Luminescent materials have been widely used in the field of information security. However, single-mode anticounterfeiting technology with the aid of UV light excitation to generate visible-light emission is rough and easily decrypted. Herein, we build a novel information encryption and decryption technology

Therefore, applying acid-responsive POPs to optical anti-counterfeiting in practical applications is still challenging. Researchers often focus on generating new POP materials with different emission properties by choosing suitable structural units (aryl [14], thiophene [15], [16], or conjugated aromatics such as pyrrole).

When Gaston Planté invented the lead–acid battery more than 160 years ago, he could not have foreseen it spurring a multibillion-dollar industry. Despite an apparently low energy density—30 to 40% of the theoretical limit versus 90% for lithium-ion batteries (LIBs ...
Characteristics of Lead Acid Batteries
Information storage and security is one of the perennial hot issues in society, while the further advancements of related chemical anti-counterfeiting systems remain a formidable challenge. As emerging anti-counterfeiting materials, stimulus-responsive polymers (SRPs) have attracted extensive attention due t
AGM vs Lead Acid Batteries: 12 Key Differences Before we begin the comparison, it''s important to note that the AGM battery has its roots in the traditional lead acid battery.As a result, they do share a few similarities. Now, let''s see how each battery type
The widespread forgery in all kinds of paper documents and certificates has become a real threat to society. Traditional fluorescent anti-counterfeiting materials generally exhibit unicolor display and suffer greatly from substitution, thus leading to a poor anti-counterfeiting effect.
