A wide-acceptance-angle spherical grid composed of numerous micro cylindrical holes was developed to be used for the retarding a display-type field analyzer (RFA) and enhance energy resolution ( E /? ). Each hole with diameter 50 µm depth 80 is directed center. The inner radius 40 mm. holed area corresponds an acceptance angle ±52°. RFA equipped estimated 2000 from measured Au 4 f photoemission...

This paper discusses the design of hybrid alkali-activated binders at ambient temperature, specifically development mixes based on ground granulated blast-furnace slag (GGBFS) with calcium aluminate cement (CAC) as an additive, aiming to obtain high early strength optimised Al incorporation, increased crosslinking and degree polymerisation. The effects 10 wt% CAC replacement GGBFS, activated so...

A retarding field energy analyzer (RFEA) has been designed and developed to measure ion energy distribution function (IEDF) in helicon plasma. To design RFEA, determination of shape, size of the analyzer orifice, choice of grid and their separations are discussed. The four grid energy analyzer assembly provides easy access of all internal mechanical components and electrical connections. Fundam...

In an earlier experiment Riley and Wallace (8) showed that 0.5 cc. M/IO propionaldehyde injected subcutaneously into mice twice weekly for the 16 weeks during which tumors from a previous injection of 0.5 mgm. benzpyrene were to be expected, reduced the tumor yield from 36 to 22 per cent. In tissue culture it has been demonstrated that the growth and cellular activity of chick periosteal fibrob...

Fourteen years after its Unilateral Declaration of Independence (UDI), Kosovo is not still an international legal personality. The major challenge that has neither recognition nor non-recognition but the withdrawal (WR) by countries hitherto recognised it UDI. Evidently, only stagnated retarding because WR some states. On 13 May 2022, Serbian Foreign Minister declared there four additional brin...

Abstract The surface properties of oxidic supports and their interaction with the supported metals play critical roles in governing catalytic activities oxide‐supported metal catalysts. When are on reducible oxides, dynamic reconstruction phenomena, including strong metal–support (SMSI) oxygen vacancy formation, complicate determination structural–functional relationship at active sites. Here, ...

Environmental Concern and depletion in petroleum reservoirs caused interest search of alternate energies for internal combustion engine. Waste plastic materials being non-biodegradable, can be suitably processed using pyrolysis to obtain liquid fraction which has properties like fuels. 20% oil (PO) blends with diesel may utilized engines. However, adding biodiesel by renewable nature reduces em...
