Re-entrant transition as a bridge of broken ergodicity in confined monolayers of hexagonal prisms and cylinders.

The entropy-driven monolayer assembly of hexagonal prisms and cylinders was studied under hard slit confinement. At the conditions investigated, the particles have two distinct and dynamically disconnected rotational states: unflipped and flipped, depending on whether their circular/hexagonal face is parallel or perpendicular to the wall plane. Importantly, these two rotational states cast distinct projection areas over the wall plane that favor either hexagonal or tetragonal packing.

Processing-Structure-Performance Relationships of Microporous Metal-Organic Polymers for Size-Selective Separations.

Small-molecule impurities, such as -nitrosodimethylamine (NDMA), have infiltrated the generic drug industry, leading to recalls in commonly prescribed blood pressure and stomach drugs in over 43 countries since 2018 and directly affecting tens of millions of patients. One promising strategy to remove small-molecule impurities like NDMA from drug molecules is by size exclusion, in which the contaminant is removed by selective adsorption onto a (micro)porous material due to its smaller size. However, current solution-phase size-exclusion separations are primarily limited by the throughput-selectivity trade-off.

Porous cage-derived nanomaterial inks for direct and internal three-dimensional printing.

The convergence of 3D printing techniques and nanomaterials is generating a compelling opportunity space to create advanced materials with multiscale structural control and hierarchical functionalities. While most nanoparticles consist of a dense material, less attention has been payed to 3D printing of nanoparticles with intrinsic porosity. Here, we combine ultrasmall (about 10 nm) silica nanocages with digital light processing technique for the direct 3D printing of hierarchically porous parts with arbitrary shapes, as well as tunable internal structures and high surface area.

Bilateral corneal keloids after eyelid compression.

The purpose of this study is to present a case of bilateral corneal keloids after performing eyelid compression for half a year. This study was a retrospective case report. Visual acuity, as well as detailed high-resolution images of external eye photography, anterior segment optical coherence tomography (ASOCT), and topography were documented.

Adenine inhibits growth of hepatocellular carcinoma cells via AMPK-mediated S phase arrest and apoptotic cascade.

Adenine exhibits potential anticancer activity against several types of malignancies. However, whether adenine has anticancer effects on hepatocellular carcinoma (HCC) cells is incompletely explored. Human HCC cell lines HepG2 and SK-Hep-1 (p53-wild type) and Hep3B (p53-deficient) were used as cell model.

A novel technique for closed-chamber iridodialysis repair.

Purpose: We introduce a novel technique for closed chamber iridodialysis repair.

Materials And Methods: We use a 2.8-mm paracentesis knife to penetrate into the anterior chamber and create interrupted incisions in the sclera.

Toxic Keratopathy Following the Use of Alcohol-Containing Antiseptics in Nonocular Surgery.

Importance: Corneal abrasion is the most common ocular complication associated with nonocular surgery, but toxic keratopathy is rare.

Observation: Three patients developed severe toxic keratopathy after orofacial surgery on the left side with general anesthesia. All patients underwent surgery in the right lateral tilt position with ocular protection but reported irritation and redness in their right eyes after the operation.
