702 $aChu$b Chunshuang$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aTian$b Kangkai$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aZhang$b Yonghui$4aut$4http://id.loc.gov/vocabulary/relators/aut 906 $aBOOK 912 $a9910350303903321 996 $aDeep Ultraviolet LEDs$91954057 997 $aUNINA LEADER 04566nam 2201081z- 450 001 9910557606803321 005 20220111 035 $a(CKB)5400000000045334 035 $a(oapen)https://directory.doabooks.org/handle/20.500.12854/76643 035 $a(oapen)doab76643 035 $a(EXLCZ)995400000000045334 100 $a20202201d2021 |y 0 101 0 $aeng 135 $aurmn|---annan 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aGraphene-Polymer Composites II 210 $aBasel, Switzerland$cMDPI - Multidisciplinary Digital Publishing Institute$d2021 215 $a1 online resource (115 p.) 311 08$a3-0365-1678-6 311 08$a3-0365-1677-8 330 $aGraphene-polymer nanocomposites continue to gain interest in diverse scientific and technological fields. Graphene-based nanomaterials present the advantages of other carbon nanofillers, like electrical and thermal conductivity, while having significantly lower production costs when compared to materials such as carbon nanotubes, for instance. In addition, in the oxidized forms of graphene, the large specific area combined with a large quantity of functionalizable chemical groups available for physical or chemical interaction with polymers, allow for good dispersion and tunable binding with the surrounding matrix. Other features are noteworthy in graphene-based nanomaterials, like their generally good biocompatibility and the ability to absorb near-infrared radiation, allowing for the use in biomedical applications, such as drug delivery and photothermal therapy.This Special Issue provides an encompassing view on the state of the art of graphene-polymer composites, showing how current research is dealing with new and exciting challenges. The published papers cover topics ranging from novel production methods and insights on mechanisms of mechanical reinforcement of composites, to applications as diverse as automotive and aeronautics, cancer treatment, anticorrosive coatings, thermally conductive fabrics and foams, and oil-adsorbent aerogels. 606 $aTechnology: general issues$2bicssc 610 $aadhesives 610 $abiobased polymer nanocomposites 610 $acellulose nanocrystal 610 $acellulose nanofibers 610 $acohesive zone model 610 $acomposite fiber 610 $aconducting polymer 610 $acorrosion 610 $acrystallization 610 $acytotoxicity 610 $adirectional freeze-drying 610 $aDNA damage 610 $aelastic recovery 610 $aelectrical conductivity 610 $aelectrospinning 610 $aelongational flow 610 $afabric 610 $afinite element method 610 $agraphene 610 $agraphene nanoplatelets 610 $agraphene oxide 610 $agraphene oxide-platinum nanoparticles nanocomposites 610 $agraphene polymer matrix composite 610 $agraphene-polymer nanocomposite 610 $agraphene/polymer interface 610 $aHalpin-Tsai 610 $ahydrogen bond 610 $ain situ melt polycondensation 610 $ainterfacial bonding 610 $aLEIS 610 $alight emitting diode 610 $amechanical property 610 $amitochondrial membrane potential 610 $amolecular dynamics 610 $amorphology 610 $an/a 610 $aoil absorption 610 $aoxidative stress 610 $aPANI 610 $aphototherapy 610 $apoly(trimethylene terephthalate) 610 $apolyamide 66 610 $apolyethylene glycol 610 $apolymer composite fiber 610 $apolypropylene 610 $apolysulfone foams 610 $apolyvinyl alcohol 610 $aprostate cancer 610 $arecycled rubber 610 $aregressive softening law 610 $ascCO2 610 $aSEM 610 $athermal conductivity 610 $athermal reduction 610 $athermal stability 610 $atortuosity 610 $atoughening mechanisms 610 $atung oil 610 $aunsaturated polyester resins 610 $awater vapor induced phase separation 615 7$aTechnology: general issues 700 $aPinto$b Artur$4edt$01332363 702 $aMagalha?es$b Ferna?o D$4edt 702 $aPinto$b Artur$4oth 702 $aMagalha?es$b Ferna?o D$4oth 906 $aBOOK 912 $a9910557606803321 996 $aGraphene-Polymer Composites II$93040890 997 $aUNINA
