Evaluating Dielectric Properties for Semicrystalline Thermoplastics to Analyze the Thermal and Rheological Properties in Laser‐Based Powder Bed Fusion of Plastics

open access: yesAdvanced Engineering Materials, EarlyView.
This study aims to establish a link between the dielectric properties of polyamide 12 (PA12) and its thermal and rheological properties using dielectric analysis (DEA). A standardized methodology is introduced to determine melting and crystallization temperatures.

A Novel Protein‐Polysaccharide Oral Nanoemulsion Targeting Activated Hepatic Stellate Cells to Enhance the Therapeutic Effect of Pirfenidone on Fibrosis After Transarterial Chemoembolization for Liver Cancer

open access: yesAdvanced Functional Materials, EarlyView.
Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...

Aminopeptidase B can bioconvert L-type amino acid transporter 1 (LAT1)-utilizing amide prodrugs in the brain

open access: yesFrontiers in Pharmacology, 2022
A prodrug approach is a powerful method to temporarily change the physicochemical and thus, pharmacokinetic properties of drugs. However, in site-selective targeted prodrug delivery, tissue or cell-specific bioconverting enzyme is needed to be utilized ...

The formation of peptide-like molecules on interstellar dust grains [PDF]

open access: yes, 2018
Molecules with an amide functional group resemble peptide bonds, the molecular bridges that connect amino acids, and may thus be relevant in processes that lead to the formation of life. In this study, the solid state formation of some of the smallest amides is investigated in the laboratory.

Lower-rim ferrocenyl substituted calixarenes: new electrochemical sensors for anions

open access: yes, 1998
New ferrocene substituted calix[4 and 5]arenes have been prepared and the crystal structure of a lower-rim substituted bis ferrocene calix[4]arene (7) has been elucidated. The respective ferrocene/ferrocenium redox-couples of compounds 6 (a calix[4]arene

Analytical Rebridging Monte Carlo: Application to cis/trans Isomerization in Proline-Containing, Cyclic Peptides [PDF]

open access: yes, 1999
We present a new method, the analytical rebridging scheme, for Monte Carlo simulation of proline-containing, cyclic peptides. The cis/trans isomerization is accommodated by allowing for two states of the amide bond.

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Chemical Modification of Pectin and Polygalacturonic Acid: A Critical Review

open access: yesBioResources, 2021
Pectin, as a sustainable biopolymer with its two complementary functionalities (carboxyl and hydroxyl moieties) imparted in the α-1,4-galacturonic acid repeating unit, has gained increasing attention in the last few years.
