Una Musa 'esiodea' (Ar. Pax 774-780)

Myrtia
L’articolo individua un debito lessicale e concettuale verso Esiodo per l’invocazione alla Musa di Ar. Pax 774-780. Aristofane intende rappresentarsi come ‘poeta della pace’ e a tale scopo si rifà alla tradizione che ha origine con Esiodo e passa per ...

Synthesis of a Highly Porous Nitrogen-Doped Carbon Material from a Melamine/Formaldehyde Resin with Potassium Citrate

International Journal of Electrochemical Science, 2017
Nitrogen-doped porous carbons were synthesized from an aqueous solution of melamine and formaldehyde. The addition of potassium citrate to the solution mixture led to a tremendous increase in the surface area from 74 m2/g to 2718 m2/g, indicating that ...

Adiabatic mechanism of the multiply charged ion production by a laser field through ATI states of an atom

, 1996
ATI can be followed by an inelastic collision of the ionized electron with the parent atomic particle resulting in an excitation of the ion. It may be a continuum state excitation producing the doubly charged ion or a discrete state which also enhances ...

Strong Lateral Confinement of Hydrophilic Silica Nanoparticles on Mg‐Al Layered Double Hydroxides Nanoflakes for Enhanced Thermal Properties

Advanced Materials Interfaces, EarlyView.
A nanostructured, naturally flame‐retardant, and non‐toxic inorganic composite is introduced, which is laterally associated with silica nanoparticles to induce the restacking of the LDH lamella structure, thereby serving as an efficient thermal insulator.

Global versus local environmental impacts of grazing and confined beef production systems

Environmental Research Letters, 2013
Carbon footprint is a key indicator of the contribution of food production to climate change and its importance is increasing worldwide. Although it has been used as a sustainability index for assessing production systems, it does not take into account ...

Tuning the exciton g-factor in single InAs/InP quantum dots

, 2008
Photoluminescence data from single, self-assembled InAs/InP quantum dots in magnetic fields up to 7 T are presented. Exciton g-factors are obtained for dots of varying height, corresponding to ground state emission energies ranging from 780 meV to 1100 ...

Microwave Absorption for Detection of Dirac Fermions in SnTe Films

Advanced Materials Interfaces, EarlyView.
Microwave absorption can detect Dirac fermions in samples exposed to the atmosphere. Results showed that although topological surface states are robust against environmental degradation, they are not detectable by electrical transport measurements. Hence, microwave absorption can detect Dirac fermions even in samples whose surfaces have deteriorated ...

State Corporate Income Tax Credit for Federal Qualified Transportation Fringe Benefits [PDF]

, 2001
Both federal and state agencies have initiated tax policies intended to reduce commuter traffic in single occupancy vehicles (SOV). Currently the federal government allows employees to exempt up to $65 per month ($780 per year) in federally approved ...

Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge

Advanced Materials Technologies, EarlyView.
This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across
