CO-Free Ethylene Oxide Production via Liquid-Phase Epoxidation with FeO/MSM Catalyst.

In this study, we present an approach for ethylene oxide (EO) production that addresses environmental concerns by eliminating greenhouse gas emissions. Our catalyst, FeO/MSM, was synthesized using a hydrothermal method, incorporating FeO nanoparticles into a well-structured mesoporous silica matrix (MSM). We selected peracetic acid as the oxidant, enabling CO-free EO production while yielding valuable by-products such as acetic acid, monoethylene glycol, and diethylene glycol.

In Situ Spontaneous Fabrication of Tough and Stretchable Polyurethane-Polyethyleneimine Hydrogels Selectively Triggered by CO.

CO -triggered in situ hydrogels is developed from waterborne poly(ε-caprolactone)-based polyurethane (PU) dispersion and aqueous polyethyleneimine (PEI) solution without any other chemicals and apparatus (e.g., UV light).

Fabrication of Microfiber-Templated Microfluidic Chips with Microfibrous Channels for High Throughput and Continuous Production of Nanoscale Droplets.

A polydimethylsiloxane (PDMS) microfluidic chip with well-interconnected microfibrous channels was fabricated by using an electrospun poly(ε-caprolactone) (PCL) microfibrous matrix and 3D-printed pattern as templates. The microfiber-templated microfluidic chip (MTMC) was used to produce nanoscale emulsions and spheres through multiple emulsification at many small micro-orifice junctions among microfibrous channels. The emulsion formation mechanisms in the MTMC were the cross-junction dripping or Y-junction splitting at the micro-orifice junctions.

Retroscleral implantation technique for porous polyethylene orbital implant after evisceration.

The authors developed a technique for the retroscleral implantation of a porous polyethylene orbital implant after evisceration for the placement of an adequately large orbital implant without wound tension. The surgical results of the technique in 27 patients are reported. The technique involves the severance of the optic nerve after standard evisceration and the insertion of the orbital implant into the retroscleral and intraconal space through the side of the scleral shell.

Effect of basic fibroblast growth factor on fibrovascular ingrowth into porous polyethylene anophthalmic socket implants.

To investigate the effect of basic Fibroblast Growth Factor (bFGF) on fibrovascular ingrowth into porous polyethylene orbital implants (Medpor) and to investigate any differences according to the method of administration. For the treated groups, after evisceration and Medpor implantation, bFGF was administered by soaking Medpor in the bFGF solution, and/or by injecting bFGF into the Medpor 1 week after the operation. Implants were removed 4 weeks after the operation and examined for the degrees of fibrovascular ingrowth by light microscopy.

Persistent diplopia after retrobulbar anesthesia.

Purpose: To determine the causative factors of persistent diplopia after retrobulbar anesthesia.

Setting: Strabismus Section, Department of Ophthalmology, Seoul National University, Seoul, South Korea.

Methods: Prism and alternate cover tests in the diagnostic positions of gaze and ductions/versions were performed in 28 patients with persistent diplopia 6 months after retrobulbar anesthesia.

Thyroid disease and vertical rectus muscle overaction after retrobulbar anesthesia.

Purpose: To determine the associated factors of persistent diplopia after retrobulbar anesthesia.

Setting: Strabismus Section, Department of Ophthalmology, Seoul Municipal Boramae Hospital, Seoul, Korea.

Methods: A prism and cover test in the diagnostic positions of gaze, force-generation test, and forced-duction test were performed in 11 patients with vertical rectus overaction after retrobulbar anesthesia.
