	abstract = {Vanadium dioxide (VO2) based thermochromic smart window is considered as the most promising approach for economizing building energy consumption. However, the high phase transition temperature (τc), low luminous transmission (Tlum), and solar modulation (ΔTsol) impose an invertible challenge for commercialization. Currently, smart window research surprisingly assumes that the sunlight radiates in one direction which is obviously not valid as most regions receive solar radiation at various angles in different seasons. For the first time, solar elevation angle is considered and 3D printing technology is employed to fabricate tilted microstructures for modulating solar transmission dynamically. To maximize energy-saving performance, the architecture of the structures (tilt, thickness, spacing, and width) and tungsten (W) doped VO2 can be custom-designed according to the solar elevation angle variation at the midday between seasons and tackle the issue of compromised Tlum and ΔTsol with W-doping. The energy consumption simulations in different cities prove the efficiency of such dynamic modulation. This first attempt to adaptively regulate the solar modulation by considering the solar elevation angle together with one of the best reported thermochromic properties (τc = 40 {\textdegree}C, Tlum(average) = 40.8\%, ΔTsol = 23.3\%) may open a new era of real-world-scenario smart window research.},

Due to their morphological characteristics, mainly the tunable, ordered nanometric pores, they can be utilized as supporting hosts for confined chemical reactions. Applications of these materials, however, are limited by structural design. Here, we present a new approach for the 3D printing of complex geometry silica objects with an ordered mesoporous structure by stereolithography. The process uses photocurable liquid compositions that contain a structure-directing agent, silica precursors, and elastomer-forming monomers that, after printing and calcination, form porous silica monoliths. The objects have extremely high surface area, 1900 m2/g, and very low density and are thermally and chemically stable. This work enables the formation of ordered porous objects having complex geometries that can be utilized in applications in both the industry and academia, overcoming the structural limitations associated with traditional processing methods.},

The effect of CNT concentration and the type of the binder and its ratios to the CNT were investigated. Coatings based on water dispersions give higher adsorption, but solvent-based coatings enable achieving lower emittance. Interestingly, the binder was found to be responsible for the high emittance, yet, it is essential for obtaining good adhesion to the SS substrate. The best performance of the coatings requires adjusting the concentration of the CNTs and their ratio to the binder to obtain the highest absorptance with excellent adhesion; high absorptance is obtained at high CNT concentration, while good adhesion requires a minimum ratio between the binder/CNT; however, increasing the binder concentration increases the emissivity. The best coatings have an absorptance of ca. 90\% with an emittance of ca. 0.3 and excellent adhesion to stainless steel.},

Despite receiving numerous exertions on design and fabrication technique, smart windows have rarely been commercially employed in the building industry due to unreliable lifetime, poor heat switching performance as well as high fabrication costs. Herein, we introduce a novel strategy in designing smart glass device, which focuses on the development of functionalized MxSnO2 nano-frameworks for electrochromic coating. The hybrid structures based on such nano-frameworks do not change the amorphous nature of electrodeposited tungsten trioxide (ɑ-WO3) layer and therefore are able to preserve its excellent electrochromic properties. Novel hybrid nano-structures of MxSnO2/ɑ-WO3 are able to encompass all desired features of a smart window, including the ability to block more than 95\% NIR radiation in colored state while still allow about 80\% of visible light transmittance in bleached state, rapid electro-optical response time of about 10 s and improved coloration efficiencies. More importantly, the advanced MxSnO2/ɑ-WO3 nanostructures can also retain their structure and functionality for at least 1000 switching cycles due to the enhanced binding strength. In addition, the synthetic recipe of such functionalized nano-framework is facile and cost-effective, enabling the fabrication on any template type and size.},

The 3D-printed monoliths with 50 wt\% zeolite loadings exhibit Cs and Sr uptake with an equivalent ion-capacity as their pristine powders.

Results showed that loaded nanoemulsions were found to be non-cytotoxic under the conditions of the study. Furthermore, no oxidative stress induction was observed. Likewise, an efficacy test of these loaded nanoemulsions was also tested on human skin organ cultures, before and after ultraviolet B light treatment. Viability and caspase-3 production assessment, in response to the exposure of skin explants to the loaded nanoemulsions, indicated non-toxic effects on human skin in culture, both with and without ultraviolet B irradiation. Further the ability of loaded nanoemulsions to protect the skin against ultraviolet B damage was assessed on skin explants reducing significantly the apoptotic activation after ultraviolet B irradiation. Our promising results indicate that the developed loaded nanoemulsions may represent a topical drug delivery system to be used as an alternative treatment for recurrent skin diseases.},

	abstract = {Coordination polymers (CPs) and coordination network solids such as metal-organic frameworks (MOFs) have gained increasing interest during recent years due to their unique properties and potential applications. Preparing 3D printed structures using CP would provide many advantages towards utilization in fields such as catalysis and sensing. So far, functional 3D structures were printed mostly by dispersing pre-synthesized particles of CPs and MOFs within a polymerizable carrier. This resulted in a CP active material dispersed within a 3D polymeric object, which may obstruct or impede the intrinsic properties of the CP. Here, we present a new concept for obtaining 3D free-standing objects solely composed of CP material, starting from coordination metal complexes as the monomeric building blocks, and utilizing the 3D printer itself as a tool to in situ synthesize a coordination polymer during printing, and to shape it into a 3D object, simultaneously. To demonstrate this, a 3D-shaped nickel tetra-acrylamide monomeric complex composed solely of the CP without a binder was successfully prepared using our direct print-and-form approach. We expect that this work will open new directions and unlimited potential in additive manufacturing and utilization of CPs.},

	abstract = {By designing an actuator composed of thin layers with different coefficients of thermal expansion (CTE) together with an electrically conductive layer, the CTE mismatch can be utilized to produce soft electrothermal actuators (ETAs). These actuators have been typically implemented using only two layers, commonly relying on Timoshenko{\textquoteright}s analytic model that correlates the temperature to the actuator{\textquoteright}s curvature. In this study, we extend the analytic model to include the thermoelectric relation present in ETAs, that is, the conductive layer{\textquoteright}s properties with respect to the operation temperature. By applying the thermoelectric relation, a minimal voltage optimization can be applied to the analytic model. Using dimensionless analysis, we optimize the ETAs performance for both bi- A nd tri-layer ETAs with and without the thermal modeling. The bi-layer optimization not only predicts the maximal value for the bi-layer performance but also provides the optimal thickness of each layer for any couple of materials. We validate the tri-layer analytic model experimentally by measuring the curvature for different third layer thicknesses. Finally, we optimize the tri-layer design based on the analytic model, which can achieve an improvement in curvature per voltage of >3000\% over the optimal bi-layer ETA.},
