With the phasing out of lead-bearing solders, electrically conductive adhesives (ECAs) have been identified as one of the environmentally friendly alternatives to tin/lead (Sn/Pb) solders in electronics packaging applications. In particular, with the requirements for fine-pitch and high-performance interconnects in advanced packaging, nanoconductive adhesives are becoming more and more importan...

Development of nano and biotechnologies encouraged us to develop a concept of automated building, which will significantly reduce the many negative impacts of traditional construction on the environment. The paper describes the concept of Nanoto meter-scale building, a new way of building, which unfolds from the nano into the meter range. The concept is based on bionanorobots, producing buildin...

Single-crystal X-ray diffraction structures of organotin compounds bearing hemicarbonate and carbonate ligands were recently reviewed by us—“CO2 Derivatives Molecular Tin Compounds. Part 1: Hemicarbonato Carbonato Complexes”, Inorganics 2020, 8, 31—based on crystallographic data available from the Cambridge Structural Database. Interestingly, this first collection revealed that most listed isol...

A supported trimetallic nano catalyst and a fixed bed catalytic process have been developed for the conversion of CO2 + H2O (in the form of steam) + 1% H2 to alcohol and propyne The mixture of CO2 +H2O and H2 is passed over Ru:Mn:Ni nano catalyst dispersed on a high surface area antase titanium dioxide catalyst support at 773 K and at atmospheric pressure with the gas space velocity of 6000-700...

Titanium dioxide is widely used in the manufacturing of paints, varnishes, lacquer, paper, paperboard, printing inks, rubber, floor covering, and ceramics and so on. White titanium dioxide pigment has been produced by two main processes. The sulfate and the chloride processes. Each of these two routes requires different feedstocks. However, economic and environmental pressures are shifting ...

Objective(s): Due to nanocomposites antimicrobial properties, one of the most extensive usages of nano-products is in packing industry. Thus, the production of packages with nanotechnology can effectively prevent against a variety of microorganisms. In this study, the silicon dioxide nanoparticles the poly (lactic acid) PLA films on antimicrobial and permeability was investigated. Methods...

The platinum-rich intermetallic compounds GdPt2In and GdPt2Sn were synthesized by arc-melting of the elements and subsequent annealing. The structures were refined from single crystal X-ray diffractometer data: ZrPt2Al type, space group P63/mmc, a = 455.1(1), c = 899.3(3) pm, wR2 = 0.0361, 166 F2 values, 9 variables for GdPt2In, and a = 453.2(1), c = 906.5(2) pm, wR2 = 0.0915, 166 F2 values, 9 ...

The Fermi surface of rare-earth tritellurides sRTe3d is investigated in terms of the nesting-driven chargedensity wave formation using positron annihilation and first-principles linear muffin-tin orbital calculations. Fermi surface nesting is revealed as a strong candidate for driving charge-density wave formation in these compounds. The nesting vector obtained from positron annihilation experi...

Lead isotopic ratios of cassiterite, the dominant tin ore, evolve after crystallization through decay of uranium and thorium to lead. We show that the lead isotopic ratios of smelted tin at Rooiberg, South Africa, form an isochron that matches the known geological age of the Rooiberg cassiterite deposits. Since the lead isotopic ratios of several prehistoric tin and bronze artifacts throughout ...

This work reports on the fabrication of tin nanoclusters by sputtering and inert-gas condensation inside an ultrahigh vacuum compatible system. This technique allows to fine tune the size and yield of nanoclusters by controlling the nanocluster source parameters. The produced nanoclusters are deposited on SiO2/Si substrate with pre-formed electrical electrodes to produce a nanocluster device. T...
