Abstract:
A simple and novel transparency sheet-based colorimetric detection device using gold nanoparticles (AuNPs) modified by 4-Amino-6-hydroxy-2-mercaptopyrimidine monohydrate (AHMP) was fabricated and developed for the determination of calcium ions (Ca2+). The detection was based on a colorimetric reaction as a result of the aggregation of modified AuNPs induced by Ca2+ due to the ability to form strong electrostatic interactions between positively charged Ca2+ and negatively charged modified AuNPs. Probe solution changes color from red to blue in the presence of Ca2+ and can be observed by the nak

Abstract:
Novel methods have been developed to measure the fractional deposition efficiency for nanoparticles of full-scale HVAC and HEPA filter cassettes down to a particle size of 3.5 nm. The methods use a flame spray nanoparticle generator to produce NaCl test aerosols with narrow size distributions and very high concentrations. While the efficiency curves of lower efficiency filters of classes F7 and E10 were still able to be determined by measuring the size distributions of the polydisperse test aerosols upstream and downstream of the filter, two new testing procedures were developed for high effic

Abstract:
In this study, adhesion improved silver nanowires (AgNWs) conducting film was produced via the meniscus dragging deposition method. In order to improve adhesion of AgNWs films, the AgNWs were surface-modified with (3-aminopropyl)triethoxysilane (APTES) and coated over the pristine AgNWs networked film. Based on this strategy, the positively charged amine groups of the APTES-AgNWs and the negatively charged hydroxyl groups of the substrates formed electrostatic bonds, improving the adhesion between the AgNWs and substrates without sacrificing conductivity.

Abstract Composite sheets consisting of elongated and aggregated cationically charged precipitated calcium carbonate (PCC) and native microfibrillated cellulose (MFC) were prepared with a wet laying method. The furnishes were prepared with and without an anionic flocculating agent (polyacrylamide) in order to adjust the structure of the sheet. The samples were compressed (densified) in order to determine the particle and microfibrillated cellulose-PCC structure coalescence and densification, as well as its subsequent influence on liquid absorption behavior. The densification affected both the

Abstract:
We demonstrate a method for the formation of multilayers composed of reduced graphene oxide (rGO), which can be used for transparent, conducting thin films. Using the layer-by-layer (LbL) assembly of positively and negatively charged GO sheets, we could obtain thin films with highly controllable sheet resistance. The natural negative charge of graphene oxide was turned to positive by the amidation reaction. After forming the multilayer films, the graphene oxide underwent thermal reduction at temperatures above 150 °C. The (rGO+/rGO−) films were characterized by UV-Vis and scanning electron mic

Abstract:
Conventional or non-conventional chemical threat is gaining huge attention due to its unpredictable and mass destructive effects. Typical military protective suits have drawbacks such as high weight, bulky structure, and unpredictable lifetime. A durable, light, and scalable graphene e-fabric was fabricated from CVD-grown graphene by a simple co-lamination method. The sheet resistance was below 1 kΩ/sq over the wide surface area even after 1000 bending cycles. A graphene triboelectric nanogenerator showed the peak VOC of 68 V and the peak ICC of 14.4 μA and 1 μF capacitor was charged successfu

Abstract:
The characterization of membranes is suitable to investigate changes in the membrane properties caused by Layer-by-Layer (LbL) modification. Besides permeability, rejection, and molecular-weight cut-off (MWCO), which give information about the modification of the separation behaviour of the membrane, the zeta potential is capable of describing the surface charge of the membrane and its variation impacted by the properties of the polyelectrolyte multilayers (PEM). In this study, a new method for zeta potential measurement of hollow fibre membranes with several capillaries was developed and furt

Abstract:
The outer membrane of Gram-negative bacteria, such as E. coli, contains a high density of a family of pore-forming proteins, which are often called porins. One member of the family, PhoE porin, is expressed under conditions of phosphate starvation, and has been shown to favor the transport of phosphate-containing compounds and negatively charged molecules. The three-dimensional (3-D) structure of PhoE porin obtained from two-dimensional crystals, negatively stained with uranyl acetate, has been determined to a resolution of about 18Å.

"Sales and other revenues 9. Profit and loss accounts and results of operations In fact, there were two charts of accounts: a complete one with ten classes for companies which used cost accounting, and a simplified one without the cost accounting classes (numbers 5, 6 and 7) for others. Due to the integration of cost accounting into the accounting chart, there had to be two formats for the trading account and two for the profit and loss account: one set of state­ ments classifying expenses by destination (functions) for compa­ nies using the cost accounting classes, and another classifying ex­ penses by nature for companies which did not use these classes. The 1942 French Plan was developed on the basis of a docu­ ment prepared by Chezlepretre, a Vichy government senior civil servant within the Ministere de I’lzconomie Nationale et des Fi­ nances, who had been trained as a statistician [Standish, 1990, p. 346]. Chezlepretre had probably drawn up his Plan using the 1937 Goering Plan as a starting point since it had the only official chart of accounts in use at the time. In fact, there are similarities be­ tween the German and the 1942 French charts. In both the German and French charts, cost accounting was integrated with financial accounting. This arrangement of ac­ counts reflected Schmalenbach's conception, in which the chart of accounts follows the cycle of manufacturing activity: first, capital is raised and invested in fixed and current assets; then, materials are purchased and processed to create products that are sold; and lastly, all accounting elements are assembled in class 9 for the periodic closing of the books. However, even if the German and the 1942 French charts of accounts were similar, the French influence had impact in two areas of the 1942 Plan: product costing and the standard balance sheet. The resulting characteristics were later retained in the 1947 Plan. First the latest innovations in French cost accounting were embodied in the 1942 Plan. The homogeneous sections method, developed and defined by Lieutenant-Colonel Rimailho in a 1928 pamphlet under the aegis of the Commission Generale d'Organisation Scientifique du Travail (C.E.G.O.S.), was to be used in computing product costs. This method was concerned with the allocation of indirect charges to product costs. These charges were to be accumulated in various accounting units or sections (such as a division of the enterprise or a specific activity like distribution). Then, section costs were charged to product costs using a chosen work unit (unite d’oeuvre) as basis of allocation (such as kilome­." In Accounting in France (RLE Accounting).
