Achiral organic materials show nearly negligible orbit angular momentum, whereas organic ferrimagnets with chirality and reduced electron–lattice scattering could fundamentally bridge the gap between ferromagnetism and antiferromagnetism in the rapidly emerging field of ferrimagnetic spintronics. In this work, we report enantiomeric organic chiral ferrimagnets, where the chirality results from the molecular torsion by propeller-like arrangement of the donor and acceptor molecules. The ferrimagnetism results from the difference in electron–phonon coupling of the donor and acceptor inside the chiral crystals. Because the spin polarization is significantly dependent on the chirality, the magnetization of right-handed organic chiral ferrimagnetic crystals is larger than that of left-handed ones by 300% at 10 K. In addition, the processes of both excitation and recombination are strongly related to spin, phonon, and chiral orbit in these chiral ferrimagnets. Overall, both the organic chiral ferrimagnetism and spin chiroptical activities may substantially enrich the field of organic spintronics.

Modulation of the electronic and magnetic structure of blue phosphorene nanoribbons to explore the potential application in spintronics is appealing.

Background Current studies did not draw definitive conclusions on comparison of intracorporeal anastomosis (ICA) with extracorporeal anastomosis (ECA) in laparoscopic right colectomy. Whether the intraperitoneal contamination induced by ICA can result in higher risk of postoperative abdominal infection remains unclear. This study was aimed to compare the short‐term outcomes, especially the risk of abdominal infection after ICA versus ECA. Methods This was an observational cohort study as a secondary analysis of a randomized controlled trial (RCT)—RELARC trial (NCT02619942). The patients enrolled in the RELARC trial were diagnosed with primary colon adenocarcinoma without distant metastasis and underwent radical laparoscopic right colectomy between Jan 2016 and Dec 2019. In our study the patients who converted to open surgery in RELARC trial were excluded. The short‐term outcomes were compared between ICA and ECA. The primary endpoint was abdominal infection. The inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) was used for adjusting the potential confounders. Results This study enrolled 975 patients with 119 patients undergoing ICA and 856 patients undergoing ECA. The incidence of abdominal infection was higher in ICA group (9.2% versus 1.5%, RR from IPTW = 5.7 (95%CI: 2.6–12.6), P < 0.001) as well as the incidence of wound infection (14.3% vs 3.3%, RR from IPTW = 5.0 (95%CI: 2.9–8.6), P < 0.001). ICA was associated with higher incidence of Clavien–Dindo (CD) grade I and II complications (CD‐I: 15.1% versus 6.8%, RR from IPTW = 2.4 (95%CI: 1.5–3.9), P < 0.001; CD‐II: 26.9% versus 8.2%, RR from IPTW = 3.6 (95%CI: 2.5–5.1), P < 0.001) but similar incidence of CD‐III ~ IV complications compared to ECA (3.4% vs 2.1%, RR from IPTW = 1.2 (95%CI: 0.4–4.0), P = 0.73). In ICA group, choosing another incision rather than lengthening main port site decreased the incidence of wound infection although without statistical significance (17.3% (14/81) versus 7.9% (3/38), crude RR = 2.2 (95%CI: 0.7–7.2), P = 0.17). Conclusion ICA is likely to be associated with higher risk of abdominal infection and CD‐I ~ II complications.

The organic magnetoelectric complexes are beneficial for the development on flexible magnetoelectric devices in the future. In this work, we fabricated all organic multiferroic ferromagnetic/ferroelectric complexes to study magnetoelectric coupling at room temperature. Under the stimulus of external magnetic field, the localization of charge inside organic ferromagnets will be enhanced to affect spin–dipole interaction at organic multiferroic interfaces, where overall ferroelectric polarization is tuned to present an organic magnetoelectric coupling. Moreover, the magnetoelectric coupling of the organic ferromagnetic/ferroelectric complex is tightly dependent on incident light intensity. Decreasing light intensity, the dominated interfacial interaction will switch from spin–dipole to dipole–dipole interaction, which leads to the magnetoelectric coefficient changing from positive to negative in organic multiferroic magnetoelectric complexes.
