Self-Organized Protonic Conductive Nanochannel Arrays for Ultra-High-Density Data Storage.

While the highest-performing memristors currently available offer superior storage density and energy efficiency, their large-scale integration is hindered by the random distribution of filaments and nonuniform resistive switching in memory cells. Here, we demonstrate the self-organized synthesis of a type of two-dimensional protonic coordination polymers with high crystallinity and porosity. Hydrogen-bond networks containing proton carriers along its nanochannels enable uniform resistive switching down to the subnanoscale range.

The effect of enhanced recovery protocols on postoperative rehabilitation in orthopedic surgery patients.

Orthopedics is a critical hospital department that has experienced shifts in the spectrum of orthopedic conditions due to societal advancements in recent years. While surgical interventions are effective in restoring fracture function, perioperative care remains a key factor in optimizing patient recovery. This study aims to assess the impact of orthopedic rehabilitation care based on the enhanced recovery after surgery (ERAS) protocol on postoperative rehabilitation.

D-Histidine modulated chiral metal-organic frameworks for discriminating 3,4-Dihydroxyphenylalanine enantiomers based on a chemiluminescence quenching mode.

Background: Drug enantiomers often display distinguishable or even opposite pharmacological and toxicologic activities. Therefore it is of great necessity to discriminate enantiomers for guaranteeing safetyness and effectiveness of chiral drugs. Facile chiral discrimination has long been a noticeable challenge because of the minimal differences in physicochemical properties of enantiomers.

Application of MMP-2-responsive forming injectable hydrogel in preventing the recurrence of oral squamous cell carcinoma.

Oral squamous cell carcinoma is one of the most common types of cancer. Surgical resection is one of the most important treatments at present. However, patients often suffer from regional recurrence after surgery.

Relationship between parenting stress and behavioral and emotional problems in preschool children: A mediation effect analysis.

Background: Emotional reactions, such as anxiety, irritability, and aggressive behavior, have attracted clinical attention as behavioral and emotional problems in preschool-age children.

Aim: To investigate the current status of family rearing, parental stress, and behavioral and emotional problems of preschool children and to analyze the mediating effect of the current status of family rearing on parental stress and behavioral/emotional problems.

Methods: We use convenience sampling to select 258 preschool children in the physical examination center of our hospital from October 2021 to September 2023.
