Relationship between duration of QRS complex in ECG and echocardiographic ejection fraction in patients with Left bundle Branch Block

open access: yesمجله دانشگاه علوم پزشکی گرگان, 2005
Background&Objective: Prolongation of QRS duration particularly in Left bundle Branch Block (LBBB) is commonly associated with many cardiac diseases. Electrocardiographic study of QRS duration and electrical axis may be predictors of sever LV systolic ...

Structural Colors from Ultrathin Lignin Films

open access: yesAdvanced Optical Materials, EarlyView.
Thickness‐dependent structural colors in ultrathin lignin films generate a full visible palette, tuned simply by solution concentration and spin speed. Abstract Structural colors offer a sustainable alternative to toxic pigments and dyes, yet their realization from lignin, the most abundant aromatic biopolymer, has remained elusive.

On–Off Switchable Micromotors for Use in Steerable Microvehicles

open access: yesAdvanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,
