Cu2ZnSnS4 (CZTS) is a promising quaternary semiconducting absorber layer in thin film heterojunction solar cells. All the elements of this compound semiconductor were abundant, inexpensive, and non-toxic, hence CZTS is an alternative emerging optoelectronic material for Cu(In,Ga)Se2 and CdTe solar cells. Using the traditional spray approach, these films were effectively grown at an ideal substrate temperature of 643 K. The deposited films are found to be a kesterite structure using X-ray diffraction studies. The lattice parameters are calculated from the XRD spectrum and are found to be a = b = 5.44 Å and c = 10.86 Å. The energy band gap and optical absorption coefficient are found to be 1.50 eV and above 104 cm-1 respectively. The material exhibits p-type conductivity. After the chemical spray pyrolysis is completed, the deposited films remain on the hot plate, thus improving the films' crystallinity. A Cu2ZnSnS4 solar cell is fabricated using entirely chemical synthesis methods. The

Skoltech engineers have used a 3D printer to fabricate — and investigate the mechanical characteristics of — samples of bronze-steel alloys previously unknown to materials science. Blending the distinct properties of bronze and steel, the novel alloys could be used to manufacture combustion chambers for aircraft and rocket engines. These would benefit from both steel’s ability to withstand extreme temperatures and bronze’s capacity to conduct heat away from the chamber
This SAE Aerospace Report (AIR) provides a cross reference for SAE material standards to other similar standards. The SAE Committee G-3 invites comments and recommendations for the addition of materials and information for inclusion into this informational report. No attempt has been made to obtain samples of the materials or conduct physical and chemical analyses to determine if they are equivalent. Anyone using this AIR, therefore, is cautioned to verify for themselves the interchangeabillity of the specific materials. Additional contributions of missing or supplemental data should be directed to SAE marked for the attention of Committee G-3

This standard defines the requirements for fully replacing undesirable surface finishes using robotic hot solder dip. Requirements for qualifying and testing the refinished piece parts are also included. This standard covers the replacement of pure tin and Pb-free tin alloy finishes with SnPb finishes with the intent of subsequent assembly with SnPb solder. This dipping is different from dipping to within some distance of the body for the purposes of solderability; solder dipping for purposes other than full replacement of pure tin and Pb-free tin alloy finishes are beyond the scope of this document. It covers process and testing requirements for robotic dipping process and does not cover semi-automatic or purely manual dipping processes. This standard does not apply to piece-part manufacturers who build piece parts with a hot solder dip finish. It applies to refinishing performed by a robotic hot solder dip service supplier or production facilities at the customer, whenever the intent
G-24 Pb-free Risk Management Committee for ADHP
This document provides risk mitigation for Pb-free solders used internal to parts used in Aerospace and Defense applications. It will include mitigations applicable to encapsulated and cavity devices as the needs arise in industry. Currently this revision only addresses devices with encapsulation or underfill. Mitigations for open cavity devices are still being discussed, and will be addressed in future revisions. Microbumps with Thermal Compression Bonding (TCB) are not addressed by the mitigations in this document. The use of Pb-free microbumps with TCB are considered out of scope at this time. It is expected that this document will be primarily used by Control Levels 3 and 2C (as defined in GEIA-STD-0005-2 for programs that do not allow use of Pb-free tin or only allow its use on an exception basis). It may be used by other levels, or by applications not using GEIA-STD-0005-2

The bearing performance of steel backed half bearings, bushings, and washers is dependent on the properties and thickness of the lining alloy, the strength and dimensional stability of the steel backing (usually SAE 1010) and the strength of the bond between the lining alloy and the backing. This SAE Information Report is primarily concerned with the properties of the lining alloys used in automotive applications, in particular, the crankshaft bearings of the internal combustion engine

Tin sulfides (SnS and SnS2), represent a safer and greener alternative to other metal sulfides such as copper sulfides, and MoS2 etc. Their behavior is usually associated to that of solid lubricants such as graphite. A mixture of tin sulfides, with the 65 wt% of SnS2, has been characterized by scanning electron microscopy and by thermal gravimetric analysis (TGA). In order to investigate the effect of tin sulfides upon two crucial friction material ingredients, two mixtures were prepared: the former was made by mixing tin sulfides with a natural flake graphite and the latter was made mixing tin sulfides with a straight novolak. They were analyzed by TGA and differential thermal analysis (DTA) in both nitrogen and air. Some interferences were detected between tin sulfides and graphite in air. However, the oxidation of tin sulfides was concomitant with that of the novolak so that the resin onset decomposition-oxidation was considerably shifted to higher temperatures allowing the resin to
