“…After the samples were treated with HF for 10 s, the average sizes of the nanogaps between the Ag nanoparticles increasde from 33 to 36 nm and from 2 to 3.5 nm for sputtering times of 30 and 60s, respectively. However, for the 90 s cosputtered samples, the irregular defects are caused by the thick Ag–SiO 2 composite films with weak adhesion to the substrate, leading to uneven film damage caused by HF corrosion. , …”

“…However, for the 90 s cosputtered samples, the irregular defects are caused by the thick Ag−SiO 2 composite films with weak adhesion to the substrate, leading to uneven film damage caused by HF corrosion. 39,40 Figure S4(a) shows the SERS spectra for the 30, 60, and 90 s samples before and after the 10 s HF treatment. Compared with the original samples, the SERS of HF-etched samples is significantly improved, indicating the important role of the medium in SERS enhancement.…”

It is very important to build uniform large-area dense hotspots to improve the surface-enhanced Raman scattering (SERS) detection limit. In our research, we designed and prepared a new flexibile SERS substrate with ultradense hot spots that has the advantages of high sensitivity, good repeatability, easy fabrication, and low cost. Due to the special dense hot spot structure, the substrate reaches a SERS enhancement factor of 2.1 × 1011. Because of the excellent physical stability of polydimethylsiloxane, the substrate can be bent at will, and the SERS performance will not change with bending. This is very important to extract effective detection objects on complex surfaces. The substrate has good light transmittance and softness and can be directly attached to the detected agricultural products to realize real-time and rapid SERS monitoring. This structure exhibits extraordinary performance for thiram detection in the ultralow concentration range of 10–13 M.

“…One of the most important applications of Li is in energy storage as Li-ion batteries, which are the most promising electrochemical energy storage devices [ 161 ]. Electrotherapy creates new opportunities in wound healing [ 162 ], and wearable ionic triboelectric nanogenerator (iTENG) patches (created from a stretchable platform based on LiCl-loaded organogels and elastomeric microtubular structures) utilized the therapeutic effects of Li-ions in wound healing, and moreover contributed to creating and transmitting electrical stimulation ( Figure 4 ) [ 163 ], which is very promising in wound healing applications [ 164 ].…”

Lithium (Li) is a metal with critical therapeutic properties ranging from the treatment of bipolar depression to antibacterial, anticancer, antiviral and pro-regenerative effects. This element can be incorporated into the structure of various biomaterials through the inclusion of Li chloride/carbonate into polymeric matrices or being doped in bioceramics. The biocompatibility and multifunctionality of Li-doped bioceramics present many opportunities for biomedical researchers and clinicians. Li-doped bioceramics (capable of immunomodulation) have been used extensively for bone and tooth regeneration, and they have great potential for cartilage/nerve regeneration, osteochondral repair, and wound healing. The synergistic effect of Li in combination with other anticancer drugs as well as the anticancer properties of Li underline the rationale that bioceramics doped with Li may be impactful in cancer treatments. The role of Li in autophagy may explain its impact in regenerative, antiviral, and anticancer research. The combination of Li-doped bioceramics with polymers can provide new biomaterials with suitable flexibility, especially as bio-ink used in 3D printing for clinical applications of tissue engineering. Such Li-doped biomaterials have significant clinical potential in the foreseeable future.

“…With the development of technology, microelectronic devices such as flexible electronics, wearable smart devices, and portable electronics are being used increasingly widely. − Microelectronic devices are limited in size, and their energy storage devices need to be adapted to them in terms of space and structure. , The all-solid-state thin-film lithium battery is widely regarded for its high energy density, small size, safety, and structural designability, which can better meet the above requirements. − However, its application is limited by its thin electrode and low active material leading to low areal energy density and small overall capacity. Increasing the thickness of the active electrode (mainly the cathode) is an important way to improve the areal energy density and capacity of the thin-film battery.…”

Enhanced Interfacial Kinetics and High Rate Performance of LiCoO₂ Thin-Film Electrodes by Al Doping and In Situ Al₂O₃ Coating

The structure and surface-interface instability of LiCoO 2 thin-film electrodes during charge–discharge cycles are one of the main factors leading to the deterioration of electrochemical performance. Element doping and surface coating are effective strategies to tackle this issue. In this work, Al-doped and in situ Al 2 O 3 -coated LiCoO 2 composite thin-film electrodes are prepared by magnetron sputtering. The results show that the resultant composite thin-film electrodes exhibited excellent cycling stability, with a discharge specific capacity of 40.2 μAh um –1 cm –2 after 240 cycles at 2.5 μA cm –2 , with a capacity retention rate of 94.14%, compared to a discharge capacity of the unmodified sample of only 37.7 μAh um –1 cm –2 after 110 cycles, with a capacity retention rate of 80.04%. In addition, the rate performance of the prepared LiCoO 2 film is significantly improved, and the discharge specific capacity of the Al-doped sample reaches 43.5 μAh um –1 cm –2 at 100 μA cm –2 , which is 38.97% higher than that of the unmodified sample (31.3 μAh um –1 cm –2 ). The enhancement of electrochemical performance is mainly attributed to the synergistic effect of Al doping and in situ Al 2 O 3 coating. The metal Al forms a conductive network in the film, while part of the Al will enter the LiCoO 2 lattice to form a LiAl y Co 1– y O 2 solid solution, promoting the transport of lithium ions and improving the stability of the electrode structure. The in situ continuous deposition of the coating optimizes the active material coating–electrolyte interface.
