Cadmium and Zinc‐Doped p‐type Sb2Se3 Single Crystals and Solar Cells

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Cd and Zn were assessed as candidate p‐type dopants in Sb2Se3 single crystals in concentrations between 1016‐1020 cm−3. Both are effective in inducing p‐type conductivity, however Cd doped crystals exhibit lower resistivity across a wider range of dopant levels.

The Role of Certifications in Improving Household Food Security Among Peruvian Farmers

open access: yesAgribusiness, EarlyView.
ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.

Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation

open access: yesAngewandte Chemie, EarlyView.
Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...

Prognostic Utility of the Preoperative Cachexia Index in Patients Undergoing Emergency Laparotomy

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
The preoperative cachexia index, incorporating muscle mass, nutritional status, and inflammation, predicts in‐hospital and one‐year mortality in patients undergoing emergency laparotomy. This simple index may aid in risk stratification and perioperative decision‐making in high‐risk surgical patients. ABSTRACT Aim Emergency laparotomy is associated with

Tetraaza[7]–[15]helicenes Synthesized by Two‐Step Strategy: Length‐Controlled Chiral π‐Systems Exhibiting Amplified Circularly Polarized Luminescence

open access: yesAngewandte Chemie, EarlyView.
A modular two‐step strategy provides tetraaza[n]helicenes (n = 7–15) as a homologous series with tunable photophysical and chiroptical properties. Extension beyond n = 11 induces pronounced through‐space π–π interactions, narrowing the energy gap and amplifying circularly polarized luminescence.

The Influence of Surgeons' Gender on Surgical Outcomes in Laparoscopic Right Hemicolectomy: A Japanese Nationwide Retrospective Cohort Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study analyzed 58 503 laparoscopic right hemicolectomies for colon cancer in Japan between 2018 and 2022, comparing outcomes between male and female surgeons. No significant differences were found in surgical mortality or severe complications. Tailored surgical training programs for female surgeons may further enhance surgical outcomes.

Host‐Guest Doping Enables Room Temperature Phosphorescence from Triarylboranes

open access: yesAngewandte Chemie, EarlyView.
While pure triarylboranes show RTP in annealed PMMA films, they do not in crystalline form, contrary to our previous report. However, crystalline host‐guest triarylborane systems show persistent afterglow up to 8 s even at 1 ppb guest loading. Computations identify triplet‐triplet energy transfer as the mechanism governing this efficient RTP.
