Background Emergence of severe acute respiratory syndrome (SARS) from the winter of
2002 to the spring of 2003 has caused a serious threat to public health. Methods To evaluate …

A seroepidemiologic study was conducted in North China in 2003 to determine the neutralizing
antibody titer of severe acute respiratory syndrome (SARS) convalescent sera. A total of …

Rotational piezoelectric energy harvesters which can directly convert mechanical energy
into electrical energy are considered as one of the most attractive harvesters for self-powered …

In this paper, a multi-folded-beam piezoelectric energy harvester (MFB-PEH) was proposed
for low-power energy harvesting applications in wide frequency band, low frequency, and …

In this paper, a bio-based flame retardant PA-AR is synthesized, which endows PLA with
good flame retardant and crystallization properties, and at the same time promotes the …

Background The improvement of bone ingrowth into prosthesis and enhancement of the
combination of the range between the bone and prosthesis are important for long-term stability …

Background Hallux valgus (HV) deformity is closely correlated to the hypermobility of the
first metatarsal-cuneiform joint, but adequate understanding of the three-dimentional (3D) …

The fully biobased flame retardant, which is based on the green and convenient ionic reaction
of phytic acid (PA) and taurine (TA) in water, brings flame retardancy to polylactic acid (…

The high surface resistance of polymethyl methacrylate (PMMA) causes its poor antistatic
performance. Once the surface is rubbed, the electric charge will be accumulated, and the …

In this article, dimethyl methylphosphonate (DMMP) and methacrylamide (MAM) were used
as flame retardants to develop an efficient synergistic flame-retardant system of phosphorus …
