Biodegradable hydrogels have emerged as an important class of biomaterials for controlled drug delivery. The release rate of an excipient is determined by drug and polymer properties, such as the swellability, degradability, porosity, permeability, and hydrophilicity of the hydrogels. Smart (or intellig...

(Fig.1c) when the backbone is highly accurate and considerably improves over template-based methods even when strong templates are available. The all-atom accuracy of AlphaFold was 1.5 Å r.m.s.d.95(95% confidence interval = 1.2–1.6 Å) compared with the 3.5 Å r.m.s.d.95(95%...
Thin films are ubiquitous in modern technology and highly useful in materials discovery and design. For achieving optimal extrinsic properties, their microstructure needs to be controlled in a multi-parameter space, which usually requires too high a 
Stereoselectivity leads to the formation of an uneven mixture of stereoisomers (isomeric molecules that have the same molecular formula but different tridimensional atom orientations in space). In addition, the reaction is exothermic. Lindlar's Catalyst Examples Using the Lindlar catalyst 1-phenyl...
