With emerging demand of potable and wearable electronic devices, reliable flexible energy suppliers are inevitable. Polymer electrolyte membrane fuel cells (PEMFCs) attract great attention due to high density sustainability. However, non-bendability limits their application in devices. To make PEMFCs adaptable flexible, considerable efforts have been devoted developing various bendable componen...

this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....

ÐA heterogeneous distributed database environment integrates a set of autonomous database systems to provide global database functions. A flexible transaction approach has been proposed for the heterogeneous distributed database environments. In such an environment, flexible transactions can increase the failure resilience of global transactions by allowing alternate (but in some sense equivale...

In this paper, the thermal analysis of a membrane antenna structure is performed, and then, rigid-flexible coupling dynamic modeling control membrane-antenna-satellite system are studied with stress considered. The model derived based on finite element method by discretizing into 1D 2D elements. Considering stress, vibration modes obtained, hybrid coordinate method. To reduce caused attitude ma...

Emerging materials in the field of implantable sensors should meet the needs for biocompatibility; transparency; flexibility and integrability. In this work; we present an integrated approach for implementing flexible bio-sensors based on thin Parylene C films that serve both as flexible support substrates and as active H(+) sensing membranes within the same platform. Using standard micro-fabri...

Limited by the effective launch capacity of a rocket, deployable antenna is very important in design spaceborne array. Compared to traditional antenna, flexible coilable array has higher surface precision and better vibration control therefore more suitable for high frequency communication. In order minimize weight satellite reduce cost its launch, guideline geometry parameters crucial. Existin...

The analysis of tissue-specific genetic alterations depends on the selective procurement of homogeneous cell populations. Microbeam microdissection of membrane-mounted native tissue (MOMeNT) permits the rapid, selective, and low-contamination procurement of tumor or other cells from histological sections by non-thermic non-contact laser microdissection. Tissue sections are mounted on a specific...
