Self‐Assembled Inorganic Nanomembrane Tubes: Rolled‐Up Piezoelectrics for Microacoustic Wave‐Based Actuators and Sensors

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

open access: yesAdvanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

open access: yesAdvanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Perspectives of gated communities’ socio-spatial integration: the case of post-socialist Lithuania

open access: yesBelgeo, 2018
as a new style of residential development, gated communities appear to be a reflection of territorial and social segregation in the suburbs of post-socialist cities.

Gated communities i staden [PDF]

open access: yes, 2016
Det offentliga rummet utgör en viktig roll i staden. Det fungerar som stadens knutpunkt där mänskliga möten sker och kunskapsutbyten genereras. Det talas mycket om hur Gated Communities påverkar de boende i området men hur påverkas omgivningen, rättare ...

Gated communities: Definitions, causes and consequences [PDF]

open access: yes, 2010
Gated communities became an 'object of study' in the 1990s as social scientists observed their growth in several cities; they are now a feature of the urban landscape in most cities around the world. The expansion of gated communities has led to prolific

Role of the Recombination Zone in Organic Light‐Emitting Devices

open access: yesAdvanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

GATED COMMUNITIES AS A SYMBOL OF INEQUALITY

open access: yesTEME, 2023
This article takes the concept of gated communities to represent a special form of securitised housing, developed in the United States in the 20th century and popularised around the world in later years, and examines it as such. The neo-liberal society is an especially fertile ground for the development of this concept due to the unequal distribution ...

A Reproducible and Scalable Process for High Yield Mesenchymal Stromal Cell Extracellular Vesicles Production

open access: yesAdvanced Materials Technologies, EarlyView.
Mesenchymal stem cell derived extracellular vesicles (MSC‐EVs) are a promising therapeutic tool for regenerative medicine. However, the field lacks a reproducible high‐yield production method to answer the quantities needed for clinical translation.

A narrative review of gated communities and the transformative social impact in Middle Eastern Cities

open access: yesUrban, Planning and Transport Research
The rise of gated communities in the Middle East is vastly spreading, driven by socioeconomic fluctuations and a desire for exclusivity. This article aims to contribute to the scholarly debates on the socio-spatial impacts of gated communities by ...
