Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Selective Hydrogenation of Formamide to Methanol Over Supported Platinum Catalysts

open access: yesAngewandte Chemie, EarlyView.
Amine–CO2 adducts can be hydrogenated to formamides and subsequently to methanol under mild conditions (<150°C), establishing an integrated CO2 capture‐and‐conversion route in a heterogeneous system that directly links amine sorbent cycling with methanol synthesis.

Guide to the geology of Bradgate Park and Swithland Wood, Charnwood Forest [PDF]

open access: yes, 2010
Charnwood Forest is one of the few parts of England where there are exposures of ‘basement’ rocks dating back to Precambrian time. Its locally rugged topography is caused by these highly resistant rocks protruding as craggy knolls through a surrounding ...

The position of graptolites within Lower Palaeozoic planktic ecosystems. [PDF]

open access: yes, 1993
An integrated approach has been used to assess the palaeoecology of graptolites both as a discrete group and also as a part of the biota present within Ordovician and Silurian planktic realms.

Sulfide‐Based Electrolytes for All‐Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This review covers the structural features and synthesis strategies of sulfide‐based solid electrolytes, as well as critical challenges related to conductivity, interfacial and moisture stability, and scaling‐up for practical application in Sodium‐based All Solid‐State Batteries.

Topology‐Dependent Coke Formation in the Catalytic Pyrolysis of Phenol Over HFAU and HZSM‐5 Zeolites

open access: yesAngewandte Chemie, EarlyView.
The coke formation and speciation during the catalytic pyrolysis of lignin over different zeolite topologies were studied with a combination of operando EPR spectroscopy and ex situ pulsed techniques aided with DFT calculations. Operando EPR data showed that the coke formation in HFAU is fast compared to HZSM‐5.

Palaeoecological importance of trace fossils from the Permian, Jurassic and Cretaceous deposits of Mountainous Adygeya

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2015
Trace fossils may be of crucial importance for palaeoenvironmental reconstructions, which is demonstrated by example of new ichnological finds in Mountainous Adygeya.

Trace fossils of microbial colonization on Mars: Criteria for search and for sample return [PDF]

open access: yes
The recent discovery of microbial trace-fossil formation in the frigid Ross Desert of Antarctica suggests that early primitive life on Mars may have left behind similar signatures. These trace fossils are apparent as chemical or physical changes in rock (

Occurrence of Shorea Roxburgh ex C. F. Gaertner (Dipterocarpaceae) in the Neogene Siwalik forests of eastern Himalaya and its biogeography during the Cenozoic of Southeast Asia [PDF]

open access: yes, 2016
We report the occurrence of two leaf impressions and one leaf compression along with one winged fruit and two fruiting calyx lobes, resembling those of Shorea Roxburgh ex C. F.
