The ease of assembly of a given peptide sequence is hard to predict, which makes peptide synthesis challenging. Review methods and reagents for avoiding aggregation in solid-phase peptide synthesis.
Use the calculator to determine the boiling point or pressure of solvents based on the Antoine Equation and see solvent attributes. View a list of products based on the solvent CAS number.
The conductivity of organic semiconductors can be increased, and the barriers to charge-carrier injection from other materials can be reduced, by the use of highly reducing or oxidizing species to n- or p-dope, respectively, the semiconductor.
Advances in the electrochemical conversion of water to and from hydrogen and oxygen have principally been achieved through the development of new materials and by understanding the mechanisms of the degradation of proton exchange membrane fuel cells (PEMFC) during operation.
The effects of the mononuclear cell separation method described by Bøyum procedure are noted below, since research situations may arise in which they are significant.
A simplified LC-MS/MS method to determine glyphosate and related compounds using a Supel™ Carbon LC U/HPLC column for stability under higher pH conditions and sufficient retention for the polar analytes in the presence of methanol as an extraction solvent.
Poly(2-oxazoline)s (POx) can be viewed as conformational isomers of polypeptides. They are synthesized via living cationic ringopening polymerization (LCROP) of 2-oxazolines and were almost simultaneously discovered in 1966 by the groups of Litt, Tomalia, Fukui and Seeliger.
Sustainable, environment-friendly, and clean energy sources with sufficiently high production efficiency for practical application are highly desirable to meet the energy challenge of the 21st century due to the world′s increasing energy demand.
We have explored novel transparent oxide semiconductors, focusing on the low dimensional structure embedded in the crystal structure: in particular, a 3-dimensionally (3D) connected nanometer sized cage structure and a 2-dimensional (2D) layered structure composed of a narrow gap semiconductor
Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.
Biomaterials science involves the design and fabrication of smart materials for studying, directing, or mimicking biology. For successful integration of biomaterials in biological research, a meaningful understanding of biological systems is required.
Guidelines for various bioassays on the MultiScreen system, which makes it possible to carry out an assay from sample incubation to scintillation counting in a 96-well plate.
Biomedical implants are essentially foreign substances within the human body that must survive many years’ exposure to demanding mechanical and physiological conditions. Despite these challenges, metal implants have been widely used to substitute for or rebuild hard tissues such as
The odor and pungency of ginger is due to the presence of terpenes, gingerols and shogaols. These compounds contribute to the highly complex matrix of ginger, which subsequently presents a challenge in low level analyses of contaminants. A novel 2-layer
