Influence of metal–semiconductor interface treatments and absorber structure on the performance and reliability of uni-traveling-carrier photodiodes (UTC-PDs)

Scientific Reports
The effects of absorber structure–controlled by adjusting the thickness ratio of doped and undoped InGaAs layers–and metal-semiconductor interface treatment methods were investigated in waveguide-type UTC-PDs. Ultraviolet-ozone (UVO) and ammonia solution

RaPID Selection of Backbone Macrocyclic Peptides Targeting Akt2

Angewandte Chemie, EarlyView.
Backbone macrocyclic peptide library (BMP) library was screened against Akt2 via RaPID to discover potent BMPPakti‐3 (IC50 = 34 nM). ABSTRACT Backbone‐cyclic peptides (BMPs) are an attractive class of molecules appeared in diverse natural bioactive products. However, mRNA display technology coupled with ribosomal synthesis is intrinsically inapplicable
