Light Activated Induction of Cuproptosis in Resistant Cancer Cells Using Polymeric BODIPY Nanoparticles for Photoactivated Chemotherapy

Advanced Functional Materials, EarlyView.
This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.

Characterization and Application of Urea-Formaldehyde-Furfural Co-condensed Resins as Wood Adhesives

BioResources, 2014
Furfural, as an organic compound derived from biomass materials, was used to partially substitute for formaldehyde in the synthesis of UF resin. Urea-formaldehyde-furfural co-condensed (UFFR) resins with different substitute ratios of furfural to ...

Measuring Method of Formaldehyde Emission for Plywood

Journal of the Korean Wood Science and Technology, 2010
합판의 경우에는 제조 시 접착제가 각 단판의 전체 면에 도포되는 것이 아니라 접착 면에만 도포되므로 접착층을 따라서 접착제가 분포하게 된다. 따라서 섬유판이나 파티클보드의 경우와는 달리 전체 표면을 통하여 포름알데히드가 방산되지 않고 접착층을 따라서 방산된다고 판단되어진다. 따라서 기존의 KS M 1998-4 : 2005 방법으로 포름알데히드방산량을 측정하는 방법이 적절하지 않을 수도 있다고 판단되었다. 이에 본 연구에서는 동일한 조건에서 제조한 합판을 4가지 측정 조건에 따라 포름알데히드방산량을 측정하여 이들의 상관관계를 검토하였다.

Quality of Plywood Bonded with Nanolignin-Enriched Cardanol-Formaldehyde Adhesive

Fibers
Cardanol is a derivative of cashew nut shell liquid (CNSL) and has the potential to be used when developing adhesives for wood boards. Adding nanostructures to adhesive can increase its bonding and reduce formaldehyde emission.

Graphene Nanosheet‐Based Mixed Proton‐Electron Conducting Membranes for Efficient Hydrogen Purification

Advanced Functional Materials, EarlyView.
A monolayer graphene/phosphoric‐acid mixed proton‐electron conducting membrane combines proton‐conducting nanoconfined acid channels with electron‐conducting graphene nanosheets for efficient high‐temperature hydrogen purification. The membrane achieves nearly 100% H2/CO2 selectivity and 69 GPU hydrogen permeance at 250°C, arising from synergistic ...

Designed Liquid Crystalline Nanoassemblies From Clinically Validated Polyunsaturated Lipids for Combined Antioxidant, Anti‐Apoptotic, and Neurotrophic Treatments

Advanced Healthcare Materials, EarlyView.
Ionizable lipid nanoparticles target multiple pathological pathways in neurodegeneration. The designed self‐assembled materials undergo a pH‐triggered structural transformation from a cubosome/hexosome coexistence to a hexosome phase, enhancing intracellular delivery of a multi‐target phytochemical formulation. The antioxidant‐loaded pH‐responsive LNPs
