The Effects of Electromagnetic Fields on Human Health: Recent Advances and Future

Abstract

The potential of electromagnetic fields (EMFs) for disease treatment and health enhancement has been actively pursued over the recent decades. This review first provides a general introduction about natural EMFs and related biological effects. Then the recent progress on the EMF treatment of some common diseases (such as cancer, diabetes, wound healing and neurological diseases, etc.) has been carefully reviewed and summarized. Yet, the blindness on the selection of therapeutic EMF parameters still hinders the broad ap-plication of EMF therapy. Moreover, the unclear mechanism of EMF function and poor reproducibility of experimental results also remain big challenges in the field of bioelectromagnetics. Bionics is a useful methodology that gains inspiration from nature to serve human life and industry. We have discussed the feasibility of applying bionic approach on the selection of therapeutic EMFs, which is based on the findings of natural EMFs. Finally, we advocate that the detailed information of EMFs and biological samples should be thoroughly rec-orded in future research and reported in publications. In addition, the publication of studies with negative results should also be allowed.

Thermally Activated Delayed Fluorescence Macrocycles for Organic Light‐Emitting Diodes

“…𝜋-Conjugated compounds have garnered significant attention as electroluminescent materials due to their remarkable charge carrier transport capabilities. [48] Among them, organic 𝜋-conjugated macrocyclic compounds stand out as particularly noteworthy materials. In comparison to conjugated polymer TADF materials, the configuration of D-A-D-A conjugated type macrocyclic TADF compounds circumvents the issue of batch-to-batch variability stemming from variations in polymer molecular weights.…”

Positive and Negative Effects of Administering a Magnetic Field to Patients with Rheumatoid Arthritis (RA)

“…Furthermore, PEMF increases collagen deposition and reduces vascular dysfunction while improving oxidation processes at the tissue level [ 19 , 31 ]. The use of magnetic fields to regulate inflammation and immune function is safer compared with other clinical immunosuppressive methods [ 32 , 33 ].…”

Modulating Backbone Conjugation of Polymeric Thermally Activated Delayed Fluorescence Emitters for High‐Efficiency Blue OLEDs

“…An ideal TADF emitter should be able to achieve both high EQE and low efficiency roll‐off simultaneously. [ 15,16 ] In this regard, the TADF conjugated polymers with emission ranging from green to red colors have achieved satisfactory results, [ 17–23 ] but the development of blue TADF conjugated polymers still falls far behind, [ 24–27 ] which is mainly due to the accumulation of long‐lived triplet excitons at high current density, resulting in a rapid roll‐off of device efficiency. [ 28,29 ] To facilitate an efficient RISC process for the utilization of triplet excitons, it is necessary to add host units to copolymerize with TADF units to adjust the energy gap between S 1 and T 1 .…”
