Wang et al. first reported a high-flux TFNC-based UF membrane system containing a “nonporous” hydrophilic coating that was water permeable (Pebax or PVA), an electrospun nano-fibrous support, and a nonwoven microfibrous substrate (Fig. 14.9). The TFNC UF membrane was fabricated by cast coating with the separation material on the electrospun membrane. Results indicated that these unique hydrophilic TFNC membranes exhibited a very high flux (several times higher than conventional TFC-based UF membranes) and comparable high rejection ratio for oil-and-water emulsion separation. Interestingly, the permeability of TFNC UF membranes can be dramatically increased by introducing nanofillers (such as surface-oxidized multiwalled carbon nanotubes [MWCNTs] or cellulose nanofibers [CNs]) as a means to induce water channels in the barrier layer. For example, the addition of 1.3 wt% of CNs or 10 wt% of oxidized MWCNTs could increase permeability by two to three times with the similar rejection ratio of 99.8% for oil/water emulsion. Wang et al. also used electrospinning to fabricate a PVA-based substrate, followed by crosslinking to improve the structural stability and mechanical strength of the membrane. In addition, the applied fabricated membrane seems to be efficient in UF techniques because of low membrane fouling in nature. Yoon et al. demonstrated that after 24 h of operation, the permeate flux for the electrospun-based membrane remained stable, whereas a commercial UF membrane experienced severe flux decline. The success of the aforementioned TFNC UF membranes could be attributed partially to the unique characteristics of an electrospun scaffold with high porosity and interconnected pores and the utilization of a highly hydrophilic barrier layer (e.g., PVA).

This is where the substrate fits into the enzyme like a lock and key. The negative and positive parts of both the substrate and enzyme link the two together at the active site.

Challenge: To develop packaging to transport, ship and store fragile substrates in an environment isolated from oxygen and humidity while also protecting from ESD, particles and outgassing.
Solution: This project concerned designing inert storage conditions for fragile substrates. We started with a photomask compact made of an inherently dissipative polymer proven in the industry to protect against ESD, particles and outgassing. The unique AU standoff design reduces particle emitting abrasion by securely holding the substrate on the beveled edges without contacting the surface. The self-aligning features of the AU standoffs reduce the risk of misplacement during insertion and removal of the device.
Once the device was secured in the compact, we created optimal inert storage conditions by adding N2 Purge capability. Traditional quick connect couplings use springs that generate particles and require lubricant, both potential sources of contamination. To address these concerns, we designed a quick connect valve that utilizes an open hose and low flow system to purge the compact and isolate the fragile substrate from oxygen and humidity.

Love: the Moment of Arrest
Love ceases all forms of reactions;
No substrates to be dealt with or to be reacted upon;
All cease to be.
No Name.
No Depth.
No Image.
No Separation...
Because in the first place there was no synthesis to any form.
Love has no promise of security;
Love ceases to be true when it is used upon for a cause, a selfish cause,
A secret cause of a cunning mind, mind that faces not pain and questions of the unreal.
Love liberates the Lover and the Loved,
When both are eager to set the other free from bondage;
When both selflessly unmask themselves for the other,
And reveal what is what is.
Love cannot be paid for,
Cannot be written,
Cannot be love when the brain calls it Love.
Call it love when you cannot have words to phraseologize it,
When you cannot have images to picture it,
When you cannot anymore see what you want to see to associate with it.
Call it love when you are not a possessor nor a possessed,
When you are at its limitless sacredness,
With no tomorrow, no yesterday,
But just the moment of Arrest, today.
