A flexible and cost-effective methodology to develop compact flow devices with heat exchange ability is presented here.
Additive manufacturing techniques allows the rapid design and manufacturing of modular jacketed flow ...
Modification of polyetherimide membranes with ZIFs fillers for CO2 separation
(Elsevier, 2019)
Flat hybrid membranes composed of polyetherimide (PEI) as matrix and zeolitic imidazolate frameworks (ZIFs) as fillers at concentrations of 10 and 20 wt% were prepared. Apparent permeability coefficient and apparent ...
Enhanced Conductivity of Composite Membranes Based on Sulfonated Poly(Ether Ether Ketone) (SPEEK) with Zeolitic Imidazolate Frameworks (ZIFs)
(MDPI, 2018)
The zeolitic imidazolate frameworks (ZIFs) ZIF-8, ZIF-67, and a Zn/Co bimetallic mixture
(ZMix) were synthesized and used as fillers in the preparation of composite sulfonated poly(ether
ether ketone) (SPEEK) membranes. ...
Engineered Diffraction Gratings for Acoustic Cloaking
(American Physical Society, 2019)
We show that engineered diffraction gratings can considerably simplify the design of acoustic ground
cloaking devices. Acoustic reflecting gratings are designed in such a way that all the incident energy is
channeled ...
Combining Modulated Techniques for the Analysis of Photosensitive Devices
(Wiley-VCH GmbH, 2021-09-03)
Small-perturbation techniques such as impedance spectroscopy (IS), inten-sity-modulated photocurrent spectroscopy (IMPS), and intensity-modulated photovoltage spectroscopy (IMVS) are useful tools to characterize and model ...
High sampling rate single-pixel digital holography system employing a DMD and phase-encoded patterns
(Optical Society of America, 2018)
A single-pixel digital holography system with phase-encoded illumination using a
digital micromirror device (DMD) as a spatial light modulator (SLM) is presented. The
enhanced switching rate of DMDs, far exceeding the ...
Structural characterization of bulk and nanoparticle lead halide perovskite thin films by (S)TEM techniques
(IOP Publishing, 2019)
Lead halide (APbX3) perovskites, in polycrystalline thin films but also perovskite nanoparticles (NPs) has demonstrated excellent performance to implement a new generation of photovoltaic and photonic devices. The structural ...
Beyond the energy balance: Exergy analysis of an industrial roller kiln firing porcelain tiles
(Elsevier, 2019-03)
The ceramic tile manufacturing process consumes large amounts of energy, mainly in the firing stage. Firing usually takes place in natural gas-fuelled continuous roller kilns, the most widely used tile firing facilities ...
Fast compressive Raman bio-imaging via matrix completion
(Optical Society of America, 2019)
Raman microscopy is a powerful method combining non-invasiveness with no special sample preparation. Because of
this remarkable simplicity, it has been widely exploited in many fields, ranging from life and materials ...
Potassium ions as a kinetic controller in ionic double layers for hysteresis-free perovskite solar cells
(Royal Society of Chemistry, 2019-07-22)
Since ion migration and interaction with external contacts has been regarded as one of the origins for photocurrent density (J)–voltage (V) hysteresis and phase segregation in perovskite solar cells (PSCs) under operational ...
