Analysis Of Squeeze Film Damping In Microdevices [PDF]
There are various energy dissipation mechanisms that affect the dynamic response of microstructures used in MEMS devices. A cumulative effect of such losses is captured by an important characteristic of the structure called Quality factor or Q-factor ...

Squeeze Film Theory for Micropolar Fluids
Needs’ experimental results on thin films deviate considerably from those predicted by the classical theory when the film thickness is less than 0.00127 mm.

Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

Three‐Layer‐Structured Garnet‐Dominant Composite Solid Electrolyte for Solid‐State Batteries
The three‐layer‐structured garnet‐dominant composite solid electrolyte (GD‐CSE) is designed for solid‐state batteries. The GD‐CSE is composed of over 80 wt. % contents of LGLZO. This three‐layer CSE has high ionic conductivity and high potential stability.

Holey‐structured, edge‐carboxylated graphene with a controlled specific surface area was synthesized using an environmentally friendly, CO2‐activated, KOH‐free ball‐milling process. ABSTRACT Graphene, notable for its high specific surface area, is ideal for catalyst support but faces challenges under harsh thermal catalytic conditions.

Microwave‐driven Ru@α‐Fe2O3 selectively upgrades real‐world post‐consumer mixed polyolefin waste into light olefins with high gas yields and olefin selectivity at markedly reduced temperatures compared with conventional thermal pyrolysis. Strong tolerance of additives and feed heterogeneity highlights an energy‐efficient and scalable route for circular

Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...
