Can Nonpolar Polyisobutylenes be Measured by Electrospray Ionization Mass Spectrometry? Anion-Attachment Proved to be an Appropriate Method. [PDF]

, 2015
Polyisobutylenes (PIBs) with different end-groups including chlorine, exo-olefin, hydroxyl, and methyl prepared from aliphatic and aromatic initiators were studied by electrospray ionization mass spectrometry (ESI-MS).

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

Anionic ring-opening polymerization of isobutylene oxide initiated with potassium salts activated by 18-crown-6: Determination of mechanism and characterization of polyether monols and diols

eXPRESS Polymer Letters, 2022
Various potassium salts, i.e., KOH, HOC3H6OC3H6OK, CH3OK, i-PrOK, t-BuOK, CbK, and (Me3Si)2NK activated by 18-crown-6 appeared to be active initiators of first anionic polymerization of isobutylene oxide.

Liquid PV Module Encapsulation to Enable Circular Design

Progress in Photovoltaics: Research and Applications, EarlyView.
This study demonstrates a novel liquid encapsulation technology to enable circularity in c‐Si photovoltaic modules. The optical properties and power conversion efficiency of liquid encapsulation is similar to EVA encapsulation and better than air encapsulation.

Alumina Nanoclusters Additives for Upgraded Regenerated Oils

Chemical Engineering Transactions, 2023
In this work, alumina nanoclusters have been synthesized by a "wet chemistry" approach directly in a regenerated oil. The produced alumina nanoclusters have a quasi-spherical shape with diameter size < 20 nm.

What Is a Polyolefin? A Critical Overview of Ethylene Copolymers Used as Solar Photovoltaic Module Encapsulants

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 4, Page 367-395, April 2026.
Polyolefin encapsulants are gaining dominance in PV modules, yet confusion persists around PO, POE, and TPO definitions. This study clarifies terminology, reviews materials, and properties and proposes a taxonomy to improve understanding, communication, and reliability in solar module manufacturing.

Steric Pruning Unlocks Hierarchical Structuring, Thermochromism, C‐H/O Activation, and 6‐electron Redox Transmetalation in Planar Bismuth Triamides

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Reducing steric bulk unlocks remarkable new physical phenomena such as epitaxial and hierarchical ordering, thermochromism, C─H/O activation, and multi‐electron redox transmetalation in planar bismuth triamides. These have all been hidden by the classical use of bulky substituents in this area.

Characterization of Microplastics in Human Gastric Cancer and Control Tissues and Analysis of Associated Genetic Features

Advanced Healthcare Materials, Volume 15, Issue 10, 13 March 2026.
This study characterizes the presence of microplastics in human normal gastric, para‐tumor, and gastric tumor tissue and confirms the association between microplastic exposure and lymph node metastasis in gastric cancer. This study explores the transcriptomic changes induced by microplastic exposure, laying the foundation for further investigation into

How Particle Size Affects Consolidation Behavior, Strain and Properties of Li6PS5Cl Fast Ionic Conductors

Advanced Energy Materials, Volume 16, Issue 12, 25 March 2026.
The densification process of Li6PS5Cl powders with varying particles size distributions reveals differences in smaller and larger distributions. Higher strain is revealed for the smaller particle size distribution from X‐ray diffraction. Discrete element method simulations uncover that the reason for the higher strain is not the particle size itself ...
