Selective Transformation of Syngas into Gasoline-Range Hydrocarbons over Mesoporous H-ZSM-5-Supported Cobalt Nanoparticles
Bifunctional Fischer-Tropsch (FT) catalysts that couple uniform-sized Co nanoparticles for CO hydrogenation and mesoporous zeolites for hydrocracking/isomerization reactions were found to be promising for the direct production of gasoline-range (C5-11) hydrocarbons from syngas.

We present a synthetic strategy for the efficient encapsulation of a derivative of a well-defined cobaloxime proton reduction catalyst within a photoresponsive metal-organic framework (NH2-MIL-125(Ti)). The resulting hybrid system Co@MOF is demonstrated to be a robust heterogeneous composite material. Furthermore, Co@MOF is an efficient and fully recyclable noble metal-free catalyst system for light-driven hydrogen evolution from water under visible light illumination.

Beyond geometry: Shape entropy links nanostructures with emergent macroscopic behavior in natural and engineered systems
Now, materials science and chemical engineering researchers working with computer simulations of colloidal suspensions of hard nanoparticles at University of Michigan, Ann Arbor have linked entropy and emergence through a little-understood property they refer to as shape entropy - an emergent, entropic effect - unrelated to geometric entropy or topological entropy - that differs from and competes with intrinsic shape properties that arise from both the shape geometry and the material itself and affect surface, chemical and other intrinsic properties.

Scotland's Albatern is putting a new, modular spin on renewable energy generation. WaveNET is a scalable array of floating "Squid" generator units that harvest wave energy as their buoyant arms rise and fall with the motion of the waves.

In 2009, Rodney Allam sat down with a four-function calculator and began to model an emissions-free power generation cycle. Over the course of several months, he came out with pages of calculations and a crucial number, called net efficiency. This number indicated Allam's cycle was more efficient than existing power generating cycles, while at the same time, it captured 100 percent of carbon emissions. Now, 140 million [dollars] in investments later by some of the world's largest energy firms, a 25-person Durham business hopes to upend the entire energy industry.
