Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles
Chemistry – A European Journal, EarlyView.A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

Chemistry – A European Journal, EarlyView.One‐pot synthesis of asymmetric organic carbonates from CO2, methanol, and other alcohols was demonstrated in the presence of CeO2 catalyst and 2‐cyanopyridine dehydrant. This reaction proceeded through two reaction pathways—direct route via cross‐carboxylation and indirect route via production of DMC and subsequent transesterification.

Statistical downscaling of GCM simulations to Streamflow
Journal of Hydrology, 2001 A multi-tiered forecast procedure is employed to simulate real-time operational seasonal forecasts of categorized (below-normal, near-normal and above-normal) streamflow at the inlets of twelve dams of the Vaal and upper Tugela river catchments in South Africa.

Ecography, EarlyView.Earthworms, as ‘ecosystem engineers', play a crucial role in regulating ecosystem functions and shaping community structures. Due to climate change, earthworms face severe survival pressures and extinction risks. However, whether conservation efforts targeting aboveground biodiversity can cover the long‐neglected earthworm diversity remains unknown. To

Selecting CMIP5 GCMs for downscaling over multiple regions
Climate Dynamics, 2015 The unprecedented availability of 6-hourly data from a multi-model GCM ensemble in the CMIP5 data archive presents the new opportunity to dynamically downscale multiple GCMs to develop high-resolution climate projections relevant to detailed assessment ...

Food Chemistry International, EarlyView.Date syrup are used as sweetener in bread. Bread with date syrup had superior phenolic composition, better antioxidant properties and carbohydrate hydrolysing enzymes while bread with granulated sugar had higher predicted glyceamic index. The study concluded that date syrup could be the next though‐out ingredient for dual purpose in bread. ABSTRACT The
