Key Challenges for Commercializing Perovskite–Silicon Tandem Solar Cells

open access: yesCarbon Energy, EarlyView.
This review discusses the scientific and technological challenges in advancing perovskite–silicon tandem solar cells (PSTSCs) from lab‐scale to commercial viability, focusing on long‐term stability, scalability, and economic feasibility. Key issues include intrinsic and extrinsic degradation factors, installation conditions, environmental impacts, and ...

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

open access: yesChemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Clinical Impact of Maximum Plasma Concentration of Busulfan in Pediatric Patients Undergoing Allogenic Hematopoietic Stem Cell Transplantation

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Busulfan's narrow therapeutic index and high pharmacokinetic (PK) variability warrant investigation of its exposure–toxicity relationship. We retrospectively analyzed 334 pediatric and young adult patients who underwent allogeneic hematopoietic stem cell transplantation at Seoul National University Children's Hospital between 2009 and 2020 and received

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

Embryonic development of the Mediterranean starfish Hacelia attenuata

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Changing patterns of colonisation and persistence during the wolf recolonisation of the human‐dominated Italian alpine region

open access: yesEcography, EarlyView.
Dynamic occupancy models are fundamental for understanding complex species recolonisation processes, as they allow the assessment of both colonisation and persistence probabilities over time. Using a dynamic occupancy model and a large‐scale multi‐year dataset on wolf presence collected in the Italian alpine region between 2014 and 2020, we analysed ...
