Recovery of captured carbon dioxide (CO2) is considered the most energy-intensive stage postcombustion CO2 capture strategies by aqueous amines. In response, an optically transparent flow reactor with continuous in operando collection using light-absorbing, graphite-titania composite microparticles developed for energy-efficient solar desorption from saturated amine absorbents. The synthesized ...

The influence of tobacco-smoke-material (TSM) on the detachment of microparticles from surfaces by turbulent air flow was investigated experimentally. Both clean and dusty glass surfaces were subjected to TSM either before or after the deposition of 64 microm to 76 microm-diameter stainless steel microparticles onto the surfaces. The TSM was generated by mechanically puffing research-grade ciga...

background: activated normal platelets undergo many biochemical and morphological changes, some of which are apoptotic. platelet derived microparticles and shrinked platelets as hallmark of platelet activation and apoptosis disperse surfaces containing procoagulant activity around injured vessels and tissues. this study was conducted to determine microparticles formation and platelet shrinkage ...

AIMS Microparticles are membrane vesicles shed by cells upon activation and/or apoptosis. Microparticles are involved in several processes, including blood coagulation and thrombosis. In addition to their role in the regulation of lipid metabolism, peroxisome proliferator-activated receptor-γ (PPAR-γ) agonists exert other effects, both dependent on and independent of PPAR-γ activation. Some PPA...

Therapeutic angiogenesis has emerged as a promising strategy to treat various acute and chronic vascular diseases, and to enhance tissue repair and regeneration. 1 Common revascularization therapies include the administration of angiogenic factors, such as vascular endothelial growth factor (VEGF). 2 The success of these therapies greatly relies on the ability to control the spatial organizatio...

An instrument to directly measure the charge carried by a cell or a microparticle as well as mass-to-charge ratio of the cell/microparticle was developed for rapid mass distribution measurement. A successful mass spectrum with a record high mass has been demonstrated. In this article, the details of the construction and operation of the charge monitoring cell mass spectrometer are reported. Exa...

A novel bioactive sponge was created with a composite of type I collagen sponges or porous poly(e-caprolactone) (PCL) scaffolds, platelet-rich plasma (PRP), BMP2-loaded nanoporous silicon enclosure (NSE) microparticles, mineralizing peptide amphiphiles (PA), and mesenchymal stem cells (MSC). Primary MSC from cortical bone (CB)  tissue proved to form more and larger colony units, as well as prod...

Synthetic hydrogels represent an exciting avenue in the field of regenerative biomaterials given their injectability, orthogonally tunable mechanical properties, and potential for modular inclusion cellular cues. Separately, recent advances soluble factor release technology have facilitated control over milieu cell microenvironments via microparticles. A composite hydrogel incorporating both th...

An interdigitated electrode (IDE) array-based impedance sensor is developed for microparticle detection. The IDE is fabricated by photolithography, Ti/Au deposition, and dielectric deposition. With this microfabricated IDE array, we demonstrated a highly portable impedance sensing system with frequency analyzing circuits, DAQ, and LabVIEW. With samples containing various microparticle concentra...
