X-ray photoelectron spectroscopy (XPS) has had a profound impact on the surface chemical analysis of polymers, particularly in the identification of chemical species resulting from surface treatments that render so-called “unbondable” or non-pola

The lung is particularly susceptible to reperfusion injury, both experimentally and clinically after transplantation. The extracellular-type preservation solution Celsior, which has been predominantly studied in cardiac preservation, has components d

Photopheresis is an immunoregulatory technique in which lymphocytes are reinfused after exposure to a photoactive compound (methoxsalen) and ultraviolet A light. We performed a preliminary study to assess the safety and efficacy of photopheresis in t

Quantification at the surface or in the near-surface region has been difficult to achieve for analytical techniques such as secondary ion mass spectrometry (SIMS) and total reflection x-ray fluorescence (TXRF). Ion implantation through a removable la

The use of water soluble flux (WSF) in soldering processes of electronics manufacture is desirable from environmental, economic, and technical standpoints. However, ineffective removal of WSF residues in post-solder cleaning procedures may give rise

Mean free paths for inelastic scattering (λ) of low energy electrons in poly(methylmethacrylate) (PMMA) have been determined by measuring Al Kα excited C 1s and Si 2s photoelectron signal intensities as a function of ellipsometrically determined th

Thin films of both polymeric and nonpolymeric organic solids turn optically dense and electrically conductive on irradiation with high energy ion beams (e.g., 2 MeV Ar+). The structural and chemical properties of these films were investigated by ultr

A new method is described for bonding gold to Teflon FEP, yielding high joint strength without affecting the electrical properties of the virgin polymer material. The method consists of depositing a 1000-A aluminum layer onto the Teflon by evaporatio

The compatibility of various compositions of polystyrene (PS)-poly (vinyl methyl ether) (PVME) films and the thermally induced phase separation of such mixtures have been studied using several methods. Density measurements indicate extensive mixing o
