Toward a Green SPPS: The Use of an Innovative Mesoporous pDVB Support for Environmentally Friendly Solvents

open access: yesJournal of Peptide Science, Volume 31, Issue 8, August 2025.
A novel polymeric mesoporous support (pDVB) has been proposed with the aim of improving the efficiency and sustainability of SPPS. This new resin enables the use of a wider range of green solvents. ABSTRACT This study explores the use of a novel polymeric mesoporous support (pDVB) for solid‐phase peptide synthesis (SPPS), with the aim of improving the ...

Analysis of digital terrestrial television development in Taiwan [PDF]

open access: yes, 2012
The development of digital terrestrial television (DTT) plays an important role of digital convergence. However, a regulator need not only select a suitable DVB standard but also decide timing of transition between existing standard and new standard ...

Chemical Synthesis of Crustacean Insulin‐Like Peptide Using a Novel Method to Prevent Methionine Oxidation During Solid Phase Peptide Synthesis

open access: yesJournal of Peptide Science, Volume 31, Issue 8, August 2025.
When tetrahydrothiophene (THT) was added to the solvent in solid phase peptide synthesis (SPPS), the oxidation of Met to Met(O) was significantly decreased, and the yields of Met‐containing peptides improved. Using this method, we could synthesize an insulin‐like peptide identified in the kuruma shrimp Marsupenaeus japonicus.

Compact Bistatic Iterative Passive Radar Based on Terrestrial Digital Video Broadcasting Signals

open access: yesApplied Sciences
Passive radar has become very popular in recent years because it is usually undetectable, and countermeasures used to prevent its functioning are complex and, in general, easily identified.

Supramolecular Design of Polymeric Random Lasers

open access: yesAdvanced Optical Materials, Volume 13, Issue 20, July 11, 2025.
This research investigates the application of PolyHIPE scaffolds as scattering media inRLs. By modifying the scaffold's morphology, pore size, and surface chemistry, the dye distribution within the material is precisely controlled, achieving a tunable laser threshold.

Nanopore Sequencing Solves an Elusive Case of Sotos Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, Volume 197, Issue 7, July 2025.
ABSTRACT Sotos syndrome is a rare genetic disorder characterized by distinctive facial features, including a broad and prominent forehead, dolichocephaly, and learning disabilities ranging from mild to severe intellectual impairment. Affected individuals often show overgrowth in height and head circumference over two standard deviations.
