Lithiation of individual silicon nanoparticles was studied in real time with in situ transmission
electron microscopy. A strong size dependence of fracture was discovered; that is, there …

The hypothalamus regulates many aspects of energy homeostasis, adjusting both the drive
to eat and the expenditure of energy in response to a wide range of nutritional and other …

… Liu, and A. Kushima contributed equally to this work. Portions of this work were supported
by a Laboratory Directed Research and Development (LDRD) project at Sandia National …

We report the creation of a nanoscale electrochemical device inside a transmission electron
microscope—consisting of a single tin dioxide (SnO 2 ) nanowire anode, an ionic liquid …

Homochiral catalysts that can effect asymmetric transformations are invaluable in the
production of optically active molecules. Researchers are actively pursuing the design of new …

We report direct observation of an unexpected anisotropic swelling of Si nanowires during
lithiation against either a solid electrolyte with a lithium counter-electrode or a liquid …

Hadronic transitions of χ c J→ η c π+ π−(J= 0, 1, 2) are searched for using a sample of 1.06×
10 8 ψ (3686) events collected with the BESIII detector at the BEPCII storage ring. The η c is …

… Xiao Hua Liu … Xiao Hua Liu … SH, FF, XH, SZ and TZ performed MD simulations. XHL

Conjugated microporous polymers are a new class of porous materials with an extended π-conjugation
in an amorphous organic framework. Owing to the wide-ranging flexibility in the …

Using a sample of 1.06× 10 8 ψ′ decays collected by the BESIII detector, χ c 0 and χ c 2
decays into π 0 π 0 and η η are studied. The branching fraction results are Br (χ c 0→ π 0 π 0)=(…
