Cranial anatomy and stratigraphy of a new specimen of the tyrannosaurine dinosaur Daspletosaurus from the Judith River Formation of Central Montana, USA [PDF]

open access: yesActa Palaeontologica Polonica
The tyrannosaurine Daspletosaurus contains three recognized species from the Campanian of Montana and Alberta: Daspletosaurus torosus, Daspletosaurus wilsoni, and Daspletosaurus horneri. The recently named D. wilsoni has been proposed to represent a

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Further desmostylian remains from the upper Oligocene of Vancouver Island, British Columbia, Canada

open access: yesActa Palaeontologica Polonica, 2023
The North Pacific rim was home to an extinct group of semiaquatic marine mammals, the order Desmostylia, which superficially resembled hippos. Desmostylians are an uncommon fossil vertebrate in most localities where they occur, and Oligocene taxa ...

Physical Cranial Characters of Wajak Man [PDF]

open access: yes, 2014
Human fossils from Wajak, or better known as Wajak Man which is noted as Wajak 1, have been discovered by von Rietschoten in 1888 during exploration prospecting activities at the marble mine area in Tulungagung. The Wajak 1 found in cave sediments during

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

open access: yesAdvanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.
