Synthesis of Amides from Amines and Esters Under Hydrothermal Conditions. [PDF]

ChemistryOpen
In this study, we explore the amide synthesis under hydrothermal conditions, using amines and esters as the starting materials. Proposed major pathway starts with ester hydrolysis, followed by condensation between carboxylic acids and amines. The amide yield is dependent on the substrate structure, solution pH, and the presence of dissolved metal salts.

Post-translational regulation of human D-3-phosphoglycerate dehydrogenase in Alzheimer's disease. [PDF]

Protein Sci
Abstract Emerging evidence suggests that sex‐specific differences in L‐serine (L‐Ser) metabolism play a key role in Alzheimer's disease (AD). While disruptions in amino acid balance are well known, recent findings point to a dimorphic regulation of the serine biosynthetic pathway.

Contact angle influence on the pull-in voltage of microswitches in the presence of capillary and quantum vacuum effects [PDF]

, 2007
Capillary condensation between the electrodes of microswitches influences the effective pull-in voltage in a manner that depends on the contact angle of the capillary meniscus and the presence of plate surface roughness.

Multiplicities and Transverse Energies in Central AA Collisions at RHIC and LHC from pQCD, Saturation and Hydrodynamics [PDF]

, 2001
We compute the particle multiplicities and transverse energies at central and nearly central AA collisions at RHIC and LHC. The initial state is computed from perturbative QCD supplemented by the conjecture of saturation of produced partons.

iTU-pSAT I: Istanbul Technical University Student Pico-Satellite Program

2007 3rd International Conference on Recent Advances in Space Technologies, 2007
ITU-pSAT I is the first student designed pico-satellite of Turkey to be launched in 2008 as a part of the international CubeSat program. It carries two experimental payloads; a low-resolution camera with onboard image pre-processing, and passive magnetic stabilization with a magnetic rod accompanied by a sensor board to examine its performance.
