Novel Fixable Instruments Used in Strabismus Surgery.

Purpose: To introduce the application of novel fixable instruments in strabismus surgery without surgical assistants.

Methods: Patients with strabismus requiring surgical treatment were recruited. Under general anesthesia all patients underwent surgery with the three novel kinds of fixable instruments without assistants.

Efficient NO Reduction against Alkali Poisoning over a Self-Protection Armor by Fabricating Surface Ce(SO) Species: Comparison to Commercial Vanadia Catalysts.

Resolving severe deactivation by alkali metals for selective catalytic reduction of NO with NH (NH-SCR) is challenging. Herein, surface Ce(SO) species as a self-protection armor originally exhibited antipoisoning of potassium over ceria-based catalysts. The self-protection armor was also effective for other alkali (Na), alkali-earth (Ca), and heavy (Pb) metals, considerably resolving the deactivation of ceria-based SCR catalysts in practical applications.

Tuning Microstructure and Mechanical Performance of a Co-Rich Transformation-Induced Plasticity High Entropy Alloy.

Multi-principal element alloys and high-entropy alloys (HEAs) are emerging metallic materials with unprecedented structures and properties for various applications. In this study, we tuned the microstructure and mechanical performance of a recently designed high-performance Co-rich TRIP-HEA via thermomechanical processing (TMP). The microstructures of the HEA after various TMP routines were characterized, and their correlation with room-temperature tensile performance was clarified.

Catalytic performance and mechanistic evaluation of sulfated CeO cubes for selective catalytic reduction of NO with ammonia.

Sulfated CeO cubes were prepared by the impregnation of CeO cubes by ammonium sulfates, and further evaluated in selective catalytic reduction of NO with ammonia (NH-SCR). Catalytic activity tests indicated that NO reduction conversions and N selectivity of sulfated CeO cubes could be significantly improved compared to pure CeO cubes. The synthesized sulfated CeO cubes were further characterized by atom-resolved high angle annular dark-field (HAADF) imaging, Fourier-transform infrared spectroscopy (FTIR) by pyridine adsorption, and temperature-programmed reduction by H (H-TPR).

Microstructure Refinement of a Transformation-Induced Plasticity High-Entropy Alloy.

High-entropy alloys (HEAs) have attracted extensive interest due to their unprecedented structure and mechanical performance. We recently proposed a series of novel corich twinning induced plasticity (TWIP) and transformation induced plasticity (TRIP) HEAs with superior tensile properties at room temperature; however, the hot deformation behavior has not been reported. Here, we investigated the dynamic recrystallization behavior and grain refinement of a representative TRIP-HEA, compressed at temperatures of 1123-1273 K with strain rates of 0.

Accommodation changes after strabismus surgery due to anterior ciliary vessel disruption.

Purpose: To evaluate monocular accommodation changes after strabismus surgery with and without anterior ciliary vessel preservation.

Methods: Sixty patients with horizontal concomitant strabismus who were scheduled to undergo monocular strabismus surgeries were randomly divided into two groups: A (without anterior ciliary vessel preservation) and B (with anterior ciliary vessel preservation). Group A was further divided into groups A1 (surgical eyes without anterior ciliary vessel preservation) and A2 (corresponding nonsurgical eyes).

Does the disruption of horizontal anterior ciliary vessels affect the blood-aqueous barrier function?

Purpose: To investigate the significance of the anterior ciliary vessels (ACVs) preservation during the conventional horizontal strabismus surgery.

Methods: Patients (≥ 8 years) with horizontal strabismus were randomly allocated into group 1 (with ACV preservation) and group 2 (without ACV preservation). The surgical eyes in group 1 were further divided into group A (one rectus muscle operated) and group B (two rectus muscles operated).
