Quantifying the shift of public export finance from fossil fuels to renewable energy.
Nat Commun

Climate Finance and Policy Group, ETH Zurich, Zurich, Switzerland.
By providing guarantees and direct lending, public export credit agencies (ECAs) de-risk and thus enable energy projects worldwide. Despite their importance for global greenhouse gas emission pathways, a systematic assessment of ECAs' role and financing patterns in the low-carbon energy transition is still needed. Using commercial transaction data, here we analyze 921 energy deals backed by ECAs from 31 OECD and non-OECD countries (excluding Canada) between 2013 and 2023.

This work is the first comprehensive survey of the Yangtze River, covering its origin to the estuary mouth. It focuses on the geographical and industrial factors influencing the distribution of polycyclic aromatic hydrocarbons (PAHs) in sediments, along with their contamination levels, sources, and ecological risks. The total concentrations of PAHs ranged from 2.

Solar hydrogen production using photoelectrochemical (PEC) cells requires the selection of cost-effective materials with high photoactivity and durability. CuBiO photocathodes possess an appropriate bandgap for efficient hydrogen production. However, their performance is limited by poor charge transport and interface voids formed due to the porous structure during annealing, which complicates the deposition of passivation overlayers.

Department of Orthopaedics and Traumatology, Istanbul School of Medicine, Istanbul University, Istanbul, Turkey.
Background: A population-based study delineating the epidemiologic, clinical, and treatment characteristics of femoral neck fractures (FNFs) in elderly patients has not yet been conducted in Turkey. In this nationwide study, the epidemiologic, clinical, and treatment characteristics of patients aged ⩾65 years with FNFs who underwent osteosynthesis, hemiarthroplasty (HA), or total hip arthroplasty (THA) were examined.
Methods: Patients aged ⩾65 years with FNFs were identified in this retrospective, nationwide study.
Effect of Nonsurgical Mechanical Debridement With or Without Chlorhexidine Formulations in the Treatment of Peri-Implant Mucositis. A Randomized Placebo-Controlled Clinical Trial.

Objectives: To evaluate the treatment of peri-implant mucositis (PM) using a nonsurgical submarginal peri-implant instrumentation (NSPI) with or without chlorhexidine (CHX) solutions.
Methods: Fifty-six patients (28 per group) were randomly assigned to the test (NSPI + 0.12% mouthwash and subgingival CHX irrigation plus tongue brushing with 1% CHX gel) or the control group (NSPI + placebo mouthwash and subgingival placebo irrigation plus tongue brushing with placebo gel).
