Strain Effects on Melting of Thermally Induced Crystals in Polyisoprene Rubber

open access: yesJournal of Polymer Science, EarlyView.
The melting temperature (Tm) of thermally induced crystals (TICs) in synthetic cis‐1,4‐polyisoprene rubber (IR) slightly increases (~4 K) upon stretching, accompanied by peak broadening, indicating destabilization of the rubbery state and a broader crystal size distribution.

A walk in the park—Identifying healthy greenspaces using scents

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
As urbanisation accelerates globally, access to nature is increasingly recognised as vital for public health and wellbeing. We captured and analysed plant‐emitted airborne ‘scent signatures’ across Oxford's urban greenspaces to assess their potential health relevance.

Natural Products as Modulators of ABC Transporters in Breast Cancer

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Breast cancer remains a significant global health challenge, with high incidence and mortality rates despite advancements in early detection and treatment. Multidrug resistance (MDR), particularly in aggressive subtypes like triple‐negative breast cancer (TNBC), continues to hinder effective therapy.

A global perspective on aerosol from low-volatility organic compounds [PDF]

open access: yes, 2010
Global production of organic aerosol from primary emissions of semivolatile (SVOCs) and intermediate (IVOCs) volatility organic compounds is estimated using the global chemical transport model, GEOS-Chem. SVOC oxidation is predicted to be a larger global

XV. On isoprene and caoutchine [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London
Abstract The products of the destructive distillation of caoutchouc have been studied by several chemists. The results at present obtained are, however, quite irreconcileable. Gregory appears to have been the first to direct attention to them, but it is evident that even at the time of writing his 'Handbook of Organic Chemistry’ he ...

Renewable Energy‐Driven Green Electricity Supplement for Empowering Blue Economy

open access: yesSusMat, EarlyView.
In order to support the blue economy to expand to the distant sea, this work proposes the framework driven by renewable energy. It integrates flexible perovskite solar cells, triboelectric nanogenerator‐supercapacitors, grid‐forming control strategies, and AI‐driven digital engines.

Measurements of Isoprene-Derived Organosulfates in Ambient Aerosols by Aerosol Time-of-Flight Mass Spectrometry—Part 2: Temporal Variability and Formation Mechanisms [PDF]

open access: yes, 2011
Organosulfate species have recently gained attention for their potentially significant contribution to secondary organic aerosol (SOA); however, their temporal behavior in the ambient atmosphere has not been probed in detail. In this work, organosulfates

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

open access: yesInsect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.
