Although the one-step separation of ethylene from C2 hydrocarbons remains a significant challenge, one-step C2 separation provides a revolutionary breakthrough in cost savings and efficient energy utilization. Recent advances in metal-organic frameworks (MOFs) for achieving one-step C2 separation have been widely recognized. In this work, for the first time, the potential relationship between the structure and properties of MOF materials previously used for one-step C2 separation was revealed from a mathematical statistical perspective.

Background: For patients with osteoporosis and rotator cuff tears, there is still no consensus on current treatment methods. The material, structure, and number of anchors have important effects on the repair outcome.
Purpose: To investigate the use of chitosan quaternary ammonium salt-coated nickel-titanium memory alloy (NTMA) anchors to treat rotator cuff injury in shoulders with osteoporosis in a rabbit osteoporosis model.
Nemaline myopathy (NM) is a rare congenital muscle disease that leads to muscle damage, resulting in muscle weakness and atrophy. Cases of scoliosis induced by muscle weakness and atrophy are exceedingly uncommon. The author clinically treated one patient with NM complicated by scoliosis and analyzed its clinical characteristics through a literature review.

Objective: To investigate the mid-term effect and complications of arthroscopic popliteal tendon suture in the treatment of lateral meniscus injury.
Methods: From January 2016 to December 2020, the data of 57 patients with lateral meniscus popliteal tendon injury treated by arthroscopic popliteal tendon suture fixation were retrospectively analyzed, including 35 males and 22 females, aged from 18 to 47 years old with an average of (32.9±7.
Due to the poor thermal stability of conventional separators, lithium-ion batteries require a suitable separator to maintain system safety for long-term cycling performance. It must have high porosity, superior electrolyte uptake ability, and good ion-conducting properties even at high temperatures. In this work, we demonstrate a novel composite membrane based on sandwiching of zeolitic imidazole frameworks-67 decorated cellulose acetate nanofibers (ZIF-67@CA) with electrospun poly(vinyl alcohol)/melamine (denoted as PVAM) nonwoven membranes.

Both and are cationic frameworks, and their BET surface areas are 301 and 446 m/g, respectively. By modification of the components of metal clusters, features a neutral framework, and the BET surface area is increased up to 808 m/g.

Purpose: To compare the clinical outcomes and retear rates after rotator cuff repair (RCR) between delaminated and non-delaminated tears.
Methods: This systematic review was conducted according to the preferred reporting items for systematic reviews and meta-analyses guidelines using the PubMed, Cochrane Library, the Web of Science and Embase databases. Only articles on arthroscopic RCR with clinical outcome scores and data on the number of rotator cuff retears and complete healing were included.
Background: Obesity influences the outcomes of orthopedic surgeries such as total knee arthroplasty and spinal surgery. However, the effect of obesity on the outcomes of rotator cuff repair is unknown. This systematic review and meta-analysis aimed to examine the effect of obesity on rotator cuff repair outcomes.

Superior labrum anterior posterior (SLAP) injury is a major challenge for orthopedic surgeons, due to the poor healing ability of the injured labrum. Although arthroscopic surgery is the gold standard for the treatment of SLAP injury, there are still disputes about the adaptation of different surgical techniques, the choice of anchors during operation, knotted or knotless anchors, and fixation methods. The authors believe that arthroscopic repair of SLAP lesions is effective for young patients with intact glenoid labrum(<35 years old) or with extensive activity, where single and knotless anchor is preferred.

This study aimed to determine the relationship between preoperative FI and the rate of re-tear and functional outcomes after rotator cuff repair.
Methods: Computerized databases, including PubMed, EMBASE, Web of Science, and Cochrane Library database were searched for studies published from the inception date to January 2022.
Objective: To investigate the method and clinical effects of the treatment of recurrent shoulder dislocation with severe glenoid injury by arthroscopic subscapularis augmentation.
Methods: From March 2019 to August 2020, 16 patients with recurrent dislocation of shoulder with severe glenoid injury underwent arthroscopic subscapularis augmentation, including 10 males and 6 females, aged from 18 to 50 years old with an average of (29.06±10.
Purpose: This systematic review and meta-analysis aimed to evaluate the correlation between increased critical shoulder angle (CSA) and higher retear rates and functional outcomes after arthroscopic rotator cuff repair (ARCR).
Methods: PubMed, Embase, Web of Science, and Cochrane Library databases published before January 2022 were comprehensively searched. Two reviewers independently reviewed the titles and abstracts using the specified criteria.
