Sebastian has no hesitation to reply in a timely manner to students outside of his teaching time which is especially important if the students face roadblocks in their work. As a result of Sebastian's efforts, my daughter did very well in the subject for her O-level examinations. I highly...
This clear, concise Complete Revision & Practice book from CGP is a perfect way to prepare for the Edexcel AS-Level Chemistry exams (it also covers every Year 1 topic from the full Edexcel A-Level Chemistry course). It's fully up-to-date for the new exam specifications for 2015 and beyo...
As a result, the PMCN-SEI protected Li metal anode enables the Li || Li symmetric batteries to maintain over 300 cycles (1300 h) at a capacity of 5 mA h cm-2, corresponding to a cumulative capacity of 3.25 Ah cm-2. Moreover, Li-S batteries assembled with 20 Lm of Li metal anode...
Water–oxide interfaces are ubiquitous in nature, yet a molecular-level understanding of these complex environments is still lacking. Now, using in situ nonlinear optical spectroscopy, unconventional reaction pathways have been revealed during the structural evolution of a silicon oxide surface in liquid...

Transition metal selenides are regarded as prospective conversion-reaction anodes for potassium-ion bat-teries (PIBs) because of their relatively high electrical conductivity, large theoretical specific capacity, abundant resources and low cost. The challenge of the metal selenides originates from a ser...
