“…Most emulsions encompass immiscible phases of water and an organic phase while some emulsions consist of both organic phases (non-aqueous) with a difference in their polarities, including amides (formamide or dimethylformamide), glycols (ethylene glycols), poly-alcohols (glycerol), lower alcohols (methanol), alkylated sulfoxides [dimethyl sulfoxide (DMSO),] and acetonitrile or their solutions. [31] When emulsions containing an organic phase are used in producing highly porous materials for a variety of applications, the complete removal of the organic phase requires the use of more organic solvents for washing or an energy-consuming vacuum process. Both approaches are not environmentally friendly.…”

“…Most of the emulsions consist of an aqueous phase and an oil (hydrocarbon) phase, but emulsions composed of two non‐aqueous (organic) phases or two aqueous phases have also been introduced. [ 23 , 24 , 31 , 32 ] Emulsions are usually formed by the dropwise addition of one phase into another under stirring (or homogenization, vortex) [ 32 ] but can also be simply prepared by shaking and mixing of two immiscible liquids ( Figure 2 a,b ). [ 33 ] Another method to instantly form emulsions by shaking involves the use of water‐soluble porous polymer.…”

“…[ 32 , 35 , 36 ] A surfactant is a substance containing hydrophobic and hydrophilic groups, also known as a stabilizer or an emulsifier, usually added to prepare an emulsion. [ 31 , 32 ] To further improve emulsion stability, additional surfactants (known as co‐surfactant or co‐stabilizer) can also be introduced into the emulsions. These surfactant molecules are located at the interface of the two liquid phases and form a protective film to minimize the chances of emulsion destabilization while impeding droplet coalescence pertaining to the reduced interfacial tension of small droplets.…”

Emulsion templating is at the forefront of producing a wide array of porous materials that offers interconnected porous structure, easy permeability, homogeneous flow-through, high diffusion rates, convective mass transfer, and direct accessibility to interact with atoms/ions/molecules throughout the exterior and interior of the bulk. These interesting features together with easily available ingredients, facile preparation methods, flexible pore-size tuning protocols, controlled surface modification strategies, good physicochemical and dimensional stability, lightweight, convenient processing and subsequent recovery, superior pollutants remediation/monitoring performance, and decent recyclability underscore the benchmark potential of the emulsion-templated porous materials in large-scale practical environmental applications. To this end, many research breakthroughs in emulsion templating technique witnessed by the recent achievements have been widely unfolded and currently being extensively explored to address many of the environmental challenges. Taking into account the burgeoning progress of the emulsion-templated porous materials in the environmental field, this review article provides a conceptual overview of emulsions and emulsion templating technique, sums up the general procedures to design and fabricate many state-of-the-art emulsion-templated porous materials, and presents a critical overview of their marked momentum in adsorption, separation, disinfection, catalysis/degradation, capture, and sensing of the inorganic, organic and biological contaminants in water and air.

“…One of the effective way to realize SF operation is to use a multi-arm grazing incidence coupled cavity (Fox-Smith coupled cavity). 11 This cavity has better mode selection than the conventional GIC and operates at a lower threshold. A conventional GIC was created between the mirrors (21) and (25) via a first order diffraction from the grating, with the zero order diffraction forming the output.…”

We present the design of a Cr:forsterite based single-frequency master-oscillator power-amplifier (MOPA) laser system delivering much higher output energy compared to previous literature reports. The system has four amplifying stages with two-pass configuration each, thus enabling the generation of 24 mJ output energy in the spectral region around 1262 nm. It is demonstrated that the presented Cr:forsterite amplifier preserves high spectral and pulse quality allowing a straightforward energy scaling. This laser system is a promising tool for tunable nonlinear down-conversion to the midinfrared (MIR) spectral range, and will be a key building block in a system for high-resolution muonic hydrogen spectroscopy in the 6.8 micron range.

An InGaN laser diode operating at 398 nm and with output facet coated with a multi-layer anti-reflection coating has been operated within Littrow external cavities. A maximum manual tuning range of 6.3 nm has been achieved and a continuous tuning range of 0.8 GHz with a single piezo control. Stable single-longitudinal-mode operation has been obtained with a linewidth less than 11 MHz. The effects on total tuning range due to the orientation of the diode output facet within the Littrow cavity are discussed.
