Garment fit and still air between clothing layers affect heat transfer through the clothing and thus the thermal insulation. Wind and body movement decreases clothing insulation by causing ventilation inside the clothing and by compressing air layers. The objective was to find the optimum size combination of three-lay…
Restoration of sp 2 hybridization in a GO framework by the transfer of photo-excited electrons from CHL-a to GO resulted in the formation of a RGO/CHL-a nano hybrid, an efficient electron transfer catalyst for next generation bio-fuel cells.
Improved PCE (from 2.5 to 3.2%) and stability of SubPc/C 60 -based OPV device using an UV-ozone treated ZnO anode buffer.
A new facile method allows the manipulation of plasmon coupling in 2D assemblies of gold nanoparticles with a precision of nanometers.
The detection of trace amounts (<10 ppb) of heavy metals in aqueous solutions is described using 1,3,5-hexahydro-1,3,5-triazines (HTs) as chemical indicators and a low cost fluorimeter-based detection system. This method takes advantage of the inherent properties of HTs to coordinate strongly with metal ions in soluti…
Tetra-imidazole-appended p-phenylene-Cu(ii) doped nanofibrous membranes (IP-Cu-NMs) as portable chemoprobes were prepared using the electrospinning method. Fluorescence changes were observed upon dropping amino acids and proteins containing histidine residues onto the surface. IP-Cu-NMs prepared with 1.0 equivalent of…
We have synthesized three Metal-Organic Frameworks (MOFs) in which Zn metal ions form the secondary building unit, and 4,4'-sulfonyldibenzoic acid (SDB) serves as the ligand: [[Zn(DMF)(SDB)](DMF), 1, [Zn(3)(DMF)(3)(SDB)(3)](DMF), 2 and [Zn(3)(OH)(2)(SDB)(2)] (DMF)(2), 3, where DMF = dimethyl formamide]. Compound conta…
Sannakaisa Virtanen opened a general discussion of the paper by Mira Todorova: In view of the fact that there is a lot of data available for ZnO (as a semiconducting oxide), how “easy or difficult” is it to use the same methodology for other oxides, such as for instance iron oxides or chromium
We demonstrate that layered carbon black nanoparticles can be oxidatively peeled via the reaction with potassium permanganate in sulfuric acid.
In order to expand the application of bio-derived polymers it is imperative that the issues related to their poor gas barrier properties be addressed.
For the first time, the effects of iron-subgroup metal chlorides on polymer cord conversion to liquid and gaseous pyrolysis products have been studied.
Abstract—Here we present the design of a low loss top metal silicon (Si) hybrid dielectric-loaded plasmonic waveguide (TM-SiHDLW) and a compact, high performance optical resonator by numerical simulation based on finite element method. The waveguide adopted a thick (200 nm) top metal stripe structure to yield optimal…
ZnO nanoplates assembled by rod-like nanoparticles were synthesized by a simple reflux route without assistance of any additive or template.
The possibilities to employ phenol and oxime functionalities as fluoride recognition motif are investigated. The recognition involves H-bonding followed by deprotonation.
Novel 3D air-cathodes were constructed using stainless steel felt as the diffusion backing and current collector for performance improvement of MFC.
We discuss the results of an investigation into the structure/property correlations of γ-substituted poly( N -acryloyl-2-pyrrolidone)s, a recently reported class of pyrrolidone-based polymers prepared from pyroglutamic acid, a bio-derived resource.
We synthesized mesoporous hollow carbon on a graphene surface (MHCG). When applied into supercapacitor electrode, MHCG electrode exhibited outstanding maintenance of energy density above 30 W h kg −1 even under 1 kW kg −1 power density.
We present a study on the photoluminescence (PL) of thin films of poly-(p-phenylene vinylene) (PPV), non-stretched and uniaxially stretched. The experimental study was carried out using linear polarized light as the excitation beam, oriented either parallel or perpendicular to the stretch axis (S). The results showed…
Multicarboxy (8, 16) functionalized cage silsesquioxanes were synthesized through the photochemical thiol-ene reaction of octavinylsilsesquioxane with 3-mercaptopropionic acid and mercaptosuccinic acid, respectively. These two cage precursors acted as ligands to coordinate with terbium ion (Tb3+) to obtain two novel h…
The protein crystals grown using the cross-diffusion microbatch method exhibited better quality than those grown using the sitting-drop vapor diffusion method.
