Highly conductive, flexible, and transparent electrodes (FTEs) of PEDOT: PSS films on plastic substrates have been achieved using strong acid treatments. However, it is rare to realize a performance attenuation of PEDOT: PSS FTEs on plastic substrates and flexible optoelectronic devices because of strong acid residues…
Graphene and its derivatives hold a great promise for widespread applications such as field-effect transistors, photovoltaic devices, supercapacitors, and sensors due to excellent properties as well as its atomically thin, transparent, and flexible structure. In order to realize the practical applications, graphene ne…
The aim of this study was to produce a novel microcrystalline cellulose (MCC) reinforced polylactic acid (PLA), fully degradable biocomposites for 3D printing applications. The biocomposites were produced in filament form by solvent casting and twin screw extrusion to achieve final concentrations of 1, 3, and 5 wt% of…
Transition-metal dichalcogenide (TMD) nanolayers show potential as high-performance catalysts in energy conversion and storage devices. Synthetic TMDs produced by chemical-vapor deposition (CVD) methods tend to grow parallel to the growth substrate. Here, we show that with the right precursors and appropriate tuning o…
This review highlights and summarizes various optically active porphyrin and phthalocyanine molecules prepared using a wide range of structural modification methods to improve the design of novel structures and their applications. The induced chirality of some illustrative achiral bis-porphyrins with a chiral guest mo…
The objective of this paper is to emphasize the fact that while consistent interest has been paid to the industrial use of chitosan, minor attention has been devoted to spread the knowledge of a good characterization of its physico-chemical properties. Therefore, the paper attempts to critically comment on the conflic…
Kilometer-scale continuous graphene fibers (GFs) with outstanding mechanical properties and excellent electrical conductivity are produced by high-throughput wet-spinning of graphene oxide liquid crystals followed by graphitization through a full-scale synergetic defect-engineering strategy. GFs with superior performa…
Previously, catalytic cerium oxide nanoparticles (CNPs, nanoceria, CeO2-x NPs) have been widely utilized for chemical mechanical planarization in the semiconductor industry and for reducing harmful emissions and improving fuel combustion efficiency in the automobile industry. Researchers are now harnessing the catalyt…
A Sn-doped (100)$\beta $-Ga2O3epitaxial layer was grown via metal–organic vapor phase epitaxy onto a single-crystal, Mg-doped semi-insulating (100)$\beta $-Ga2O3substrate. Ga2O3-based metal–oxide–semiconductor field-effect transistors with a 2-$\mu \text{m}$gate length ($L_{G})$, 3.4-$\mu \text{m}$source–drain spacing…
Abstract Evolution of the bioplastics industry has changed directions dramatically since the early 1990s. The latest generation is moving toward durable bioplastics having high biobased content. The main objective is to replace ?fossil carbon? with ?renewable carbon?, a holistic strategy to mitigate climate change by…
Στην παρούσα διπλωματική εργασία μελετάμε την ηλεκτρική και θερμική συμπεριφορά δύο υπόγειων trefoil διατάξεων καλωδίων, που χρησιμοποιούνται για τη μεταφορά ηλεκτρικής ενέργειας εναλλασσόμενου ρεύματος, καθώς και το μαγνητικό πεδίο που αναπτύσσεται στο γειτονικό περιβάλλον. Για την καλύτερη προσομοίωση του μοντέλου η…
Este trabalho, realizado junto ao Grupo de Novos Materiais e Dispositivos (GNMD) pertencente ao Laboratório de Microeletrônica (LME) da Universidade de São Paulo, teve como objetivo correlacionar algumas propriedades físico-químicas de filmes finos de Ba1-XSrxTiO3 (BST), obtidos pela técnica de pulverização catódica r…
This paper presents research results of phosphate removal from aqueous solution using ZnCl2–loaded chitosan adsorbent. The adsorption results of the ZnCl2/chitosan compo-site were compared to those of ZnO/chitosan and nano-ZnO/chitosan composites. Adsorbent was characterised by Fourier Transform Infrared Spectral stud…
Väestönkasvu ja teollistumien lisäävät kulutushyödykkeiden kysyntää merkittävästi lä-hitulevaisuudessa. Muutokset heijastuvat myös tekstiilikuitujen kulutukseen ja niiden ekologisille valmistustavoille on kasvava kysyntä. Aalto-yliopiston Kemian tekniikan korkeakoulu ja Helsingin yliopisto ovat kehittäneet uuden Ionce…
The interests towards using plastics as a piping material has been continuously increasing in the shipping industry, especially because of a better corrosion resistance compared to the conventional metal materials. This change has brought fort major concerns among the ship owners and administrations about the fire saf…
Li-rich layered oxides have attracted attention as promising positive electrode materials for next-generation lithium-ion secondary batteries because of their high energy storage capacity. The participation of the oxygen anion has been hypothesized to contribute to these oxides' high capacity. In the present study, we…

The potentials of Aro-Ndizuogu clay as an extender in gloss paint have been investigated. The physical properties of the local clay investigated: refractive index (1.54), pH (7.10), oil absorption (32g/100g clay), and specific gravity (2.13) compared favourably with that of conventional extenders. Gloss paints were pr…
