Autism Overflows with Syntheses [PDF]
Neuropsychology Review, 2009 Editor: We were surprised to find our case study “Cross-modal extinction in a boy with severely autistic behaviour and high verbal intelligence” (Bonneh et al. 2008) impugned by Professor Waterhouse (2008) as an example of “unsynthesized and hoc theories” cluttering autism research.

Porous Materials for Atmospheric Water Harvesting
ChemistryOpen, 2023 Atmospheric Water Harvesting (AWH) using porous adsorbents is emerging as a promising solution to combat water shortage. Thus, a clearer understanding of the developing trends and optimization strategies of different porous adsorbents can be extremely ...

, 2002 Despite the high quality reached by today's CG tree generators, there exists no realistic model for generating the appearance of bark: simple texture maps are generally used, showing obvious flaws if the tree is not entirely painted by an artist. Beyond modeling the appearance of bark, difficulty lies in adapting the bark features to the age of each ...

DFT Study on the Mechanism of Iron-Catalyzed Diazocarbonylation
Molecules, 2020 The mechanism of the carbonylation of diazomethane in the presence of iron–carbonyl–phosphine catalysts has been investigated by means of DFT calculations at the M06/def-TZVP//B97D3/def2-TZVP level of theory, in combination with the SMD solvation method.
