Bergmann's rule: Why does body size increase with latitude?

Functional Ecology, Volume 40, Issue 4, Page 830-843, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Bergmann's rule describes the tendency for endothermic body size to increase with latitude, a pattern often attributed to climatic factors. However, the underlying developmental and evolutionary mechanisms remain debated.

Isocyanate toughening of pCBT/organoclay nanocomposites with exfoliated structure and enhanced mechanical properties

eXPRESS Polymer Letters, 2014
Cyclic butylene terephthalate (CBT®) is an interesting matrix material for the preparation of nanocomposites due to its very low, water-like melt viscosity which favours clay exfoliation. Nevertheless, polymerized CBT (pCBT) is inherently brittle.

California Temperature Since 1520 CE Shows Interactions in Extremes of Heat, Drought, and Fire

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Summer maximum temperatures (Tmax ${T}_{\text{max}}$) in the Sierra Nevada have risen rapidly since the turn of the 20th century, especially above 1,500 m where trends in the south exceed 3°C century−1. To place this warming into context, we developed a 504‐year reconstruction of growing‐season (April–September) Tmax ${T}_{\text{max}}$ (1520 ...

Synthesis, Properties, Applications and Challenges of Multicomponent Doped Organic Room Temperature Phosphorescence Materials

Aggregate, Volume 7, Issue 3, March 2026.
The multi‐component doping strategy, involving self‐assembly, host‐guest systems, and crystal engineering, has gained attention for its simplicity, cost‐effectiveness, structural diversity, and adjustable room‐temperature phosphorescence (RTP). This review summarizes and evaluates the progress in creating RTP materials using this strategy, highlighting

Svojstva tekuće i polikondenzirane UF smole modificirane s pMDI

Drvna industrija, 2014
The aim of this study was to determine the properties of liquid and cured UF (urea-formaldehyde) resin modified with pMDI (polymeric 4, 4′-methylenediphenyl isocyanate). Analyses showed that when introduced to liquid UF resin already at 10 %, its reactivity increases, which is reflected in a shortening of gel time and reduction of activation energy of ...

A Rationale for Going Back to the Future: Use of Disposable Spacers for Pressurised Metered Dose Inhalers

Pulmonary Medicine, 2015
The introduction of pressurised metered dose inhalers (MDIs) in the mid-1950s completely transformed respiratory treatment. Despite decades of availability and healthcare support and development of teaching aids and devices to promote better use, poor ...

Investigation of the molecular interactions in a pMDI formulation by atomic force microscopy

European Journal of Pharmaceutical Sciences, 2004
The forces of interaction between inhalable formoterol fumarate dihydrate particles, and the various components of a pressurised Metered Dose Inhaler (pMDI) (e.g. aluminium container, other drug particles and stabilising excipients) were investigated in isolation and combination in the model propellant 2H, 3H perfluoropentane (HPFP).
