A comparison study of Pd/In/Pd, Pd-In/Pd, and PdIn ohmic contacts to n-GaAs

Solid-State Electronics, 1995
Various deposition structures, Pd/In/Pd, Pd-In/Pd and PdIn, as ohmic contacts to n-GaAs were investigated. The codeposited contacts, Pd-In/Pd and PdIn have smooth surfaces, and their minimum specific contact resistances are 3 × 10−6 Ω-cm2 after annealing at 600°C for 10 s.

Understanding Pd–Pd Bond Length Variation in (PNP)Pd–Pd(PNP) Dimers

Inorganic Chemistry, 2013
Analysis of the structures of three (PNP)Pd-Pd(PNP) dimers [where PNP stands for anionic diarylamido/bis(phosphine) pincer ligands] has been carried out with the help of single-crystal X-ray diffractometry and density functional theory (DFT) calculations on isolated molecules.

Thermochemistry of Pd–In, Pd–Sn and Pd–Zn alloy systems

Thermochimica Acta, 2009
The standard enthalpy of formation of several Pd-M alloys (M= In, Sn and Zn) has been measured using a high temperature direct drop calorimeter. The reliability of the calorimetric results has been determined and supported by using different analytical techniques: light optical microscopy, scanning electron microscopy equipped with electron probe ...

PD-1/PD-L1 in Disease

Immunotherapy, 2017
Expression of PD-1 on T/B cells regulates peripheral tolerance and autoimmunity. Binding of PD-1 to its ligand, PD-L1, leads to protection against self-reactivity. In contrary, tumor cells have evolved immune escape mechanisms whereby overexpression of PD-L1 induces anergy and/or apoptosis of PD-1 positive T cells by interfering with T cell receptor ...

Exchange splitting in Pd, Pd(Fe) and Pd(Ni)

Journal of Physics F: Metal Physics, 1986
The de Haas-van Alphen effect has been used to investigate the exchange splitting on the X-ellipsoid sheet of the Fermi surface of Pd and dilute Pd(Fe) and Pd(Ni) alloys. In pure Pd the g-factor shows appreciable anisotropy which can be explained in terms of the spin-orbit interaction and an isotropic Stoner enhancement.

PD or not PD?

Neurology, 2003
For nearly two centuries, investigating the role of heredity in Parkinson disease (PD) has been challenging. Paradoxes abound. Clinical series report that at least 10 to 15% of patients have relatives with PD. Case-control studies report from 2- to 14-fold increased risk of PD if a first-degree relative has the disease.1,2⇓ Yet twin studies do not ...

The nature of close Pd⋯Pd and Pd⋯H(—C) contacts

Polyhedron, 1999
Abstract The preparations and crystal structures of [PdCl2(R-ahaz)] (ahaz=3-aminohexahydroazepine) and [PdCl2(R-etahaz)] (etahaz=N-ethyl-3-aminohexahydroazepine) are described. Both complexes crystallise with two independent molecules stacked in “dimeric” pairs with short Pd⋯Pd contacts.
