High Charge Carrier Mobility in Non‐Conjugated 3D Covalent Organic Frameworks

open access: yesAdvanced Materials, EarlyView.
A non‐conjugated 3D COF constructed via boronate ester linkages from tetraphenylene and pyrene‐based monomers is reported, which exhibits a high charge carrier mobility of 14 ± 1 cm2 V−1 s−1. ABSTRACT π‐Conjugation, π–π stacking, and long‐range order play a central role in determining charge transport efficiency in organic materials.

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

open access: yesAdvanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

A Hypothetical Cohort Model of Human Development [PDF]

open access: yes
This research provides a model of growth of the human development index (HDI) by examining past changes and levels of HDI and creates four ÒcohortsÓ of countries. Using a hypothetical cohort approach reveals a model of HDI growth.

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

open access: yesAdvanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

open access: yesAdvanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

The development and validation of the Alzheimer’s Disease Caregiver Reported‐Health Index (ADCR‐HI): a disease‐specific caregiver‐reported outcome measure for use in clinical trials

open access: yesAlzheimer's & Dementia
AbstractBackgroundIn preparation for therapeutic trails involving patients with Alzheimer’s disease (AD) and mild cognitive impairment (MCI), there is a need for valid, disease‐specific caregiver‐reported outcome (CRO) measures capable of tracking symptomatic burden in response to therapy over time.

Risk prevention for HV transformers: Beyond the health index

open access: yes, 2016
An innovative tool to prevent the negative consequences of unexpected failure of HV transformers may be based on the risk evaluation. This risk is formed by three partial components, which are: causes of failure, probability that a failure may provoke a ...
